Hauv kev lag luam hlau, kev tswj hwm kev ua tau zoo tshaj plaws thaum lub sijhawm ua cov hlau pickling yog qhov tseem ceeb rau kev tshem tawm cov nplai oxide thiab cov xim kub, kom ntseeg tau tias cov khoom siv hlau stainless zoo. Txawm li cas los xij, cov txheej txheem ua cov hlau pickling ib txwm muaj, vam khom kev kho tshuaj xws li hydrochloric (HCl) lossis sulfuric acid, feem ntau raug kev txom nyem los ntawm cov txiaj ntsig tsis sib xws vim yog cov kua qaub tsis zoo thiab tsis muaj kev saib xyuas lub sijhawm tiag tiag. Qhov no ua rau muaj kev tsis ua haujlwm zoo, cov nqi tsis lees txais siab, thiab cov teeb meem EPA kim heev.
Lonnmeterinline acid density meteryog ib qho kev hloov pauv kev ua si uas siv cov thev naus laus zis ultrasonic rau kev txuas ntxiv musKev ntsuas qhov ceev ntawm cov kua qaub hauv onlineTsim los rau cov chaw ua hlau pickling thiab cov kws kho tshuab, lub ntsuas acid density inline no muaj kev ua haujlwm tsis muaj drift, cov khoom siv tiv taus acid, thiab kev sib koom ua ke tsis muaj kev siv tshuab. Nws yog ib kauj ruam tseem ceeb hauv kev txhim kho qhov zoo thiab kev ua haujlwm zoo rau cov tuam txhab tsim hlau, cov chaw ua hlau tsis yog ferrous, cov chaw tsim khoom bearing thiab fastener, cov chaw tsim khoom electroplating, cov kab ntau lawm anodizing, cov chaw tsim khoom wafer, cov chaw tsim khoom luam tawm Circuit Board (PCB), cov chaw tsim khoom siv tshuaj lom neeg, cov chaw rov ua dua tshiab thiab rov ua dua tshiab hlau.
Kev Paub Txog Kev Siv Tshuab
Txawm hais tias passivation ua rau cov khoom tsis xeb ntawm cov hlau tsis xeb zoo dua, nws tsis daws tau qee qhov tsis zoo ntawm kev tsim khoom. Piv txwv li, nws tsis tshem tawm cov xim kub lossis cov nplai oxide uas tshwm sim los ntawm kev vuam thiab kev kho cua sov. Keeb kwm, cov teeb meem no tau daws los ntawm cov txheej txheem tshuaj ntxiv hu ua "pickling."
Yuav Ua Li Cas Stainless Steel Pickling Ua Haujlwm
Kev ntxuav ua ntej siv cov tshuaj passivation, qhov twg cov khoom siv hlau tsis xeb raug muab tso rau hauv cov kua qaub - feem ntau yog hydrochloric lossis sulfuric acid - kom yaj cov nplai oxide, ua kom sov xim, thiab cov khoom siv hlau uas nkag mus rau hauv. Txawm li cas los xij, cov txheej txheem ntxuav hlau no tsis meej, ua rau muaj teeb meem xws li cov cai nruj ntawm EPA thiab cov txiaj ntsig tsis sib xws. Thaum cov kua qaub laus zuj zus, nws cov txiaj ntsig txo qis, thiab qhov dav ntawm kev tshem tawm cov khoom tuaj yeem sib txawv ntau, ua rau muaj kev nyuaj rau kev tswj hwm qhov zoo sib xws hauv cov txheej txheem ntxuav hlau.
Cov Teeb Meem Tseem Ceeb hauv Kev Saib Xyuas Chav Dej Pickling Inline
Kev soj ntsuam hauv chav dej pickling yog ib qho tseem ceeb ntawmcov txheej txheem pickling hlau, txawm li cas los xij nws muaj ntau qhov mob uas tuaj yeem cuam tshuam kev ua haujlwm thiab qhov zoo hauvCov txheej txheem pickling hlau thiab cov txheej txheem pickling HCLIb qho teeb meem loj yog qhov tsis muaj cov ntaub ntawv tiag tiag, vim tias cov txheej txheem ib txwm muaj xws li kev kuaj tes thiab kev tshuaj xyuas hauv chaw kuaj offline (piv txwv li, titration) ua rau muaj kev ncua sijhawm ntawm 10-30 feeb. Qhov kev ncua sijhawm no feem ntau ua rau muaj kev sib xyaw ntau dhau, ua rau hydrogen embrittlement hauv cov hlau muaj zog siab, lossis tsis sib xyaw ntau dhau, ua rau cov oxide scale tsis hloov pauv thiab ua rau cov nqi tsis lees txais nce mus txog 15%.
