Derusting Sand

Author:Jinlin corundumTo update: 2016-10-18

In the life, many items will be in contact with water or because of the place in a cool and humid place will rust, we tend to worry about this, in order to solve your troubles, our company produces the derusting sand can be very good to achieve the effect of rust.
I. An overview of derusting sand
Corrosion-resistant sand is the general term for abrasive abrasive. Fused alumina sand, black fused alumina, silicon carbide, copper ore and so on are commonly used for removing rust. It has strong rust-removing ability and is the first choice for industrial-grade rust removal.
II. The characteristics of derusting sand
According to what is abrasive, we know that the abrasive contains the product, derusting sand is a general term for  abrasive, so derusting sand with all the characteristics of abrasive products.
The derusting sand has the characteristics of moderate hardness, high toughness, good self-sharpening, low sand consumption and recyclable use, good abrasion resistance, stable chemical composition, abrasion resistance and acid and alkali resistance.
Derusted sand abrasive shell-like fracture, sharp corners, in the crushing classification in the formation of new edges and edges, so that the grinding ability is better than other abrasives. Especially its high hardness, specific gravity, chemical stability and its unique advantages of self-sharpening, so it is known as the preferred technology for abrasive, but also clean the workpiece rust, grinding rust ideal material.
III. The advantages of derusted sand
1. Smooth surface, injection speed;
2. Its unique internal needle-like structure can quickly achieve the effect of rust, rust high efficiency;
3. No dust pollution during blasting, clear vision;
4. After sand blasting, sandblasted surface clean, no dust attached;
5. Sand blasting the surface of small particles mosaic phenomenon;
6.Blasting the surface even formation, no copper ore after the burr phenomenon;
7. The reusability of 4-5 times.

IV. The use of derusted sand
As the derusting sand contains black fused alumina, copper ore, silicon carbide and other products, so the use of black fused alumina, silicon carbide, the main application should be equipped with derust.
1. Stainless steel surface decontamination, in addition to welding slag and matte effect;
2. Iron workpiece to rust, decontamination, in addition to oxide skin;
3. The aluminum workpiece to oxide skin, surface strengthening, decorative effect;
4. Copper workpiece to oxide skin matte effect;
5. Crystal glass frosted, engraved pattern;
6. The matte effect of plastic products;
7. Denim and other special fabrics, plush processing and effect patterns;
8. Automobile factories, shipyards, such as polishing the surface rust.
V. Derust and sand of the physical and chemical indicators
Chemical indicators of derusting sand:
Al2O3: ≥99.5%
Fe2O3:? 0.4%
Na2O:? 0.22%
SiO2:? 0.04%
Physical indicators of derusting sand:
Knoop hardness: 2000-2200Kg / mm2
Mohs hardness: 9
Bulk density: 1.75-1.95 g / cm3
True density: 3.9-4.9 g / cm3
