Polishing is not stripping, it requires skill and experience!
Finish polishing is an important part of automobile beauty, and the level of polishing technology directly affects the effect of automobile beauty. Its function is to remove the fine scratches and oxide layer of the paint, deal with the damage and stains of the car paint, superb construction technology can make the paint achieve bright and flawless, recovery as new effect. The work flow of paint polishing is to paint the abrasive agent on the grinding disk, and then stick the grinding disk on the turntable of the paint polishing machine, relying on the paint polishing machine to complete the paint polishing, the focus is on the adjustment of the speed and the choice of grinding materials. When carrying out the polishing operation, the following points should be noted:
When performing polishing operations, the following points should be noted:Select the grinding agent and grinding disc strictlyBefore polishing, check the finish carefully. Depending on the size of the scratch on the paint, the degree of damage, the thickness of the paint, the wear resistance and other specific conditions, choose different grinding disks and abrasives.Water-based abrasive can not cover small scratches, grinding as far as possible to make the grinding disk and paint surface contact operation. When the abrasive dries and adheres to the surface of the paint, spray a small amount of water on the grinding platePerform the grinding.
Oily abrasive, can cover small marks, not easy to appear abrasive dry attached to the surface of the paint, after grinding need to be degreased with degreasing water, and then you can do plating crystal, coating products, otherwise plating crystal, coating can not be well attached to the surface of the car paint, easy to be cleaned off.In the case of relatively large scratches on the paint, wool tray with coarse abrasive (4um) can be selected; Medium scratches can be selected with thick sponge ball with medium abrasive (2um); Fine scratches can be selected fine sponge ball with fine abrasive (0.8μm) for polishing operations.Under normal circumstances, choose medium abrasive with wool plate grinding, and then use fine abrasive with sponge ball grinding, "the right medicine" polishing can make the paint to achieve a more perfect effect. Polishing machine speed control is not good may throw through the paintWhen polishing operations, we must strictly control the speed of the polishing machine, for skilled technicians, the steel plate part of the paint can be controlled between 2500-4000 RPM, the plastic part of the paint does not exceed 1800 RPM. For unskilled technicians, the paint of the steel plate part should be controlled between 1500-2500 RPM, and the paint of the plastic part should be controlled between 1000-1200 RPM. Otherwise, the high temperature caused by too fast speed may cause damage to the paint, or even throw through the original paint, resulting in irreparable losses.The most effective polishing sequence is from inside to outside, from top to bottom, turning around the car to complete the job.
