Three mainstream grinding and polishing technologies in my country

There are many types of grinding and polishing products on the market in our country. From the technical principle, we temporarily divide them into three types:

1. The first type of physical grinding. This kind of grinding particles is irregular rhombus shape, with both thickness and level. The effect of deoxidizing scratches is quite good. The mainstream grinding and polishing technology in the market; and rough abrasives with edges and corners often cause secondary For fine scratches, a finer one-level abrasive is required to grind more than two times, the procedure is complicated, and the paint is inevitably damaged. This kind of abrasive product technology is often used to make the paint surface dependent 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. The second type of physics + cover grinding; the rough scratches disappeared after polishing, and there is a bright effect, but there are obvious slight scratches under the sun. The reason: some of the scratches are filled by wax or resin oily ingredients. It is not really removed; the oiliness is too large, and the walking texture of the polished hair ball will produce light rotation. This polishing method is very easy to reproduce the scratches after washing two or three times, and it is quite deceptive. It will be very annoying if you don’t know how to deal with the shopkeeper’s technician!

3. The third kind of relatively top rare grinding technology: delay crushing and polishing technology, the abrasive is round glass beads, which will not cause secondary grinding scratches, and the paint surface temperature is lower; when the polishing ball runs at high speed When a certain temperature is generated with the abrasive, the abrasive particles are instantly broken to form finer particles, which can effectively polish the fine and deep layers. One step is in place, the more polished, the brighter. This polishing technology guarantees the effect and eliminates the effect of polishing to the utmost. Face damage (polishing must cause damage)! At the same time, this kind of abrasive does not contain wax or resin oily ingredients, and it throws out the deep luster of the luster paint surface, and the cold light texture is amazing today.

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

1. Ensure that the scratches and oxide layer are completely removed, and the damage to the paint surface is minimized. For example, depending on the specific situation of the paint surface, choose the coarse and fine abrasive particles reasonably, and use sandpaper as much as possible. (Some manufacturers promote dry grinders to polish the paint surface to make the mirror effect. I personally think that long-term protection from the paint surface is meaningless, but it can increase the gloss. Suspect)

2. The surface effect after construction should not be pursued only, and the use of oily covering products containing wax or resin should not be used.
