1. Kev tsim cov khoom siv petrochemical thiab chemical ntim khoom
Kev tsim cov khoom siv petrochemical ntim khoom yog cov ntawv thov ib txwm sivtitanium-steel composite phajcov ntaub ntawv, thiab nws daim ntawv thov ntim tau ib txwm nyob hauv thawj qhov chaw. Hauv kev lag luam tshuaj, titanium muaj kev ruaj ntseg zoo nyob rau hauv ntau yam kua qaub, alkali, thiab ntsev xov xwm, tshwj tsis yog rau plaub inorganic acids thiab corrosive txhuas chloride. Yog li ntawd, titanium yog ib qho zoo heev los tiv thaiv - cov khoom siv corrosion hauv kev lag luam tshuaj thiab tau siv ntau thiab ntau dua. Piv txwv li, lub tshuab nqus tsev yees, distillation yees, thiab cov khoom siv hluav taws xob hloov pauv hauv cov roj av refining nroj tsuag; ntau cov tshuaj tiv thaiv pej thuam, nag lossis daus tank, thiab nplawm crystals hauv cov nroj tsuag tshuaj. Urea yog cov tshuaj chiv tseem ceeb. Thaum lub sij hawm tsim khoom, urea, ammonia, ammonium carbamate, thiab lawv cov khoom sib tov yog corrosive heev nyob rau hauv qhov kub thiab txias thiab siab - siab. Tom qab sivtitanium- steel clad daim hlaulos hloov cov hlau tsis muaj steel, lub neej kev pab cuam ntawm cov cuab yeej siv tau ntev heev, thiab lub sijhawm txij nkawm tau nce zoo heev. Yog li, cov cuab yeej tseem ceeb hauv kev tsim cov urea tam sim no siv titanium -steel composite daim hlau. Titanium muaj qhov tshwj xeeb corrosion tsis kam rau chlorine dioxide, chlorous acid, chlorite, thiab lwm yam tshuaj bleaching. Yog li ntawd, titanium-steel composite daim hlau yog siv nyob rau hauv textile printing thiab dyeing. Nws kuj tseem muaj cov ntawv thov tseem ceeb hauv cov khoom siv tshuaj dawb hauv kev lag luam thiab kev lag luam ntawv.
2. Kev tsim khoom ntawm lub tshuab nqus tsev ntsev ua khoom siv
Titanium thiab nws cov alloys muaj kev tiv thaiv zoo rau cov dej hiav txwv thiab cov tshuaj chloride corrosion thiab dej yaig. Txij li xyoo 1980s, titanium-steel composite phaj ntsev- cov khoom siv tau muab tso rau hauv lub tshuab nqus tsev ntsev- ua cov nroj tsuag xws li Sichuan thiab Inner Mongolia. Vim tias titanium nto yog du thiab corrosion- tiv taus, nws muaj txiaj ntsig zoo ntawm kev tiv thaiv ntsev scaling ntawm phab ntsa ntawm lub tank evaporation thiab ua kom lub sijhawm ntxuav lub tank ntev. Lub evaporation chamber ua los ntawm titanium-steel composite phaj muaj qhov zoo ntawm kev ua kom qeeb corrosion thiab ntsev scaling, prolonging lub voj voog ntau lawm, thiab txhim kho lub uniformity ntawm ntsev. Kev siv cov khoom siv titanium hauv lub tank evaporation ntawm cov cuab yeej tseem ceeb ntawm qhov project tau thawb daim ntawv thov ntawm titanium ib kauj ruam loj rau pem hauv ntej. Tsuas yog ob txheej ntsev no xwb- cov khoom siv thiab cov evaporation tank siv titanium thiab titanium- cov hlau sib xyaw phaj, ncav cuag 360 tons. Thiab ib qho ntawm cov neeg tsim khoom loj ntawm titanium steel composite panels. Daim ntawv thov ntawm titanium- steel clad phaj txo cov nqi siv cov khoom siv ntsev, qhov kev tiv thaiv corrosion zoo dua li ntawm duplex stainless hlau, kev pab lub neej ntev, thiab tus nqi qis dua li kev lag luam tus nqi siv. duplex stainless hlau.
3. Desalination teb
The world's freshwater resources are insufficient. China is also one of the 13 water-poor countries in the world. The per capita freshwater resources are only 1/4 of the world's per capita resources, and the distribution of water resources is uneven. A large amount of fresh water is concentrated in the south, and the freshwater resources in the north are only It can be said that the whole freshwater resource situation is not optimistic. Titanium and its alloys have excellent resistance to seawater and chloride solution corrosion and fluid erosion. And titanium is non-toxic, making it an ideal material for desalination equipment. In the next 20 years, the international desalination market will have nearly 70 billion US dollars of business opportunities. China will have a multi-billion dollar market in the future. At present, desalination enterprises from the United Kingdom, France, Singapore, Denmark, Japan, and other countries have come to China to engage in technology, investment, and construction activities. At present, the Chinese market has become an important strategic market for foreign seawater desalination products and equipment manufacturing groups. The application climax of the titanium -steel composite ntawv.
