Loj coils ntawmgalvanized hlautuaj yeem muab faib ua kub dip galvanized hlau thiab txias galvanized hlau, qhov sib txawv ntawm ob qhov lus dag nyob rau hauv txoj kev ntawm zinc thiab zinc kom muaj nuj nqis.Kub dip galvanized steel hlau yog soaked nyob rau hauv molten zinc, kub dip galvanized zinc ceev, zinc txheej tuab xeb kev ua tau zoo heev, tab sis cov zinc tsis zoo li qub, thiab saum npoo yog tsaus, kub dip galvanized lub neej tuaj yeem ncav cuag 20 xyoo.
Txias galvanizing tseem hu ua,galvanized steel hlauyog muab tso rau hauv plating da dej, los ntawm unidirectional tam sim no qeeb hlau nto ntawm galvanized, hluav taws xob galvanized zinc yog qeeb, thiab rau kub dip galvanized thickness yog ib tshaj kaum, zinc nyias thiaj li tsis zoo xeb kuj, muab tso rau sab nraum zoov feem ntau yog ob peb lub hlis. yuav xeb, feem ntau siv rau sab nraum zoov hauv lub hnab yas.
Hloov yog rub kub dipgalvanized hlaulos yog txias galvanized hlau thib ob ua, hloov tom qab nto du thiab ci, rub thiab tensile kuj muaj zog, uas tsis yooj yim los tsim puas, feem ntau siv los tshuaj ntsuam kev lag luam yuav hloov mus rub, tam sim no koj tuaj yeem muaj cov txiaj ntsig ntawm kev txhim kho zoo, lwm yam khaub ncaws-nees, kev sib txuas lus, cov kab nrib pleb siab yuav hloov ua cov duab kos, tiv thaiv kev puas tsuaj.
Lub zog ntawm galvanized hlau: tensile lub zog yog lub zog tensile uas cov khoom tuaj yeem tiv taus ua ntej tensile tawg;Muaj ob qhov Performance index ntawm yield zog, siab yield thiab qis tawm los.Nws hais txog cov txheej txheem uas qhov kev ntxhov siab tsis nce ntxiv thaum lub deformation tseem tshwm sim hauv cov txheej txheem tensile.Thaum tus nqi quab yuam poob rau thawj zaug, qhov kev ntxhov siab loj yog lub zog tawm los, thiab lub zog tawm los yuav tsum tsawg dua li tus nqi tensile zog.
Non-proportional elongation lub zog: nws yog tsuas yog rau cov hlau tawv tsis muaj qhov taw tes tawm.Qhov kev ntxhov siab uas qhov seem elongation ntawm tus qauv ncua mus txog 0.2% ntawm qhov ntev ntawm tus txheej txheem qub yog txhais raws li qhov teev tsis sib npaug ntawm lub zog elongation.
Galvanized qhov chaw yuav tsum tau plated: qhov saum npoo ntawm qhov chaw yuav tsum tau plated yuav tsum du, thiab tsis muaj acid pickling txoj kev tsis tuaj yeem tshem tawm cov pa phem.Xws li cov xim, roj, cement, asphalt thiab ntau dhau rotten teeb meem tshuaj;Tag nrho cov welds ntawm cov tswv cuab welded yuav tsum raug kaw yam tsis muaj cua;Cov kav dej thiab cov thawv ntim khoom yuav tsum muaj qhov rau qhov tso pa tawm thiab zinc kom tsawg;Lub workpiece yuav tsum tiav welded steel yeeb nkab tsis muaj xov, yog tias xov yuav tsum tau tiv thaiv.
