Sanding And Polishing

1、Different concepts
Polishing, a surface modification technique, generally refers to a processing method that changes the physical properties of the material surface by friction with the help of rough objects (sandpaper containing higher hardness particles, etc.), the main purpose being to obtain a specific surface roughness.

Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method. Is the use of polishing tools and abrasive particles or other polishing media on the surface of the workpiece for finishing processing.

2, the nature of different

Polishing is to make the wall flat and smooth conducive to paint. Polishing is to flatten and make the wall shiny. That is to say, grinding is to make the surface of the object flat, polishing is to make the surface of the object shiny.

3、Different abrasives coarse and fine

The smaller the number, the finer the particle size, the larger the number the coarser it is, 8000# is the finest. Put jade grinding polishing, with coarse number grinding, fine number polishing after the jade is very bright. Polished glass, gemstones, jade, stainless steel, stone, can achieve a mirror effect. Polishing uses mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method.



Extended information.

Three kinds of mainstream grinding and polishing technology

1, the first is physical grinding

This kind of abrasive particles are irregular rhombus-shaped, coarse in fine level are available, to oxidation and scratches effect is quite good, is the mainstream of the market grinding and polishing technology; and with the angular coarse abrasive often cause secondary fine scratches, the need for a finer level of abrasive secondary above grinding, the procedure is complex, while inevitably hurt the paint surface. The frequent use of such abrasive products and techniques makes the paint surface like a drug dependent polishing and waxing, the clear coat layer has been thinner and thinner, and the original paint brightness is dulled.

2, the second is physical + cover grinding

Just polished coarse in the scratch disappeared, there is a bright effect, but in the sunlight there are obvious fine scratches and spin light, the reason: part of the scratch by the wax or resin oily ingredients to fill, rather than really remove; oil is too large, polishing hair ball walking lines produce spin light. This polishing method is very easy to wash two or three times after the car scratches reappear, has a strong deceptive.

3, the third is a relatively top and rare grinding technology

Delayed broken polishing technology, abrasive is glass bead round, will not cause secondary grinding scratches, while the temperature of the paint surface is low; when the polishing hair ball running at high speed and the abrasive produces a certain temperature, so that the grinding particles instantly broken, the formation of finer particles, effective on the fine deep polishing, a step in place, the more polished the brighter, this polishing technology is to ensure the effect, but also to maximize the elimination of polishing damage to the paint surface.

These abrasives do not contain waxes or resinous oil-based ingredients, so the lustre is the deep, original lustre of the lacquer, with a stunning cool texture.
