Car paint and daily protection knowledge of paint

carThe paint is generally baked paint. In the car factory, the frame and the body are welded, and after the body is manually repaired, the next process is painting. Generally speaking, the first is the primer. Dip the white leather car body into a syrup-like paint tank, take out the drying primer; then send it to a dust-free workshop, spray the top paint with electrostatic spraying process, and then dry it at a temperature of about 200 degrees. Some will apply a layer of varnish.

In this way, the paint process is complete. There are several general topcoats: ordinary paint, metallic paint, pearl paint. The main components of ordinary paint are resins, pigments and additives; metal paint has more aluminum powder, so it looks bright after completion; pearl paint is added with mica particles. Mica is a very colorful effect. If it is a metallic paint plus a varnish layer, the car paint looks dazzling.

Pay attention to daily maintenance

1. Before, during and after the vehicle is used, the dust on the car body should be removed in time to minimize the adsorption of dust on the car body by static electricity;

2. After rain and rinse. After the rain, the rain stains on the car body will gradually increase. If the rain stains are not washed with water as soon as possible, the surface paint will be damaged over time.

3. When washing the car, wait until the engine has cooled down. Do not wash the car under the scorching sun or high temperature to prevent the detergent from being dried and leaving traces. Usually, you should use special detergent and neutral running water to wash the vehicle by yourself. Do not use alkaline detergent, soapy water and detergent to prevent the grease in the southern surface of the paint from being washed off and accelerate the aging of the paint surface.

4. Clean the vehicle with a clean, soft cloth or sponge to prevent mixing of metal and sand. Do not wipe the vehicle with a dry cloth, towel, or sponge to avoid scratches. When wiping, wipe gently from top to bottom along the direction of the water flow, and should not wipe in circles and horizontally.

5. Some special extremely corrosive traces (such as asphalt, bird droppings, insects, etc.) should be removed in time. In this regard, it must be cleaned with a special cleaner, and do not use a blade to scrape or use gasoline to remove it, so as not to damage the paint surface.

Precautions for touch-up paint

First of all, all places, even in the original factory, will not use any "original paint" for touch-up paint! If the repair shop tells you that they use "original paint", it must be lying to you, in order to increase maintenance costs. The reason is simple: after the original factory spray paint process is sprayed, it is baked at a temperature of 200 degrees. With so many parts on the finished car, how many can withstand a temperature of 200 degrees?

But under normal circumstances, the manufacturer will still recommend the designated brand to the specialized repair stationRefinish paint.

Secondly, the color of the refinish paint is all formulated before the repair. The reason is also very simple: your car may have been driving for a few years, and the paint has begun to fade, although you can't tell. If you park outside, the degree of fading in different directions will be slightly different. If you want to match the original color as much as possible, you can only adjust it now. The computer color matching of a large repair shop, the color difference between the paint and the original paint is really indistinguishable by ordinary people's eyes. You can rest assured.
