Why can't you see the lines on the surface? You can only see the point model tree.
How can I choose a good film that suits me? After reading the following series of posts, you will understand.
First, the classification characteristics of solar films
In the past, car film can be divided into two categories, one is ordinary solar film and the other is explosion-proof film. Now the third generation of ultra-infrared ceramic nano-technology solar film has appeared. So what's the difference between the three?
Material: explosion-proof film is plated with metal on the basement membrane, while ordinary explosion-proof film is coated with a layer of color on the basement membrane, and some ordinary explosion-proof films are coated with aluminum powder, so the reflective materials are very different.
Explosion-proof: Explosion-proof membrane can play an explosion-proof role. Maybe some car owners don't understand this very well. The front windshield related to the owner's interests is a double-layer structure, so there is no need to "gild the lily". However, in the event of an accident, in fact, many car owners will still be stabbed by tiny pieces of glass, and we can also see car owners with blood all over their heads from TV pictures. Sticking explosion-proof film, because it is made of multilayer plastics, has strong adhesion tension, which can greatly reduce the chance of glass breaking. Replaced with ordinary solar explosions, most of them are single-layer structures, and their anti-explosion ability is weak.
Ultraviolet protection: ultraviolet rays will burn our skin, and they will not let go of the leather seats in the car. Therefore, the anti-ultraviolet function of explosion-proof membrane is very important. At present, the anti-ultraviolet rate of most brands of explosion-proof films on the market has reached more than 98%, while the anti-ultraviolet rate of ordinary solar films is extremely low, only one tenth of that of explosion-proof films. So the advantages and disadvantages of the two are clear at a glance.
Thermal insulation rate: This is the function that the owner is most easily affected by the explosion-proof membrane, so it becomes one of the standards for the owner to identify the quality of the explosion-proof membrane. As long as the owner is in the construction workshop, he can feel the heat insulation effect by touching the membrane with his hand through the detector set in the workshop. However, the thermal insulation capacity of general solar films is very limited, while the thermal insulation rate of explosion-proof films reaches 80%.
Perspective: As long as you pay a little attention, you will see some coated car side windows, and there is always a blank near the rearview mirror. Because the transparency of some films is too poor, it naturally affects the owner to look at the rearview mirror, so the owner will do this. In fact, the high-transparency explosion-proof membrane can see high brightness, and the owner does not need to worry about the bad sight after installation. Therefore, when buying a film, you should be careful whether you pay attention to light or price.
Wear resistance: Private car owners generally develop the habit of grooming their cars regularly, one of which is car washing. In the case of frequent car washing, ordinary solar films are easy to leave scratches, while good explosion-proof films are not easy to be scratched because of their hardness treatment and strong wear resistance.
Color: Due to different materials, the aluminum powder coating is easy to oxidize and turn black during use, while the metal film remains relatively stable for a long time.
How does nano-space film play a role in heat insulation?
The solar spectrum radiated to the earth can be divided into three bands: 200-370 nm band is ultraviolet band, which has strong penetrating power and can reach the depths of human skin and cause skin pigmentation and aging; 380-780 nm is the visible spectrum band, which has no direct harm to human body; 850-4000 nm is an infrared spectral band with high heat. So what people usually call heat insulation and sun protection refers to the function of effectively blocking ultraviolet rays and absorbing infrared rays. The nano-spacer film selectively absorbs light, and the blocking rate of ultraviolet rays is close to 100%, the transmittance of infrared rays is 20%, and the transmittance of visible light is over 80%.
The principle of "metal reflection" used in solar films of ultra-infrared ceramic nanotechnology is different from many explosion-proof films. As we know, the explosion-proof film achieves the purpose of heat insulation and sun protection through the reflection and scattering of light by metal, so the metal film like this is light-transmitting on one side, which is the "mirror effect" we usually see after the car is pasted with film. The use of nano-materials can be compared to a "sieve" because it selectively transmits visible light and reflects ultraviolet rays, infrared rays and other rays harmful to human body. In addition, due to different materials, nano-films are not as easy to fade as metal films.
