Peb txhais li cas los ntawm Galvanized Steel?
Cov hlau galvanized yog hais txog cov hlau tsis tu ncua uas tau coated nrog txheej tiv thaiv zinc. Qhov no yog ua los txhawm rau tiv thaiv txhua yam xeb lossis xeb. Cov galvanized steel feem ntau yog siv rau kev tsim bolts, ceev, thiab screws.
Covgalvanized hlaumuaj zog tiv thaiv corrosion los yog txhua yam degradation, txawm tias thaum lawv raug mob hnyav. Koj yuav pom tias cov hlau galvanized tuaj yeem tiv taus nyob rau hauv dej tshiab vim tsis muaj cov ntsev ntsev hauv cov dej. Thaum ua haujlwm nrog cov hlau galvanized, cov welders (lossis cov neeg ua haujlwm) yuav tsum tau ua kom paub tseeb tias lawv muaj kev tiv thaiv los ntawm cov pa phem tsim tawm thaum lub sijhawm ua haujlwm.
Peb txhais li cas los ntawm Stainless Hlau?
Stainless hlau yog muaj zog, ruaj, ruaj thiab yog tsim los ntawm kev ntxiv chromium los yog tungsten nrog rau carbon thiab hlau rau cov hlau molten. Stainless hlau yog suav hais tias zoo dua li cov hlau galvanized vim nws muab kev tiv thaiv corrosion (thaum nws los ntawm kev sib cuag nrog dej thiab ya raws). Koj yuav pom tias cov hlau tsis muaj steel tuaj yeem tiv taus cov dej ntsev thiab tsis tau corroded.
Thaum nws los txog rau vuam stainless hlau, nws yuav tsum muaj ntau yam kev txawj tshwj xeeb. Thaum cov txheej txheem vuam, cov neeg ua haujlwm thiab cov kws tshaj lij yuav tsum ua kom ntseeg tau tias qhov kub thiab txias yog tswj, cua sov yog tswj, thiab cua txias yog muab nrog qhov tseeb. Tsis tas li ntawd, cov welders yuav tsum tau ua kom zoo ntsuas uas yuav ntxiv cov fillers tsim nyog rau cov hlau uas tau welded.
Lwm qhov sib txawv ntawm cov hlau galvanized thiab stainless hlau yog tias cov hlau galvanized yog suav tias yog cov khoom siv zoo heev thiab yooj yim rau kev ua haujlwm nrog. Yog li lawv yog nyob rau hauv siab thov nyob rau hauv manufacturing units rau tsim ib tug ntau yam ntawm cov khoom.
Stainless hlau yog qhov nyuaj heev thiab nthuav tawm cov yam ntxwv ruaj khov, thiab vim qhov no, nws yog siv dav hauv kev tsim cov khoom siv dav hlau.
Qhov sib txawv ntawm Kev Npaj Cov Hlau Galvanized thiab Stainless Hlau
Cov hlau galvanized yog npaj los ntawm kev tsim cov txheej tiv thaiv tshaj cov hlau zoo tib yam. Cov txheej txheem tiv thaiv yog molten zinc, thiab cov txheej txheem hu ua kub-dipping. Lwm cov txheej txheem uas siv los npaj cov hlau galvanized yog electroplating. Nyob rau hauv cov txheej txheem no, cov hlau zoo tib yam yog dua dipped nyob rau hauv ib tug tov, tab sis nws yog ib tug electrolyte tov uas muaj zinc.
Yog tias peb xav txog qhov kev npaj ntawm cov hlau tsis muaj steel, ces nws yog ib qho laj thawj ntawm cov hlau, chromium, thiab carbon. Tag nrho cov ntaub ntawv yog tov nyob rau hauv ib qho kev faib ua feem nyob rau hauv lub molten lub xeev thiab raug tso cai kom tau hardened thaum txias. Nyob rau hauv lub kawg theem, lub stainless yog kho nrog ib tug acidic tov kom tag nrho cov impurities raug tshem tawm.
