WA ホワイトコランダムサンド

WAホワイトコランダムサンドは、酸化アルミニウム粉末を原料とし、電気分解により結晶化させたものです。 硬度は褐色のコランダムよりわずかに高く、靭性はわずかに低く、高純度、強力な研削力、低熱出力、高効率、酸およびアルカリの耐食性が良好です。 WAホワイトコランダムサンドは、純白の粉末、粒状であり、高温耐性と熱安定性を備えています。

WA white corundum sand is made of aluminum oxide powder as raw material, which is crystallized by electromelting. Its hardness is slightly higher than that of brown corundum, its toughness is slightly lower, its purity is high, its self-sharpness is good, its grinding ability is strong, its caloric value is small, its efficiency is high, it is resistant to acid and alkali corrosion, high temperature resistance, and its thermal stability is good. It is made of abrasive tools, suitable for grinding high carbon steel, high speed steel and so on. It can also be used as grinding, polishing materials, precision casting, spraying materials, chemical catalyst carriers, special ceramics, refractory materials and so on.WA white corundum sand physical and chemical indicators: use specificationsMain chemical composition A1203,Na20%Si02 magnetic material %Ca0 abrasivesF12#-80#>99.00.0030.50.490 # - 150 # > 98.50.60.003180 # - 240 # > 98.20.70.40.002 W1#-63#>97.50.81.00.50.001 Refractory.
