Dab tsi ntawm cov kav dej galvanized suav nrog?
Galvanized kav feem ntau muaj xws li txias-dip galvanized steel kav thiab kub-dip galvanized steel kav. Txawm li cas los xij, txij li cov kav dej txias-dip galvanized steel kav tau raug txwv, cov kav dej kub-dip galvanized steel yog tam sim no siv. Nov yog cov ntsiab lus rau ob hom:
Txias-dip galvanized steel yeeb nkab: Kuj hu ua electro-galvanized, tus nqi ntawm galvanizing tsawg dua, txog 10-50g / m2, yog li nws cov corrosion kuj yog ntau dua li cov yeeb nkab kub-dip galvanized. Txij li qhov zoo yog qhov nyuaj rau kev lees paub, feem ntau cov tuam txhab lag luam niaj hnub tsis siv cov txheej txheem no, thiab tsuas yog qee lub lag luam me nrog cov nplai me me thiab cov khoom qub tseem siv tau. Tam sim no, Ministry of Construction tau maj mam ua cov kav dej txias-galvanized nrog cov cuab yeej rov qab.
Kub-dip galvanized steel yeeb nkab: Nws yog ib txoj hauv kev uas tsim cov txheej txheem alloy los ntawm kev ua haujlwm molten hlau nrog cov hlau matrix, yog li nruj sib txuas cov matrix thiab txheej. Cov txheej txheem ntau lawm ntawm cov kav dej kub-dip galvanized suav nrog thawj zaug cov kav hlau kom tshem tawm cov hlau oxide ntawm qhov chaw, tom qab ntawd ntxuav lawv nrog ammonium chloride los yog zinc chloride aqueous tov, thiab thaum kawg xa lawv mus rau kub-dip plating tank kom tiav cov txheej. txheej txheem. Vim nws cov txheej txheej, muaj zog adhesion thiab kev pab lub neej ntev, nws yog dav siv hauv kev tiv thaiv hluav taws, hluav taws xob, txoj kev loj thiab lwm yam. Tsis tas li ntawd, lub xeev tseem tawm tswv yim rau kev siv cov kav dej kub-dip galvanized ib ntus.
