Abrasive blasting range of applications

( A ) coating the workpiece , the workpiece can blasting treatment before bonding the surface of all dirt or rust removed and the surface of the workpiece is important to establish the basis of the drawings ( which is usually called the matte side ) , and can be through the exchange of different size abrasive , abrasives such as abrasive Chin achieve varying degrees of roughness , greatly improving the work with paint, coating material adhesion. Or so pieces of adhesive bonding stronger , better quality .
(B ) casting matte , sandblasted after heat cleaning and polishing the workpiece can clean up the castings and forgings , all the dirt surface after heat treatment (eg, oxide , oil, and other residues ) , and to improve the surface finish of the workpiece polishing can make mold for grinding wheel workpieces exposed metal color uniform , so that the workpiece looks more beautiful, beautiful.
(C ) machined parts deburring and surface blasting can clean up the surface to beautify the tiny glitches, and make the surface more smooth , eliminating the hazards glitches and improve the quality of the workpiece. And sandblasting can play a small fillet at the junction of the workpiece surface , the workpiece is even more beautiful, more sophisticated .
(D ) to improve the mechanical properties of the parts after sandblasting machine parts , can produce a uniform fine uneven surface in parts of the surface , so that oil get stored , so that lubrication conditions improve and reduce the noise to improve the mechanical life.
(E ) light decoration effect for some special purpose parts, sandblasting can easily implement different reflective or matte . Such as stainless steel parts , plastic grinding , polishing , wooden furniture matt surface of jade , patterns frosted glass surface and texturing surfaces such as fabrics .

Diamond Case

Yuan Shi
December 2010, Japanese scientists
Cylindrical "Yuan Shi"
Successfully synthesized the world's cubic boron nitride hardest diamond, more than 1 cm in diameter, and strive to cooperate with the fastest production company said.
This is the result of a cylindrical diamond Ehime University researchers in Japan with Sumitomo Electric Industries, Inc. cooperation, was named "Yuan Shi", taken from "Ehime."
Tetsuo researchers into the boat, said Yuan stone is the world's hardest artificial diamond, diamond-hard, a lot more than ordinary, and therefore can be applied to many industrial activities were. "Yuan Shi can help people learn more about carbon elemental crystals under high pressure and temperature conditions deep in the earth formation; same time, as a kind of industrial supplies, its life expectancy is several times longer than ordinary diamond.

White corundum

White fused aluminum oxide powder is a high-quality raw materials, smelting by fused it with white color, high hardness, toughness slightly lower, high purity, excellent self-sharpening, grinding power, low heat, high efficiency , acid corrosion, high temperature resistance, good White fused aluminum oxide thermal stability and other characteristics, it is not only superior abrasive materials, and or advanced grinding, polishing materials, processed with abrasive it made ??for grinding carbon steel, high speed steel and a variety of stainless steel. It is also widely used in precision casting, steel sandblasting material fire-resistant, fire-resistant chemicals, 95 porcelain, decorative ceramics and porcelain, and other special daily use porcelain, as well as military, electronics and other high-tech industries.

Fused zirconia corundum brick

Fused zirconia corundum brick AZS fused zirconia corundum brick , also known as the abbreviation is AZS, is based on three chemical composition Al2O3-Zr02-Sio2 ternary phase diagram , according to their order of how much content , Al2O3 take A, Zr02 take Z, Sio2 take S, using the abbreviation green silicon carbide for national standards , such as 33 cast AZS bricks, abbreviated as AZS-33 #, 36 cast AZS bricks, abbreviated as AZS-36 #, 41 cast AZS bricks, abbreviated as AZS-41 #.
AZS bricks are fused with pure alumina and zirconia powder 65% , about 34% silica, zircon sand in the melting furnace in the power injected into the model of cooling a white solid formed , which facies helical structure of corundum and zircon stone and glass eutectoid phase composition , in terms of learning from the phase -phase and zirconium corundum stone ramp eutectoid phase , filling the glass with crystal between them .

Black silicon carbide Introduction

Silicon carbide is divided into black and green silicon carbide. Silicon carbide, also known as Moissanite. In The use of steel fibers contemporary C, N, B and other non-oxide refractory materials in high-tech, silicon carbide is the most widely used and most economical one. Can be called emery or refractory sand. Where: Black silicon carbide is quartz sand, petroleum coke and quality silica as the main raw material, smelting electric arc furnace. Its hardness between corundum and diamond, corundum higher Fused zirconia mullite mechanical strength, brittle and sharp. Silicon carbide, metallic luster, containing more than SiC 95%, greater than the intensity of green silicon carbide, but lower hardness, is mainly used for grinding cast iron and non-metallic materials
