Uhlolojikelele lwekhoyili ye-PPGI/PPGL
I-PPGI noma i-PPGL (ikhoyili yensimbi enemibala enemibala noma ikhoyili yensimbi ependwe kusengaphambili) iwumkhiqizo owenziwe ngokufaka ungqimba olulodwa noma ezimbalwa zezinto eziphilayo phezu kwepuleti lensimbi ngemva kokwelashwa kwangaphambili ngamakhemikhali njengokukhipha amafutha kanye ne-phosphating, bese ubhaka nokwelapha. Ngokuvamile, ishidi elinothayela elishisayo-diphu noma ipuleti le-Zinc le-dip elishisayo nepuleti eline-electro-galvanized lisetshenziswa njengama-substrates.

Inzuzo kanye Nesicelo
I-Hot-dip Al-Zn substrate yamukela ishidi lensimbi le-Al-Zn lokucwilisa elishisayo (55% Al-Zn) njenge-substrate esanda kugqunywa, futhi okuqukethwe kwe-Al-Zn kuvamise ukuba ngu-150g/㎡ (izinhlangothi ezimbili). Ukumelana nokugqwala kweshidi elishisayo lokucwilisa liphindwe izikhathi ezingu-2-5 kuneshidi elifakwe emanzini ashisayo. Ukusetshenziswa okuqhubekayo noma kwezikhawu emazingeni okushisa afika ku-490°C ngeke kukhiphe oxidize kakhulu noma kukhiqize isikali. Ikhono lokukhombisa ukushisa nokukhanya liphindwe izikhathi ezingu-2 kunelensimbi efakwe idiphu eshisayo, futhi ukubonakala kukhulu kuno-0.75, okuyindawo ekahle yokwakha yokonga amandla. I-electro-galvanized substrate isebenzisa ishidi elifakwe i-electro-galvanized njenge-substrate, futhi umkhiqizo otholwe ngokumboza upende we-organic kanye nokubhaka uyishidi elifakwe umbala nge-electro-galvanized. Ngenxa yokuthi ungqimba lwe-zinc lweshidi le-electro-galvanized lincane, okuqukethwe kwe-zinc kuvame ukuba ngu-20/20g/m2, ngakho lo mkhiqizo Awufanele ukusetshenziswa ekwenzeni izindonga, uphahla, njll. ngaphandle. Kodwa ngenxa yokubukeka kwayo okuhle nokusebenza okuhle kakhulu kokucubungula, ingasetshenziswa ikakhulukazi ezintweni zasendlini, umsindo, ifenisha yensimbi, umhlobiso wangaphakathi, njll izikhathi ezingaba ngu-1.5.
