Several abrasives for coated abrasive products

1, brown aluminium oxide:

The main chemical component, AL2O3, is made from bauxite, iron filings and anthracite in an electric arc furnace. The color of the brown alumina oxide abrasive is brown, and in terms of its color, it is named brown alumina oxide. This kind of abrasive has a certain hardness and toughness, has a strong grinding ability, and can withstand a lot of pressure. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance and good chemical stability. Due to its high tensile strength, it is suitable for grinding materials with high tensile strength. It is suitable for ordinary steel, high carbon steel and alloy steel. It can be used for the processing of hard wood. It can also be used for the replacement of other abrasives. Abrasive is the most widely used abrasive in use.

3. Black silicon carbide:

The main chemical composition is SiC. It is made of petroleum coke, quartz sand, wood chips and the like as raw materials in an electric resistance furnace. Black SiC has a black color and is named black silicon carbide in terms of its color. Black silicon carbide is more brittle than corundum, harder than hardness, and its toughness is second to that of corundum. For materials with low tensile strength, such as non-metallic materials (various plates such as wood plywood, particleboard, high-middle and low-density fiberboard). , bamboo board, calcium silicate board, leather, glass, ceramics, stone, etc.) and non-ferrous metals (aluminum, copper, lead, etc.) and other materials are particularly suitable for processing, and the processing of hard and brittle materials is also an ideal abrasive. .

 Zirconium aluminium oxide abrasive:

It is a high toughness abrasive with ZrO2 and a 20 micron crystal size. ZrO2 is added in 40% and 25%. It is used for coating abrasives with sharper shapes. It is especially suitable for processing stainless steel parts and titanium alloy parts. In the Chinese market, Japan's NCA's  Zirconium aluminium oxide abrasive belt, NORTON's NORZON belt of the United States and South Korea's Korean grinding company's YZ533 and YZ633 zirconium corundum belts are more popular. According to the information provided by NOTON Company of the United States, the grinding efficiency is 254-300% higher than that of brown corundum. The processing of particleboard with NORZON abrasive belt increases the life of the belt by three times.

However, the zirconium corundum belt is not only used as abrasive belt but also used in a large number of fixed abrasives.
