Dab tsi yog qhov cuam tshuam ntawm ntau lub sij hawm ziab rau cov kav hlau steel?

Thaum cov yeeb nkab steel coated nrog cov kuab tshuaj tau qhuav hauv qhov cub kom qhuav, lub sijhawm ziab ntau dhau tuaj yeem muaj ob qhov cuam tshuam: ib qho yog lub sijhawm ziab ntev heev ntawm qhov kub siab dua, thiab lwm qhov yog lub sijhawm ziab ntev heev ntawm qhov kub thiab txias. Yog tias lub sijhawm ziab ntev dhau ntawm qhov kub siab dua, cov kuab tshuaj yuav dhau los ua kom sov, ua rau scorching thiab yellowing ntawm cov yeeb nkab steel. Xws li cov kuab tshuaj yuav poob nws cov txiaj ntsig-pab thiab ua rau galvanizing omissions. Ntawm qhov tod tes, yog tias lub sijhawm ziab ntev dhau ntawm qhov kub qis, cov dej noo hauv cov kuab tshuaj yuav tsis evaporate sai. Thaum cov dej noo nkag 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 galvanizing omissions ntawm cov phab ntsa sab hauv ntawm lub qhov ntawm ob qho kawg thiab qhov tshwm sim ntawm "kev tawg" (kev tshem tawm sai ntawm zinc kua) thaum lub sij hawm immersion galvanizing.
