WA Baltasis korundo smėlis

WA baltas korundo smėlis yra pagamintas iš aliuminio oksido miltelių kaip žaliavos, kuris kristalizuojamas elektrolizės būdu. Jo kietumas yra šiek tiek didesnis nei rudojo korundo, šiek tiek mažesnis kietumas, didelis grynumas, stipri šlifavimo jėga, maža šiluminė galia, didelis efektyvumas, atsparumas rūgščių ir šarmų korozijai ir geras. WA baltas korundo smėlis yra gryni balti milteliai, granuliuoti, atsparūs aukštai temperatūrai ir karščiui atsparūs.

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.
