Dab tsi yog qhov cuam tshuam ntawm lub sijhawm ziab ntev ntev rau cov kav dej steel?

Thaum cov yeeb nkab steel coated nrog cov kuab tshuaj tau qhuav hauv qhov cub kom qhuav, lub sijhawm ziab ntev ntev tuaj yeem muaj ob qhov cuam tshuam: ib qho yog ziab ntev heev ntawm qhov kub siab dua, thiab lwm qhov yog qhov ziab ntev heev ntawm qhov kub thiab txias. Yog tias lub sij hawm ziab ntev dhau ntawm qhov kub siab dua, nws yuav ua rau cov kuab tshuaj hnyav dhau, ua rau kub hnyiab thiab yellowing ntawm cov yeeb nkab steel. Xws li cov kuab tshuaj poob nws cov txiaj ntsig galvanizing-pab thiab ua rau tsis muaj galvanizing. Ntawm qhov tod tes, yog tias lub sijhawm ziab ntev dhau ntawm qhov kub qis, cov dej noo hauv cov kuab tshuaj tsis tuaj yeem evaporate sai. Raws li cov dej noo concentrates mus rau qhov kawg ntawm cov yeeb nkab steel qhov, nws yuav nyob twj ywm rau ntawm phab ntsa sab hauv ntawm lub qhov ntawm ob qho kawg, diluting cov kuab tshuaj thiab tsim cov kev mob zoo rau oxidation. Qhov no tuaj yeem ua rau plam galvanizing ntawm cov phab ntsa sab hauv ntawm lub qhov ntawm ob qhov kawg thiab qhov tshwm sim ntawm "explosion" thaum immersion galvanizing.
