Car paint, likecarThe outer layer of "skin", "skin" is well maintained, it will look bright and beautiful. Car paint not only gives the car a dazzling appearance, its excellent protective performance, but also prolongs the service life of the car. So, in our daily car life, how should we protect the "skin" of our car?
If you want to protect the "skin", you must first understand what the "skin" is made of.Under normal circumstances, automobile paint is composed of three parts: primer, intermediate coating and topcoat. Automotive topcoats are mostly composed of film-forming substances, pigments, solvents and additives. Pigment is the material of the top paint color, which does not volatilize. It gives the paint the hiding power; the film-forming material is the material that determines the type of paint, generally composed of natural resin or artificial resin, and its function is to keep the pigment in a bright state and make it It is strong and durable and can adhere to the surface of the car body; the solvent is an easily volatile component in the paint, its main function is to fully dissolve the resin in the paint film, so that the paint can be applied normally; the proportion of additives in the paint generally does not exceed 5% , Plays the role of accelerating drying and enhancing gloss, and can improve the chemical resistance of car paint.
After understanding the basic knowledge of car "skin", we must begin to pay attention to all aspects of maintenance work.
1) Daily car paint maintenance
Since car paint contains organic ingredients, it will oxidize itself, weather, and deteriorate. As a vehicle, long-term wind and sun will quickly lose its original luster and reduce its protective function. The dust, wind and rain in the natural environment have caused a lot of damage to the paint of the car, and thorough cleaning is essential. The stains on the car paint can be treated in different ways. For the asphalt, the asphalt spots on the car can be removed with a professional de-asphalting water; in the case of tiny scratches, it should be partially polished and polished with abrasive sandpaper; it can also be used for the whole car. Wax polishing, etc., these are all ways to keep the paint surface of your car youthful.
2) Car paint maintenance after rain
Rainwater is slightly acidic. After it rains, as the rainwater on the paint surface evaporates, the local acid concentration will show an upward trend. If rain stains on the car paint surface are not cleaned as soon as possible, the paint surface will be damaged over time. A lot of rain stains are generally more on the front cover of the car, because the engine will generate a lot of heat when the car is working, and the rain will evaporate quickly at this time, and the watermark will appear. If the watermark penetrates deeper, only waxing is used. If it doesn't fall off, it usually needs to be polished by the static surface wax. The function of the static surface wax is to restore the brightness of the car paint, and then wax it.
3) Snow car paint maintenance
Snow also has a great impact on the paint. Snow contains a lot of corrosive substances such as acid, alkali or salt. If the snow covering the car is not removed in time, the car paint will be corroded by the corrosive components in the snow. , Over time, it may rust the car paint, make the exterior bright glaze lose its luster, and cause the car paint to peel off in severe cases. Therefore, it is best for car owners to wash the car immediately after snow, even if the weather forecast shows that it will snow in the next few days, do not drag the car without washing it. Washing the car immediately after snow will protect the car very well.
