Daim ntawv uas muaj ntshiab si Titanium nyob rau hauv kev lag luam tshuaj
Oct 14, 2016

Titanium alloy muaj corrosion yav tom ntej kuj thiab txhua yam khoom, uas nyob nrog siv nyob hauv cov tuam tsev. Particular, tshuaj kev lag luam, nrog titanium daim ntawv thov yuav hloov lub stainless hlau ua corrosion resistant khoom uas yuav mus cuag kev pab txoj hauj lwm ntawm cov khoom, txo nqi, tiv thaiv kev muaj kuab paug thiab txhim kho productivity thiab hais txog muaj ib qho tseem ceeb heev RESPONSIBILITIES.


Xyoo tsis ntev los no, qhov uas tus tau txais cov titanium siv nyob rau hauv kev lag luam hauv lub teb chaws Suav tshuaj tau expanding lawm, thiab cov titanium muaj lawm ntau zog xyoo los ntawm lub xyoo. Titanium kuj yog ib qhov tseem ceeb los tiv thaiv corrosion siv cov ntaub ntawv siv tshuaj. Titanium, raws li ib yam corrosion resistant li yam khoom siv hauv tshuaj cog, kuj yog ib qho khoom hauv tshuaj engineering khoom zoo tagnrho.


Kev lag luam alkali Chlor


Kev lag luam alkali Chlor yog ib qho kev ua lag luam tseem ceeb sau raw clear, cov ntau lawm thiab kev loj hlob ntawm ib feem ntawm tus economy lub teb chaws zoo kawg thiab. Qhov no yog vim hais tias cov corrosion kuj muaj titanium los chloride ion zoo dua cov hlau stainless thiab lwm yam uas tsis yog-ferrous co. Ntawm nimno hauv lub chlor alkali kev lag luam yog nyob rau manufacture titanium anode hlau electrolyzer thiab ion-txauv membrane electrolyzer, ntub dej tshuaj cia txias ces, refined brine preheater, tus dechlorination ntawm cov tshuaj chlorine cua txias ntauwd, ntxuav ntauwd thiab lwm yam.. Lub Cheebtsam lub ntsiab ntawm cov no yav dhau los siv cov ntaub ntawv uas tsis yog-nws yog xim hlau (xws li graphite, PVC etc.), vim hais tias cov kev kawm ntawm txhua yam khoom, lub stability thermal uas muaj ntaub ntawv nws yog xim hlau thiab ua tsis zoo tagnrho, uas ua rau hnyav, khoom noj muaj zog, luv pab lub neej, thiab nws ua rau qhov zoo tshaj ntawm cov khoom thiab tej kuab paug rau. Vim li no, peb lub teb chaws txij thaum 70s, pib siv cov hlau anode electrode thiab ion membrane fais tank, txhob siv graphite electrode, muaj titanium ntub dej tshuaj cia siv graphite cia txias, txias tau tiav tau zoo.


Piv txwv li: daim ntawv thov titanium ntub dej tshuaj cia txias. Zus tau tej cov dej qab caustic yog tsim kom muaj coob tus kub ntub dej tshuaj, cov kub thiab feem ntau yog 75 ~ 95 degrees Celsius, yuav tsum tau txias thiab qhuav los siv. Nyob rau hauv peb lub teb chaws, zus tau tej cov tshuaj raws li electrolysis yuav tsis tsim nyog los yog cov corrosion uas muaj cua txias khoom raug rau cov zis thiab pa tshuaj chlorine zoo, thiab qhov chaw yog tiag nro. Kub ntub dej tshuaj corrosion ntawm titanium cia txias rau hauv ntau lawm, hloov cov siv thiab ua rau kev lag luam alkali chlor nyob rau hauv cov outlook ntau lawm. Titanium nyob rau hauv cheeb tsam tshuaj ntub dej kub yog heev tiv taus corrosion, tshuaj titanium sov qhov twg corrosion txog 0.000565 hli/ib ntawm 80 DEG C; dej tshuaj, corrosion tus nqi uas titanium yog hli 0.00431/ib; ntub dej tshuaj, corrosion tus nqi uas titanium sov rau cov uas muaj 95% 0.00096 hli/ib. Muaj ntau tus siv feem ntau chlor alkali titanium ntub dej tshuaj chlorine cia txias, ib txhia uas muaj lawm siv tau yuav luag 20 xyoo, yog tseem lawm.


