Don't neglect the maintenance of car paint

Car paints are divided into ordinary paints, metallic paints and pearlescent paints.

Automotive paints are divided into ordinary paints, metallic paints and pearlescent paints.

1, common sense of automobile paint:

For cars, car paint is not only decorative, but also has protective properties such as corrosion resistance, rust prevention, high and low temperature resistance, contamination resistance and impact resistance. Therefore, automobile paint is not only a simple layer like furniture paint, but generally consists of phosphating film, electrophoresis layer, intermediate paint, color paint layer and varnish layer. Among them, phosphating film and electrophoresis layer belong to primer, and color paint layer and varnish layer belong to topcoat.

Metallic paint: Also known as metallic flash paint, it is a popular automobile topcoat. Fine aluminum particles are added to the coating binder. After the light hits the aluminum particles, it passes through the air film and is reflected by the aluminum particles. Therefore, it looks like metal is shining. By changing the shape and size of aluminum particles, the flash of metal flash paint film can be controlled. Outside the metallic paint, a layer of varnish is added for protection.

Pearlescent paint: Also known as mica paint, it is also a popular automobile topcoat. Its principle is basically the same as that of metallic paint. It uses mica instead of aluminum particles. Its matrix contains mica pigment coated with titanium dioxide and iron oxide. When light shines on mica particles, it first appears the colors of titanium dioxide and iron oxide, and then complicated refraction and interference occur in mica particles. Meanwhile, mica itself has a special and transparent color.

In this way, the reflected light has a pearl-like flash. Moreover, titanium dioxide itself is yellow, which will turn light blue when squinted, and the color is different from different angles.

In addition to high hardness, metallic paint can also show the layered beauty of the car body. Another reason why "metallic paint" is becoming more and more popular is that it is mixed with metal powder and contains metal components, so the hardness of paint increases and the surface of paint becomes harder, so it is unlikely to be damaged. I cut myself.

Some plain paints are not metallic paints, such as white, black, bright red and yellow. Silver powder cannot be added to the paints of these colors, but after adding silver powder, the displayed color will no longer be the original positive color, but become white. It turns into pearl white, black into shiny carbon black, red into so-called burgundy, and yellow into gold.

Second, how to maintain the new car paint you just bought?

Although the new car paint has no aging problem, it should be completely protected before use, because the car paint has begun to contact the air, attacked by rain and dust, and began to oxidize. Timely and correct maintenance will protect your car paint.

1. Waxing new cars The first problem faced by imported cars is waxing.

Because most imported cars are transported by sea, in order to prevent the erosion of seawater, sea breeze and sunshine during transportation, automobile manufacturers will coat a protective wax on the paint of cars before they leave the factory. The wax body contains paraffin, resin, PTFE and other materials, which can keep the car body protected and anticorrosive for one year. Remove this layer of car wax, and finally don't wipe it with gasoline or kerosene. Use a professional wax solution or go to a professional beauty care shop.

2, cleaning the body surface If it is a domestic car, there is no saying of waxing.

But the best way to clean a car for the first time is to go to an indoor dust-free manual car wash shop or a garage with a better environment. Some pollutants are invisible to the naked eye, so the pollution of colloid, alkali, acid and other chemical components should be thoroughly removed. Simply using detergent can't remove these dirt, and it must be wiped bit by bit with special decontamination clay. And don't wax the new car casually. When someone buys a new car and waxes it, it is not worth it. Because there is a protective wax on the paint layer of the new car itself, premature waxing will remove the original wax on the surface of the new car, causing unnecessary waste. Generally, you don't need to wax a new car within three months after you buy it.

3. Paint maintenance in daily use In the normal use of vehicles, car waxing and paint sealing are problems that car owners are more likely to encounter.

As a traditional project of automobile beauty, the role of waxing is first to prevent water and acid rain. The protective effect of car wax will reduce the amount of water droplets attached to the car body. Secondly, it can prevent high temperature and ultraviolet rays, and the film formed by waxing can reflect some light, effectively avoiding the aging of car paint. Secondly, car wax can prevent static electricity, and of course it can also prevent dust. When the car is running, it will generate static electricity by friction with air, and car wax can effectively isolate the friction between the car body and air and dust. Without static electricity, cars naturally have less dust adsorption, and car wax can also play a role in polishing, making cars look as bright as new.

Third, how should the owner maintain the car paint daily?

The correct way to protect car paint;

1. Park your car in the garage as much as possible. When parking, don't be exposed to strong sunlight to reduce rain.

2. Don't dry-clean the car, the small sand on it may wear the paint surface, so be sure to rinse it with water.

When the car is just bought back, it should be glazed once, and then polished less and waxed more.

Don't leave it lying around when you go out to park. If you get in the way, you'll get someone to paint the car.