In addition to the product itself, it is worth mentioning the business philosophy of membrane rice space membrane. The seller thinks that nano-space film is only a semi-finished product, and after-sales service is the finished product. So they put special emphasis on installation technology. Generally, it takes 3-4 hours for peers to complete the work, while their installation only takes 1 hour. Adopt assembly line operation mode. Step one, covering the film; Every two steps: shaping; Glass cleaning every three steps; The fourth step, filming. There is a special person in charge of every step.
The definition of high-quality car film should be more than 6 meters at night, while the definition of inferior car film is poor, especially at night, and the sight of both sides and rear windshield is unclear.
2, feel
High-quality film feels thick and smooth, while inferior film feels thin and brittle, and it is easy to wrinkle.
Step 3 color
The pigment of high-quality film is dissolved in the car film, which is durable and not easy to change color, and it will not change color when scraped with a scraper during the pasting process. The color of the inferior film is in the glue. Tear off the lining of the car film, and after scraping it with nails, it will lose its color, and the place where the film was scraped by nails will become transparent. In the process of sticking film, when scraping film, sometimes the color will fall off by itself. This film will change color that year, and the fading will be more obvious after one year.
4. Bubbles
When the plastic lining of the car film is torn and reassembled, the inferior film will bubble, while the high-quality film will be intact after reassembling.
5. Thermal insulation performance
Thermal insulation is an important index of solar film, which is difficult to distinguish with the naked eye and hand. It can be compared by a simple test method: if a piece of glass stuck on the car film is placed on the iodine tungsten lamp, the high-quality film will not feel a trace of heat by hand, but the feeling of heat immediately indicates that its heat insulation performance is faulty and inferior.
Third, the film precautions
Pay attention to the following aspects during specific operation:
1. Keep the environment clean where the solar film is pasted. Don't use electric fans, and don't build them on the roadside.
2. The window glass must be absolutely clean and cleaned repeatedly. If there are dust particles on the glass, it will affect the adhesion and clarity of the solar film.
3. The solar film is only attached to the inside of the glass.
4. The predetermined type of surface. It is not difficult to stick the solar film on the flat side window glass, but it is very technical to stick it on the curved front and rear windshield. Generally, the outer sides of the front windshield and the rear windshield are used as models for heating the solar film to a predetermined shape. The predetermined method is to spread the protective film of the solar film outside the curved glass, sprinkle water between the solar film and the glass, heat the solar film with a temperature-adjustable blower, and squeeze bubbles and water on the glass with a plastic scraper while heating, so that the solar film is deformed until it completely conforms to the curved glass. It is important to pay special attention to that the heating should be uniform and not too concentrated, otherwise the glass may crack if the temperature is too high.
5. movies. Spray clean water on the inside of clean glass, then tear off the protective film of the solar film, spray clean water on the pasted surface, then stick the solar film on the glass, and then squeeze it with a plastic scraper to remove bubbles and excess water in the solar film. For curved glass, if individual parts do not match, it can also be deformed by heating with a blower to achieve complete matching. After drying, the solar film can be firmly attached to the glass.
6. Because the solar film is attached to the inner side of the window, clean water should be sprayed in the inner space before pasting the film to let the dust particles sink as soon as possible. Don't use air conditioner in the car, although the temperature inside is very high.
Fourth, movie tips
It often rains, so many new car owners are not in a hurry to film. But anyone with a little beauty knowledge knows that the amount of ultraviolet radiation will not be greatly reduced because of the dark weather. High-quality explosion-proof membrane not only maintains the heat insulation function, but also has the function of isolating ultraviolet rays, which not only prevents the skin from being sunburned and aged by ultraviolet rays, but also protects the beauty of the instrument panel.
Many car owners already know that sticking explosion-proof film should go to a decoration shop with indoor film pasting conditions; Professional decoration shops will keep indoor humidity properly before pasting the film to avoid sand, bubbles and scratches caused by dust. But most car owners may not know that on cloudy days, the air humidity is higher, static electricity is reduced, and indoor and outdoor dust is also significantly reduced. This is the best time to film. After the collision, tempered glass will break into small and smooth pieces. Although it won't hurt passengers, splashing glass may still cause injuries. Adding 2-4 layers of explosion-proof film with explosion-proof base material to heat insulation paper can bond the glass into a whole, and even if the glass is broken, its fragments will not splash.
