Comparison Of The Advantages Of Dry Grinding And Water Grinding in Automobile Painting

In the painting process, the grinding process of the repaired car body surface is very important. If it is not handled properly, the painted surface will feel rough and uneven, which will seriously affect the painting effect, and sometimes it needs to be repaired, which is time-consuming and laborious. 
wet grinding
Time-consuming and labor-intensive Quality unstable
If the previous step is manually polished with water and water sandpaper, it will require a large amount of labor, and the quality of grinding is determined by the worker's operating experience and technical level, and the quality varies. When using atomic ash to fill the car surface in the later stage, water grinding is likely to cause technical problems such as layer peeling and paint blistering. the
dry grinding
Save process pollution
Dust-free dry grinding uses pneumatic or electric tools. While grinding, the integrated vacuum system is used to suck the dust into the dust bag of the dust bucket and collect it uniformly. The advantage of dry sanding is that machine sanding is used, and the paint surface treatment effect is better than that of manual sanding. The dry grinding process does not require water, and there is no need to worry about the influence of water on the surface of the car paint and the metal on the car surface. the
water mill problem
1. Two-component refinish paint products are very hard and difficult to polish, and manual polishing is labor-intensive, labor-intensive, and time-consuming.
2. Two-component touch-up paint products, especially putty, have a certain degree of water absorption. After water grinding, the newly sprayed paint surface is prone to water rash and blisters, which will affect the adhesion of the paint surface. the
3. After the metal part of the body shell comes into contact with water, it is easy to rust. the
4. The sewage in the workshop pollutes the environment, is not conducive to safe production, and affects the corporate image.
5. Long-term contact with car paint and water is not conducive to the health of painters
Advantages of dry grinding
1. Shorten the polishing process and time, and reduce the labor intensity of the painter
2. Reduce the program time for repairing the surface of the car body, omit multiple drying times, simplify the repair process, and ensure the quality of the painting. the
3. Reduce the number of reworks caused by unstable painting quality, bid farewell to sewage, save water, and protect the health of employees
Manual water grinding can polish about 1 square meter per hour, and mechanical dry grinding can polish 10 square meters per hour. The speed has been improved a lot. Dust-free dry grinding has improved the working environment of workers and reduced the impact of dust on the body. Now 4S shops and Almost all maintenance points use dry grinding technology. Car owners must be optimistic before choosing a maintenance business during the process of vehicle maintenance.
