Cov tshuaj pleev xim dub kuj tseem hu ua dub oxide lossis blackening. Nws yog 'conversion txheej', uas yog txheej txheej rau hlau qhov chaw ntawm qhov chaw yog raug rau cov tshuaj o txheej txheem los ntawm cov khoom txheej, hloov nws mus rau hauv cov khoom siv kho kom zoo nkauj lossis cov khoom tiv thaiv.
Tshuaj blackening feem ntau yog siv rau cov fasteners ua los ntawm stainless hlau, tooj liab, tooj liab raws li alloys thiab zinc.
1. Khoom
1. Zaj duab xis niaj hnub thiab zoo, zoo adhesion, abrasion kuj zoo dua li cov khoom siv hauv tsev zoo sib xws. Corrosion tsis kam yog zoo dua li qhov kub kub blackening zaj duab xis.
2. Nrog rau qhov dav ntawm daim ntawv thov, tsis hais lub siab carbon steel, qis carbon steel, alloy steel, silicon steel, manganese steel, suav nrog chromium 12, cam khwb cia hlau tuaj yeem tau txais cov yeeb yaj kiab compact zoo.
3. Lub voj voog luv luv, kev ua haujlwm siab ntau lawm, lub sijhawm blackening tsuas yog xav tau 1 ~ 6min. Kev ua haujlwm yooj yim, cov cuab yeej tsim khoom thiab cov neeg ua haujlwm yuav tsum tsis siab.
4. tuaj yeem ua haujlwm ntawm chav tsev kub, tsis tsim cov pa phem, kev daws teeb meem blackening tsis muaj cov tshuaj corrosive, txhim kho qhov chaw ua haujlwm, kho cov kua uas tsis muaj hlau lead, mercury, chromium, cadmium, arsenic thiab lwm yam hnyav hlau ua paug ntawm ib puag ncig thiab lwm yam organic. cov pa phem.
2. Cov txheej txheem thev naus laus zis
Cov khoom siv hauv paus → Pretreatment → Ntxuav nrog dej → Dub nyob rau hauv chav tsev kub → Ntxuav nrog dej → Qhuav → Dip FQ lub cev qhuav dej antirust roj
