Lapho ukwakhiwa kwesakhiwo noma ukuhlobisa ngezinga elikhulu,ikhoyili eyenziwe ngopende ngaphambili (ikhoyili ye-ppgi)ingasetshenziswa.Iyini ikhoyili ye-ppgi?Ikhoyili ye-ppgi inokumelana nokugqwala okuhle, futhi kulula ukuyicubungula nokuyishintsha.Ilula kunezinye izinto zokwakha, ngakho-ke ikhoyili ye-ppgi izothola ukunakwa okukhulu emakethe yokwakha.
Ippgi ikhoyilisisebenza emikhakheni eminingi, kuhlanganise nezokwakha, izinto zasendlini kanye nezokuthutha.Emkhakheni wokwakha, ngoba ikhoyili yensimbi eboshiwe yepuleti enombala enesisindo esincane, ubuhle nokumelana nokugqwala, isetshenziswa kabanzi ukwakha uphahla nezindonga zezakhiwo zezimboni nezentengiselwano ezifana nezitshalo zesakhiwo sensimbi, izindawo zokugcina izimpahla, amafriji, njll. emkhakheni wezinto zasendlini, ikhoyili ye-ppgi isetshenziselwa ukukhiqiza izindawo eziqandisini, ama-oven microwave nezinye izinto zasendlini.Mayelana nezokuthutha, ikhoyili ye-ppgi isetshenziswa ekukhiqizeni nasekucubunguleni i-pan kawoyela, izingxenye zangaphakathi zemoto, njll.
Ikhoyili ye-ppgi isebenzisa ikhoyili yensimbi enombala enekhoyili/ipuleti lensimbi njengesisekelo sekhoyili/ipuleti.Ngaphezu kokuvikela i-zinc, i-organic coating on the zinc layer idlala indima yokumboza nokuhlukanisa ukuvimbela ikhoyili yensimbi/ipuleti ukuthi lingagqwali.Impilo yayo yesevisi yinde kunaleyo yekhoyili/ipuleti lensimbi.Kubikwa ukuthi impilo yesevisi yepuleti yensimbi eboshwe yinde ngo-50% kunekhoyili yensimbi.
Kodwa-ke, ezifundeni ezihlukene kanye nezingxenye ezihlukene zokusetshenziswa, impilo yesevisi yekhoyili ependwe ngaphambili enokuqukethwe okufanayo kwe-zinc, ukumbozwa okufanayo kanye nokuqina okufanayo kokugqoka kuyoba okuhluke kakhulu.Isibonelo, ezindaweni zezimboni noma ezindaweni ezisogwini, ngenxa yomphumela wegesi ye-sulphur dioxide noma usawoti emoyeni, izinga lokugqwala liyashesha futhi impilo yesevisi iyathinteka.
