Fasteners yog cov khoom siv feem ntau hauv cov cuab yeej siv tshuab, thiab lawv txoj haujlwm tseem ceeb heev.Txawm li cas los xij, corrosion ntawm fasteners thaum siv yog qhov tshwm sim tshaj plaws.Yuav kom tiv thaiv corrosion ntawm fasteners thaum siv, ntau manufacturers yuav cojkho saum npooTom qab kev tsim khoom, txoj kev kho saum npoo twg tuaj yeem txhim kho cov fasteners los tiv thaiv corrosion tshwm sim?Muaj plaub txoj kev kho saum npoo tseem ceeb los tiv thaiv corrosion ntawm fasteners.
1. electroplating
Electroplating txheej txheem qhov chaw, txoj kev no yog muab cov txheej txheem rau hauv cov hlau tov, thiab tom qab ntawd cia cov txheej txheem txheej txheem npog nrog txheej txheej hlau los ntawm tam sim no, muaj ntau yam cuam tshuam rau txheej txheej hlau, piv txwv li, peb tuaj yeem ua raws li qee lub luag haujlwm sib txawv los xaiv qee cov txheej txheem sib txawv.Feem ntau hlau fasteners yog tiv thaiv corrosion los ntawm galvanizing.
2. Kev kho cua sov
Siv cov kev kho cua sov ntawm cov qauv, muaj qee qhov qauv, piv txwv li, cov laum screws yuav tsum muaj txheej txheej nyuaj.Yog li ntawd, tus kheej-drilling screws tuaj yeem raug kho kom sov kom ntseeg tau tias cov laum screws muaj qhov nyuaj txaus.
3.mechanical plating
Cov neeg kho tshuab plating ntawm tus qauv qhov chaw tso cai rau cov hlau hais kom txias-welded rau cov qauv qhov chaw kom ntseeg tau qee qhov cuam tshuam ntawm cov qauv.Mechanical plating thiab electroplating yog qhov zoo sib xws, tshwj tsis yog tias peb siv ntau txoj kev.Qhov tshwm sim tuaj yeem hais tau zoo ib yam.
4. qhov nto passivation
Rau passivation ntawm tus qauv qhov chaw, passivation tsuas yog muaj ob txoj haujlwm.Ib qho yog txhawm rau ntxiv dag zog ntawm cov qauv txheej txheem, thiab lwm qhov yog ua kom cov oxidation ntawm cov qauv kev txo qis heev.
Peb tuaj yeem xaiv txoj kev kho kom zoo tshaj plaws raws li qhov xav tau tshwj xeeb.Ua li no, lub fastener tuaj yeem ua lub luag haujlwm zoo dua hauv kev siv.
