Galvanized steel hlau
Galvanized steel hlau
Thaum cov zinc nyob rau hauv lub xeev cov kua, lub kub dipped galvanized steel hlau undergoes complex lub cev thiab tshuaj cov tshuaj tiv thaiv tsis tau tsuas yog lub tsho tiv no cov hlau nrog ib tug tuab txheej ntawm ntshiab zinc, tab sis kuj tsim ib tug zinc-hlau alloy txheej.
Khaws cia
Kub Dip Galvanized xaim muaj ib txheej tuab thiab ntom ntom nti zinc npog saum npoo ntawm cov hlau sib tiv thaiv thiab tiv thaiv cov hlau matrix los ntawm corrosion.
Ductility
Vim tias zinc muaj qhov zoo ductility thiab nws cov txheej txheej alloy ua rau lub hauv paus ruaj khov, cov khoom kub dip tuaj yeem ua kom txias txias, dov, kos, khoov, thiab lwm yam yam tsis muaj kev puas tsuaj rau txheej.
Neeg kho tshuab
Tom qab kub-dip galvanizing, nws yog sib npaug rau kev kho annealing, uas tuaj yeem txhim kho cov khoom ntawm cov hlau matrix zoo, tshem tawm cov kev ntxhov siab thaum tsim thiab vuam ntawm steel qhov chaw, thiab yog qhov tsim nyog rau tig cov khoom siv hlau.
Qhov saum npoo ntawm kub dip galvanized hlau yog ci thiab zoo nkauj.Nws muaj cov hlau-zinc alloy txheej, uas yog densely bonded thiab exhibits tshwj xeeb corrosion kuj nyob rau hauv marine ntsev tsuag cua thiab muaj cua.
galvanized txheej ntawm galvanized hlau yog tsim los ntawm zinc nyob rau hauv ib tug high-kub kua lub xeev nyob rau hauv peb kauj ruam:
Qhov saum npoo ntawm galvanized hlau puag yog yaj los ntawm cov kua zinc los ua zinc-hlau alloy theem txheej;
Cov zinc ions nyob rau hauv cov hlau alloy ntxiv diffuse rau lub matrix los tsim ib txheej zinc-hlau miscibility;
Qhov saum npoo ntawm txheej alloy yog surrounded los ntawm zinc txheej.
Daim ntawv thov ntawm zinc coated steel hlau kuj tau nthuav dav nrog kev txhim kho kev lag luam thiab kev ua liaj ua teb.Yog li ntawd, galvanized steel hlau yog dav siv nyob rau hauv kev lag luam (xws li cov cuab yeej siv tshuaj, roj av, kev tshawb nrhiav dej hiav txwv, cov qauv hlau, kev xa hluav taws xob, kev tsim nkoj, thiab lwm yam), kev ua liaj ua teb (xws li cov dej txau dej, chav rhuab), thiab kev tsim kho (xws li. dej thiab roj kis tau tus mob, xaim npog, thiab lwm yam).Cov kav dej, scaffolding, tsev, thiab lwm yam), txuas hniav, kev thauj mus los, thiab lwm yam, nws tau siv dav hauv xyoo tas los no.Vim hais tias galvanized carbon steel hlau pas nrig muaj cov yam ntxwv ntawm zoo nkauj tsos thiab zoo corrosion kuj, nws daim ntawv thov ntau yog ua ntau thiab ntau dua.