Lwm qhov teeb meem tseem ceeb yog qhov kev puas tsuaj ntawm cov kua qaub thaum lub sijhawm dhau mus. Qhov xwm txheej corrosive ntawm cov chaw da dej pickling kuj ua rau muaj kev pheej hmoo rau cov khoom siv saib xyuas, nrog rau cov sensors ib txwm muaj xws li cov iav ntom ntom meters succumbing rau kev puas tsuaj, yuav tsum tau hloov pauv thiab txij nkawm ntau zaus, uas yuav ua rau tus nqi nce ntxiv hauvcov txheej txheem tshuaj lom neeg picklingtxhiab xyoo.
Kev ua raws li ib puag ncig ntxiv qhov nyuaj ntxiv, vim tias EPA cov cai xav tau kev tswj hwm nruj ntawm cov pa roj acid thiab pov tseg. Kev saib xyuas tsis raug tuaj yeem ua rau muaj kev ua txhaum cai, raug nplua thiab ua rau kev kho cov kua qaub pov tseg nyuaj. Tsis tas li ntawd, qhov sib txawv ntawm kev tshem tawm cov khoom ua rau nws nyuaj rau ua tiav qhov zoo sib xws. Kev daws cov teeb meem mob no xav tau kev daws teeb meem zoo lionline acid density meterkom ntseeg tau tias muaj kev ua tiav thiab kev ruaj khov ntawm cov txheej txheem.
Cov txiaj ntsig ntawm kev qhia txog Inline Acid Density Meter
Kev Hloov Pauv Kev Ua Haujlwm Zoo thiab Kev Ua Tau Zoo hauv Kev Ua Kua Txob
Kev qhia txog lub ntsuas qhov ceev ntawm cov kua qaub hauv kab, xws li Lonnmeter cov kev daws teeb meem siab heev, ua rau muaj kev hloov pauv ntawm cov txheej txheem pickling hlau los ntawm kev muab kev ntsuas qhov ceev ntawm cov kua qaub hauv online. Cov thev naus laus zis no ua kom cov kua qaub nyob hauv qhov ntau thiab tsawg zoo tshaj plaws, tiv thaiv kev pickling ntau dhau uas tuaj yeem ua rau hydrogen embrittlement lossis under-pickling uas ua rau cov oxide scale tseem zoo. Los ntawm kev saib xyuas qhov hloov pauv ntawm qhov ceev uas tshwm sim los ntawm cov hlau ion sib sau ua ke, lub ntsuas ua rau muaj kev hloov kho tsis siv neeg.
Kev Txuag Nyiaj thiab Kev Ntseeg Siab Hauv Kev Ua Haujlwm
Kev siv lub ntsuas acid density inline muab cov txiaj ntsig zoo rau tus nqi, txo kev siv hluav taws xob. Los ntawm kev sib koom ua ke nrog PLC/DCS systems ntawm 4-20 mA lossis RS485 outputs, lub ntsuas no ua rau kev rov ua kom acid rov qab thiab kev tswj cov khib nyiab tsis siv neeg.
Kev Ua Raws Cai Ib puag ncig thiab Kev Siv Tau Ntau Yam
Lub ntsuas qhov ceev ntawm cov kua qaub hauv online txhawb nqa kev ua raws li ib puag ncig los ntawm kev tswj cov kua qaub hauv qab EPA cov kev txwv, zam kev nplua thiab ua kom yooj yim rau kev kho cov kua qaub pov tseg. Nws qhov kev ua tau ntau yam nthuav dav mus rau cov txheej txheem ua pawg, qhov twg nws ntsuas qhov kev poob kua qaub tom qab lub voj voog, thiab cov txheej txheem kho cov khib nyiab.
Kev Tswj Xyuas Txheej Txheem Zoo Dua thiab Kev Npaj Txhij Yav Tom Ntej
Tsis tas li ntawm qhov tau txais tam sim ntawd, lub ntsuas qhov ceev ntawm cov kua qaub hauv kab ua rau muaj kev tswj hwm cov txheej txheem los ntawm kev ntes cov qauv hauv cov ntaub ntawv ceev, tso cai rau cov kws kho tshuab kom kwv yees qhov kev puas tsuaj ntawm cov kua qaub lossis cov teeb meem khoom siv ua ntej lawv nce siab. Kev koom ua ke nrog kev ua haujlwm tsis siv neeg, nws txo cov kev cuam tshuam tes, tso cai rau cov neeg ua haujlwm tsom mus rau cov haujlwm tseem ceeb. Rau cov chaw tsim khoom siv hlau uas xav txog yav tom ntej, cov thev naus laus zis no txhawb nqa kev hloov kho OEM / ODM thiab kev koom tes R & D, kom ntseeg tau tias muaj kev nkag mus rau cov kev tsim kho tshiab.
