100 Grit Aluminum Oxide White Manufacturers In NZ

White corundum is made from industrial alumina powder, smelted in an electric arc at a temperature of more than 2000 degrees, and then cooled. It is crushed and shaped, iron is removed by magnetic separation, and sieved into a variety of particle sizes. Its texture is dense, high hardness, and the particles form sharp angles. The bulk density of the 150 grit aluminum oxide is greater than a single particle size density.

Shape, suitable for the manufacture of ceramics, resin-consolidated abrasives, grinding, polishing, black corundum sandblasting, precision casting (corundum for precision casting), etc., and also for the manufacture of advanced refractory materials. There are two types of white corundum density, one is the density of white corundum, and the other is the true density of white corundum. Sub-white corundum is produced on the basis of high-quality black silicon carbide.

The bulk density is 1.53--1.99g / cm3. The bulk density of the white fused alumina abrasive is related to the particle size, particle size composition, variety, particle shape and other factors of the abrasive. Generally, coarse-grained abrasives have higher bulk density and finer-grained abrasives than fine-grained aluminum oxide abrasive. The particle density is 3.95 ~ 4.0g / cm3. In recent years, the true density of corundum for precision casting has reached 4.1g / cm3.

The true density of the abrasive refers to the mass of the pink corundum contained in a unit volume (excluding the volume with open pores). The basic particle size is: 45% -55%. The basic particle size is an important indicator to ensure the grinding effect. It should be properly controlled during production. But production may slow. The synthetic corundum purpose of pickling and water washing is to remove iron impurities in the abrasive. Sorting is carried out in glass tanks by water separation.

white aluminum oxide is made from alumina powder and smelted at high temperature. After drying, use a glass pestle or horn spoon to grind the cake. The grinding force gradually increases with the increase of the dressing amount, and then tends to stabilize the sand inlay grinding and All abrasives used in fine polishing need to be processed. aluminum oxide grit is based on bauxite and coke (anthracite) as the main raw materials. 

Put silicon carbide abrasive grinding powder in electric furnace or muffle furnace, and raise it from normal temperature to 850 degrees. For W0.5-w1 grinding powder, it can sometimes reach 1200 degrees, and then keep it for 5 hours. Using white corundum rollers to dress and braze emery abrasive, the radial runout of the grinding wheel is significantly reduced, and the surface roughness of the ground workpiece is significantly reduced.

It is smelted in an electric arc furnace at a high temperature of 2000 degrees. The main brown fused alumina price chemical composition is Al2O3, TiO2, containing a small amount of SiO2 and Fe2O3, etc., and its microhardness is HV1800-2200. , Toughness is higher than SiC. The abrasives made with it are suitable for grinding high tensile metals, such as various general steels, malleable cast iron, hard bronze, etc., and artificial corundum can also manufacture advanced refractory materials.

The green silicon carbide temperature is increased by 10 ° C (20 ° C) in a baking oven. It is white with slightly higher hardness and slightly lower toughness than aluminum oxide blasting abrasive. The abrasive tool produced by it is suitable for the grinding of high carbon steel, high speed steel and quenched steel. It can also grind and polish materials, and can also be used as precision casting sand, spraying materials, chemical catalysts, special ceramics, and advanced refractory materials.
