Vim li cas Sequins tshwm rau saum npoo ntawm Galvanized Steel Coils?

Galvanizing yog ib txoj hauv kev zoo los tiv thaiv cov hlau liab qab los ntawm qhov chaw corrosive. Coob leej paub dab tsigalvanized steel kaujyog, nws muaj ntau yam kev siv, los ntawm HVAC ductwork, tsev décor, cov thoob khib nyiab, thiab lwm yam. Nws tsis yog tsuas yog ruaj tab sis kuj corrosion resistant, yog li nws ua li cas? Cov sequins tuaj txog li cas? Cia peb kawm!

Galvanized steel kauj yog coated nrog zinc ntawm carbon steel, thiab cov txheej txheem ntawm galvanizing yog cov txheej txheem kub dip. Cov txheej txheem kub dip suav nrog dipping carbon steel hauv zinc da dej. Thaum cov khoom raug tshem tawm ntawm zinc da dej thiab txias, nws reacts nrog cov pa oxygen nyob rau hauv cov huab cua, ib qho tshuaj tiv thaiv uas ua rau zinc los ua ib feem ntawm cov hlau. Cov zinc tiav zoo nkaus li muaj crystalline lossis ci tiav, thiab thaum qhov no yog cov qauv ntawm galvanizing, yav tas los tsim cov hlau feem ntau siv vim cov tuab ntawm cov khoom tsis tuaj yeem tswj tau yooj yim. Tom qab txuas ntxiv galvanizing tau dhau los ntawm zinc da dej, qhov saum npoo ntawm cov hlau txuas txuas ntxiv yuav raug galvanized. Lub kauj khiav ntawm li 600 taw ib feeb, thiab raws li lub kauj tawm ntawm zinc da dej, nws yuav siv sij hawm ib txheej ntxiv ntawm molten zinc nrog nws, thiab cov cua kub siab yog siv los tshem tawm cov ntau dhau mus rau qhov xav tau tuab. Tom qab ntawd cov khoom raug tso cai kom txias, tsim kom muaj qhov ci ntsa iab. Galvanized thiab cov ntawv hlau yog tsim rau cov ntawv thov uas muaj kev tiv thaiv corrosion yog qhov tseem ceeb, galvanizing tuaj yeem ua rau lub neej ntev ntawm cov khoom, zoo tagnrho rau cov tuam txhab tsim khoom, thiab ua tiav kom txaus siab rau cov neeg siv khoom.
