WA Valkoinen korundihiekka

WA valkoinen korundihiekka on valmistettu alumiinioksidijauheesta raaka-aineena, joka kiteytetään elektrolyysillä. Sen kovuus on hieman korkeampi kuin ruskean korundin, hieman alhaisempi sitkeys, korkea puhtaus, vahva jauhatusvoima, alhainen lämpöteho, korkea hyötysuhde, happo- ja alkalikorroosionkestävyys ja hyvä. WA valkoinen korundihiekka on puhdasta valkoista jauhetta, rakeistaKorkean lämpötilan kestävyyttä ja lämmönkestävyyttä.

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.
