Pickling ntau lawm kab rau electroplating, leaching reactors nyob rau hauv hydrometallurgy thiab brine kho chaw raws ntug hiav txwv dej niaj hnub lis acidic daws loaded nrog chloride ions. Ordinary stainless hlau tsis tuaj yeem muaj sia nyob cov chaw ua haujlwm no. Chloride ions nkag mus rau cov yeeb yaj kiab oxide passive ntawm cov hlau thiab ua rau muaj kev puas tsuaj pitting corrosion. Ua tsaug rau qhov tshwj xeeb los tiv thaiv- cov khoom xeb hauv siab - cov kua qaub acidic, forged titanium immersion heaters tau dhau los ua qhov kev xaiv cua sov uas muaj feem cuam tshuam nrog kev lag luam.
Titanium lub ntsiab kom zoo dua yog los ntawm nws tus kheej - kho titanium dioxide passive zaj duab xis. Thaum immersed nyob rau hauv cov kua qaub acidic nplua nuj nyob rau hauv chloride ions, lub compact tiv thaiv txheej no muaj peev xwm regenerate tsis tu ncua nyob rau hauv cov kua cuam tshuam thiab nplawm abrasion. Tsis zoo li cov hlau tsis muaj hlau uas nws cov txheej txheem ua tau yooj yim ua tsis tau zoo hauv cov dej ntws, titanium tswj kev ruaj khov rau hauv cheeb tsam corrosion dhau mus ntev ua haujlwm tas mus li. Nws qhov siab tshaj plaws kev nyab xeeb ua haujlwm kub ncav cuag 770 degree, deb tshaj qhov ntsuas kub ntawm fluoropolymer- sheathed heaters, ua rau nws siv tau rau nruab nrab thiab siab - cov txheej txheem kub xws li evaporation, concentration thiab crystallization ntawm acidic brine. Tsis tas li ntawd, ntshiab titanium ua raws li cov qauv kev huv huv thiab tuaj yeem siv rau cov txheej txheem cua sov uas yuav tsum tau tswj xyuas kom huv si.
Txawm li cas los xij, cov kws tsim qauv tsim qauv yuav tsum txhais nws qhov kev siv tau kom meej. Ntev -lub sij hawm kev sib cuag nrog kub concentrated alkaline kua yuav degrade titanium cov ntaub ntawv tiv thaiv zaj duab xis thiab ua rau uniform nto corrosion. Media uas muaj hydrofluoric acid los yog soluble fluorides sai corrode titanium substrate thiab ua rau nruab nrab to. Kev xa cov titanium rhaub hauv qis-corrosion circulating dej kuj tsim cov khoom siv nyiaj txiag tsis tsim nyog, vim nws muaj peev xwm tiv thaiv -corrosion deb tshaj li cov txheej txheem siv tau.
Los ntawm kev tsim engineering tsim, forged titanium immersion heaters tseem yog qhov tseem ceeb tshaj plaws rau kev ruaj khov acidic brine ncig loops. Yog tias cov txheej txheem cov kua dej muaj alkalis, tshuaj fluoride lossis ua rau muaj kev hloov pauv ntawm pH ntau zaus, cov kws ua haujlwm yuav tsum xaiv monolithic PFA-clad heaters lossis fused quartz cua kub hloov. Kev tsom xam ntawm cov kua muaj pes tsawg leeg ua tau zoo ua rau cov cuab yeej laus zuj zus thiab pab cov tuam txhab sib npaug ntawm cov peev txheej pib thiab kev ua haujlwm ntev - lub sijhawm ua haujlwm ruaj khov.
