Electrogalvanizing VS. Kub-dip Galvanizing
Raws li kev txheeb cais, steel yog ib qho yooj yim rau xeb hauv huab cua, dej lossis av, thiab kev poob txhua xyoo los ntawm kev xeb nyiaj txog li 1/10 ntawm tag nrho cov hlau tsim. Txhawm rau ua kom lub ntsej muag fasteners muaj qee qhov tshwj xeeb ua haujlwm thiab muab lawv lub ntsej muag zoo nkauj, feem ntau yog kho los ntawm electrogalvanizing.
Electrogalvanizing
Electrogalvanizing yog txheej txheem uas siv zinc txheej rau hlau lossis hlau los ntawm kev siv hluav taws xob tam sim no. Lub hauv paus ntsiab lus suav nrog immersing ib feem kom coated rau hauv cov tshuaj uas muaj zinc ions. Thaum cov hluav taws xob tam sim no dhau los ntawm electrolyte, zinc ions raug txo rau ntawm qhov chaw ntawm cathode, tso ib txheej nyias ntawm cov zinc ntshiab. Lub thickness thiab uniformity ntawm cov txheej yuav raug tswj tau los ntawm kev kho lub sijhawm ntawm cov txheej txheem, qhov ceev tam sim no, thiab cov muaj pes tsawg leeg ntawm cov electrolyte. Txoj kev no tso cai rau lub teeb ci, du, thiab zoo nkauj ua tiav, nrog cov txheej txheem feem ntau ntawm 5 txog 30 micrometers.
Cov yam ntxwv ntawm kev ua haujlwm ntawm electrogalvanized txheej muaj xws li zoo heev adhesion rau lub hauv paus hlau, muab zoo corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv tsis tshua muaj aggression ib puag ncig. Cov tuab tuab thiab tswj tau ua kom zoo ib yam, ua rau nws zoo tagnrho rau qhov chaw uas yuav tsum tau ua tiav zoo. Txawm li cas los xij, cov txheej txheej nyias nyias txhais tau hais tias electrogalvanizing yuav tsis muab tib theem ntawm kev tiv thaiv kev tiv thaiv ib yam li kub-dip galvanizing, thiab nws yuav ua rau muaj kev puas tsuaj ntau dua los ntawm kev puas tsuaj thiab cuam tshuam. Txawm li cas los xij, cov txheej txheem no paub txog nws lub peev xwm los tsim kev nplua, txawm tias txheej txheej uas txhim kho qhov pom kev pom ntawm cov khoom tiav.
Cov teb koom nrog hauv electrogalvanizing tau dhau los ua ntau thiab ntau dua. Daim ntawv thov ntawm cov khoom fastener tau kis mus rau machinery manufacturing, electronics, precision instruments, tshuaj, tsheb thauj mus los, aerospace, thiab lwm yam., uas yog ib qho tseem ceeb nyob rau hauv lub teb chaws kev khwv nyiaj txiag.
Kub-dip galvanizing
Kub-dip galvanizing yog txheej txheem kev tiv thaiv corrosion uas ntxuav thiab npaj cov hlau lossis hlau cov khoom siv rau hauv da dej ntawm zinc molten ntawm kwv yees li 450 ° C (842 ° F). Zinc reacts nrog hlau, tsim ib tug series ntawm zinc-hlau alloy txheej nyob rau saum npoo ntawm cov hlau, ua raws li los ntawm ib tug txheej ntawm ntshiab zinc. Qhov no metallurgical daim ntawv cog lus tsim ib tug ruaj thiab nruj adhered txheej. Lub thickness ntawm zinc txheej yog tswj nws tus kheej thiab feem ntau yog nyob ntawm 45 txog 275 micrometers, nyob ntawm seb lub thickness ntawm cov khoom siv hauv paus. Lub sijhawm immersion thiab qhov txias txias tom qab tshem tawm ntawm lub da dej tuaj yeem cuam tshuam cov tsos thiab kev ntxhib los mos ntawm txheej txheej kawg, feem ntau ua rau tus yam ntxwv spangled lossis crystalline qauv.
Cov yam ntxwv ntawm kev ua haujlwm kub-dip galvanized coatings suav nrog kev ua haujlwm tshwj xeeb thiab kev ua haujlwm ntev corrosion, uas tuaj yeem kav ntev mus rau ntau xyoo txawm nyob rau hauv qhov chaw hnyav. Cov txheej zinc tuab muab kev tiv thaiv zoo tiv thaiv kev puas tsuaj, xws li khawb thiab abrasions, thiab ua raws li kev txi anode, corroding nyiam los tiv thaiv cov hlau hauv qab. Cov txheej kuj muaj qhov kub thiab txias, txawm tias nws yuav cuam tshuam los ntawm qhov kub thiab txias heev. Thawj lub ci ci, xim hlau grey tsos ntawm cov txheej yuav huab cua dhau sijhawm mus rau matte grey patina, uas tsis cuam tshuam nws cov khoom tiv thaiv. Tsis tas li ntawd, cov txheej txheem yog tus nqi-zoo rau cov khoom loj thiab hnyav, raws li nws muab cov kev daws teeb meem ntev uas yuav tsum tau muaj kev saib xyuas tsawg.
Kub-dip galvanizing yog dav siv nyob rau hauv ntau yam kev siv, tshwj xeeb tshaj yog cov uas muaj nyob rau hauv sab nraum zoov qauv thiab infrastructure, qhov twg raug rau cov ntsiab lus tseem ceeb. Nws yog feem ntau siv rau cov qauv hlau, txuas hniav, txoj kev loj guardrails, cov khoom siv hluav taws xob, thiab lwm yam khoom siv. Cov txheej txheem kuj tseem nrov hauv kev tsim cov khoom siv ua liaj ua teb, kev siv tshuab, thiab kev thauj mus los, suav nrog kev tsheb ciav hlau thiab cov thawv thauj khoom. Vim nws lub peev xwm los muab qhov muaj zog, ruaj khov, thiab ua kom zoo nkauj tiav, kub-dip galvanizing yog qhov kev xaiv zoo tshaj plaws rau txhua daim ntawv thov uas xav tau kev tiv thaiv ntev thiab kev tiv thaiv corrosion.
