235 galvanized ntawv
Lus piav qhia luv luv:
Galvanized ntawv yog hais txog cov hlau phaj nrog ib txheej ntawm zinc rau ntawm qhov chaw.Galvanizing yog ib qho kev lag luam thiab kev tiv thaiv xeb feem ntau siv.Txog ib nrab ntawm lub ntiaj teb zinc ntau lawm yog siv rau hauv cov txheej txheem no.
Nws tuaj yeem muab faib ua pawg hauv qab no raws li kev tsim khoom thiab kev ua haujlwm:
① Kub dip galvanized steel phaj.Cov ntawv hlau yog immersed nyob rau hauv molten zinc da dej kom ib txheej ntawm zinc yog adhered rau nws nto.Tam sim no, cov txheej txheem galvanizing tsis tu ncua yog siv, uas yog, dov steel phaj yog txuas ntxiv mus rau hauv lub zinc melting da dej kom ua rau cov galvanized steel phaj;
② Alloyed galvanized steel ntawv.Hom steel phaj no kuj yog ua los ntawm kub dip txoj kev, tab sis nws yog rhuab mus txog 500 ℃ tam sim ntawd tom qab tawm ntawm qhov zawj los ua ib tug alloy zaj duab xis ntawm zinc thiab hlau.Cov ntawv galvanized muaj zoo txheej adhesion thiab weldability;
③ Electro galvanized steel ntawv.Cov ntawv hlau galvanized 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 tsis zoo galvanized steel ntawv.Ib sab galvanized steel phaj, piv txwv li cov khoom galvanized nkaus xwb ntawm ib sab.Nws muaj qhov hloov tau zoo dua li ob sab galvanized ntawv hauv vuam, txheej, kev kho mob thiab kev ua haujlwm.Txhawm rau kom kov yeej qhov tsis zoo ntawm tsis txheej zinc ntawm ib sab, muaj lwm yam ntawm cov ntawv galvanized coated nrog nyias txheej ntawm zinc ntawm lwm sab, uas yog, ob-sided tsis zoo galvanized ntawv;
⑤ Alloy, composite galvanized steel ntawv.Nws yog ib qho hlau uas ua los ntawm zinc thiab lwm yam hlau xws li txhuas, txhuas thiab zinc, thiab txawm tias cov phaj sib xyaw plated.Hom steel phaj no tsis tsuas yog muaj kev ua haujlwm zoo tiv thaiv xeb, tab sis kuj muaj cov txheej txheem zoo;
Ntxiv rau cov saum toj no tsib, muaj xim galvanized steel phaj, luam ntawv coated galvanized steel phaj, PVC laminated galvanized steel phaj, thiab lwm yam. Txawm li cas los xij, feem ntau siv yog tseem kub-dip galvanized phaj.
