Kev kho saum npoo ntawm cov iav yog ua tiav los txhim kho lub xeev ntawm cov khoom.Feem ntau, muaj kev kho mob dub (nto oxidation), kev kho lubrication khoom, galvanizing, phosphorurative kev kho mob, chemical silver plating, thiab raydent nto kho.Lawv tus yam ntxwv ntawm lawv tus kheej yam ntxwv Cov lus piav qhia yog raws li nram no

1. Kev kho tsaus nti (nto oxidation):

Rau alkaline dub kev kho mob: Thaum muab hlau tso rau hauv ib qho kev kho alkaline tov rau 14ctc, cov hlau nws tus kheej plays ib tug tshuaj nyhuv thiab tsim ib tug dub daim tawv nqaij zaj duab xis ntawm nws nto.Lub thickness ntawm lub cortex dub yog hauv qab no, thiab cov khoom xyaw tshuaj yog plaub-hlau oxidation.Lub cortex muaj cov nyhuv anti-xeb.

2. Khoom lubrication kho:

Tsuas yog txau cov roj nplua nyeem rau saum npoo ntawm lub log hniav ntawm lub iav, thiab cov roj nplua nyeem uas ua raws li qhov chaw kom qhuav los ua daim tawv nqaij.Lub distan sulfide hais muaj nyob rau hauv lubricant cov khoom xyaw nkag mus rau hauv cov ntaub so ntswg hlau los ua ib tug lubrication nyhuv.Tshwj xeeb tshaj yog nyob rau hauv thawj zaug khiav ntawm lub zog los yog tiv thaiv nws cov nyhuv lubrication ntawm micro-kev txav los ntawm kev sib txhuam me me.Feem ntau siv rau hauv qhov chaw uas tsis tuaj yeem siv roj lubricating

3. Galvanized:

Kev kho deg rau lub hom phiaj ntawm kev txhim kho cov kev ua haujlwm tiv thaiv xeb ntawm cov hlau.Nrog rau kev nce qib ntawm rhinate passivation kev kho mob, qhov kev ua tau zoo ntawm kev ua tau zoo kuj tau zoo tuaj.Lub thickness ntawm txheej plating yog txawv, feem ntau txog 225 μm.

4. Kev kho phosphorusization:

Rau kev kho mob phosphate: Hlau yog immersed nyob rau hauv lub cua sov phosphate tov rau tshuaj kho mob, thiaj li hais tias cov hlau nto tsim ib tug phosphate tiv thaiv membrane.Cov tshuaj tiv thaiv xeb ntawm phosphorized cortex muaj kev cuam tshuam zoo thiab cov nyhuv lubrication, yog li nws feem ntau yog siv los kho cov zawv zawg qhov chaw.

5. Tshuaj nyiaj plating:

Cov tshuaj tiv thaiv corrosion ntawm cov tshuaj plating / abrasion kuj yog siab, thiab cov txheej txheem nyiaj-plated tsis dhau hluav taws xob thiab electrolytic.Haum rau cov khoom uas muaj qhov loj me thiab qhov tseeb thiab cov duab nyuaj.

6. Raydent nto kho:

Raydent kev kho mob siv ib txoj kev zoo ib yam li electroplating los tsim 1 ~ 2 μm tuab dub oxidized zoo zoo zaj duab xis rau saum npoo ntawm niam cov khoom.Vim tias daim tawv nqaij zaj duab xis thiab hlau T phau ntawv, nws yog qhov nyuaj heev rau tev tawm.Lub peev xwm xeb kuj muaj zog / hnav-tiv taus muaj peev xwm txhim kho, thiab xim yog xim dub.

Nco tseg:

1. Kev cuam tshuam los ntawm cov duab thiab qhov loj me, lub cortex tsis tuaj yeem tsim tsis sib xws hauv cov hauv paus hniav ntawm cov hniav.

2. Cov xwm txheej sib thooj ntawm ROHS yuav tsum tau qhia meej meej kom paub meej tias kev kho mob ntawm hexagonal chromium yuav tsum tau muab tshem tawm.
