Electroplating thiab polishing txheej txheem, ob txoj kev kho saum npoo siv ua ke tsis muaj teeb meem, tab sis kuj muaj ntau heev; Yog li dab tsi yog cov yam ntxwv thiab cov ntsiab lus ntawm txhua txoj kev?

Polishing: daim iav stainless hlau phaj yog los ntawm kev siv tshuab, tshuaj lossis electrochemical polishing txheej txheem, qhov roughness ntawm stainless hlau substrate txo qis heev, thiaj li hais tias qhov saum npoo ntawm lub substrate yuav ci, tiaj tus, nto ntawm BA, 2B, No.1 stainless hlau ua rau zoo ib yam li daim iav nto. 8k i 10k.

Muaj peb txoj hauv kev polishing:

Tshuab polishing

Qhov zoo: me ntsis siab dua siv zaus, siab brightness, zoo flatness, thiab ua thiab yooj yim, yooj yim ua hauj lwm;

Qhov tsis zoo: ua cov plua plav, tsis zoo rau kev tiv thaiv ib puag ncig, tsis tuaj yeem ua cov txheej txheem nyuaj

Tshuaj polishing

Qhov zoo: kev ua haujlwm siab, ceev ceev, kev ua haujlwm siab ntawm qhov chaw, cov nqi ua haujlwm tsawg

Disadvantages: low brightness ntawm workpiece, hnyav ua ib puag ncig, tsis conducive rau ib puag ncig tiv thaiv

Electrochemical polishing

Qhov zoo: daim iav luster, txheej txheem kev ruaj ntseg, muaj kuab paug tsawg, zoo heev corrosion kuj

Disadvantages: high upfront peev nqi

Electroplating: nws yog kev siv cov electrolysis ua cov hlau nto ntawm txheej txheej txheej txheej hlau hlau kom tiv thaiv corrosion, txhim kho hnav tsis kam, hluav taws xob conductivity, kev cuam tshuam, qhov tseem ceeb tshaj plaws kuj nce kev xaav, peb pom cov khoom siv hlau tsis zoo ntawm cov kub kub, titanium kub, sapphire xiav thiab lwm yam xim.

Stainless hlau xim plating txheej txheem yog raws li nram no: polishing - roj tshem tawm - ua kom - plating - kaw.

Workpiece polishing: tus du thiab ci ntsa iab ntawm lub workpiece yog qhov yuav tsum tau ua ua ntej rau cov zaub ntawm cov xim hlau ci.Rough nto ua rau xim npub thiab tsis sib luag, los yog ntau xim tshwm nyob rau tib lub sij hawm.Polishing tuaj yeem ua tau mechanically lossis chemically.

Kev tshem tawm roj: kev tshem tawm cov roj yog ib qho tseem ceeb kom ntseeg tau tias cov xim zoo sib xws thiab ci xim txheej. Cov txheej txheem tshuaj thiab electrolytic tuaj yeem siv.Yog siv tshuaj polishing, tshem cov roj ua ntej polishing.

Kev ua kom muaj zog: kev ua kom muaj zog yog ib qho tseem ceeb rau qhov zoo ntawm stainless hlau xim txheej.Qhov saum npoo ntawm stainless hlau yog ib qho yooj yim rau passivation, passivation rau saum npoo yog nyuaj rau cov xim txheej los yog txheej tsis zoo ntawm cov hlau tsis zoo.Qhov kev ua kom cov hlau tsis zoo kuj tuaj yeem ua los ntawm cov tshuaj thiab electrochemical hauv kev daws ntawm 30% sulfuric lossis hydrochloric acid.

Electroplating: nyob rau hauv cov ntsev tov uas muaj pre-kub-plated pab pawg neeg, lub hauv paus hlau ntawm cov plated pab pawg neeg yog siv raws li cathode, thiab cov cations ntawm pre-kub-plated pawg yog tso rau saum npoo ntawm lub hauv paus hlau los ntawm electrolysis.Qhov no yog los txhim kho lub durability ntawm xim txheej thiab tiv thaiv kom txhob kis kab mob, yog ib qho indispensable kauj ruam siv.
