Mabhandi ekushongedza eChina eAluminium Oxide ane mutengo weAruminiyamu Oxide
Pepa rejecha chinhu chisingakoshi, uye rinoshandiswa zvakanyanya mumhando dzakasiyana dzemafuru dzakadai semafoni, mota, uye zvigadzirwa zvehuni. Uyezve, pepa rejecha rinoita basa rakakosha mukuvaka pendi. Pepa rejecha rinowanzo kamurwa kuita pendi rejecha rakaoma, pendi remvura, uye pendi responji. Chinhu chavanoziva ndechekuti vanoshandisa ma binders kubatanidza ma abrasives akasiyana uye ma sandpaper matrices pamwe chete. Kubatana pamusoro pezvikamu zvejecha kwakasimba, zvichiita kuti pendi rejecha rigare kwenguva refu, zvikamu zvacho zvifanane, uye mhedzisiro yekupukuta yakanaka.
Mukana uri pakati pejecha remvura sandpaper diki kana tichienzanisa nesandpaper yakaoma, uye marara anogadzirwa nekukuya dikiwo. Kana akashandiswa nemvura, marara acho anobuda pamwe chete nemvura, uye ipapo kupinza kwenzvimbo yesandpaper kunochengetwa.
