Brine recycling tanks, seawater heating systems thiab electroplating pre{0}}kev kho da dej yog dominated los ntawm siab -chloride thiab tsis muaj zog acidic media, uas ua rau muaj kev hem thawj rau cov khoom cua sov zoo tib yam. Cov khoom siv hluav taws xob tsis zoo ib txwm muaj kev cuam tshuam sai sai thiab ua haujlwm luv luv, thaum cov raj quartz yog cov qauv tsis yooj yim thiab PFA cov cua sov raug txwv los ntawm qis- qhov kub thiab txias. Ntshiab titanium cua sov raj sawv tawm raws li cov kws tshaj lij los tiv thaiv- cov khoom siv cua sov ua kom haum rau siab - ntsev muaj ib puag ncig. Daim ntawv no txheeb xyuas lawv cov khoom siv tshwj xeeb, kev ua haujlwm zoo thiab qhov tsis zoo, thiab cov xwm txheej siv tau, nrog rau kev sib piv cov lus sib piv ntawm plaub lub ntsiab cua sov.
Titanium lub ntsiab kom zoo dua yog nyob rau hauv nws superior adaptability rau chloride - nplua nuj media. Its surface can spontaneously generate a dense, self-restoring oxide film in oxygen-containing aqueous environments. Txawm tias thaum muaj kev puas tsuaj los ntawm kev kub siab - cov kua dej nrawm los yog kev puas tsuaj me me, cov txheej txheem tiv thaiv kho nws tus kheej tam sim ntawd, tiv thaiv cov tshuaj chloride ions los ntawm kev cuam tshuam cov hlau matrix. Qhov tshwj xeeb ntawm tus kheej no-kev kho muaj peev xwm ua kom tshem tawm pitting thiab perforation tsis ua haujlwm feem ntau pom hauv cov khoom siv stainless hlau. In addition, titanium features low density, high specific strength and outstanding thermal fatigue resistance. Nws tseem nyob ruaj khov thiab tsis muaj qhov tsis zoo nyob rau hauv qhov rov ua cua sov dua - lub voj voog txias thiab ntev - lub sijhawm ua haujlwm tas mus li, ua kom cov cua sov zoo sib xws thiab cov khoom siv kev nyab xeeb.
Cov lus hauv qab no qhia txog cov khoom lag luam -cov kev ntsuas ntsuas tshiab rau cov cua sov hauv siab -chloride tsis muaj zog acid ib puag ncig:
表格
| Cua sov Tube hom | Chloride Anti-Pitting Muaj peev xwm | Thermal Fatigue Resistance | Tsis muaj zog Acid Stability | Lub neej ua haujlwm tsis tu ncua | Economic Practicality |
|---|---|---|---|---|---|
| Ntshiab Titanium | Sab saum toj -tier, tsis muaj kev pheej hmoo perforation | Zoo heev | Siab | 3-5 xyoos | Kev nqis peev siab, ultra- kev saib xyuas qis |
| 316 Stainless hlau | Nruab nrab, gradual pitting aging | Zoo | Nruab nrab | 6–12 lub hlis | Sib npaug rau qis - siv ntsev |
| Quartz Tube | Tsis zoo, ion permeable corrosion | General | Zoo heev | 1-2 xyoos | Siab fragility poob |
| PFA rhaub | Kev cais lub cev zoo | Nruab nrab | Zoo | 1.5-2 xyoos | Kub txwv |
Hauv qhov tseeb electroplating thiab seawater desalination industries, titanium cua sov raj xa cov tseem ceeb ntev -lub sij hawm muaj nqi. Lawv ua rau txo qis kev tsim khoom tsis txaus ntseeg tshwm sim los ntawm cov cua sov corrosion tsis ua haujlwm, txhim kho kev tsim khoom txuas ntxiv. Sib txawv los ntawm cov hlau raj uas tso tawm impurity ions, titanium tswj ultra- cov yam ntxwv tsis tshua muaj kuab lom, tiv thaiv cov tshuaj purity thiab stabilizing cov khoom tiav.
Txawm li cas los xij, cov ntaub ntawv titanium muaj qhov txwv tsis pub siv. Lawv yog cov rhiab heev rau kub concentrated alkali, uas tuaj yeem rhuav tshem cov yeeb yaj kiab oxide tiv thaiv thiab ua rau muaj kev sib txhuam ceev ceev. Lub caij no, cov khoom siv raw khoom kim heev thiab kev ua haujlwm nyuaj ua rau titanium tsis muaj txiaj ntsig rau cov dej tsis zoo tib yam -corrosion dej, ua rau kev ua haujlwm rov ua dua thiab cov nqi pov tseg.
Nyob rau hauv cov ntsiab lus, ntshiab titanium cua sov raj yog lub feem ntau txhim khu kev qha ntev -lub sij hawm cua sov xaiv rau siab - chloride thiab qaug zog acid cov txheej txheem. Cov tuam txhab lag luam yuav tsum nruj me ntsis xaiv titanium cua sov rau lub hom phiaj hnyav ntsev- muaj cov xwm txheej thaum siv tus nqi- cov ntaub ntawv siv tau zoo rau ib puag ncig me me kom tau txais txiaj ntsig zoo tshaj plaws ntawm kev ua haujlwm.
