GL / GC daim ntawvmuaj kev txhim kho zoo corrosion, luam tawm-muaj peev xwm thiab kev ua haujlwm tau zoo. Tshooj De-greasing pab tshem tawm cov roj thiab av los ntawm cov txheej txheem cascaded ntawm kub alkaline de-greasing, txias nce, kub nce thiab cua kub kom qhuav. Tom qab ntawv annealing tau ua nyob rau hauv qhov cub hluav taws xob ua kab rov tav lub tshuab hluav taws xob ua haujlwm hauv qhov chaw tiv thaiv kev tiv thaiv nrog qhov sib xyaw nrog nitrogen thiab hydrogen tsim nyob rau hauv lub xeev – ntawm – daim duab thev naus laus li Kev Tiv Thaiv Roj Cog siv ammonia thiab huab cua ua cov khoom nyoos.
Raus nws hauv qhov chaw da dej zinc tswj ntawm 460 degree centigrade nqa tawm kub dip galvanizing ntawm txoj kab txaij. Kev ntxuav cov chav da dej kom zoo tswj hwm kom ntseeg tau tias txhawm rau txhawm rau txhawm rau txhawm rau ua kom cov xeb ua ke nrog cov ci ntsa iab dawb ntxig spangles.Qhov galvanized coil yog chromated los txhim kho nws qhov kev tiv taus xeb dawb. Cov ntsuas hluav taws xob muaj qhov tsis tu ncua tau soj ntsuam tas li thiab cov ntawv txheeb tau ua ntu zus los ntawm kev ntsuas ntsev kom paub tseeb tias kev ua haujlwm ntawm cov txheej txheem no.
Peb tseem tuaj yeem muab cov ntawv galvanized tiaj thiab corrugated nrog qhov ntev.Galvanized corrugated ntawvtuaj yeem tsim nrog kaw siab tiv thaiv ntawm tus qauv tob, lub suab thiab dav.
Corrugated hlaupib nrogcarbon hlau ntawvuas yog tom qab ntawd nias rau hauv cov qauv peb-seem, hu ua kev txhim kho corrugations, siv qhov sib dhos ntawm cov dov hauv cov txheej txheem yob txias. Cov txheej txheem sib txawv ntawm cov menyuam tuag ua rau ntau hom kev xeb, suav nrog vuag, plaub fab thiab kaum. Cov dov txias tso cai rau cov khoom tuab thiab muaj zog uas kuj ua kom pom cov duab zoo dua li kub-tsim hlau. Tiav daim ntawv tiav yog tom qab txiav tawm mus rau qhov xav tau ntev.