4. Cov txheej txheem hauv cheeb tsam ntawm PTA cov khoom siv
Purified terephthalic acid (PTA) oxidation reactor yog qhov nyuaj rau kev tsim khoom, nrog cov kev xav tau siab, qhov hnyav ua haujlwm ntawm cov cuab yeej siv, thiab cov kev xav tau siab rau kev tsim khoom. Nws cov cuab yeej tsim khoom thiab cov khoom siv ib txwm tau monopolized los ntawm txawv teb chaws. Thaum Lub Kaum Hli 2010, National Development thiab Reform Commission tau pom zoo rau qhov project ua qauv qhia hauv cheeb tsam thiab qhov haujlwm tseem ceeb ntawm kev lag luam petrochemical - loj - nplai purified terephthalic acid (PTA) oxidation reactor ntawm ib lab tons hauv Nanjing Bao. Lub Hoobkas cheeb tsam ntawm Selangor Co., Ltd. mus offline. Kev vam meej ntawm cov cuab yeej no tau rhuav tshem cov kev cuam tshuam ntawm cov teb chaws txawv teb chaws rau cov cuab yeej tseem ceeb ntawm loj - nplai PTA kev teeb tsa hauv kuv lub teb chaws. Cov khoom siv feem ntau yog titanium- steel clad daim hlau.
5. Kev tsim cov khoom siv hluav taws xob nuclear
Thick clad thiab loj -dav titanium- steel clad daim hlau yog cov ntaub ntawv tseem ceeb rau condenser raj ntawv hauv cov khoom siv hluav taws xob nuclear. Nws yog kwv yees tias nyob rau hauv kaum xyoo tom ntej no, Tuam Tshoj yuav ntxiv qhov nruab nrab txhua xyoo nuclear fais fab kev teeb tsa muaj peev xwm ntawm 7.7 lab kilowatts, sib xws rau qhov nce ntawm qhov kev thov rau titanium- steel clad daim hlau rau nuclear zog. Lub ntim yog kwv yees li 924 tons hauv ib xyoos lossis ntau dua, thiab qhov chaw ua lag luam loj heev. Nyob rau hauv lub neej yav tom ntej, titanium- steel clad phaj rau 1 lab kilowatts ntawm nuclear fais fab nroj tsuag yuav qhia explosive kev loj hlob, thiab daim ntawv thov kev cia siab kuj yog ib tug kuj optimistic.
6. Dej hiav txwv Engineering
Nyob rau hauv xyoo tas los no, titanium-steel composite panels tau ntxiv kev siv tshiab, uas yog, los tiv thaiv- cov ntaub ntawv corrosion rau steel qauv tau pib siv rau hauv kev lag luam marine civil engineering. Qhov no tsis yog vim nws cov nqi qis xwb tab sis kuj los ntawm qhov pom ntawm vuam thiab kev teeb tsa ntawm lub ntsiab steel qauv, nws yog ib qho tsim nyog yuav tau siv titanium- steel clad phaj. Qhov zoo ntawm no titanium-steel composite sheet yog:
(1) Titanium yeej tsis corroded hauv dej hiav txwv, thiab titanium hlau ions yuav tsis yaj;
(2) Cov kab mob titanium tsis yog - tshuaj lom thiab tsis muaj kev cuam tshuam rau ib puag ncig ecological ib puag ncig, thiab yog cov khoom siv rau ib puag ncig.
Lub titanium- steel clad phaj uas tsim los ntawm kev kub ceev txuas ntxiv yog ib lub phaj nyias, uas yog siv rau hauv cov txheej txheem marine steel, thiab daim ntawv thov teb yog marine civil engineering.
titanium{0}} steel clad phaj tsis tsuas yog muaj qhov zoo heev corrosion kuj ntawm titanium cladding tab sis kuj muaj lub zog thiab plasticity ntawm cov pa roj carbon yooj yim. Nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov khoom siv hauv corrosion- tiv taus ib puag ncig. Nrog rau kev txhim kho tas mus li ntawm cov txheej txheem tsim khoom ntawm clad daim hlau, hom thiab specifications ntawm titanium steel clad daim hlau yuav nce ntxiv, thiab lawv daim ntawv thov teb yuav ntau dua thiab ntau dua.
