Analysis of mainstream grinding and polishing technology in China

There are many kinds of grinding and polishing products on the market in China. From the technical principle, we mainly divide into three types:

 

 

 

1. The first type is physical grinding. The abrasive particles are irregularly shaped in the shape of diamonds. They are coarse and medium-grade. The deoxidation and scratching effects are quite good. They are the mainstream grinding and polishing technology in the market; Causes secondary fine scratches, requires a finer level of abrasive for more than two times of grinding, the program is complicated, and inevitably hurts the paint surface. This kind of grinding products and technology are often used to make the paint surface rely on polishing and waxing like drug use. The varnish layer has been thinner and thinner, and the brightness of the original car paint is eclipsed.

 

 

 

2, the second is physical + cover grinding; freshly scratched after the disappearance of the rough, there is a bright effect, but there are obvious slight scratches and optical rotation under the sun, the reason: some scratches are wax or resin oily ingredients Fill, not really remove; oily too much, polished hair ball walking lines produce optical rotation. This kind of polishing method is easy to reproduce after scratching two or three cars, and it is highly deceptive. I don't know why the owner and technician will be very upset!

 

 

 

3, the third is the more advanced and rare grinding technology: time-lapse crushing and polishing technology, the abrasive is round bead, will not cause secondary grinding scratches, while the temperature of the paint surface is lower; when polishing the ball high speed When the operation and the abrasive generate a certain temperature, the abrasive particles are instantaneously broken to form finer particles, which are effective for fine deep polishing, one step in place, and the more polished, the polishing technology ensures the effect, and the maximum elimination is eliminated. Polishing damage to the paint surface! At the same time, this kind of abrasive does not contain wax or resin oily ingredients, and the shiny luster is the lacquer gloss of the lacquer surface. The cold light texture is amazing now.

 

 

 

How to choose high quality paint grinding products, we have two suggestions:

 

 

 

1. Minimize damage to the paint surface while ensuring complete removal of scratches and oxide layers. For example, depending on the specific conditions of the paint surface, the abrasive of the particle size should be used reasonably, and the sandpaper should be used as much as possible.

 

 

 

2. It is not only necessary to pursue the surface effect after construction, and to prevent the use of products containing oily covering functions such as wax or resin.
