Galvanized steel yog hais txog cov pa roj carbon zoo tib yam siv hlau uas tau raug galvanized los tiv thaiv corrosion thiab xeb ntawm cov hlau thiab txuas ntxiv kev pab cuam lub neej ntawm cov hlau. Galvanizing yog muab faib ua electro-galvanizing thiab kub-dip galvanizing. Feem ntau siv rau hauv cov phab ntsa sab nrauv, xws li iav ntaub thaiv phab ntsa, marble curtain phab ntsa, aluminium curtain phab ntsa raws li txhua kab thiab cov ntaub ntawv kev ntxhov siab, los yog siv nyob rau hauv sab nraum zoov telecommunications yees, txoj kev loj thiab lwm lub tsev qhib cua. Hlau yog hu ua galvanized steel, ntawm cov galvanizing yog muab faib ua electro-galvanizing thiab kub-dip galvanizing. Kub galvanized.
Galvanized steel ntawvyog coated nrog ib txheej ntawm hlau zinc rau ntawm qhov chaw los tiv thaiv corrosion ntawm cov nplooj ntawv steel thiab txuas lawv lub neej kev pab cuam. Qhov no zinc-coated nyias steel ntawv yog hu ua ib daim ntawv galvanized.
Ntau hom galvanized steel siv cov khoom sib txawv, xws li.
1. Kub-dip galvanized steel phaj. Ib daim hlau nyias yog immersed nyob rau hauv ib tug molten zinc da dej kom ib txheej ntawm zinc adheres rau nws nto. Tam sim no, cov txheej txheem galvanizing tas mus li yog siv rau kev tsim khoom, uas yog, cov ntawv hlau dov tau txuas ntxiv rau hauv lub plating da dej uas muaj zinc molten los ua galvanized steel daim hlau;
2. Alloyed galvanized steel phaj. Cov phaj hlau no kuj yog ua los ntawm cov txheej txheem kub dip, tab sis nws yog rhuab mus txog 500 degree tam sim ntawd tom qab tawm hauv lub tank los tsim cov hlau alloy ntawm zinc thiab hlau. Hom ntawv galvanized no muaj cov xim zoo adhesion thiab weldability;
3. Electro-galvanized steel phaj. Hom galvanized steel ntawv no tsim los ntawm txoj kev electroplating muaj kev ua tau zoo. Txawm li cas los xij, cov txheej yog nyias thiab nws cov kev tiv thaiv corrosion tsis zoo li cov ntawv kub-dip galvanized;
4. Ib sab galvanized steel phaj thiab ob sab galvanized steel phaj. Ib sab galvanized steel ntawv yog ib yam khoom uas yog galvanized ntawm ib sab. Nyob rau hauv cov nqe lus ntawm vuam, painting, anti-xeb kev kho mob, ua, thiab lwm yam, nws muaj zoo adaptability dua ob-sided galvanized nplooj ntawv. Txhawm rau kom kov yeej qhov tsis txaus ntawm ib sab tsis tau coated nrog zinc, muaj lwm hom ntawv galvanized uas yog coated nrog ib txheej nyias ntawm zinc ntawm sab nraud, uas yog, ob sab galvanized ntawv;
5. Alloy thiab composite galvanized steel los xij. Nws yog ua los ntawm zinc thiab lwm yam hlau xws li txhuas, zinc alloy lossis txawm tias cov phaj sib xyaw plated. Hom steel phaj no muaj ob qho tib si zoo heev los tiv thaiv xeb thiab cov khoom pleev xim zoo.
Lub hardness ntawm galvanized steel nyob ntawm qib steel thiab cov xwm txheej ntawm lub hauv paus phaj, thiab feem ntau yog nyob ib ncig ntawm 150 degrees Brinell.