The front barrier film coated with precious metals on the substrate is particularly clear, and the heat insulation effect is greatly enhanced than that of ordinary films. The driver's dizziness caused by using ordinary membrane as front barrier membrane will be completely avoided.
Throughout the winter, cars always drive with closed windows and insufficient sunshine, and the air in the compartment is turbid; Interior decoration is dark and bacteria breed; Cushions, carpets and other fluff positions are covered with mites. As the weather gets warmer, these mites will multiply in large numbers, causing allergies, rhinitis, asthma and other diseases. So when spring comes, you must give your car an internal cleaning and sterilization care.
Professional car cleaning and beauty procedures are rigorous and complicated. First of all, use a high-powered vacuum cleaner to absorb the dust on the surface and deep. Our general household or car vacuum cleaners have low suction, and deep dust cannot be sucked out. After vacuuming, spray the special fluff cleaning solution on the velvet parts such as the roof, carpet, velvet seat and door help. Brush thoroughly and blot the stain with a cotton towel. Due to the mild nature of the fluff cleaning agent, the washed flannel is fluffy and soft, leaving no stains. If it is a leather seat, it is necessary to use leather plastic care agent for cleaning and nursing, so as to achieve the effect of cleaning and keeping the leather soft. Plastic parts such as dashboard, steering wheel and gear area. It should also be thoroughly scrubbed. If the dust at the air outlet is too thick, it should be removed.
After cleaning the car, clean the trunk. Many drivers use the trunk as a storage box, and the trunk has become the dirtiest place with the most bacteria in the whole car. When cleaning, all sundries should be taken out and thoroughly scrubbed with liquid medicine.
After the whole car cleaning is completed, the second step: high-temperature sterilization, which is what we often call car sauna. Because many bacteria, such as mites, can't be seen by naked eyes and can't be brushed off, we have to heat the disinfectant to 100 degree with a car steam engine and then atomize it. When the car and trunk are filled with atomized liquid medicine and closed for 10 minute, the liquid medicine can completely penetrate into the car, achieving the effect of disinfection and sterilization, and leaving a faint fragrance.
After sterilization, the next process: polishing care. After cleaning, the plastic parts in the car should be coated with protective agent, that is, brightening and brightening, and at the same time preventing the decorative parts from fading and aging. In order to save trouble, some beauty shops spray canned facial wax on plastic parts, which is not conducive to the penetration of protective agents, and will also splash on windshield or car paint to form oil spots. It brings difficulties to the last step of glass cleaning, leading to the phenomenon that the front windshield is stained with oil for a long time. The correct way is to gently apply the plastic protective liquid to the corresponding position with a soft towel, and finally wipe off the oil slick with a clean towel. If the original seat cover and foot pad in the car are too old, it is recommended that everyone replace them together to ensure the thorough and fresh air in the car. The trunk should also be equipped with molded trunk mat and storage box to prevent it from being polluted again by oil or other dirty things.
Maintenance of paint layer
When a car drives outdoors for a long time, it is inevitable that dust will fall. Generally, it only needs to be washed with clean water regularly. But if some organic matter sometimes sticks to the car body, it will be in trouble. For example, some trees will secrete a resin, which will stick to the car body when scraping branches; Bird droppings are also a difficult thing to deal with; In some areas, the weather is very hot, and asphalt will fly quickly in the car. If it is not removed in time, it will corrode the car paint for a long time. If you encounter acid rain or sandstorm, you need to clean the car body in time.
With the development of automobile service industry, various automobile beauty products came into being. As long as you go to the automobile maintenance products market, you will find many maintenance products and tools to choose from. For example, there is a washing tool for household car washing, one end of which is connected with a faucet and the other end is a pressurized shower, which can be easily cleaned by itself. It doesn't matter if there is no sewer around. It can be dry cleaned. There is a special bottled car body cleaner, which can be sprayed on the car body and scrubbed with a soft cloth. In order to effectively protect the paint film, it is best to wax the car body when you just buy a new car. Waxing can not only protect the paint surface, but also increase the brightness and make the car shine.
