Galvanized ntawv yog ib lub phaj hlau nrog ib txheej ntawm zinc plated rau saum npoo. Galvanizing yog ib qho kev siv nyiaj txiag thiab kev tiv thaiv xeb uas feem ntau siv, thiab li ntawm ib nrab ntawm lub ntiaj teb zinc ntau lawm yog siv rau hauv cov txheej txheem no.
Lub luag haujlwm ntawmgalvanized ntawv
Galvanized steel phaj yog los tiv thaiv corrosion ntawm cov hlau phaj kom ntev nws cov kev pab cuam lub neej, coated nrog ib txheej ntawm hlau zinc nyob rau saum npoo ntawm steel phaj, zinc-coated steel phaj yog hu ua galvanized phaj.
Classification ntawm galvanized ntawv
Raws li kev tsim khoom thiab kev ua tiav tuaj yeem muab faib ua pawg hauv qab no:
① Kub dip galvanized steel phaj. Cov ntawv hlau yog immersed nyob rau hauv melted zinc tank thiaj li hais tias qhov saum npoo yog adhered rau ib txheej ntawm zinc sheet hlau. Tam sim no, nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing tas li, uas yog, txuas ntxiv mus rau ntawm cov hlau phaj hauv melting zinc plating tank los ua galvanized steel daim hlau;
② Alloyed galvanized steel phaj. Cov phaj hlau no kuj yog ua los ntawm kub dipping, tab sis tom qab lub tank tawm, nws yog tam sim ntawd rhuab mus txog 500 ° C los tsim ib tug alloy zaj duab xis ntawm zinc thiab hlau. Cov ntawv galvanized muaj zoo adhesion thiab weldability ntawm txheej.
③ Hluav taws xob galvanized steel phaj. galvanized steel phaj ua los ntawm electroplating muaj kev ua haujlwm zoo. Txawm li cas los xij, cov txheej txheej yog nyias thiab qhov kev tiv thaiv corrosion tsis zoo li cov ntawv kub-dip galvanized.
④ Ib sab plated thiab ob sab galvanized steel phaj. Ib sab galvanized steel, uas yog, cov khoom uas tsuas yog galvanized ntawm ib sab. Nws muaj qhov hloov tau zoo dua li ob sab galvanized ntawv hauv vuam, txheej, kev kho xeb, kev ua haujlwm thiab lwm yam. Txhawm rau kov yeej qhov tsis txaus ntawm cov zinc tsis muaj coated ntawm ib sab, muaj ib daim ntawv galvanized coated nrog ib txheej nyias ntawm zinc ntawm sab nraud, uas yog, ob sab sib txawv galvanized ntawv;
⑤ Alloy, composite galvanized steel phaj. Nws yog ib lub phaj hlau ua los ntawm zinc thiab lwm yam hlau xws li txhuas, txhuas, zinc, thiab txawm plating. Cov phaj hlau no tsis tsuas yog muaj kev ua haujlwm zoo los tiv thaiv xeb, tab sis kuj muaj cov txheej txheem zoo;
Ntxiv rau tsib yam saum toj no, muaj xim galvanized steel phaj, luam coated galvanized steel phaj, polyvinyl chloride laminated galvanized steel phaj thiab lwm yam. Tab sis feem ntau siv yog tseem kub dip galvanized ntawv.
Qhov tshwm sim ntawm galvanized ntawv
Deg lub xeev: Vim hais tias ntawm cov kev kho mob sib txawv nyob rau hauv cov txheej txheem plating, lub nto ntawm lub phaj galvanized kuj txawv, xws li zoo tib yam zinc paj, zoo zinc paj, ca zinc paj, zinc paj thiab phosphating nto.
