Kev faib tawm
Raws li kev tsim khoom thiab kev ua haujlwm, nws tuaj yeem muab faib ua pawg hauv qab no:
a) Kub dip galvanized steel kauj.Lub nyias steel kauj yog immersed nyob rau hauv lub molten zinc da dej kom lub nyias steel kauj nrog ib txheej ntawm zinc adhere rau nws nto.Tam sim no, nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing tas li, uas yog, galvanized steel coils yog tsim los ntawm kev txuas txuas txuas ntxiv dov steel phaj hauv lub plating tank nrog zinc molten;
b) Alloyed galvanized steel kauj.Hom steel kauj no kuj yog tsim los ntawm txoj kev kub dip, tab sis tam sim ntawd tom qab nws tawm ntawm qhov zawj, nws yog rhuab mus txog 500 ℃ los ua ib tug alloy txheej ntawm zinc thiab hlau.Qhov no galvanized kauj muaj cov xim zoo adhesion thiab weldability;
c) electrogalvanized ntawv hlau coils.Lub galvanized steel kauj ua los ntawm txoj kev electroplating muaj kev ua haujlwm zoo.Txawm li cas los xij, cov txheej txheej yog thinner, thiab corrosion kuj tsis zoo li cov kub-dip galvanized coils;
d) Ib sab thiab ob sab sib txawv galvanized steel coils.Ib sab galvanized steel coils, piv txwv li cov khoom uas yog galvanized ntawm ib sab.Nws muaj kev hloov pauv tau zoo dua li ob sab galvanized coils hauv vuam, pleev xim, kho xeb, kev ua haujlwm, thiab lwm yam. Yuav kom kov yeej qhov tsis txaus ntawm cov zinc tsis muaj coated ntawm ib sab, muaj lwm galvanized coil coated nrog ib txheej nyias ntawm zinc ntawm lwm sab, uas yog, ob tog sib txawv galvanized kauj;
e) Alloy, composite galvanized steel kauj.Nws yog cov hlau coil ua los ntawm zinc thiab lwm yam hlau xws li txhuas thiab zinc, lossis txawm tias sib xyaw plated.Cov hlau kauj no muaj ob qho tib si zoo heev los tiv thaiv xeb thiab zoo txheej txheej.
Ntxiv rau cov saum toj no tsib, muaj xim coated galvanized steel kauj, luam ntawv coated galvanized steel coils, PVC laminated galvanized steel coils, thiab lwm yam. Tab sis feem ntau siv yog tseem kub dip galvanized steel kauj.
Galvanized steel coils tuaj yeem muab faib ua kev siv dav dav, kev siv lub ru tsev, kev siv vaj huam sib luag sab nrauv, kev siv cov qauv, cov nplais pobzeb vaj huam sib luag siv, siv kos duab thiab kos duab sib sib zog nqus.
Yog vim li cas qhov nto ntawm lubgalvanized ximl yog coated nrog ib txheej ntawm zinc nyob rau saum npoo ntawm cov hlau yog tiag tiag vim hais tias cov hlau phaj yog yooj yim oxidized los ntawm oxides xws li dej nyob rau hauv cov huab cua, thiab yog li corroded, thiab ib txheej ntawm zinc yog tiag plated kom zoo dua tiv thaiv cov hlau.Galvanized coil muaj ob qhov zoo, ib qho yog adhesion thiab lwm yam yog weldability.Nws yog vim ob qhov zoo uas nws tau siv dav hauv kev tsim kho, kev lag luam, kev lag luam tsheb thiab kev lag luam.Lwm qhov tseem ceeb yog kev tiv thaiv corrosion, uas tuaj yeem tsim cov txiaj ntsig zoo hauv kev tsim cov khoom siv hauv tsev.
