# Fermentation Heating Tube Anti-Corrosion Cross-Medium Switching Operation Standard Specification ## Preface Cov lus qhia no txhawb nqa tag nrho cov ntaub ntawv tiv thaiv-corrosion system los ntawm Doc.33 mus rau Doc.110. Nws standardizes tag nrho cov txheej txheem kev khiav hauj lwm, tu cov qauv kev pov thawj, kev tiv thaiv kev pheej hmoo thiab cov ntaub ntawv yuav tsum tau thaum fermentation ntau lawm keyboards ntawm txawv corrosive media. Nws tshem tawm cov kab mob hla -ion contamination, galvanic corrosion thiab ceev tube phab ntsa etching tshwm sim los ntawm kev tu cov kav dej tsis tiav thaum lub sij hawm hloov nruab nrab, thiab ua rau kev tswj qhov sib txawv ntawm kev tiv thaiv -corrosion tswj nyob rau hauv nruab nrab kev sib txuas. Media tau muab faib ua peb pawg corrosive rau kev sib txawv ntawm kev hloov pauv: acidic fermentation broth, alkaline kab lis kev cai nruab nrab, thiab siab -chloride raw khoom kua. Kev hloov ncaj qha ntawm ob pawg sib txawv yog txwv tsis pub ua tiav kev sib cais thiab ntau- theem rinsing. Lub hauv paus tseem ceeb ntawm kev hloov pauv tsis zoo yog nyob rau hauv qhov seem ion sib xyaw hauv cov cua sov raj, uas tsim cov tshuaj corrosive composite thiab accelerates pitting corrosion ntawm stainless hlau, txheej txheej ntawm PFA raj, thiab nto yaig ntawm titanium raj. Ua kom tiav kev hloov pauv cov kauj ruam ua haujlwm yog formulated uniformly. Ua ntej, cov neeg ua haujlwm tsim khoom tau txiav tawm cov khoom siv raw khoom nkag thiab nres kev ncig ntawm qhov nruab nrab ntawm cov khoom qub, ua kom tag nrho cov kua seem nyob hauv cov cua sov, txuas cov kav dej thiab cov tso tsheb hlau luam. Thib ob, ua kom cov dej ntws ua ntej tsis pub tsawg tshaj li lub sijhawm teev tseg kom tshem tawm cov khoom seem seem; tso tawm tag nrho cov dej ntws pov tseg kom tiav. Thib peb, xa cov phiaj xwm pickling los yog alkaline neutralization tu raws li cov khoom nruab nrab yav dhau los, tswj cov txheej txheem kev ntsuas kub thiab lub sijhawm kom tshem tawm cov adsorbed biofilm thiab ion residues txuas rau lub raj sab hauv phab ntsa. Plaub, ua ntau qhov kev hloov pauv cov dej ntshiab, thiab coj cov qauv hluav taws xob rau kev kuaj pom ion. Hloov mus rau qhov nruab nrab tshiab tuaj yeem ua tau tsuas yog tom qab kev xeem tau ua raws li cov qauv kev nyab xeeb. Kev tiv thaiv kev tiv thaiv tshwj xeeb yuav tsum tau txais kev pom zoo rau cov kab nruab nrab hloov ntau lawm. Cov ceg kav dej ywj pheej tau teeb tsa rau cov xov xwm sib txawv kom txo qis rov qab ntws tawm zaus; kev sib cais ib ntus qhov muag tsis pom daim hlau raug teeb tsa ntawm cov kav dej sib txuas sib txuas thaum lub sij hawm hloov dua siab tshiab los tiv thaiv qhov nruab nrab rov qab. Kev soj ntsuam xyuas cov khoom tseem ceeb raug kho nyob rau hauv 24 teev tom qab hloov nruab nrab, tsom mus rau qhov txawv txav ntawm qhov kub thiab txias, flange kua seepage thiab raj phab ntsa fogging tshwm sim los ntawm residual ion corrosion. Yog tias pom cov kab etching, txhim kho kev tu kom zoo yuav tsum tau pib tam sim ntawd. Txhua yam kev hloov pauv yuav tsum ua kom tiav - lub sijhawm sau cov ntaub ntawv. Daim ntawv teev npe yuav tsum sau lub sijhawm pib thiab xaus, thawj thiab hom nruab nrab tshiab, lub sijhawm hloov pauv lub voj voog, kev tu tus neeg saib xyuas, cov ntaub ntawv kuaj ion sampling, ntawm - tus neeg teb xov tooj kos npe thiab saib xyuas cov txiaj ntsig tsis zoo. Cov ntaub ntawv kuaj xyuas tsis tsim nyog yuav tsum ua rau cov kav dej txuas ntxiv tu, thiab tag nrho cov txheej txheem rov ua haujlwm tseem raug kaw raws li cov ntaub ntawv tseem ceeb ntawm kev pheej hmoo. Kev txheeb xyuas txhua hli suav nrog kev txhim kho corrosion ntau zaus thiab kev saib xyuas tus nqi hloov pauv ntawm cov chaw ua haujlwm nruab nrab hloov pauv ntau zaus. Yog tias rov ua dua - muaj kev pheej hmoo kis kab mob vim muaj cov txheej txheem hloov pauv tsis tsim nyog, cov txheej txheem sib txuas yuav raug hloov kho hauv lub rooj sib tham xyuas peb lub hlis twg. Tag nrho cov ntaub ntawv hloov pauv nruab nrab, cov ntaub ntawv tshuaj xyuas ion thiab tshaj tawm - hloov cov ntaub ntawv saib xyuas yog dual- thim rov qab thiab khaws cia. Qhov kev qhia tshwj xeeb no tshem tawm cov kev pheej hmoo ntawm kev puas tsuaj los ntawm kev hloov pauv nruab nrab, paub txog tag nrho - txheej txheem tiv thaiv - kev tiv thaiv corrosion npog cov khoom sib txawv, thiab ntxiv txhim kho qhov kaw - voj kev tswj qhov system ntawm fermentation cua sov raj tiv thaiv - corrosion.
