Kev lag luam kws tshuaj yog ib qho tseem ceeb uas cuam tshuam rau tib neeg lub cev thiab lub hlwb kev noj qab haus huv. Nws suav nrog ntau qhov chaw, suav nrog tshuaj, khoom siv kho mob, thiab khoom siv kho mob, thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam hauv tebchaws. Vimtitaniumtsis yog - lom, tsis muaj mob, thiab biocompatible heev, nws yog dav siv hauv kev lag luam kws tshuaj.
Hauv kev tsim tshuaj, kev tsim cov tshuaj inevitably cuam tshuam nrog acids, alkalis, thiab ntsev, ua rau cov khoom siv tshuaj muaj kev cuam tshuam rau corrosion thiab puas. Kev siv cov cuab yeej steel tsis tsuas yog ua tsis tau zoo los daws qhov teeb meem ntawm corrosion hnyav, tab sis kuj ua rau muaj kev puas tsuaj loj ntawm cov neeg ua haujlwm, cov khoom siv, thiab cov peev txheej nyiaj txiag, yog li cuam tshuam kev tsim khoom ib txwm muaj. Kev siv cov khoom siv titanium, txawm li cas los xij, daws qhov teeb meem no zoo.
Hauv kev tsim khoom ntawm ntau qhov chaw siv tshuaj loj, cov cuab yeej ua los ntawm titanium nthuav tawm zoo heev corrosion kuj thiab tau txais txiaj ntsig kev lag luam tseem ceeb.
1. Vitamin B1 Production
Nyob rau hauv Suav teb, vitamin B1 feem ntau yog tsim los ntawm hydrochloric acid hloov dua siab tshiab txoj kev, nrog rau cov khoom tiav nyob rau hauv lub cyclone drying thiab ob -theem cyclone sib cais. Cov txheej txheem nruab nrab yog thiamine hydrochloride, nrog pH ntawm 2.5 thiab qhov kub ntawm 110 degree, ua rau nws muaj zog heev. Cov khoom siv ziab thawj yog ua los ntawm cov hlau tsis muaj steel; nyob rau hauv tsuas yog ib xyoos ntawm kev siv, corrosion tshwm sim perforations nyob rau hauv lub puab phab ntsa, uas ua rau muaj mob loj paug ntawm cov tshuaj cov khoom.
Tom qab kev txhim kho titanium-kab kauv feeders, cyclone separators, vortex chambers, hoppers, tso cov kav dej, thiab cov pa roj chambers, qhov ntau lawm yield tus nqi rau vitamin B1 nce los ntawm ntau tshaj 95% mus rau 100%. Tsis tas li ntawd, cov cuab yeej siv tau pom tias tsis muaj cov tsos mob ntawm corrosion tom qab ntau tshaj xya xyoo ntawm kev siv, thiab tus nqi ntawm cov titanium hauv ob sab phlu tau recouped nyob rau hauv peb lub hlis.
2. Vitamin C ntau lawm
Vitamin C yog tsim los siv sorbitol ua raw khoom. Nws yog thawj zaug fermented los ntawm Acetobacter los tsim sorbitose, tom qab ntawd fermented los ntawm Pseudomonas los tsim qis -concentration gluconic acid, uas yog concentrated thiab hloov mus rau hauv cov khoom kawg ntawm hydrochloric acid.
Titanium yog corrosion kuj heev -resistant nyob rau hauv siab -kub gluconic acid. Hauv cov txheej txheem tsim khoom no, titanium plhaub- thiab- raj kub exchangers, titanium DHC-500 disc-type sedimentation centrifuge nrog tsis siv neeg slag tawm, thiab TC4 cam khwb cia impellers tau siv ntau xyoo yam tsis muaj kev cuam tshuam.
3. Tshuaj tua kab mob ntau lawm
Lub ntsiab raw khoom rau cov tshuaj synthesis ntawm chloramphenicol (ib qho tshuaj tua kab mob) yog methyl dichloroacetate, uas muaj kwv yees li 2% trichloroethylene. Yog tias cov khoom siv hlau tau siv rau hauv cov txheej txheem kho kom zoo, kev xeb hnyav yuav tshwm sim; Txawm li cas los xij, txij li hloov mus rau cov khoom siv titanium, cov cuab yeej siv tau zoo li niaj hnub no.
4. Kev tsim tshuaj loog
Procaine hydrochloride, siv los ua tshuaj loog hauv zos, yog tsim los ntawm p-nitrotoluene. Thoob plaws hauv tag nrho cov txheej txheem tsim khoom-los ntawm oxidation los tsim p-nitrobenzoic acid, los ntawm acetic acid ntxuav, niam cawv rov qab-txhua yam cuam tshuam rau cov mob hnyav heev. Yog li ntawd, cov khoom siv ntau lawm suav nrog cov cylinders sab hauv ua los ntawm titanium-steel composite plates, titanium bubblers, glacial acetic acid recirculation condensers, thiab gas-kua separators, yog li daws cov teeb meem corrosion.
5. Kev tsim cov tshuaj tiv thaiv kab mob thiab lwm yam tshuaj
Alendazole (Tetramizole) yog cov tshuaj tua kab mob zoo heev rau cov kab mob hauv plab hnyuv. Cov khoom siv stainless hlau yog thawj zaug siv hauv kev tsim cov khoom no, tab sis corrosion coj mus rau cov khoom paug. Qhov teeb meem corrosion tau ua tiav tiav los ntawm kev hloov cov kav dej thiab cov twj tso kua mis nrog cov titanium.
Nitrochlorophenol yog ib qho tshuaj kho tsiaj uas muaj txiaj ntsig zoo rau kev kho cov kab mob siab rau hauv cov nyuj thiab yaj, tsim siv sulfuric acid, nitric acid, glacial acetic acid, thiab chlorine - muaj cov tshuaj. Lub titanium agitator tau nruab rau hauv lub tank dissolution thiab tau ua haujlwm ib txwm mus rau hnub no. Tsis tas li ntawd, activated carbon decolorization yog siv dav hauv kev tsim tshuaj; Tom qab hloov lub stainless hlau nqus lim nrog titanium ib qho, nws tseem nyob hauv kev ua haujlwm zoo tshaj plaws rau cuaj xyoo.
Hauv kev tsim cov brominated amino acids txawv teb chaws, titanium reactors yog siv nyob rau hauv bromination, sib cais, ntsev los nag, extraction, thiab distillation txheej txheem. Hauv Suav teb, kev siv cov khoom siv titanium kuj tseem tsim nyog rau kev tsim cov tshuaj tiv thaiv kab mob los ntawm quinoline derivatives, tshuaj schistosomiasis uas cuam tshuam nrog cov tshuaj chloride ions, tshuaj tiv thaiv kab mob, thiab tshuaj rheumatism. Lwm daim ntawv thov, xws li penicillin esterification hlab ntsha, saccharification tso tsheb hlau luam, chloramphenicol nyias - zaj duab xis evaporators, ananin reactors, methoxyphenazone lim, dimethyl sulfate coolers, thiab tshuaj kua tshuaj lim, txhua yam qhia tau hais tias ob qho tib si ua tau thiab tsim nyog ntawm kev siv lawv cov ntaub ntawv .
