Aluminum Oxide 30 Or 40 Grit Manufacturers USA

Preparation of a-Al2O3 fine powder and ultrafine powder and white fused alumina ultrafine powder are also called fine powder and ultrafine powder. With its particle size as the criterion, a-Al2O3 fine powder with a particle size of not more than 90um is generally referred to as micropowder or ultrafine powder. The particle size limits of both aluminum oxide sandblasting media fine powder and ultrafine powder are not unified in various industries.

Many, its performance is significantly improved. The white aluminum oxide refractory industry at home and abroad generally uses 5um as the limit between the two, that is, powders not larger than 5um are called ultrafine powders; powders larger than 5um are called For fine powder. With the development of high and new technology, the development and utilization of corundum sand a-Al2O3 micropowder and ultrafine powder are highly valued at home and abroad.


Compared with relatively coarse materials, the specific surface area, surface atomic number, white corundum and surface energy of fine powders and ultrafine powders have all increased sharply, chemical reaction rates have increased significantly, and optical properties have changed significantly. When it is added to the ingredients, the firing temperature of the aluminum oxide for sand blaster product can be reduced, and the sintering time can be shortened.


Due to changes in the buildup, adsorption, rheology, and pink fused alumina melting properties of the mud, the strength and toughness, density, electrical properties, and magnetic properties of the product have changed significantly. A few equipment, such as jet air mill, can be used to produce materials smaller than 1um, which can crush the high purity fused aluminum oxide materials to the sub-micron level, the coarse powder does not lose the centrifugal force, that is, 0.1 ~ 0.5um.


In the special fused aluminium oxide refractory materials, high-purity sintered corundum bricks, irregular corundum refractory materials, especially refractory castables combined with dense high-strength clay and low-cement refractory castables, the application of micropowder and ultrafine powder is increasing. Some people call fine powder not more than 90um; aluminium oxide sandblasting fine powder not more than 5um; ultrafine powder less than 1um.


Another new development is the black aluminum oxide 70 grit abrasive media comprehensive use of suitable advanced mills and certain chemical preparation methods. The sedimentation method uses the mechanism of different particle size to settle in water. At present, there are two main types of methods for pink aluminium oxide producing a-Al2O3 fine powder and ultrafine powder, namely mechanical pulverization method and chemical synthesis method.


In fact, the chemical synthesis method is not a one-step chemical reaction. Often, high-purity aluminium oxide 36 grit is prepared by chemical method, and then appropriate grinding is performed to obtain high-purity a-Al2O3 fine powder and ultrafine powder. The centrifugal force is lost, and the person who is guided to the center of the pulverizer is ultrafine powder; black aluminum oxide abrasive 70 grit and continues to pulverize in the pulverizing belt.


The air inlet pressure and air circulation cycle time have a significant effect on the black aluminum oxide blast media particle size of the material, but the effect of the feed pressure is not significant. Japan has developed a high-efficiency pressure ball mill; Wuhan, China has developed a high-efficiency new type of ring seam mill, with an average particle size of less than 5um for grinding black synthetic corundum micropowder and low energy consumption.
