Galvanized kav tau muab faib ua cua sov-galvanized steel kav thiab txias-galvanized steel kav, uas txias galvanized steel kav tau maj mam tshem tawm.
1. Kub -dip galvanized yeeb nkab / kub -dip galvanized steel yeeb nkab
Cov hlau kub-dip galvanized reacts nrog cov hlau-raws li cov tshuaj tiv thaiv los tsim cov txheej txheem alloy, uas sib txuas cov substrate thiab txheej. Kev tsim cov kav dej kub-dip galvanized yog khaws cov kav hlau ua ntej kom tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel. Tom qab pickling, ntxuav nws los ntawm ammonium chloride los yog zinc chloride dej tov los yog ammonium chloride thiab zinc chloride hybrid dej tov. , Thiab ces xa mus rau qhov kub immersion zawj.
Kub-dip galvanized steel yeeb nkab yog ib qho nyuaj rau lub cev thiab tshuaj lom neeg cov tshuaj tiv thaiv ntawm cov yeeb nkab steel matrix thiab melting plating kua, ua ib tug nruj zinc hlau alloy txheej nrog corrosion kuj. Lub alloy txheej yog kev sib xyaw nrog cov ntshiab zinc txheej thiab cov yeeb nkab steel matrix. Yog li ntawd, kub-dip galvanized steel yeeb nkab muaj qhov zoo ntawm cov txheej txheem plating, muaj zog adhesion, thiab kev pab lub neej ntev.
2. Cov yeeb nkab txias galvanized / txias galvanized steel yeeb nkab
Txias galvanized yog electroplating. Tus nqi ntawm galvanizing yog tsawg heev, tsuas yog 10-50g/m2. Nws qhov kev tiv thaiv corrosion nws tus kheej txawv ntau dua li cov kav dej kub-dip galvanized. Txhawm rau kom ntseeg tau qhov zoo, cov tuam txhab tsim cov yeeb nkab galvanized tsis siv electroplating (txias galvanized). Tsuas yog cov tuam txhab me me thiab laus-fashioned me siv electroplating, tau kawg, lawv cov nqi kuj pheej yig. Cov zinc txheej thiab steel yeeb nkab matrix ntawm txias galvanized steel kav yog txheej ntawm nws tus kheej. Vim tias cov zinc txheej nyias nyias, cov zinc txheej tsuas yog txuas nrog cov yeeb nkab steel matrix thiab yooj yim poob tawm. Yog li ntawd, corrosion kuj ntawm txias galvanized steel kav yog tsis zoo. Yog li ntawd, nyob rau hauv cov tsev tshiab tsim, cov kav dej txias galvanized steel tau txwv tsis pub ua dej thiab cov kav dej.
Cov txheej txheem ntau lawm ntawm galvanized kav
Cov txheej txheem ntau lawm ntawm galvanized steel kav belongs rau cov secrets ntawm ntau lub tuam txhab, yog li nws tsuas tuaj yeem muab cov txheej txheem dav dav: A. Kev nyeem ntawv steel; B. Cua sov; C. Kub-dov perforation; D. Txiav taub hau; E. Picky; f. Kho; G. Lubrich; h. Txias Rolling processing; i. Daim tawv nqaij; J. Khoom -soluble tshav kub kho; k. Ncaj; l. Txiav lub raj; m. Picky; n. Cov khoom kuaj.