Imported cars in the 1980s, especially some vans, began to rust within seven or eight years. Due to the low technical level at that time, the design life of this car was only 7 or 8 years. At the end of life, there will naturally be many diseases. So at that time, the state stipulated that motor vehicles would be scrapped after 10 years. In 2 1 century, the situation has changed a lot. Automobile factories all adopt double-sided galvanized steel plates, and the whole body has been painted by electrophoresis, and the internal pipe holes have also been waxed. Therefore, the anti-rust ability is greatly improved, and the service life of automobiles generally reaches more than 15. Therefore, the compulsory retirement period stipulated by the state has been extended to 15 accordingly. But there is one thing to note. If the car body collides, the car body steel plate will wrinkle, the paint surface will be easily damaged, the steel plate will be exposed and rusted, and the painting must be repaired immediately.
Paint layer is different from metal, which has low hardness and is easy to be damaged. Therefore, when cleaning or polishing, you must use a soft suede, cotton cloth or wool brush, otherwise it will be scratched and self-defeating.
What annoys the car owners is the car body scratches, some of which are accidentally scratched while driving, and some of which are scratched by urchins or passers-by with hard objects for no reason. Those ugly scratches often cost the owner a lot of money. Because to mend this line, you need to polish the whole piece and spray it again. Otherwise, all the repair marks will be exposed to the sun. In order to solve this problem, developers have also developed various complementary color pens, but the repair process is not simple and the price is not much cheaper. The best way is to drive carefully and choose a good parking place. The car has been used for a long time, and it is inevitable that the paint will fade, turn white and darken more or less. This is because the main component of paint is organic chemicals, which will oxidize and deteriorate under long-term ultraviolet radiation. Generally, frequent cleaning can reduce the fading phenomenon; Mild fading can be waxed and polished, moderate fading should be ground, and severe fading can only be repainted.
Nowadays, many people like metallic paint, which looks bright and beautiful. The flash component in metallic paint is mainly aluminum powder, which is more prone to oxidative cracking. Therefore, metallic paint needs more care, and it is often polished and waxed.
Polishing and waxing is not difficult. If you are willing to do it, you can solve it yourself. There are all kinds of wax polishes on the market, both liquid and waxy, so you can choose them yourself. After cleaning the car body, pour some on the car body, and then gently and evenly coat the car body with soft wool, cotton cloth or gunny leather. It doesn't need to be hard. Thin. The first floor, not very thick, but very flat and uniform. Don't operate in the sun, and the surrounding environment should be clean. After waxing, wait for an hour or two before leaving the car. This is to give the wax layer a time to attach and cure. Maintenance of Body Plastic Parts
There are a lot of plastic parts inside and outside the car body. If they are dirty, they should be cleaned in time. However, it should be noted that organic solvents should not be used for cleaning, because organic solvents are easy to dissolve plastics and make plastic parts lose luster. So try to scrub with water, detergent or soapy water. Be careful not to let water seep in places like the dashboard, because there are many wire connectors below, which are easy to cause short circuit. Artificial leather is prone to aging and cracking, so it is best to coat it with a layer of leather protective agent.
Maintenance of window glass
The window is dirty, so you can use the window cleaner in the liquid storage tank to clean it. Of course, you can also scrub with clean water. But the efficiency is not so high and the brightness is not enough. At the same time, because the oil film cannot be cleaned, it is easy to produce seven-color spots in the sun, which affects the driver's sight and must be removed as soon as possible. There are special glass cleaners on the market, and it would be more ideal to spray a layer of window glass coagulant. This is a kind of silicone compound, colorless and transparent, water is not easy to stick to it, and it will automatically form water droplets to fall off. When it rains lightly, you can drive even without a wiper. In high temperature area, the window glass must be protected by reflective film. On the one hand, it can prevent ultraviolet rays from entering, on the other hand, it can reflect infrared rays that cause thermal effects as much as possible. Some cars have a protective film on their cars, and they use laminated glass, and the protective film is centered in the middle of the glass. This is the best way. Some cars are not pre-installed with protective film, so you have to put a layer on them. The first generation of protective film used in the past, which is dark in color, can only block a small part of ultraviolet and infrared rays, and often affects the driver's sight. Now the new generation of protective film can basically filter out all ultraviolet rays, the transmittance of infrared rays is less than 20%, the visible light can be automatically adjusted, and the driver can still see the surrounding things through the protective film. In addition, this film is also very strong. Sticking to the glass can effectively prevent the glass from bursting. Even if the glass is broken, it will stick to the protective film and will not splash and hurt people.
