Stainless hlau passivation
Stainless hlau passivation tshuab yog ua kom stainless hlau cuam tshuam nrog oxidizing nruab nrab, feem ntau hnyav hlau ntsev tov los yog nitric acid tov, thiab tsim ib tug passivation zaj duab xis nyob rau saum npoo ntawm stainless hlau nrog me me thickness tab sis tuab heev, kev pab them nqi zoo, thiab yuav ruaj khov. txuas rau ntawm qhov chaw hlau.
Cov tshuaj muaj pes tsawg leeg ntawm cov zaj duab xis passive feem ntau yog hlau oxide, uas tuaj yeem cais cov hlau thiab corrosive nruab nrab, tsis txhob sib cuag ntawm lawv, thiab tiv thaiv hlau corrosion zoo.
Stainless hlau passivation tshuab yog qhov zoo heev los txhim kho kev ruaj ntseg ntawm stainless hlau hauv ib puag ncig xov xwm. Nws tuaj yeem tiv thaiv corrosion hauv zos ntawm stainless hlau. Tsis tas li ntawd xwb, lub tshuab no tseem tuaj yeem ua kom muaj kev huv txaus rau cov hlau tsis huv thiab tshem tawm cov khoom ua haujlwm kub uas tsim los ntawm stainless hlau nto.
Tam sim no, stainless hlau passivation tshuab yog dav siv nyob rau hauv aerospace, mobile kev sib txuas lus, tsom iav, moos, nws pib qhov chaw, precision hardware, kho mob, khoom noj khoom haus machinery, fasteners thiab lwm yam lag luam, rau kev ua stainless hlau fasteners, precision castings, raws li zoo raws li txiav. , stamping, tapping, hlau kos duab, vuam thiab lwm yam khoom siv.
Electrolytic polishing ntawm stainless hlau
Stainless hlau electropolishing tshuab yog ib lub tshuab siv stainless hlau workpiece li anode thiab insoluble hlau li cathode kom ua tiav cov anode dissolution los ntawm qhov mob cov ntsiab lus nyob rau hauv electrolyte, thiaj li ua kom lub workpiece nto tiaj tus thiab kaj.
Nyob rau hauv kev xyaum, muab ob tug ncej rau hauv electrolytic cell tib lub sij hawm thiab siv ncaj qha tam sim no. Lub stainless hlau workpiece ntawm lub anode yuav tsim soluble hlau ions vim poob ntawm electrons. Vim tias cov txheej txheem no feem ntau tshwm sim nyob rau hauv txoj hauj lwm convex ntawm cov hlau nto, nws tuaj yeem ua rau lub workpiece nto tiaj tus. Tom qab cov ion raug cais tawm ntawm qhov chaw ua haujlwm, nws yuav ua ke nrog cov phosphoric acid nyob rau hauv cov electrolyte los tsim ib txheej ntawm phosphate zaj duab xis, uas yog txuas mus rau lub workpiece nto, uas ntxiv tsub kom lub flatness ntawm lub workpiece nto thiab coj ib tug kaj nyhuv. tib lub sijhawm.
Stainless hlau electropolishing tshuab tuaj yeem txhawb qhov nto ntawm stainless hlau workpiece kom zoo ib yam ntawm cov xim, huv si thiab ci, ruaj nyob rau hauv luster, thiab meej nyob rau hauv tsos. Yog hais tias lub workpiece ua tiav nrog cov xov, cov burr hauv cov xov tuaj yeem yaj thiab poob rau hauv cov txheej txheem electrolytic, zoo tiv thaiv qhov tshwm sim ntawm tom ntawm cov xov. Electropolished nto tuaj yeem muaj zog corrosion kuj. Ntxiv mus, piv nrog cov neeg kho tshuab polishing, cov cuab yeej siv tshuaj lom neeg no muaj kev ua haujlwm ntau dua thiab txo cov nqi tsim khoom.
Stainless hlau electropolishing tshuab yog tsuas yog siv nyob rau hauv kev ua thiab tsim ntawm biochemical, tshuaj, tshuaj thiab piping; Kev ua thiab kev tsim khoom noj, dej haus, dej ntshiab thiab cov khoom siv dej huv ultra huv; Thiab kev ua thiab kev tsim cov khoom siv hauv cov tshuaj pleev ib ce thiab ntxhua khaub ncaws khoom lag luam. Tsis tas li ntawd, cov thev naus laus zis no kuj tau ua lub luag haujlwm tseem ceeb hauv kev ua cov khoom siv ultra ntshiab thiab siab nqus thiab nws cov kav dej siv hauv cov txheej txheem semiconductor, thiab cov khoom siv hauv cov xim, txheej, number case ntau lawm kev lag luam thiab luam ntawv thiab dyeing kev lag luam.
