Kev siv titanium pas nrig hauv kev lag luam chlor-alkali

Kev lag luam chlor-alkali yog kuv lub teb chaws cov khoom siv raw khoom. Nws cov khoom yog cov khoom siv tshuaj lom neeg yooj yim thiab siv dav hauv textile, papermaking, tshuaj tua kab, tshuaj, khoom siv hauv tsev, metallurgy thiab lwm yam lag luam. Chlor-alkali yog ib qho ntawm cov haujlwm tseem ceeb hauv kev lag luam tshuaj thiab tseem yog tus neeg siv khoom tseem ceeb ntawm titanium cov ntaub ntawv hauv kuv lub teb chaws. Kev lag luam chlor-alkali yog kev lag luam corrosive heev. Cov txheej txheem kev tshaj tawm thiab cov khoom lag luam hauv nws cov txheej txheem tsim khoom, xws li saturated brine, chlorine ntub dej, caustic soda, hydrochloric acid, sulfuric acid, thiab lwm yam, yog corrosive heev. Yog li ntawd, ua tib zoo xaiv yuav tsum tau ua nyob rau hauv chlor-alkali ntau lawm tej yaam num. Cov txheej txheem ntawm cov khoom siv, txwv tsis pub muaj tshwm sim xws li khiav, tawg, poob, thiab to yuav tshwm sim thaum lub sij hawm tsim khoom, uas yuav cuam tshuam rau ib txwm tsim thiab cov khoom zoo. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kuv lub teb chaws kev lag luam chlor-alkali thiab qhov nruam tshwm sim ntawm cov cuab yeej tshiab thiab cov txheej txheem tshiab, daim ntawv thov titanium hauv kev lag luam chlor-alkali tau maj mam nthuav dav. Nws yog dav siv nyob rau hauv kev tsim cov hlau anode electrolyzers, ion membrane electrolyzers, ntub oxygen coolers, refined brine preheaters, dechlorination yees, chlorine txias thiab ntxhua khaub ncaws, thiab lwm yam. Cov khoom ntawm cov khoom siv no yog ua los ntawm cov khoom tsis yog xim hlau. Vim tias cov khoom siv tsis zoo, thermal stability thiab kev ua haujlwm ntawm cov khoom tsis yog xim hlau, cov khoom siv yog loj, siv zog, siv sijhawm luv thiab tsis zoo.

Titanium rods muaj kev tiv thaiv corrosion zoo heev thiab cov khoom siv kho tshuab thiab tau siv dav hauv ntau qhov haujlwm. Tshwj xeeb tshaj yog nyob rau hauv kev siv tshuaj lom neeg, titanium tuaj yeem hloov cov hlau tsis muaj hlau ua cov khoom siv corrosion-resistant, uas yog qhov tseem ceeb rau kev ua haujlwm ntev ntawm cov khoom siv, txo cov nqi, tiv thaiv kev ua qias tuaj, thiab txhim kho kev tsim khoom. Nyob rau hauv xyoo tas los no, cov titanium siv nyob rau hauv kuv lub teb chaws cov tshuaj lom neeg kev lag luam tau txuas ntxiv nthuav dav, thiab ntau npaum li cas tau nce xyoo los ntawm lub xyoo. Titanium tau dhau los ua ib qho ntawm cov khoom tseem ceeb los tiv thaiv corrosion rau cov khoom siv tshuaj. Raws li cov khoom siv tiv thaiv corrosion-resistant siv hauv cov khoom siv tshuaj, titanium tau dhau los ua cov khoom siv zoo tshaj plaws hauv cov khoom siv tshuaj.

Kev lag luam chlor-alkali yog ib qho tseem ceeb ntawm cov khoom siv raw hauv kev lag luam, thiab nws cov khoom tsim thiab kev loj hlob muaj kev cuam tshuam zoo rau kev lag luam hauv lub tebchaws. Qhov no yog vim tias titanium qhov kev tiv thaiv corrosion rau chloride ions zoo dua li siv cov hlau tsis muaj steel thiab lwm yam hlau tsis muaj hlau. Tam sim no, titanium yog siv dav hauv kev lag luam chlor-alkali los tsim cov hlau anode titanium electrolyzers, ion membrane electrolyzers, ntub chlorine coolers, refined brine preheaters, dechlorination yees, chlorine txias thiab ntxhua khaub ncaws, thiab lwm yam. ua los ntawm cov khoom tsis yog xim hlau (xws li graphite, polyvinyl chloride, thiab lwm yam). Vim tias cov khoom siv tsis zoo, thermal stability thiab kev ua haujlwm ntawm cov khoom tsis yog xim hlau, cov khoom siv yog loj, siv zog thiab muaj lub neej luv luv. , cuam tshuam cov khoom zoo thiab ua paug rau ib puag ncig. Yog li ntawd, txij li xyoo 1970, kuv lub teb chaws tau hloov pauv cov roj teeb graphite txuas ntxiv nrog cov roj teeb hlau anode thiab ion membrane roj teeb, thiab hloov graphite coolers nrog titanium ntub chlorine coolers, tag nrho cov no tau ua tiav cov txiaj ntsig zoo.

Piv txwv li: Daim ntawv thov ntawm titanium ntub chlorine txias. Lub electrolysis ntawm lub rooj ntsev los tsim cov dej qab zib caustic yuav tsim ib tug loj npaum li cas ntawm kub kub thiab ntub chlorine roj. Qhov kub yog feem ntau ntawm 75 thiab 95 degree, thiab nws yuav tsum tau txias thiab qhuav ua ntej siv. Yav dhau los, kuv lub teb chaws tsim cov roj chlorine los ntawm electrolysis ntawm ntsev muaj teeb meem nrog cov txheej txheem txias tsis tsim nyog lossis corrosion ntawm cov khoom siv cua txias, uas cuam tshuam rau cov zis thiab cov roj chlorine zoo, thiab tseem ua rau muaj kuab paug rau ib puag ncig. Kev tsim cov titanium coolers resistant rau kub ntub chlorine corrosion tau hloov lub ntsej muag ntawm chlorine ntau lawm nyob rau hauv kev lag luam chlor-alkali. Titanium tsis tshua muaj corrosion-resistant nyob rau hauv high-temperature, ntub chlorine ib puag ncig. Hauv dej chlorine ntawm chav tsev kub, qhov corrosion ntawm titanium yog 0.000565mm/a; Hauv dej chlorine ntawm 80 degree, qhov corrosion ntawm titanium yog 0.00431mm / a; Hauv cov dej chlorine uas muaj 95%, hauv cov roj chlorine ntub dej, qhov corrosion ntawm titanium ntawm chav sov yog 0.00096mm / a. Siv tau ze li ntawm 20 xyoo thiab tseem nyob zoo.
