Kub Dipped Galvanized vs Galvanized Steel
Electro zinc plating (los yog electroplating)
Cov txheej txheem ntawm galvanizing no hloov cov zinc da dej nrog cov tshuaj electrolyte uas cov hlau tau them ua ntej kho. Thaum cov hlau so hauv cov tshuaj electrolyte, ib qho hluav taws xob tam sim no yog siv, hloov zinc ions rau hauv zinc hlau uas ua raws li cov hlau. Cov txheej txheem kev tshawb fawb no tsim ib txheej nyias ntawm zinc. Txawm li cas los xij, vim tias cov txheej txheej yog nyias, cov khoom tseem raug rau corrosion.
Annealing ntawm galvanized txheej
Cov txheej txheem sib xyaw ua ke kub-dip galvanizing nrog annealing, kev kho cua sov uas hloov cov khoom siv microstructure kom nws ruaj khov dua. Yog li ntawd, alloyed galvanizing tseem kub-dip plating, tab sis los ntawm ib txhij annealing nws, lub resulting hlau muaj ntau ntawm ib tug matte grey nto. Cov txheej txheej tshwm sim yog kev sib xyaw ntawm zinc thiab hlau. Nws yog qhov zoo rau kev tsim khoom lossis vuam, tab sis tsis yog qhov kev xaiv zoo tshaj plaws rau kev tsim kho vaj tse uas xav tau cov ntaub ntawv muaj zog thiab kev tiv thaiv corrosion.
Pre-galvanized
Raws li lub npe qhia, pre-galvanizing zoo ib yam li kub-dip galvanizing, tab sis yog ua tiav raws li thawj theem ntawm ntau lawm ntau dua li qhov kawg. Feem ntau yog siv rau cov txheej txheem ceev ntawm cov ntawv hlau, cov khoom siv yog ntxuav thiab kho ua ntej dhau los ntawm cov zinc molten da dej thiab tom qab ntawd rov qab tam sim ntawd. Thaum cov txheej txheem nrawm no ua cov khoom siv, cov txheej txheem tiv thaiv raug txiav thaum lub sijhawm tsim khoom. Qhov no tawm hauv txhua qhov chaw uas qhov kev txiav tshwm sim tsis muaj coated thiab ua rau xeb thiab corrosion.
Yog vim li cas peb tseem pom zoo kom kub dip galvanizing piv rau lwm txoj kev:
Kub-dip galvanizing guarantees pom kev tiv thaiv corrosion
Kub dip galvanizing tseem yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv corrosion qhov kawg. Qhov no yog vim lub thickness ntawm txheej thiab yuav siv sij hawm ntev npaum li cas los thov lub txheej.
Lwm txoj hauv kev galvanizing tsis tso cai rau cov hlau sib txuas nrog zinc zoo ib yam. Qhov no txhais tau hais tias cov txheej txheej tshwm sim tsis yog tuab lossis muaj zog li uas ua los ntawm kub-dip galvanizing. Tsis muaj qhov tuab txaus los tiv thaiv cov khoom siv, cov txheej yuav zoo li tsis yooj yim thiab tsis tuaj yeem tiv taus qhov kev sim ntawm lub sijhawm raws li lwm yam kev xaiv tiv thaiv.
Lwm qhov laj thawj tseem ceeb yog vim li cas kub-dip galvanizing muaj kev tiv thaiv corrosion zoo dua yog tias cov txheej txheem siv thaum lub sij hawm tsim cov txheej txheem ua ntej cov hlau raug ntsia. Qhov no txhais tau hais tias txhua qhov chaw uas raug txiav lossis puas thaum lub sijhawm teeb tsa yuav tseem muaj cov txheej txheem tiv thaiv. Lwm txoj hauv kev galvanizing, xws li pre-galvanizing, coated steel ua ntej txiav thiab fabricated. Qhov no tawm txhua qhov chaw uas raug txiav los yog puas thaum lub sij hawm installation raug xeb thiab corrosion.
Kub dip galvanizing yog kev lag luam ntau dua hauv lub sijhawm ntev
Kub dip galvanizing yog ib txoj hauv kev zoo tshaj plaws ntawm kev tiv thaiv hlau. Muaj ob peb lub laj thawj rau qhov no. Los ntawm galvanizing cov hlau thaum lub sij hawm los yog tom qab fabrication, koj txuag lub sij hawm shipping cov ntaub ntawv rov qab. Koj tau txais cov khoom npaj los txiav yam tsis muaj kev txhawj xeeb txog kev cuam tshuam txog kev ncaj ncees ntawm cov khoom.
