Kev sib piv ntawm ob txoj kev polishing rau kev ua cov hlau stainless Chemical polishing rau kev ua cov hlau stainless yog ib txoj hauv kev ntawm kev tshem tawm cov cim, etching thiab leveling los ntawm kev xaiv dissolving qhov tsis sib xws ntawm qhov chaw ntawm cov qauv los ntawm cov tshuaj reagents.
Electrochemical muaj peev xwm ntawm cov txheej txheem nyob rau saum npoo ntawm cov qauv hlau yog txawv, thiab ntau micro-potentials raug tsim, uas yuav ua rau tsis sib npaug ntawm cov tshuaj tov. Thaum lub sij hawm dissolution txheej txheem, ib txheej ntawm oxide zaj duab xis yuav raug tsim nyob rau saum npoo ntawm cov qauv nto. Vim lub nyias mucous daim nyias nyias ntawm lub protruding ib feem ntawm cov qauv nto, lub dissolution thiab expansion ceev ntawm hlau yog kuj qeeb. kev xav tau zoo tagnrho. Thaum pom nrog lub tshuab ntsuas qhov ntsuas qis thiab nruab nrab, qhov kev hloov pauv me me no feem ntau nyob rau hauv txoj kev sib cais ntsug ntawm lub hom phiaj lens, thiab qhov pom tseeb ntawm histochemical polishing tseem tuaj yeem pom. Kauj Ruam 1: Kev npaj ua qauv: Cov qauv yog finely hauv av Tom qab ntxuav. 2: Configure tshuaj polishing tov.
Cov tshuaj polishing tov rau stainless hlau qhov chaw ua yuav tsum tau npaj nyob rau hauv ib tug beaker. Cov tshuaj polishing tov mis yuav tsum raug xaiv raws li cov qauv khoom. Cov dej distilled yuav tsum tau siv thaum npaj cov tshuaj, thiab cov tshuaj ntshiab reagents yuav tsum tau siv rau cov kws tshuaj.
Qee cov tshuaj uas tsis yooj yim soluble hauv dej yuav tsum tau cua sov ntawm cov tshuaj kom yaj. Hydrogen peroxide thiab hydrofluoric acid yog corrosive heev, yog li xyuam xim rau kev nyab xeeb thaum npaj lawv. Tom qab siv cov tshuaj txhuam polishing, cov hlau ions hauv cov tshuaj nce ntxiv, thiab cov nyhuv polishing tsis muaj zog. Yog tias pom tias cov nyhuv qeeb thiab cov pa npuas yuav raug txo, cov tshuaj tshiab yuav tsum tau hloov. 3: Cov qauv yog immersed nyob rau hauv polishing tov nrog xyoob clips los yog ntoo clips, thiab nws yog stirred thiab coj tawm nyob rau hauv lub sij hawm los soj ntsuam kom txog rau thaum lub polishing yuav tsum tau ntsib. 4: Tom qab tshuaj txhuam hniav, cov qauv yuav tsum tau ntxuav thiab qhuav tam sim ntawd. Disadvantages ntawm tshuaj polishing 1. Qhov zoo ntawm cov tshuaj polishing tsis zoo li cov electrolytic polishing. 2. Nws yog qhov nyuaj rau kev kho thiab rov tsim cov tshuaj siv tshuaj polishing, thiab nws daim ntawv thov raug txwv. 3. Thaum lub sijhawm ua haujlwm tshuaj polishing, nitric acid emits ib tug loj npaum li cas ntawm daj-xim av teeb meem roj, uas yog heev hnyav rau ib puag ncig muaj kuab paug.
Lub electrochemical polishing ntawm stainless hlau qhov chaw yog sib tsoo thiab polishing siv lub hauv paus ntsiab lus ntawm hlau electrochemical anode dissolution. Lub electrochemical pre-polishing thiab mechanical fine polishing yog organically ua ke, thiab ob hom polishing yam ntxwv ntawm electrochemical thiab mechanism yog coj los ua si.
Nws tsis yog txwv los ntawm hardness thiab toughness ntawm cov khoom, thiab tuaj yeem polish workpieces ntawm ntau yam duab. Txoj kev zoo ib yam li electrolytic sib tsoo. Qhov zoo: Cov txheej txheem stainless hlau yog ntau daim iav zoo li
