Lub corrosion los yog discoloration ntawmgalvanized hlau hlaunyob rau hauv cov huab cua tshwm sim los ntawm oxygen, noo noo thiab lwm yam impurities impurities yog hu ua xeb los yog xeb.Tom qab galvanized hlau hlau xeb, nws yuav cuam tshuam rau cov tsos zoo, cuam tshuam rau kev siv, thiab txawm tias ua rau seem, yog li galvanized hlau hlau yuav tsum tau khaws cia kom zoo thiab xyuam xim tiv thaiv xeb.
A. Thaum lub thickness ntawm lub plating yog 3-4 hli, zinc adhesion yuav tsum tsawg tshaj li 460g / m, uas yog, qhov nruab nrab thickness ntawm zinc txheej yog tsis tsawg tshaj li 65 microns.
B. Thaum lub thickness ntawm lub plating yog ntau tshaj 4 hli, zinc adhesion yuav tsum tsis txhob tsawg tshaj li 610g / m, uas yog, qhov nruab nrab thickness ntawm zinc txheej yuav tsum tsis txhob tsawg tshaj li 86 microns.
C, txheej uniformity: galvanized txheej yog ib txwm sib xws nrog tooj liab sulfate tov kuaj etched tsib zaug yam tsis muaj hlau.
D, txheej adhesion;Zinc txheej ntawm cov plating qhov chaw yuav tsum tau ruaj khov ua ke nrog lub hauv paus hlau nrog txaus adhesion lub zog, thiab yuav tsis poob los yog bulge tom qab lub rauj xeem.