There is a silver reflective film that can't be used. Although it is beautiful, you can see the outside from the inside, but you can't see the inside from the outside. But the reflected light is easy to dazzle others and cause light pollution. It's banned now.
Clean tires
Just as the car body needs to be beautiful, tires are more likely to get dirty because they are in direct contact with the ground. Generally, dust and soil should be washed with water. However, if asphalt, oil stains, etc. Stick to it and you won't be washed away. Now there is a special pressure tank tire cleaner, which can dissolve these dirty things and make the tire look brand-new as long as it is sprayed on the side of the tire. Maintenance of car body interior
The maintenance of the interior of the car body is very important. It is directly related to the health of passengers.
The space in the carriage is very small, so it is obviously not enough to breathe only by this air when fully loaded. Therefore, there are many people on the bus. If you sit for a long time, open the window in time to let fresh air in. Even if the air conditioner is turned on in summer, the vents on both sides of the dashboard should be opened to avoid lack of oxygen.
The interior of the car body should not only be ventilated frequently to replenish fresh air, but also be cleaned frequently to remove dirt such as dust, which often contains a lot of bacteria. It is reported that more than 20,000 mites can be removed from car seats. Especially suede fabrics, it is easier to hide evil people and shelter evil people. In addition to using brushes, vacuum cleaners and other tools, you can also scrub the interior with industrial ammonia water that permeates 3 to 4 times the water. Sometimes you can spray some disinfectant pesticides, but then you must open the doors and windows of the car to discharge aerosol.
Car carpets (or car mats) should always be taken out, patted and cleaned. At present, there are some good car carpets, which are not only beautiful in color and shape, but also woven into a special grid structure, which is convenient for shooting embedded sand, dust and so on.
There are spray detergents specially used for fabrics on the market. After spraying on the fabric, it is easy to wash off the dirt after leaving it for a few minutes.
For genuine leather or artificial leather, we should always wipe it with special leather protectant, which can not only keep the leather clean and bright, but also prevent cracking and prolong its service life.
As long as you visit the market with your heart, you can find all kinds of special protective articles for automobiles.
In our concept, car washing should be a very easy thing, but when you paint your car with scratches all over, you will know that car washing is not as simple as you think. Although it is the most basic lesson of automobile beauty, you also need to master some knowledge. Here are some tips for car owners who are willing to wash their own cars:
Car washing should be carried out in a cool state of the car body, where there is no wind and direct sunlight, and it should be cleaned with a towel or sponge. It is best to wash the car in the order of the roof, hood and sides, and at the same time clean it around the car body in a certain direction, so that the decontamination effect is better. You'd better use detergent when washing the car. Because foam can avoid scratches, and it can be brushed thoroughly, and it can clean up the oil stains accumulated on the car body due to exhaust gas, rain and snow. Car wash liquid is divided into light paint, dark paint and silver paint, and different color bodies should be selected separately. Don't throw away the remaining cleaning agent immediately after washing the car. It can clean tires, rims and exhaust pipe outlets. After the water washing is completed, it is followed by wiping the body. Deerskin is the best car cleaning material, which is usually available in car washing boutiques. Usually, it is best to prepare two pieces to clean the car body and window respectively.
After washing the car, the next step is waxing. Similarly, waxing is best done when the car body is cooled, and it must be done after washing. Waxing sequence, like car washing, is also carried out from the car body down. Furthermore, the direction of pushing wax with a sponge is not an arc in the traditional concept, but a position 90 degrees relative to the direction of the car. Pay attention to the details when waxing. These places can be waxed with emulsion or liquid wax, or with spray brush. As for wheels, rims and other parts, try to use special wax.
