Umsebenzi wokunqanda ukugqwala kwepuleti lensimbi elivalwe ngombala

Umbala camera steel plate ubizwa nangokuthi organic camera steel platenoma ipuleti lensimbi elakhiwe ngaphambili. Njengendlela yokukhiqiza eqhubekayo yamakhoyili, amapuleti ensimbi anombala angahlukaniswa ngezindlela ezimbili: i-electro-galvanized kanye ne-hot-dip galvanized.

Ngesikhathi esifanayo, i-electro-galvanizing iyindlela yokwenza upende ofakwe ngegolide- "ungqimba lwensimbi ye-zinc noma i-zinc alloy" ngokusebenzisa i-electroplating.

I-hot-dip galvanizing, eyaziwa nangokuthi i-hot-dip galvanizing, iwukucwilisa imikhiqizo yensimbi edinga ukulungiswa ensimbi encibilikisiwe ye-zinc ukuze kubonakale ukunameka kwensimbi yokulungisa. Uma kuqhathaniswa ne-electroplating, i-metal hot-dip coating ishubile; ngaphansi kwendawo efanayo, inokuphila okude.

Ukugqwala kongqimba olunamanzi okucwilisa ashisayo endaweni yensimbi kulingana nalokho kwe-zinc emsulwa. Ukugqwala kwe-zinc emkhathini kufana nenqubo yokugqwala kwensimbi ngaphansi kwezimo zomoya. Ukugqwala kwe-Chemical oxidation kwenzeka, ukugqwala kwe-electrochemical kwenzeka endaweni ye-zinc, futhi ukufiphala kwefilimu yamanzi kwenzeka. Esimweni esine-acidic engathathi hlangothi noma ebuthakathaka, imikhiqizo yokugqwala eyakhiwe ungqimba lwensimbi enamathangi ayizinhlanganisela ezingancibiliki (i-zinc hydroxide, i-zinc oxide, ne-zinc carbonate). Le mikhiqizo izohlukaniswa ngokufakwa futhi yakhe ungqimba oluncane oluncane.

Ngokuvamile ingafinyelela ukujiya okungu-8μm”. Lolu hlobo lwefilimu lunogqinsi oluthile, kodwa alumane nje luncibilike emanzini, futhi lunokunamathela okuqinile. Ngakho-ke, ingadlala umgoqo phakathi komkhathi kanye neshidi elinothayela. Vimbela ukugqwala okwengeziwe. Isendlalelo esinezinsimbi sonakaliswa ngesikhathi sokulungiswa, futhi ingxenye yensimbi ivezwa emkhathini.

Ngalesi sikhathi, i-zinc nensimbi zakha ibhethri elincane. Amandla e-zinc aphansi kakhulu kunalawo ensimbi. Njenge-anode, i-zinc inomphumela okhethekile wokulungisa i-anode ku-substrate yepuleti lensimbi ukugwema ukugqwala kwepuleti lensimbi.

Ibhodi elinombala liwuhlobo lwe-liquid coating, olusetshenziselwa ukuhlanza ubuso bensimbi ngebhulashi noma i-roller. Ngemuva kokushisa nokuphulukisa, ifilimu yepende enobukhulu obufanayo ingatholakala.
