YUAV UA LI CAS YUAV UA LI CAS Kub-dip galvanizing THIABHluav taws xob galvanizing
Kub-dip galvanizing
Kub-dip galvanizing tseem hu ua kub-dip galvanizing thiab kub-dip galvanizing: nws yog ib txoj kev zoo hlau los tiv thaiv corrosion, feem ntau yog siv nyob rau hauv cov hlau qauv chaw nyob rau hauv ntau yam industries. Nws yog txhawm rau txhawm rau txhawm rau xeb tshem tawm cov hlau hauv cov zinc molten ntawm li 500 degree, kom lub ntsej muag ntawm cov hlau yuav txuas nrog zinc txheej, thiaj li ua tiav lub hom phiaj ntawm kev tiv thaiv corrosion.
Hluav taws xob galvanizing
Electro galvanizing yog ib qho kev kho saum npoo uas siv los tiv thaiv cov khoom hlau los ntawm corrosion. Nyob rau hauv cov txheej txheem electrogalvanizing, zinc hlau yog tso rau ntawm cov hlau nto los ntawm cov tshuaj tiv thaiv electrochemical, tsim ib txheej tiv thaiv zinc. Electro-galvanizing tuaj yeem tiv thaiv cov khoom hlau los ntawm kev sib cuag nrog cov pa oxygen, dej thiab lwm yam corrosive nyob rau hauv ib puag ncig, yog li ua rau lawv lub neej ua haujlwm ntev thiab txhim kho corrosion kuj. Electrogalvanizing feem ntau yog siv hauv cov khoom siv hlau xws li cov ntsia hlau, txiv ntseej, cov kav dej, hlau mesh thiab nws pib qhov chaw.
Kev piav qhia
1. Kub-dip galvanizing yog ib txoj kev hlau los tiv thaiv corrosion. Nws feem ntau tso cov qauv hlau kom derusted rau hauv zinc tov ntawm li 500 degree C, kom cov zinc txheej adheres rau saum npoo ntawm steel qauv. Txias galvanizing siv electrolysis los txuas ib txheej ntawm cov yeeb yaj kiab hlau rau saum npoo ntawm cov hlau thiab lwm yam ntaub ntawv, ua rau saum npoo ntawm cov khoom sib xws hauv kev ntxhib los mos, tiv thaiv corrosion thiab hnav-resistant, thiab zoo nkauj dua nyob rau hauv tsos.
2. Cov txheej kub-dip galvanized yog tuab dua, feem ntau 30-60 microns, thiab txheej txheej muaj peev xwm tiv thaiv corrosion ntau dua. Nws yog qhov tsim nyog rau kev tiv thaiv xeb ntev ntev ntawm steel qhov chaw rau kev ua haujlwm sab nraum zoov, xws li cov laj kab kev loj, lub zog yees, qhov loj-loj fasteners thiab lwm yam " ntxhib" workpieces. Txias galvanizing, nto ntawm lub workpiece yog du thiab tiaj tus, tab sis vim hais tias cov txheej yog nyias nyias, feem ntau nyob rau hauv 5-30 microns, lub sij hawm los tiv thaiv corrosion yuav luv luv. Ob leeg yog siv los tiv thaiv xeb ntawm sab hauv tsev, xws li hauv qab ntawm lub txee, panels, thiab me me fasteners.
3. Kub-dip galvanizing siv lub hauv paus ntsiab lus ntawm zinc los tiv thaiv atmospheric corrosion rau electrochemically tiv thaiv hlau thiab lwm yam ntaub ntawv. Zinc carbonate tiv thaiv zaj duab xis rau ntawm qhov chaw tuaj yeem ua kom qeeb ntawm zinc corrosion. Txawm hais tias nws raug rhuav tshem, ib zaj duab xis zinc yuav raug tsim dua. Txias galvanizing siv cov txheej txheem tshuaj los cais cov zinc alloy rau hauv zinc ions, uas tau txuas rau saum npoo ntawm cov hlau. Cov txheej txheem tshiab tsim los ntawm txoj kev no feem ntau yog nyias, thiab cov hlau yog nquag xeb nyob rau hauv ib txwm muaj xwm txheej.
4. Cov txheej txheej ntawm txias-dip galvanizing yog tus du thiab ci. Cov txheej txheem electroplating nrog cov txheej txheem xim passivation yuav tshwm daj-ntsuab, thiab cov txheej txheem electroplating nrog cov txheej txheem dawb passivation yuav tshwm xim dawb. Feem ntau, tsuas muaj me me ntawm zinc txheej ntawm ob qhov kawg ntawm cov yeeb nkab txias-galvanized steel. , thiab tom qab ntawd tsis muaj galvanized txheej sab hauv. Cov txheej txheej ntawm kub-dip galvanized yog qhov ntxhib, xim tsaus, thiab feem ntau silvery dawb, vim tias cov txheej txheem tsim khoom ua rau qee qhov dej thiab poob rau ntawm qhov chaw, thiab qhov saum npoo tsis tawm lub teeb lossis cuam tshuam lub teeb. Kub-dip galvanized steel yeeb nkab muaj ib tug ua tiav galvanized txheej sab hauv thiab sab nraud.
5. Sib txawv ntawm cov txheej txheem
Muaj ntau cov txheej txheem ua rau kub-dip galvanizing. Tom qab lub workpiece degreasing, pickling, dipping, ziab thiab lwm yam txheej txheem, nws muaj peev xwm muab tso rau hauv lub molten zinc da dej, thiab nws yuav tsum tau muab tshem tawm tom qab soaking rau ib lub sij hawm ntawm lub sij hawm. Qhov no yog kub-dip galvanizing. Zoo li qee qhov kub-dip yeeb nkab fittings tau ua tiav hauv txoj kev no. Qhov txias-dip galvanizing yog qhov tseeb electro-galvanizing, uas yog ua los ntawm cov khoom siv electrolytic. Tom qab degreasing, pickling thiab lwm yam txheej txheem, nws yog immersed nyob rau hauv ib qho kev daws uas muaj zinc ntsev, txuas nrog cov khoom siv electrolytic, thiab muab tso rau ntawm lub workpiece thaum lub sij hawm taw qhia ntawm qhov zoo thiab tsis zoo electrodes. Nws los ntawm kev tso nyiaj ntawm zinc txheej.
6. Paub qhov txawv ntawm qhov tsos
Tag nrho cov tsos ntawm kub-dip galvanizing yog me ntsis rougher, thiab nws yuav tsim cov txheej txheem watermarks, dripping qog, thiab lwm yam, tshwj xeeb tshaj yog nyob rau hauv ib kawg ntawm lub workpiece, uas yog silver-dawb tag nrho. Cov txheej txheej ntawm electro-galvanized yog tus du, feem ntau daj-ntsuab, ntawm chav kawm, kuj muaj cov yeeb yuj, xiav-dawb, dawb nrog lub teeb ntsuab, thiab lwm yam. Tag nrho cov workpiece yeej tsis tshwm zinc qog, agglomeration, thiab lwm yam.