kev lag luam dej qab


Dej qab ntoo tshauv yog ib qhov yooj yim tshaj plaws tshuaj raw cov ntaub ntawv, nws yog ncaj qha hais txog txoj kev loj hlob ntawm tus economy lub teb chaws. In the Process of yuav ua tau sodium carbonate, roj nruab nrab yog NH3 thiab CO2, ua kua nruab nrab rau cov tshuaj NaCl, NH4Cl, NH4HCO3 thiab Cl - mob siab concentration, siv cov hlau thiab laj cam khwb cia khoom rau carbonation carbonation ntauwd tubular txias, cia txias, thaum tshav kub kub, kua siv lead ua txheej cia txias ntsiab khoom, tsis muaj corrosion, corrosion loj to, pab txoj hauj lwm uas tsis pub tshaj 3 xyoos. Xyoo 1975-xyoo 1977, Tianjin sis dej qab zib cog thiab Dalian kev lag luam tshuaj siv tuam txhab ntawm titanium ua qauv qhia ntawv ua hauj lwm, cov nyhuv tsab ntawv teev npe ntawm carbonation ntauwd cua txias raj 63 x 2 hli phaj titanium, titanium kom sov exchanger lwm cia txias, titanium twj tso kua mis, CO2 turbo compressor rotor, Ti-6Al-4V alloy impeller no zoo heev, qhov no yog txoj kev lag luam nrog titanium tshuab cov transformation thiab tshiab peb nrog tus tso zis txhua xyoo 600 txhiab tons ntawm cov dej qab ntoo tshauv cog plays ib tug qauv.


Piv txwv li, yog tsis ib cam khwb cia hlau yeeb sab saum toj sis dej qab zib cog distillation pej thuam cov ammonia kev condenser titanium ntshiab raj. Ammonia condenser in the process of yuav ua tau yog sodium carbonate, ammonia pej thuam distillation distilled hws khoom, uas yog muaj li ntawm ob cam khwb cia hlau txias kem, txhua lub thawv taub 2.5 m, siab 1.2 m, yog tseem cia nrog Officer 63 * 6 * 2986 hli cam khwb cia hlau tubular 214, 428 cag ob thawv. Siv thermosetting phenolic kua roj vanish preservation, yog ob sab hauv thiab lwm lub raj tawm xov xwm sab nrauv rau H2O NH3, CO2, vapor, kub txog 95 degrees celsius. Raj NH4Cl niam dej cawv, kub exchanger thiab nruab nrab yeeb nkab. Ntawm tus mob no, tus corrosion ntawm cov yeeb nkab cam khwb cia hlau loj, yog ib xyoos uas yog ib feem ntawm cov yeeb nkab corrosion perforation, 2 xyoos corrosion puas siv loj, tsis txhob siv. Yuav kom daws tau cov ammonia condenser nyob hauv lub corrosion loj ntawm cov yeeb nkab cam khwb cia hlau, laj cam khwb cia cov yeeb nkab yuav hloov tag nrho TA2 titanium raj, specifications Officer 60 * 2 * 3010 hli, titanium yeeb tag thiab laj cam khwb cia paj phaj siv O yam roj hmab sealing nplhaib. Qhov no nws yog Chinaand #39; s thawj muaj dej qab cua txias tubular distillation ntauwd txim ntawm cov raj titanium ntshiab. Muab tso rau hauv zov me nyuam ntau tshaj ob xyoos, tus tau siv raj rau tus tuaj kuaj tsev macro, tsis muaj corrosion phenomenon yuav tsum siv lub neej mus txog 20 xyoo, 10 lub sij hawm ntev dua cov yeeb nkab hlau cam khwb cia. Vim tias cov titanium raj ua hauj corrosion, kub zoo hloov efficiency (cam khwb cia hlau yeeb thaum muaj 3 xyoos kho dua ntawm lub tshav kub hloov efficiency uas tsis ua hauj lwm thaum ntxov, nruab nrab, lig), NH4Cl raj preheating rov qab tshav kub lug txhim khu cov dej cawv, dej cawv rau qhov kub thiab txias distillation, txuag tau ntau chav, economic nyiaj cuab kev.
