Common sanding and polishing technologies for automobiles

In order to prevent the appearance of the car from being damaged, many car owners sanded and polished the car by themselves, so that the appearance of the car can be neat and generous, and it can also prevent the car from rusting and bumping. Now, we will share with you 3 methods of sanding and polishing. The first is to hard remove the fine scratches by the force of sanding and friction material. The second is to rely on the effect of wax, after polishing to a certain extent, rely on the luster of wax to make up for the defects of polishing. The last one relies on chemical reaction, that is, the chemical reaction produced by the polishing agent by adjusting the rotation speed of the polishing machine.

The abrasive particles of physical sanding are choose different sanding disc and sandpaper sheet, with coarse, medium and fine grades, and the deoxidation and scratch effects are quite good, it is the mainstream sanding and polishing technology in the market; The finer abrasives are ground for more than two times, and the procedures are complicated.Physical and cover sanding need to wait for the rough and medium scratches that have just been polished to disappear, with a bright effect, but there are obvious fine scratches and optical rotation under sunlight. Reason is some scratches are filled by wax or resin oily components, not real Remove; the oiliness is too large, and the walking lines of the polished hairball will produce optical rotation. This polishing method is very easy to reproduce scratches after two or three car washes.

Delayed crushing and polishing technology is a relatively top and rare sanding technology. The abrasive is in the shape of glass beads, which will not cause secondary sanding scratches. At the same time, the temperature of the paint surface is low; when the polishing ball runs at high speed and the abrasive is generated At a certain temperature, the abrasive particles are instantly broken to form finer particles, which can effectively polish the fine and deep layers. One step in place, the more polished, the brighter. This polishing technology not only ensures the effect, but also minimizes the effect of polishing on the paint surface. Damage (polishing must hurt)! At the same time, this type of abrasive does not contain wax or resin oily ingredients, and the gloss thrown is the deep original gloss of the paint surface, and the cold light texture is amazing today.

How to choose a high-quality paint sanding product? First of all, minimize the damage to the paint surface while ensuring the complete removal of scratches and oxide layers. For example, depending on the specific conditions of the paint surface, it is reasonable to choose abrasives with fine particle size, and try to use sandpaper sheet locally, some manufacturers promote dry sanders to polish the paint surface for a mirror effect, which can increase the gloss. Secondly, you should not only pursue the surface effect after construction, and eliminate the use of products containing oily covering functions such as wax or resin. 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, improve the quality of the car, and prevent any accidents from happening to the car. The last method is to really produce a good mirror effect, that is, use the heat brought by the speed of the polishing machine to generate an energy, a chemical reaction between the car paint and the polish, to eliminate fine scratches and let the car paint show its body gloss, and then apply varnish to give the body a new look.
