Product Description

Use of white rigid jade sand:
Grinding: mainly free grinding, glass, jade products, these materials can be ground with white corundum, can also be used ceramic, precision workpiece grinding, abrasive is mainly used for grinding white corundum, brown corundum, black corundum, silicon carbide, iron sand, copper ore.

Grinding tools: used in the production of resin grinding machine, coating grinding tools, these words have made a certain summary, that is, white corundum and brown corundum can produce sandpaper sandwheel gauze, etc.

Sand blasting rust removal: stainless steel, iron parts, copper workpiece can be sandblasted with white corundum, because white corundum abrasive can purify, deoxygenation skin, increase coating, interlayer adhesion, can also be used for plastic products and glass products, as well as denim sandblasting operations.

Filler: use the most floor materials, can be used for factory sites, sports ground, runway, parking lot and other places. Actually, because of the higher price of white corundum, black and inferior brown corundum are usually used as abrasive floor materials.

Water knife cutting: mainly rely on high pressure hydraulic jet, used for cutting pipe and steel.

The uses of white sand also include:
Metalworking: the white corundum sand is often used for the grinding and polishing of the metal surface. Due to the high hardness of white corundum sand, it can effectively remove the oxide layer, rust and stains on the metal surface, and restore the finish and brightness of the metal surface.

Stone cutting: white rigid jade sand also plays an important role in stone cutting. Due to the high hardness of the stone, the general grinding wheel is difficult to cut, and the use of white rigid jade sand cutting tools can easily complete the stone cutting task.

Ceramic manufacturing: in the ceramic manufacturing process, white rigid jade sand is used as an abrasive for ceramic materials. The surface finish and flatness of ceramic products have an important influence on their quality and aesthetics. White rigid jade sand can polish the surface of ceramic materials, remove the uneven and burr of the surface, and make the surface of ceramic products more smooth and delicate.

Electronics industry: white rigid jade sand is also widely used in the electronics industry. In the semiconductor manufacturing process, the white rigid jade sand is often used for the polishing and leveling of thin films. It can remove the inhomogeneity and defects on the film surface and improve the optical and electrical properties of the film.

Glass manufacturing: white corundum sand also plays an important role in the glass manufacturing process. During the surface polishing and repair process of glass, white rigid jade sand can remove scratches and defects on the surface, making the glass surface more smooth and transparent.
In conclusion, white corundum sand is widely used in many industrial fields due to its unique physical and chemical properties.
