How to remove paint spots on cars?
1. A large amount of dirt on glass can be removed by using soap and a proper amount of mixed solution of ammonia and turpentine.
2. Repeated pasting and tearing with transparent adhesive can remove some stains.
3. Rub it with essential balm. This thing is very easy to buy. ?
4. Paint can be wiped off with 4b glue, which is a very soft Korean glue.
5. It's best to wipe with special cleaner if possible. ?
6. blow dry with a hair dryer first, and you should be able to scrape it off after scraping.
Extended data:
The paint is a viscous oily pigment, which is flammable under wet conditions, insoluble in water, slightly soluble in fat, soluble in alcohol, aldehyde, ether, benzene and alkane, soluble in gasoline, kerosene and diesel oil.
Paint, regardless of its variety or shape, consists of three basic substances: film-forming substance, secondary film-forming substance and auxiliary film-forming substance:
Film-forming substances: also known as adhesives, film-forming substances are mostly organic polymer compounds, such as natural resins (rosin, paint) and coatings (tung oil, linseed oil, soybean oil, fish oil, etc.). ), synthetic resin and other mixed components are formed by high temperature reaction, and some of them are inorganic coatings (such as inorganic zinc-rich coatings). Various film-forming substances are classified as ***xxx according to the national standard. It is the main body of paint and determines the performance of paint film. If there is no film-forming substance, pure pigments and auxiliary materials cannot form a paint film.
Secondary film-forming substances: including various pigments, physique pigments and antirust pigments. Pigment provides color and hiding power for paint film, and improves the protective performance and decorative effect of paint. Pigments with good weather resistance can improve the service life of coatings. Constitution pigment can increase the thickness of paint film, and make use of its "flake-like, needle-like" structure to form a fish-scale paint film through the accumulation and overlapping of pigments, thus improving the service life of paint film and the waterproof and antirust effects. Anti-rust pigments can prevent the surface of objects from being corroded by atmosphere and chemicals and the surface of metals from being corroded through their own physical and chemical anti-rust effects.
Auxiliary film-forming substances: including various additives and solvents. Various additives play a very important role in the production process, storage process, use process and film forming process of coatings. Although the dosage is small, it has a great influence on the performance of paint film. It can't even form a paint film, such as drying, sinking, caking and crusting.
Waterborne paints need additives to meet the requirements of production, construction, storage and film formation. The level of paint additives also represents the paint level of a country. Solvent, also known as "dispersion medium" (including all kinds of organic solvents and water), mainly dilutes film-forming substances to form viscous liquid, which is convenient for production and construction. The mixture of film-forming base material and dispersion medium is usually called coating.
