Passivation
Passivation kev kho mob ntawm galvanized txheej tuaj yeem txo cov xeb xeb (dawb xeb) nyob rau hauv cov dej noo cia thiab kev thauj mus los.Txawm li cas los xij, kev ua haujlwm tiv thaiv corrosion ntawm cov tshuaj no tsuas yog txwv, thiab nws cuam tshuam cov adhesion ntawm feem ntau cov txheej.Hom kev kho no feem ntau tsis siv rau ntawm zinc-hlau alloy txheej.Ntxiv rau qhov du nto, raws li txoj cai, cov chaw tsim khoom yuav passivate lwm hom zinc txheej.
Oiling
Oiling tuaj yeem txo qhov corrosion ntawm steel daim hlau nyob rau hauv cov av ntub thiab kev thauj mus los.Tom qab passivation kev kho mob ntawm steel daim hlau thiab steel strips, repainting roj yuav ntxiv txo cov corrosion nyob rau hauv ntub cia tej yam kev mob.Cov roj txheej yuav tsum tau muab tshem tawm nrog lub degreaser uas tsis ua rau cov zinc txheej.
Xim foob
Los ntawm txheej txheej nyias nyias nyias nyias txheej txheej, nws tuaj yeem muab cov nyhuv tiv thaiv corrosion ntxiv, tshwj xeeb tshaj yog cov ntiv tes tiv thaiv.Nws tuaj yeem txhim kho lubricity thaum lub sij hawm molding thiab ua raws li cov txheej txheem adhesion rau cov txheej tom ntej.
Phosphating
Los ntawm kev kho phosphating, galvanized steel ntawv ntawm ntau hom txheej tuaj yeem coated yam tsis muaj kev kho mob ntxiv tshwj tsis yog kev tu ib txwm.Qhov kev kho no tuaj yeem txhim kho qhov adhesion thiab corrosion kuj ntawm txheej, thiab txo qhov kev pheej hmoo ntawm corrosion thaum khaws cia thiab kev thauj mus los.Tom qab phosphating, nws tuaj yeem siv nrog cov roj nplua nyeem tsim nyog los txhim kho kev ua haujlwm molding.
Tsis muaj kev ua
Tsuas yog thaum tus neeg txiav txim tau thov thiab yog lub luag haujlwm rau qhov tsis kho, cov hlau phaj thiab steel strips muab raws li tus qauv no tuaj yeem ua tsis tau passivation, oiling, xim sealing lossis phosphating thiab lwm yam kev kho saum npoo.
♦ Daim ntawv thov
Galvanized kaujcov khoom siv tsuas yog siv hauv kev tsim kho, kev lag luam teeb, tsheb, kev ua liaj ua teb, tsiaj txhu thiab nuv ntses thiab kev lag luam kev lag luam.Ntawm lawv, kev tsim kho kev lag luam feem ntau yog siv los tsim kev lag luam los tiv thaiv kev lag luam thiab pej xeem lub ru tsev panels, ru tsev grilles, thiab lwm yam .;lub teeb kev lag luam siv nws los tsim cov khoom siv hauv tsev, cov chimneys, cov khoom siv hauv tsev, thiab lwm yam, thiab kev lag luam tsheb yog siv los tsim cov khoom siv corrosion-resistant rau tsheb, thiab lwm yam.;Kev ua liaj ua teb, kev tu tsiaj thiab kev nuv ntses yog siv los ua zaub mov thiab kev thauj mus los, nqaij thiab cov khoom siv dej hauv tub yees ua cov cuab yeej, thiab lwm yam.;kev lag luam feem ntau yog siv los ua cov khoom khaws cia thiab kev thauj mus los, cov cuab yeej ntim khoom, thiab lwm yam.
