.White Corundum White corundum is made from high-quality aluminum oxide powder as raw material through electrofusion refining and crystallization. It has high purity, good self-sharpening properties, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It has strong grinding ability, low heat generation and high efficiency. It can be used to make abrasive tools, which are suitable for grinding fine-grained abrasives such as high-carbon steel, high-speed steel and stainless steel, and can also be used for precision casting and advanced refractory materials.
.White corundum sandblasting performance and advantages

White corundum micro powder specifications.-Material
This product It is suitable for ultra-precision grinding of polishing machine tool spindles of various precision instrument parts, crystal grinding and polishing, super-essential oil stone manufacturing, steel ball polishing, etc. Widely used in grinding and polishing electronics, optical instruments, glasses, bearings, quartz crystals, advanced refractory materials, etc.
Detailed description:
. High hardness, dense particles, and good roundness of single particles.
.The color is pure white without impurities, ensuring the color and transparency of the wear-resistant layer or wear-resistant paper.
.The particle size distribution is uniform and the single particles are concentrated and uniform in shape. The minimum amount can achieve the maximum wear-resistant effect.
.It is carefully made from selected high-quality white corundum that has been smelted at a high temperature of more than 2,000 degrees. It has stable chemical properties and does not interact with acids and alkali. It has minimal heat shrinkage.
White corundum particle size - (mesh) applicable scope sandblasting/polishing/grinding
White corundum is suitable for surface beautification of various high-end product processes or hardware and other products. After sandblasting, the surface will be white without any impurities, eliminating the need for cleaning. trouble. Fine white corundum can be used as a polishing tool. It can also be used as a variety of product additives.
Sandblasting machine functions:
Surface processing: metal oxide layer, carbide, black skin, metal or non-metal surface rust removal, such as gravity die-casting mold, rubber mold oxide or release agent removal, ceramic surface black Point uranium color removal paint rebirth.
, Beautification processing: Matte or matte processing of various gold, gold, precious metal products, crystal glass, corrugated acrylic and other non-metallic matte processing, and can make the surface of the processed object into a metallic luster.
, etching processing: etching art for jade, crystal, agate, semi-precious stones, seals, elegant stones, antique marble tombstones, ceramics, wood, bamboo slices, etc.
. Pre-treatment: Teflon (), rubber plastic coating, rubber roller (r), electroplating, metal spray welding, titanium plating and other pre-treatments to increase surface adhesion.
, Burr processing: Burr removal of bakelite, plastic, zinc and aluminum die-casting products, electronic parts, magnetic cores, etc.
. Stress relief processing: Stress relief processing for rust removal, paint removal, matting and renovation of parts in the aerospace and defense precision industries.
Electronic parts processing: remove the matte surface of silicon chips and impurities on the back of etched wafers, remove glue overflow from electronic parts packaging, remove printing on the surface of finished products, and clean ceramic electric heating.
Mold processing: Generally, the surface of the mold is sandblasted and then matte treated. Line cutting mold. Glass mold. Tire mold. Conductive rubber mold. Shoe mold. Bakelite mold. Electroplating mold. Button molding. Plastic product mold.
. Processing of large workpieces: rust removal and paint repair of large workpieces such as oil tanks, chemical tanks, ship hulls, copper structures, iron sheets, containers, automobile industries, etc., and automatic matte treatment of large flat glass.
, Glass processing: Sandblasting of various glass crafts.
