Abrasives ba atisa ho sebelisoa mefuta e fapaneng mefuta e sa dithulaganyo liindasteri ho akarelletsa le ho laoleng le qete ea likarolo entseng ho tloha thepa e sa tšoaneng tse kang patsi, ka khalase, ka konkreiti, polasetiki, lejoe, tšepe, tšepe, bartolomeo-lits'epe tse kopantsoeng le non- tšepe ferrous, 'me ho feta eksotiske lihlahisoa tse kang mabenyane, Optical le dikarolo ea elektronike.
Histori, thepa khorofo ne haholo-holo tswang liminerale tsa tlhaho tse kang moralla, quartz lehlabathe le taemane. Kajeno Leha ho le joalo, ho abrasives indasteri e hoo e ka bang e itšetlehileng ka ho feletseng holim 'a thepa a maiketsetso, tse ho feta ka tsela e lumellanang ka ho sebopeho le e ka bolokang tjhelete ho feta pele ho bona tsa tlhaho. thepa maiketsetso ke ka kakaretso ngata e ka bolokang tjhelete ha ba ntse ba le tšekamelo ea ho ka dihlahiswa kapa litšila melapo ea dithulaganyo le tse hlahisang bona tse kang matla a isa molokong o mong le tšepe qhibilihisa. Ha a ntse a liminerale tsa tlhaho li ntse li atile, ba atisa ho sebediswa bakeng sa dikopo khethehileng haholo tse kang bentsa le qete bo botle ka lebaka la ho theko bona phahameng.
The tse tharo mefuta e ka sehloohong ea abrasives hlahisoeng ha ba tlotsitsoeng, bonded le abrasives hlephileng. A tlotsitsoeng abrasives na le pampiri, lesela kapa tse ling tse tšehelitsoe tšoanang. Bonded abrasives kenyeletsa mabili sila le melamu. abrasives hlephileng ba sebediswa bakeng sa ho qhomisa e le ketola tsa, har'a lintho tse ling, ho tlosa pente le mafome le ba lokisetsa ho ea bokaholimo ncha. E mong le e mofuta wa sehlahiswa khorofo tlhokometse ditlhokwa ho ditlhoko fapaneng ya ka dipehelo tsa holim tobileng fihlela qetellong, sebopeho le boholo ba karolo ea, thepa lona 'meleng (tse kang thatafala, matla le mocheso meeli) le ditlhoko tse qaqileng tsa sila itseng kapa qete tshebetso. Litšobotsi tsa boitsebiso bo khorofo (ka mohlala, boholo, sebopeho, matla segokanyipalo le thatafala) tšoaea phoso ho e sebelisa e itseng, e le ke thepa ea lintho tse bonahalang popeho (ka mohlala, lehoakhoa, vitreous kapa tšepe) le tekanyo ea ho porosity.

A bobeli kgolo maraka bakeng abrasives hlephileng ke pululo ho hloekisa le repainting ea marokho le overpasses. Ho phaella ho limmaraka tsena tse peli, ho na le tse makholo tse dikopo liindasteri moo abrasives hlephileng ba sebediswa bakeng sa ho lokisetsa holim, bokaholimo ho hloekisa le ka karolo ea lihlahisoa tse ling tse felileng.