If necessary, we can also clean the car, which can deodorize and remove parasites, so we should clean the car at least once a month. When washing the car, take out the pedal pad for cleaning and put it in the shade to dry. Then wipe the interior of the car with internal cleaner and rag, starting from the inner roof, inner door, steering wheel, gear lever and audio panel, and wiping from top to bottom. Dirt on plastic skin or lines should be scrubbed with a small soft brush dipped in detergent. At the same time, when cleaning the car, pay attention to separate it from wiping the rag outside to avoid polluting the car.
Finally, use a vacuum cleaner to remove dust from carpets and corners. Then your car will look brand new. With these tips, you can be a car beautician yourself with confidence.
When the sun is like fire, not only do we suffer, but cars also suffer. How to make your car spend the summer? How can we avoid traffic accidents caused by the failure of the car itself? I think daily maintenance should prevent the following points:
(1) Anti-over-concentration of mixed gas Because of the high temperature, gasoline is easy to flow, and because of the expansion of metering holes, the gasoline flow rate increases, and gasoline is easy to evaporate, resulting in over-concentration of mixed gas. Therefore, it is necessary to adjust a small number of holes, adjust the position where the acceleration device is connected with the throttle rocker arm, appropriately reduce the oil level in the float chamber and reduce the oil supply.
(2) Preventing gas blockage In hot summer, the fuel system of gasoline engine is prone to gas blockage due to rising temperature, resulting in insufficient oil supply or even interruption of oil supply. In order to prevent air resistance, the gasoline pump can be separated from the exhaust pipe with asbestos pad, or the gasoline pump can be wrapped with wet cloth to cool down.
(3) Under the high temperature of evaporation prevention, the evaporation of oil and water will increase, and the oil tank cover should be tightly covered to prevent the oil pipe from leaking; Always check the water level of the water tank, the oil level and height of the crankcase, the brake fluid level in the brake master cylinder, the electrolyte density and level in the battery, etc. If there is any discrepancy, it should be supplemented and adjusted in time.
(4) Anti-overheating In order to prevent the engine from overheating, it is necessary to pay attention to the fact that the fan belt can not be stained with oil to prevent slipping during maintenance, and the belt tightness is appropriate. Rest in time when driving, try to choose a cool place when resting, and open the hood to ventilate and dissipate heat. When the tire pressure rises due to heat, stop to cool down, and do not use deflation or cold water to reduce the tire pressure and temperature.
(5) Anti-spontaneous combustion and self-explosion The summer temperature is high, and the daily maximum temperature is often above 35℃, which greatly increases the failure rate of the automobile itself. When the temperature is high, the heat dissipation is slow, and the temperature of the automobile water tank often affects the power of the engine, and may even cause mixed spontaneous combustion and self-explosion, which makes the engine unable to work normally. High temperature will also lead to the expansion and deformation of some parts, which will accelerate the wear of parts in light cases and burn out parts in heavy cases. In summer, the temperature of highway pavement is often above 70℃. Because of heating, the air pressure in the tire increases, and once it is driven for a long distance, it is easy to puncture the tire. When the above faults occur instantaneously, it may also lead to traffic accidents.
(6) Anti-poor lubricating oil is easy to dilute when heated, has poor oxidation resistance, is easy to deteriorate, and even causes failures such as tile burning and shaft locking. Therefore, crankcase and gearbox should be replaced with summer lubricating oil, and the quantity and quality of lubricating oil should be regularly checked and replaced in time.
(7) Car paint protects against exposure. Car paint is like human skin. It needs to be bright to make people love it. Although it looks lifeless, it is really afraid of the sun. Long-term exposure will make it old and wrinkled. Ordinary beauty protection, car washing and waxing, although some functions, will not have long-term benefits. Because any car wax contains silicon, long-term ultraviolet radiation will rust the car paint, leaving small black spots. Moreover, the abrasive particles in the car wax will leave tiny marks on the bright car paint. Car wax itself cannot enhance hardness and ultraviolet resistance, and it will be lost quickly because of high temperature. So park your car in the shade when you park.
