Abrasives dzinowanzoshandiswa nenzira dzakasiyana-siyana maindasitiri pezvakaitwa kusanganisira zvinoumba uye Kupedzwa yenhengo wakaita kubva siyana nezvinhu zvakadai huni, girazi, kongiri, mapurasitiki, ibwe, simbi, simbi, super-alloys uye vasiri ferrous nesimbi, uye zvakawanda zvekumwe zvinogadzirwa zvakadai zvishongo, Manyiminya uye zvemagetsi zvinoriumba.
Kare, hasha zvakashandiswa zvikurukuru Rinobva zvakasikwa zvicherwa zvakadai Emery, Goldstone jecha uye nedhaimani. Zvisinei, nhasi, kuti abrasives indasitiri ranyura zvachose zvaanoda pamusoro chakaita zvokugadzirwa zvinhu, zviri kure zvikuru yamunoti sezvamunoita uye mutengo-inobudirira kupfuura zvavo dzinongoitika vamutangira. Chakaita zvokugadzirwa zvinhu vanowanzova zvikuru mutengo-zvinobudirira sezvo avanotarisira kuva ne-zvinhu kana tsvina nzizi kwemasayendisiti kuti kuagadzira zvakadai simba chizvarwa uye simbi simbi. Nepo zvakasikwa zvicherwa vachiri zvakapararira, avanotarisira kudirwa zvikuru kushandiswa mafomu akadai pakuonekwa uye wakanaka okugadziridza nokuda kwavo yepamusoro mutengo.
The mhando nhatu chikuru kugadzirwa abrasives vari zvemapuranga, waakaita uye kusazvibata abrasives. Coated abrasives mamwe tsigiro zvakafanana pepa, jira kana. Waakaita abrasives zvinosanganisira kukuya mavhiri uye netsvimbo. Loose abrasives inoshandiswa nenyunje uye koromoka kuti, pakati pezvimwe zvinhu, kubviswa pendi nengura uye kugadzirira hukawanika matsva. Imwe neimwe hasha chigadzirwa caters kune zvakasiyana zvinodiwa tichitarisa nechepasi kumugumo nokurondedzerwa, chimiro uye kukura rokuti, panyama ayo ehupfumi (akadai zvakaoma, simba uye tembiricha nemiganhu) uye uchida zvinodiwa chaizvo nokugeda kana apedza muitiro. The zvechadenga hasha zvinhu (somuenzaniso, saizi, chimiro, simba, arambe achirema neukukutu) vari dzinonetsa wacho zvakananga kushandiswa, sezvo vari ehupfumi ari chizvaro zvinhu (somuenzaniso, nebwe, vitreous kana simbi) uye mwero porosity.
Zvikumbiro bvisa abrasives siyana pamusoro kuchenesa uye peening, kusvikira achigadzirira zvokuvakisa anodzivirira coatings kudzorerwa uye pemvura. Chinhu chikuru musika wechipiri yokusazvibata abrasives ndiyo mhepo kuchenesa uye repainting pamusoro mabhiriji uye overpasses. Kuwedzera kune izvi misika maviri, pane mazana maindasitiri mafomu apo anongoremberera abrasives inoshandiswa pamusoro gadziriro, pamusoro kuchenesa uye somunhu chezvinonhuwira dzimwe apera zvigadzirwa.
Hasha Kurira kuchenesa unosanganisira nzira dzakasiyana-siyana kuti zvinosanganisira kushandisa marudzi anoverengeka nhau propelled nemvura kana mhepo. The abrasives Vezvenhau anosiyana chaizvo, kubva mupunga hulls uye walnuts anoshongwa kuti slags siyana, Garnet uye simbi vapfurwa. Typical Kurira rokuchenesa zvicherwa zvinosanganisira staurolite, olivine, specular hematite uye Garnet. vezvenhau Man-yakaitwa kushandiswa Nokufema rokutsvaira zvinosanganisira mapurasitiki, zvemapuranga zvicherwa, zvishandiswezve girazi, simbi bara, marasha gang, mhangura gang uye nickel gang.
Kwemakore anopfuura 50, silica akanga kupfuura inowanzoshandiswa hasha nokuti hasha kwebhosvo rokutsvaira, saizvozvo coining rokuti sandblasting, sezvazvakaita mari uye nyore kushandisa.
