Common grinding and polishing methods for cars
2022-10-13
In order to prevent the appearance of the car from being damaged, many car owners grind and polish the car. This will make the appearance of the car tidy and generous, and also prevent the car from rusting, bumping, and so on. How much do you know about the polishing machine?
Grinding and polishing method:
1. Physical grinding
This kind of abrasive particles has an irregular diamond shape and has coarse, medium and fine grades. The effect of deoxidation and scratches is quite good. It is the mainstream grinding and polishing technology on the market; but coarse abrasives with corners often cause secondary fine scratches, which require more The finer grade abrasives will grind more than two times, the procedure is complicated, and the paint surface will inevitably be damaged at the same time. Frequent use of this kind of abrasive products and technology makes the paint reliant on polishing and waxing like drugs. The varnish layer has become thinner and thinner, and the brightness of the original car paint has been eclipsed.
2. Physics + Cover Grinding
The rough scratches that have just been thrown disappear, and there is a bright effect, but there are obvious slight scratches and rotation in the sun. The reason: part of the scratches are filled by wax or resin oily ingredients, rather than really removed; too oily, The walking pattern of the polished hair ball produces light rotation. This polishing method is easy to reproduce the scratches after washing the car two or three times.
3. Delayed crushing and polishing technology
Delayed crushing and polishing technology is a relatively top and rare grinding technology. The abrasive is in the shape of glass beads, which will not cause secondary grinding scratches. At the same time, the temperature of the paint surface is lower; when the polishing ball runs at high speed and the abrasive is produced At a certain temperature, the abrasive particles are instantly broken to form finer particles, which can effectively polish the fine and deep layers. It can be achieved in one step, and the more polished, the brighter. This polishing technology guarantees the effect and minimizes the effect of polishing on the paint surface. harm. At the same time, this kind of abrasive does not contain wax or resin oily ingredients, and the gloss it throws is the deep original luster of the paint surface, and the cold light texture is amazing today.
The principle of polishing:
1. Cutting; through the continuous friction of the polishing disk at the speed of the polishing machine, the periphery of the scratch is gradually thinned and the thickness of the scratch is gradually matched.
2. Paint surface fusion; through polishing and grinding, the temperature of the paint surface rises, the car paint becomes soft, and the paint surface of the unevenness is merged.
1. Under the condition of ensuring the complete removal of scratches and oxide layers, minimize the damage to the paint surface. For example, depending on the specific situation of the paint surface, choose an abrasive with a reasonable particle thickness and use sandpaper as much as possible. Suspected of killing chickens and getting eggs)
2. The surface effect after construction should not only be pursued, and the use of products containing oily covering functions such as wax or resin should not be used. If you plan to polish your car, you must choose the method that best suits your car. Don't be greedy for cheap. Choose some regular repair shops for maintenance to improve the car's compelling standard and prevent any accidents.
The first two methods are often used by beginners. The main reason is that beginners have insufficient understanding of the relationship between the speed of the polishing machine, the material of the polishing head (full wool material, blended material, sponge material and cotton material, etc.), the structure of the lacquer, and the effect of the polishing agent. Insufficient, so the requirements for polishing are not high. Because it doesn't matter if it is not too shiny, it will be very shiny after applying wax. But this light is phantom light. It cannot achieve the final mirror effect, and the gloss has no depth. And its retention time is very short, because its luster does not come from lacquer, but wax; no matter how good the wax, at best, it can only "gloss" for two to three months. The light of the wax is gone, and the light of the car paint is gone.

Therefore, the third method that can really produce a good mirror effect is to use the heat brought by the speed of the polisher to generate an energy and a chemical reaction between the car paint and the polishing agent to eliminate fine scratches and make the car The lacquer shows the luster of its body, and then polishes wax is applied to make the car icing on the cake.
