Aluminiyamu wosakanikirana woyerandi aluminiyamu wophatikizika wa bulauni ndi ma abrasives awiri omwe amagwiritsidwa ntchito kwambiri.Anthu ambiri sadziwa kusiyana kwachindunji pakati pa ziwirizi kupatula mtundu.Tsopano ndikutengerani kuti mumvetse.
Ngakhale ma abrasives onse ali ndi aluminiyamu, aluminiyamu yoyera yosakanikirana ndi aluminiyamu yoyera ndi yoposa 99%, ndipo aluminiyamu ya aluminiyamu yophatikizika ya bulauni imaposa 95%.
Aluminiyamu wosakanikirana woyeraamapangidwa kuchokera ku ufa wa alumina, pomwe aluminiyamu wosakanikirana ndi bulauni amakhala ndi anthracite ndi zolembera zachitsulo, kuphatikiza bauxite wothira.Aluminium yosakanikirana yoyera yokhala ndi kuuma kwapamwamba imagwiritsidwa ntchito ndi ogwiritsa ntchito apamwamba, chifukwa imakhala ndi mphamvu yodula bwino komanso kupukuta bwino, ndipo imagwiritsidwa ntchito kwambiri ngati chitsulo cha carbon, alloy steel, chitsulo chopukutira, bronze wolimba, ndi zina. bwino kwambiri komanso mowala kwambiri,
Aluminium yophatikizika ya bulauni imagwiritsidwa ntchito pamsika wokulirapo, ndipo imagwiritsidwa ntchito kwambiri ngati chitsulo chozimitsidwa, chitsulo chothamanga kwambiri, ndi chitsulo champhamvu cha kaboni kuti achotse ziboliboli pamtunda, ndipo kugaya kwake sikuwala ngati koyera. aluminiyamu wosakanikirana.
