1. Clean the whole vehicle. Clean the whole vehicle with a paint cleaner with strong detergency. When using cleaning agent, it is necessary to avoid new scratches caused by particle dust during grinding.

2, water sandpaper grinding. For coarse particles, fine sandpaper marks, flow marks and other defects. On the surface of the coating, before polishing, use 600#~ 1000# water sandpaper to dip the small rubber pad in water, and gently polish it until it is flat (be careful not to wear through the paint layer).

3. Rough grinding and fine grinding. Roughly grind the traces of water sandpaper with machine grinder (electric or pneumatic) and coarse grinding paste; Then polishing and fine grinding with grinding paste.

Step 4 polish. The mirror polishing effect of paint film is achieved by using mechanical polishing machine and mirror treatment agent to remove the rotary printing left by rough grinding paste.

5. Glaze by hand. After polishing, wipe off the polished polishing paste, immediately wipe all the polished parts with cotton yarn dipped in varnish wax, and then wipe off the excess wax with dry cotton yarn to make the paint bright as a mirror.

After spraying the automobile surface, there may be some tiny defects on the surface of the paint film, such as coarse particles, sandpaper marks, flow marks, anti-white, orange peel and so on. In order to make up for these defects, grinding and automobile polishing are usually carried out after spraying to improve the mirror effect of the paint film and achieve the requirements of bright, smooth and gorgeous.

Extended data:

Automobile polishing is to polish the automobile first when waxing, sealing or painting in the process of automobile beauty. Because the glaze coating must be polished first, and it is a finely polished car to make a mirror.

This is a necessary operation for sealing glaze. Without polishing, the car paint is uneven, and the sealing time is very short, which can not achieve the effect of long-term adhesion at all, and it is no different from waxing. Of course, according to the situation of car paint, polishing does not have to be divided into three steps, and new cars are often repaired in one step. But the car with coarse wax must be polished with medium wax, and the car with medium wax must be polished with fine wax.

At present, there is a great demand for automobile polishing market, but the supply is slightly insufficient, especially there are not many enterprises with core intellectual property rights and excellent product quality, and the industry as a whole lacks brand effect. At the stage of strong demand, there is no doubt that the industry has huge demand and good development prospects.

However, how to maintain the healthy, stable and sustainable development of the industry requires the cooperation of Qi Xin, an enterprise in the industry, especially the spirit of critical research and development, to further improve production technology, reduce costs, truly solve the practical difficulties of customers, strictly control quality and provide the most reliable products.
