Description
| 1.Production description White aluminum oxide (or white aluminium oxide ) abrasive is a 99.5% ultra pure grade of blasting media. White aluminum oxide is increasingly being used in critical, high-performance microdermabrasion equipment. The purity of this media along with the variety of grit sizes available make it ideal for both traditional microdermabrasion processes as well as high-quality exfoliating creams. White aluminum oxide abrasive is an extremely sharp, long-lasting blasting abrasive that can be recycled many times after the initial media blasting. It is the most widely used abrasive in blast finishing and surface preparation because of its cost, longevity and hardness. Harder than other commonly used blasting materials, white aluminum oxide grains penetrate and cut even the hardest metals and sintered carbide. Approximately 50% lighter than metallic media, white aluminum oxide has twice as many particles per pound. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower-cutting media blasting grits. White aluminum oxide blasting media has a wide variety of applications, including cleaning engine heads, valves, pistons and turbine blades in the aircraft and automotive industries. White aluminum oxide is also an excellent choice for preparing a hard surface for painting. White aluminum oxide contains less than 0.2% free silica and is therefore safer to use than sand. The grit size is consistent and cuts much faster than other sand blasting media, leaving a smoother surface. 2.Chemical and physical parameters AI2O3 CONTENT= 99.00 % SiO2 CONTENT = 0.04 % Na2O CONTENT = 0.30% Fe2O3 CONTENT =0.04% Item Property Bulk density 1.75-1.95g/cm3 Grain density 3.97g/cm3 Morse hardness 9 Melting point 2250 Degrees Celsius Refractoriness 1850 Degrees Celsius |
