Galvanized Muaj Zoo Tshaj Rau Kev Nyab Xeeb Kev Nyab Xeeb Cuam Tshuam

Ib zaj yeeb yaj kiab tiv thaiv yog yooj yim los ua rau ntawm qhov chaw ntawm chav sov, yog li kev siv ntau tshaj plaws ntawm zinc yog nyob rau hauv kev lag luam galvanizing. Nws yog tsuas yog siv rau txheej txheej ntawm cov hlau thiab steel cov txheej txheem (xws li cov ntawv galvanized), thiab yog dav siv hauv kev lag luam xws li tsheb, kev tsim kho, nkoj, thiab kev lag luam teeb pom kev. Tom qab xyoo pua 21st, cov tebchaws sab hnub poob tau pib sim siv cov ntawv txhuas zinc vov ua cov ntaub vov npog. Kev pab lub neej tuaj yeem ntev npaum li 120-140 xyoo, thiab nws tuaj yeem tsim kho dua tshiab. Qhov kev pab cuam lub neej ntawm kev siv cov ntawv galvanized hlau ua cov ntaub ntawv vov tsev yog feem ntau 5-10 xyoo. Cov. Tom qab 21st caug xyoo, tus nqi ntawm qhov kub-dip galvanizing ntawm cov hlua steel tau nce ntau. Electro-galvanization tseem siv, tab sis hom no feem ntau siv rau txheej txheej nyias nyias thiab nyias qhov chaw tiav. Kev siv cov xim muaj hlau-zinc yog lwm txoj kev txheej txheej; rau cov khoom siv uas muaj kev sib txuas nrog dej, xws li cov khoom siv loj hauv steel siv hauv nkoj, txuas hniav thiab cov roj av thiab cov roj ntsha, lawv tsuas yog yuav tsum txuas nrog cov kav hlau loj. Muaj kev tiv thaiv, tab sis cov zinc thaiv yuav tsum tau hloov tsis tu ncua.
