Hauv kev hloov pauv ntawm rov qab osmosis (RO) cov tshuab, cov khoom siv membrane-tseem hu ua cov hlab ntsha siab- ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom membrane, tiv thaiv kev kub ntxhov, thiab ua kom lub cev sib khi. Kev xaiv cov khoom siv vaj tse ncaj qha cuam tshuam rau kev nyab xeeb, kav ntev, thiab cov nqi tu. Nrog rau kev nce qib hauv cov khoom siv science thiab kev tsim khoom, cov khoom siv hauv tsev membrane tau hloov zuj zus los ntawm cov hlau mus rau cov khoom sib xyaw thiab cov polymers siab heev.
Thaum Ntxov: Lub Sij Hawm Ntawm Hlau Vaj Tsev
Nyob rau theem pib ntawm RO thev naus laus zis, cov tsev nyob hauv daim nyias nyias tau ua los ntawm cov hlau tsis muaj steel lossis txhuas alloys. Cov ntaub ntawv no muaj lub zog siab, siab tsis kam, thiab yooj yim ntawm fabrication, haum rau thaum ntxov desalination thiab muaj dej ntshiab tshuab.
Txawm li cas los xij, cov vaj tsev hlau muaj ob qhov teeb meem loj: kev cuam tshuam rau corrosion, tshwj xeeb tshaj yog nyob rau hauv saline los yog acidic ib puag ncig, thiab hnyav hnyav, uas nce nqi installation thiab txij nkawm.
Kev Hloov Pauv: Qhov Rise ntawm FRP Membrane Housings
Txij li thaum xyoo 1980s, kev loj hlob ntawm FRP (Fiber Reinforced Plastic) thev naus laus zis tau coj FRP vaj tse los hloov cov vaj tsev hlau, ua qhov kev xaiv tseem ceeb rau kev lag luam RO.
FRP vaj tse muaj lub zog siab, tiv thaiv corrosion, lub teeb yuag, thiab lub neej ntev. Lawv tuaj yeem tiv taus qhov siab ntawm 300 txog 1200 psi thiab tau siv dav hauv seawater desalination, boiler feedwater, thiab kev lag luam ua zaub mov.
Ntxiv mus, FRP vaj tse tuaj yeem hloov kho nrog cov txheej txheem sib txawv (xws li, epoxy lossis polyester resins) kom haum rau ntau yam dej zoo thiab kev xav tau siab.
Niaj hnub nimno theem: Innovation nyob rau hauv Polymer Engineering Materials
Nyob rau hauv xyoo tas los no, siab -kev ua tau zoo polymers xws li PVC, PVDF, PP, thiab PA tau nkag mus rau hauv lub membrane vaj tsev lag luam, tshwj xeeb tshaj yog nyob rau hauv me me thiab nruab nrab -cov dej ntshiab huv, chav kuaj teeb, thiab RO chav nyob.
Cov ntaub ntawv no muaj kev ruaj ntseg zoo heev, kev tiv thaiv corrosion, txo cov nqi tsim khoom, thiab rov ua dua tshiab, ua raws cov hom phiaj kev ruaj ntseg.
Txawm li cas los xij, nyob rau hauv siab -siab kev lag luam kev siv xws li seawater desalination, polymer vaj tse tseem tsis tau tag nrho hloov FRP vim muaj kev txwv siab -FRP tseem yog cov khoom nyiam.
Los ntawm cov hlau mus rau FRP thiab cov polymers siab heev, cov evolution ntawm cov ntaub ntawv membrane vaj tsev tsom iav qhov kev nce qib ntawm cov tshuab membrane thiab kev txhim kho kom ruaj khov. Nrog rau yav tom ntej kev tsim kho tshiab hauv cov ntaub ntawv tshawb fawb, kev lag luam RO membrane tshuab yuav ua tiav kev ua haujlwm siab dua, kev ua neej ntev dua, thiab kev siv hluav taws xob qis dua, muab lub hauv paus ruaj khov rau kev ruaj ntseg dej thoob ntiaj teb thiab rov siv dua.
