How to maintain table tennis board
2. Be careful not to hit the ball board or get wet. To keep the rubber clean, it is best to wipe it clean after playing, and then stick a protective film (usually sold in shops selling table tennis supplies) to avoid sun exposure and wet places, or near fire sources.
3, it is best to use it every day, this is the best maintenance method (often it will dry without glue! )
4, usually put in the bag.
The maintenance of table tennis bat can be simply summarized as three sentences: the bottom plate is moisture-proof, the rubber is anti-aging and the use is anti-falling. The specific methods are as follows: wipe the sweat stains on the racket with a dry towel after use, wipe the dirt on the leather with a wringing wet towel, cover the leather with polyester paper before it is completely dried, and collect the positive glue after the leather is dried. When collecting rackets, put them in a ventilated and dry place, away from heat sources, and avoid exposure to sunlight. Do not pile up heavy objects on the rackets.
Maintenance of rubber sheet
When you first learn to play ball, everyone will think that buying a good racket is the biggest investment, but after a long time, you will know that the rubber that is constantly changed is more expensive. Therefore, how to maintain the rubber to prolong its service life and how to judge when the rubber needs to be replaced have become the most concerned issues for golfers.
How long can a piece of rubber last? The answer varies from 3 days to 3 years, depending on the amount of practice. Most first-class players have to change the rubber surface every three days until 1 week. But this is what happens when you practice for five to eight hours every day and hit every ball hard. If you are an ordinary practitioner, it is enough to change the rubber surface once every 3 months.
The biggest enemies of rubber are sunlight and dust. Once the inner soft rubber surface is stained with dust or oil, the friction will be weakened. People who practice a lot must dip a soft cloth in water every two or three days to wipe off the dirt on the surface. Putting the rubber in a sunny place or next to a high-temperature stove, or in a heater or cold air outlet that blows out strong wind, will also shorten the service life. So the eraser must be put in the racket box. The prepared rubber sheets should be put in plastic bags to prolong their service life.
The maintenance of rubber also has a lot to do with the weather. The temperature in winter is low and the elasticity of rubber is not good; In summer or in areas with high temperature, rubber has the best elasticity and strong friction tendency, so the ball can fly far. In addition, when there is more humidity, the rubber is wet, just like a fog on the mirror. At this time, the ball is easy to slip. In the rainy season, it is especially necessary to remove the dirt on the rubber so as not to affect the friction of the racket.
There are many kinds of rubber covers in table tennis tools, but they can be roughly divided into two categories: reverse stickers and positive stickers. The back sticker includes back glue and arc-proof glue, and the front sticker includes front glue and raw glue. Because of the different rubber content, the reverse rubber has large friction, strong surface adsorption and adhesion, and the rubber is not easy to slide when it contacts the ball, which is beneficial to increase the rotation of the ball. In order to give full play to this characteristic, the most important thing when using reverse glue is to keep the rubber clean. Don't rub the eraser with greasy hands. After playing the ball every time, you can rinse the rubber with clear water and stick a protective film on it. If you have dirt that is difficult to remove with clean water, you can also use soap and other cleaning agents to clean it and dry it before using it.
According to rubber experts, rubber molecules are intertwined like lines. After vulcanization, sulfur molecules and rubber molecules will be arranged in an orderly manner. A new type of anti-sticking agent with good surface friction coefficient is mainly caused by the short head and gap of rubber linear molecular arrangement. However, the release agent becomes non-stick for two main reasons. First, the gaps between anti-sticking molecules are filled with dust and debris, which makes the anti-sticking surface physically change. Another reason is that the anti-sticking molecules further react with chemicals in the air, which leads to chemical changes on the bonding surface. According to the above principle, as long as you keep the playing environment clean and sanitary, and at the same time carefully protect your anti-adhesive racket like that old American man, the anti-adhesive life will definitely last longer.
When we choose a handy racket to practice, it is very important for people who want to play well to maintain and use the racket correctly and prolong its sports life, so as to avoid the discomfort caused by frequent replacement of the racket and increase unnecessary expenses.
A racket that conforms to the rules and can be used for formal competition consists of a bottom plate, a sponge and a rubber sheet. Let's introduce their respective precautions in maintenance and use.
The current trend of soleplate is different from that in 1960s, which is mainly reflected in two physical aspects. First, light weight: the current bottom plate is generally between 90-100g; Second, the thickness is thin: it was 6-7 mm in the 1960s, but now it is 5-6 mm. In order to pursue these two characteristics, and at the same time to maintain the good performance of "eating the ball without shaking hands and the bottom is strong enough", when selecting materials, it is necessary to choose lighter wood. In the process of use, in addition to keeping the bottom plate in a dry place to prevent heavy pressure and damage, special attention should be paid to the collision between the ball board and the table and the ground during playing. For example, when feeding more balls, you can use the spare board, and the chopper should keep a certain distance from the ground when practicing. More importantly, bad habits such as intentionally throwing the racket, hitting the table with the racket and hitting the baffle should be avoided.
The main factors affecting the properties of sponge are thickness, hardness, elasticity, pore size and number of holes. Because sponge is an expanding body, it should not be excessively pulled and stressed during use. When playing in a low temperature place, you should pay attention to proper heat preservation, because the bottom temperature will affect the elasticity of the sponge. People who use a single piece of rubber sheet and sponge sheet should use a fire-roasting electric perm head to iron the rubber sheet when replacing the rubber sheet, so that the glue between the rubber sheet and sponge can be fully dissolved and the sponge can be prevented from being damaged when replacing the rubber sheet. Glue can make the sponge foam and increase its elasticity, but when sticking to the bottom plate, use non-toxic special glue, which can protect both the sponge and the bottom plate.
In table tennis tools, there are many kinds of rubber covers, but they can be roughly divided into two categories, one is reverse stickers and the other is positive stickers. Reverse stickers include reverse glue and arc-proof glue, while front stickers include positive glue, raw glue and long glue. Because of the different rubber content, the reverse rubber has large friction, strong surface adsorption and adhesion, and the contact point between rubber and ball is not easy to slide, which is beneficial to increase the rotation of ball. In order to give full play to this characteristic, the most important thing when using reverse glue is to keep the rubber clean. Don't rub the eraser with greasy hands. After playing the ball every time, you can rinse the rubber with clear water and paste a layer of plastic film. If there is dirt that is difficult to remove with clean water, it can also be cleaned with detergents such as soap and dried before use.
The front rubber is low in rubber content, high in tooth hardness, low in friction, small in area and easy to slide because the rubber is in contact with the ball. Based on this feature, special attention should be paid to keeping the rubber dry when using positive glue. If you play in a wet place, you can wipe the rubber with a desiccant to reduce the humidity on the rubber surface. Generally, the bottom cover of rubber is relatively thin. When using a sponge, don't apply too much glue to the rubber at a time to prevent the rubber from being "rolled" and causing unnecessary losses.
