Txheej Thickness
Raws li tau hais,pre-galvanized Cheebtsam feem ntau tsuas yog immersed nyob rau hauv lub galvanizing da dej rau ib tug luv luv lub sij hawm, uas ua rau ib tug kuj nyias txheej.. Lub thicker zinc txheej ua los ntawm kub dip galvanization muaj kev txhim kho xeb thiab tiv thaiv corrosion tiv thaiv pre-galvanization.
Pre-Galvanization
Thaum cov khoom siv hlau siv rau hauv kev tsim cov khoom tiav tiav, lawv yuav raug galvanized ua ntej cov khoom kawg tau sib sau ua ke. Qhov no yog qhov hu uapre-galvanization, los yog "pre-gal". Nws kuj tseem hu ua "in-line", "nruam", lossis "mill" galvanizing. Qhov tseem ceeb, cov khoom siv hlau - xws li cov ntawv los yog xaim - yog galvanized siv cov txheej txheem automated ua ntej lawv raug txiav kom loj.
Cov txheej txheem automated no yuav txawv nyob ntawm seb hom kev tivthaiv yog galvanized. Feem ntau hais lus, cov khoom siv hlau tau muab tso rau hauv "galvanizing da dej" ntawm zinc molten rau lub sijhawm luv luv. Thaum cov hlau raug tshem tawm ntawm lub da dej, cov zinc ntau dhau raug tshem tawm siv lub tshuab wiper, cua riam, lossis chav dej. Qhov no yoojyim ib tug kuj nyias galvanized txheej ntawm zinc.
Kub-dip Galvanization
Covbatch kub-dip galvanizationtxheej txheem yuav immersing tag nrho cov tiav steel khoom, los yog "steelwork", nyob rau hauv ib da dej ntawm cov kua ntshiab zinc. Qhov no ua kom muaj kev tiv thaiv tag nrho ntawm cov khoom, suav nrog cov chaw sab hauv ntawm txhua qhov chaw hollow (xws li sab hauv lub raj). Kub dip galvanization kuj feem ntau ua rau cov zinc txheej tuab dua li pre-galvanization. Ib daim ntawv cog lus metallurgical ntawm cov khoom hlau thiab cov zinc txheej, muab kev tiv thaiv corrosion.
Yog tias koj tshawb nrhiav cov duab ntawm kub dipped galvanized steel, koj yuav pom cov duab ntawm cov khoom steel nrog ib tug tshwj xeeb nto qauv hu uaspangle. Spangling tuaj yeem txhim kho thaum cov zinc molten, ib zaug ua rau cov hlau, txias hauv qab nws cov ntsiab lus melting. Thaum nws nce mus txog qhov ntsuas kub no, qhov sib txawv ntawm cov atoms ntawm cov kua zinc pib npaj lawv tus kheej rau hauv cov qauv zoo, crystalline.
