Isanti emhlophe ye-corundum, i-white corundum powder, i-brown corundum kunye nezinye i-abrasives ziyi-abrasives eziqhelekileyo eziqhelekileyo, ngakumbi i-white corundum powder, eyona nto ikhethiweyo yokuqala yokupolisha kunye nokugaya.Ineempawu zekristale enye, ubunzima obuphezulu, ukuzilola kakuhle, kunye nokusila kunye nokusebenza kokupholisha.Izinto eziluncedo ezifana nokuphakama ziye zasetyenziswa kwaye zakhuthazwa kumashishini ahlukeneyo.Ngoko, unokukhetha njani xa upholisha?
Ukukhetha abrasive
I-Abrasive ngumzimba oyintloko odlala indima yokusika kwinkqubo yokugaya.Ijongene ngqo nomsebenzi wokusika kwaye iyona nto ibalulekileyo kwivili lokugaya ukuvelisa umphumo wokugaya.I-abrasive kufuneka ibe yi-brown corundum eveliswe yi-Xinli ekwazi ukumelana nokunxiba.Iimveliso zayo zinobunzima obuphezulu, ukumelana nobushushu, ukuzinza kwe-thermal kunye nokuzinza kweekhemikhali, kwaye kufuneka kwakhona zibe nobunzima obuthile ukuze bukwazi ukumelana namandla athile okugaya.
Umgaqo wokukhetha i-Abrasive
Xa usila izinto ezinamandla aphezulu, sebenzisa ii-corundum abrasives ezinobunzima obuphezulu.Iimathiriyeli zokusila ezinamandla aphantsi okuqina ukukhetha iziqhushumbisi ze-silicon carbide.
Ukongezelela ekuqwalaseleni amandla obunzima bezinto zokusebenza, ubunzima bezinto zokusebenza nazo zisisiseko sokukhetha xa ukhetha i-abrasives.Ngokuqhelekileyo, ubunzima be-abrasive kufuneka bube ngamaxesha angama-2-4 aphezulu kunobunzima bezinto zokusebenza.Ngaphandle koko, iinkozo ezinqabileyo ezinobunzima obuphantsi ziya kudlula ngokukhawuleza ngexesha lokusika isantya esiphezulu kwaye ziphulukene namandla okusika, okuya kwenza ukuqina kwevili kuphantsi kwaye kuchaphazele ukusika.ukusebenza kakuhle, kunye nomgangatho wokucubungula awunakuqinisekiswa.Ngoko ke, ukuphakama kobunzima bezinto zokusebenza, ukuphakama kobunzima be-abrasive kufuneka kube.
Ukukhethwa kweempawu ze-abrasive
Kufuneka kuqwalaselwe kwakhona ukwenzeka kweekhemikhali kwindlela yokusila.Kwindawo yokudibanisa, i-abrasives, i-binders, i-workpiece materials, i-fluid yokusila kunye nomoya ixhomekeke kwiimpendulo zekhemikhali ezizenzekelayo phantsi kwesenzo se-catalytic sokushisa okusila kunye namandla okugaya.Xa insimbi isetyenzisiweyo, i-abrasive igugile ikhawuleza kune-corundum abrasive xa ukugaya intsimbi.Esona sizathu siphambili soku kukusabela okunamandla kweekhemikhali phakathi kwe-silicon carbide abrasive kunye nentsimbi.
Ukongezelela, ukuzinza kwe-thermal ye-abrasive kufuneka kuqwalaselwe xa ukhetha i-abrasive.Xa ukugaya ezinye izinto ezinzima-ukugaya, ezinye iingozi zenzeka xa ummandla wokugaya ulungele ukuvelisa amaqondo aphezulu aphezulu.
