Galvanized coils feem ntau yog tsim los ntawm hlau thiab zinc. Lawv yog cov hlau coils uas tau dhau los ua cov txheej txheem galvanizing. Cov khoom siv hauv paus muaj ntau hom hlau, xws li carbon steel lossis hlau alloy. Los ntawm galvanization, steel nto yog coated nrog ib txheej ntawm zinc, yog li pab txhawb lub coil lub corrosion kuj thiab durability.
Thaum lub sij hawm tsim khoom, cov hlau ua ntej tau txais cov khoom pov tseg kom tshem tawm cov impurities saum npoo thiab ces muab tso rau hauv ib da dej ntawm zinc molten, tso cai rau zinc txheej rau daim ntawv cog lus rau steel nto. Qhov no ua rau zinc txheej zoo tiv thaiv cov hlau tiv thaiv corrosion los ntawm ib puag ncig yam xws li huab cua thiab noo noo. Tsis tas li ntawd, galvanized coils muaj kev ua haujlwm zoo heev, tso cai rau lawv ua haujlwm ntxiv rau ntau yam hlau lossis cov khoom siv.
Lub thickness ntawm zinc txheej yog ib qho tseem ceeb parameter uas txiav txim siab lub coil lub corrosion kuj. Galvanized coils nrog sib txawv zinc txheej thicknesses tuaj yeem xaiv raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau. Feem ntau, cov zinc txheej thicker muab superior corrosion kuj, txawm hais tias yam xws li tus nqi thiab qhov hnyav yuav tsum tau txiav txim siab.
Qhov saum npoo yog coated nrog ib txheej ntawm zinc. Cov txheej zinc no tsis tsuas yog txhim kho cov hlau corrosion kuj, tab sis kuj tseem txuas ntxiv nws lub neej kev pab cuam. Raws li cov khoom siv hlau tseem ceeb, galvanized coils tau siv dav hauv kev lag luam xws li kev tsim kho, kev tsim tsheb, thiab cov khoom siv hauv tsev. Ua tsaug rau lawv cov khoom siv zoo heev thiab kev ua tau zoo, lawv ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw.
