Kusiyana pakati pa gudumu lopera la brown corundum ndi gudumu lopera loyera la corundum

1. Zopangira: Zopangira za brown corundum ndi anthracite, filings zachitsulo ndi bauxite.Zopangira za white corundum ndi alumina ufa.

2. Mtundu: white corundum imakhala ndi aluminiyamu yapamwamba kwambiri kuposa brown corundum, choncho white corundum abrasive ndi yoyera, pamene abrasive corundum a bulauni ndi bulauni wakuda.

3. Zina mwazinthu: corundum ya bulauni ndi yoyera imakhala ndi aluminiyamu, koma alumina ya white corundum ndi yoposa 99, ndipo zomwe zili mu brown corundum zimakhala pafupifupi 95.

4. Kuuma: kuuma kwa corundum koyera ndikwapamwamba pang'ono kusiyana ndi korundum ya bulauni.White corundum abrasive ndi crystalline pawiri yokhala ndi kuuma kwabwino komanso kulimba, kukula kwa kristalo wabwino komanso kukana kuvala bwino, koma mtengo wopangira ndi wokwera ndipo zotulutsa zake ndizochepa.Brown corundum abrasive imakhala ndi kuuma kwapakatikati, kufooka kocheperako komanso mtengo wotsika.

5. Magwiridwe: Brown corundum ali ndi makhalidwe a chiyero chapamwamba, crystallinity wabwino, fluidity amphamvu, otsika liniya kukulitsa coefficient ndi kukana dzimbiri.White Corundum ili ndi mawonekedwe a chiyero chapamwamba, kudzipukuta bwino, kukana kwa asidi ndi alkali corrosion, kukana kutentha kwambiri komanso kukhazikika kwamafuta.Mosiyana ndi zimenezi, kuuma kwa white corundum ndikwapamwamba kuposa kofiira kofiira.
