Isitshixo sokuphuhlisa iUkupholisa ukucaciswa kokuxolelaemvaukufowunakukukhetha inqanaba lokupholisa elifanelekileyo ukuphepha iziphene zokupholisa okhankanywe apha ngasentla. Ngokubanzi, inkcazo yokupholisa i-picraling igqitywe ngokuqulunqwa kwekhemikhali, iimpawu zomiselo zekhemithi, iLizwe lezinto ezibonakalayo kunye nobungakanani becandelo lezinto ezimbi, ngokubhekisele kwidatha efanelekileyo.
Ngokubanzi, ilula ilula yokwenziwa kweekhemikhali ze-chimical, ikhawuleza ireyitha emvaukufowuna, kwaye icotha enye indlela ejikeleze. Kwitoti ye-carbon kunye nentsimbi ye-alloy ephantsiukuxolela, ukuphola komoya kungamkelwa emvaukufowuna. Kunye ne-ratis ye-alloy yentsimbi ye-alloy ephezuluukuxolelaOkanye ukukhululeka okuphezulu okuxolayo, emva kokuthamba kufuneka kuthathwe i-pit yokupholisa okanye ukupholisa.
Ukuba i-carbon yesixhobo se-carbon, isazisi sesixhobo sensimbi kunye nentsimbi enomxholo wekhabhoni ephezulu sipholile emvaukufowuna, i-carbide yenethiwekhi iya kutsala kumda wokudla okuziinkozo, oya kuyichaphazela kakhulu ukwenziwa kweenkonzo. Ke ngoko, olu hlobo lweengutiko luphononongwe ukuya kwi-700 ℃ ngokupholisa umoya, blast okanye ukutshiza ngokukhawuleza emva kokunyanzelwa, emva kokoukuxolelazibekwe kwimingxunya okanye iziko lokuphola kancinci.

Kwintsimbi ye-Austeritic, intsimbi yentsimbi kunye nezinye izistim ngaphandle kwenguquko yenqanaba, ukuphola ngokukhawuleza kungamkelwa ngenxa yokuba akukho nguqu iphambili kwinkqubo yokupholisa emvaukufowuna. Ukongeza, ukuphola ngokukhawuleza kuyadingeka ukufumana isakhiwo esinye kunye nokuthintela ukuphola kancinci kwentsimbi yentsimbi ye-475 ℃. Ke ngoko, olu hlobo lokuxolela lunokuba luphazanyiswa ngumoya emvaukufowuna.
Kwizitho ezipholileyo ze-moya, ezinje ngentsimbi ye-buel, intsimbi engenasitayile, isantya esiphezulu sensimbi, yonke inguquko inokwenzeka, eya kubangela uxinzelelo olukhulu kwaye oluya kwenza uxinzelelo olukhulu kwaye luza kuvelisa uxinzelelo olukhulu . Ke ngoko, olu hlobo lokuxolela kufuneka luthotyelwe kancinci emvaukufowuna.
Ngendawo emhlophe yentsimbi, enje ngentsimbi ye-chrome-nickel, ukwenzela ukuthintela ibala elimhlophe kwinkqubo yokupholisa, ukupholisa iziko kufuneka kwenziwe ngokweenkcukacha ezithile zokupholisa.
Ukuxolelayenziwe ngensimbi yentsimbi yokuphola ngokukhawuleza emvaukufowuna, ngelixa lenziwe ngentsimbi ye-Iyot inenqanaba lokupholisa elicothayo. Ukongeza, ukuxolela ngezinto ezinkulu zecandelo kufuneka ziphole kancinci emva kokuthambisa ngenxa yoxinzelelo lobushushu obukhulu, ngelixa ixolile ngamacandelo amancinci ecandelo inokuthotyelwa ngokukhawuleza emva kokubanjwa.
