Tools for using abrasive products and precautions

Grinding is the second stage of the lacquer care process, which removes dirt from the paint surface by surface pretreatment, eliminating severe oxidation and slight scratches or surface defects. According to the operation method, it can be divided into manual grinding and mechanical grinding. It can be used for the grinding treatment of paint enamel, which can remove the slight whitening, scratches, sandpaper marks, glazed surface loss, distortion, tar, paint mist and acid rain mark. In order to provide a good substrate to meet the polishing requirements, it is a guarantee that the paint film is flat and durable. The products and tools used in the grinding of automobile maintenance and maintenance nets are mainly abrasives. The abrasives can be divided into physical cutting abrasives, chemical cutting abrasives and various cutting methods according to the cutting method. Agent. There are two kinds of physical cutting methods: pumice rock type and clay type; chemical cutting type has micro crystal type; and various cutting methods are mainly neutral abrasives. The main characteristics of the pumice-type and clay-type abrasives are that the material is hard and the cutting speed is fast. The particles are rubbed with the paint layer to generate high heat to remove the flaws on the surface, but the particle volume does not change due to the cutting speed and particle size during the operation. If the operator does not understand the thickness of the paint film, the technique is not proficient and it is easy to wear the paint layer, so it is only suitable for the highly skilled professional. The main feature of the microcrystalline abrasive is that the microcrystalline particles can be gradually decomposed by the heat generated by the friction, and the volume thereof is gradually reduced during the operation, and the extremely high temperature is generated to remove the oxide layer, and the surface paint layer is dissolved. Partly fill the pinhole of the recess. Medium Grinding is the second stage of the lacquer care process. Surface pretreatment removes dirt from the paint surface, eliminating severe oxidation and slight scratches or surface defects. According to the operation method, it can be divided into manual grinding and mechanical grinding. It can be used for the grinding treatment of paint enamel, which can remove the slight whitening, scratches, sandpaper marks, glazed surface loss, distortion, tar, paint mist and acid rain mark. In order to provide a good substrate to meet the polishing requirements, it is a guarantee that the paint film is flat and durable. Car maintenance and care network

 

Products and tools used for grinding

 

The products required for grinding are mainly abrasives, and the abrasives can be classified into physical cutting type abrasives, chemical cutting type abrasives, and various cutting type abrasives according to the cutting method. There are two kinds of physical cutting methods: pumice rock type and clay type; chemical cutting type has micro crystal type; and various cutting methods are mainly neutral abrasives.

 

The main characteristics of the pumice-type and clay-type abrasives are that the material is hard and the cutting speed is fast. The particles are rubbed with the paint layer to generate high heat to remove the flaws on the surface, but the particle volume does not change due to the cutting speed and particle size during the operation. If the operator does not understand the thickness of the paint film, the technique is not proficient and it is easy to wear the paint layer, so it is only suitable for the highly skilled professional.

 

The main feature of the microcrystalline abrasive is that the microcrystalline particles can be gradually decomposed by the heat generated by the friction, and the volume thereof is gradually reduced during the operation, and the extremely high temperature is generated to remove the oxide layer, and the surface paint layer is dissolved. Partly fill the pinhole of the recess.

 

Neutral abrasive is the best lacquer care abrasive material on the market. It contains two kinds of cutting materials, clay and micro crystal. It is suitable for all kinds of automotive paints. It is easy to operate, fast, and has little grinding force. The cutting function has the function of chemical dissolution filling. The two materials are rubbed with the paint layer to generate heat, and the oxide layer is removed. At the same time, the lacquer layer bumps can be quickly dissolved and the recesses can be filled to achieve a double effect, so as to meet the polishing requirements. Substrate.

 

Mechanical grinding is the use of electric or pneumatic grinding machine instead of manual operation, grinding according to the principle of manual operation, generally requires the grinding machine to be easy to use, the rotation speed is generally higher, above 1800r / min, so the use should pay attention to prevent high heat generated by high speed And burn the paint film. The tools used for grinding are mainly grinding and polishing machines, which are generally classified into three types: single speed grinding machine, two speed grinding machine and multi speed grinding machine according to their speed.
