Hardware knowledge: China's three mainstream grinding and polishing technology

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 kind of physical grinding, the abrasive particles are in irregular diamond shape, the thickness is fine, the deoxidation scratch effect is quite good, the market mainstream grinding and polishing technology; and the angular coarse abrasive often causes secondary fine scratches. It requires a finer level of abrasive for more than two times of grinding, the procedure is complicated, and it is inevitable to damage the paint surface. This abrasive product technology is 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 original car paint brightness is eclipsed.

 

 

 

2, the second physical + cover grinding; just after the thick scratches disappear, there is a bright effect, but there are obvious slight scratches under the sunlight, the reason: some scratches are filled with wax or resin oily ingredients, not real Remove; oily too large, polished hair ball walking lines produce optical rotation. This kind of polishing method is very easy to wash after two or three times, and the scratches are reappeared, which is highly deceptive. I don't know if the shopkeeper technician will be very upset!

 

 

 

3, the third comparison of rare top grinding technology: time-lapse crushing and polishing technology, the abrasive is round bead, will not cause secondary grinding scratches, while the paint surface temperature is lower; when the polishing ball is running at high speed and abrasive When a certain temperature is generated, 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 polishing damage to the paint surface is minimized ( Polishing must be harmful)! At the same time, this type of abrasive does not contain wax or resin oily ingredients, throwing a glossy lacquer finish deep enamel gloss, 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 layers are completely removed, and the damage to the paint surface is minimized. For example, depending on the specific conditions of the paint surface, the grain thickness abrasive should be used reasonably, and the sandpaper should be used as much as possible. (There is a manufacturer to promote the dry grinder to polish the paint surface to make the mirror effect. Personally, it is meaningless to protect the paint surface for a long time, but it can increase the gloss and kill the chicken. Suspected)

 

 

 

2, should not only pursue the surface effect after construction, to prevent the use of oily cover products such as wax or resin.
