Cov txheej txheem sib txawv ntawm cov hlau stainless welded feem ntau pleading, Cov nto feem ntau ua rau cov xim dub oxide. Oxide nplai tsis tsuas yog cuam tshuam rau cov tsos zoo ntawm stainless hlau, tab sis kuj cuam tshuam rau kev ua cov khoom tom ntej. Yog li no, txoj kev kho deg ua xws li pickling, passivation, thiab polishing yuav tsum tau siv kom tshem tawm lawv nyob rau hauv tom ntej pretricalment ntawm electrastment. Raws li cov kws tshaj lij kev tsim khoom ntawm cov yeeb nkab ua tshuab ua, Hangao Tech (Seko Machinery) mob siab rau peb tus kheej los daws cov neeg siv khoom. Cia peb nrhiav
cov teeb meem txog cov yeeb nkab steel hlau polishing.
Kev ua polishing suav nrog cov neeg kho tshuab polishing, tshuaj lom neeg polishing, thiab electrochemical polishing. Batch xov xwm yog siv cov abrasive nyob rau hauv cov polishing tus neeg sawv cev rau txhuam ntawm ib feem kom du rau saum npoo thiab ua tiav cov txiaj ntsig polishing. Tom qab polishing, tsom iav saum npoo nrog qhov chaw ntawm 0.4um lossis tsawg dua tuaj yeem tau txais. Qhov nrog cov duab yooj yim tuaj yeem ua polished nrog nyuaj polishing log lossis cov siv tawv, thiab qhov nrog cov nyom polishing. Cov pob loj ntawm qhov chaw me me yog dai kom zoo nkauj hauv cov pob. Muaj cov hau kev xws li cov menyuam dov, vibrating lub tshuab vibrating teeb, centrifuge centrifugal teeb, thiab tig lub teeb. Neeg kho tshuab polishing muaj ib qho me me ntawm kev sib tsoo nto, thiab nws yog qhov nyuaj rau cov nplaim ntxhib.
Nyob rau lub sijhawm no, nws yuav tsum tau polished ua ntej, nrog lub log polishing thiab lub cev polishing rau sib tsoo, uas tau muab faib ua kev sib tsoo, sib tsoo nruab nrab thiab sib tsoo kom sib tsoo. Tom qab sib tsoo zoo, lub npoo roughness tuaj yeem ncav cuag 0.4um. Txhawm rau kom tau raws li lwm yam yuav tsum tau ua, xws li descaling, kev kho kom zoo nkauj xws li sandblasting, thiab txhuam hniav nrog steel hlau log tau siv. Qhov saum npoo polished nrog stainless hlau xaim yuav ua tau zoo zam dhau cov pa phem. Xav txog qhov txawv kev thov ntawm polishing degree, peb muaj ntau txoj kev xaiv ntawm cov qauv sib txawv, zoo li 8 lub taub hau polishing taub hau sib tsoo tshuab , 10 lub taub hau, 16 taub hau thiab 32 lub taub hau, rau puag ncig thiab sib dhos hlab. Tshuaj lom neeg polishing yog kom paub cov seem nyob rau hauv cov kev daws teeb meem Feem ntau hais lus, tshuaj lom neeg polishing tsis zoo polishing muaj peev xwm thiab tsuas yog txhim kho qhov ci ci los ntawm ib qho me me. Tab sis nws yog kev txuag zog-txuag thiab txuag dua li cov tshuab Polishing, thiab nws tuaj yeem txhuam sab hauv qhov chaw me me.
Tsis ntev los no, nws tseem tau tshaj tawm tias lub sijhawm ntawm 18-8 hom anustenitic stainless hlau tuaj yeem polished rau daim iav ci ci los ntawm kev ua kom muaj qhov muag. Tab sis them sai sai rau cov ntsiab lus hauv qab no.
(1) Cov chaw ua haujlwm nquag yog tsim tawm tom qab tshuaj lom neeg polishing, thiab cov haujlwm ua haujlwm yuav tsum yog passivated kom ntseeg tau corrosion tsis kam.
(2) Rau cov khoom loj xws li nkhaus thiab scrackets thiab screws, tshuab stirring yuav tsum tau siv los ua kom cov khaub ncaws polishing.
(3) Thaum polishing loj-thaj chaw ntawm cov hlau stainless sib xyaw ua ke thiab lwm cov khoom lag luam, tau them nyiaj tshwj xeeb tom qab polishing los tiv thaiv kev ci ntsa iab tsis zoo. Electrochemical polishing tuaj yeem txhim kho kev ua tau zoo ntawm seem; txhim kho corrosion tsis kam; txo cov npoo tawv ntawm cov txheej txheem; thiab txo cov kev txhuam hniav sib txhuam vim qhov txo ntawm qhov chaw mos. Electrochemical polishing kuj tseem siv tau los tshem tawm burrs thiab li ntawd.
Piv nrog kho tshuab polishing, electrochemical polishing muaj cov cwj pwm hauv qab no.
(1) Cov neeg kho tshuab polishing yuav tsim cov txheej txheem hardened thiab abrasive suav nrog cov stainless hlau, uas yuav ua rau corrosion tsis kam ntawm stainless hlau.
(2) electrochemical polishing muaj qee yam yuav tsum muaj rau substrate. Piv txwv li, thaum tus qauv kab hlau tsis zoo li qub, nws yuav tsim ib qho tsis sib xws sab nrauv, thiab kev sib sib zog nqus tsis tau polished. Cov neeg kho tshuab polishing muaj ntau dua qhov yuav tsum tau ua ntawm substrate.
(3) Rau qhov chaw nrog cov duab ua ke, cov xov hlau, nyias daim hlau thiab cov khoom qub, electrochemical polishing yog qhov yooj yim dua li kho tshuab polishing.
(4) Kev tsim khoom ntawm electrochemical polishing yog siab dua li ntawm cov neeg kho tshuab polishing, tab sis loj loj tam sim no, uas ua rau nws nyuaj los ua electrochemical polishing.
(5) Cov nplaim hluav taws xob ntom ntom ntom ntom ntom nti ntawm electrochemically polished workpiece yuav tsum yog khaub ncaws, thiab yog tias tsim nyog, ib qho kev ci ntsa iab pictograph, txwv tsis pub sab saum npoo ci yuav tsis sib luag.
(6) Qhov tam sim no tseem ceeb thaum hluav taws xob puv ib ce, thiab cov ua haujlwm kom muaj qhov chaw tiv toj thiab kev sib cuag zoo li no yuav hlawv cov workpiece.
(7) Ib co txheej txheem polishing siv rau kev siv tshuaj rau cov hlau tsis tuaj yeem siv rau kev polishing martensitic stainless hlau, uas yog nquag rau corrosion.
