WA Baltās korunda smiltis

WA baltās korunda smiltis ir izgatavotas no alumīnija oksīda pulvera kā izejmateriāla, kas tiek kristalizēts ar elektrolīzi. Tā cietība ir nedaudz augstāka nekā brūnajam korundam, ar nedaudz zemāku stingrību, augstu tīrības pakāpi, spēcīgu slīpēšanas spēku, zemu siltuma jaudu, augstu efektivitāti, izturību pret skābju un sārmu koroziju un labu. WA baltā korunda smiltis ir tīrs balts pulveris, granulētsAugstas temperatūras izturība un siltuma stabilitāte.

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.
