Kev piav qhia
PVDF rau Kev Kho Dej Membrane yog siab -kev ua tau zoo fluoropolymer tshwj xeeb tsim los rau kev tsim cov membrane. Nws muab cov tshuaj tiv thaiv zoo heev, kev hloov kho hydrophilic compatibility, thiab ntev - lub sij hawm txhua yam kev ruaj ntseg, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov khoom siv txhim khu kev qha siv hauv cov dej thiab cov dej khib nyiab.
PVDF daim nyias nyias ua lub luag haujlwm tseem ceeb hauv kev kho dej niaj hnub, suav nrog microfiltration (MF), ultrafiltration (UF), thiab membrane bioreactor (MBR) systems. Kev ua tau zoo ntawm cov membranes nyob ntawm qhov zoo thiab sib xws ntawm PVDF resin siv hauv lawv cov fabrication.
Los ntawm cov ntaub ntawv engineering foundations, PVDF qib no yog optimized rau membrane casting thiab spinning txheej txheem. Nws qhia tau zoo heev solubility thiab daws stability nyob rau hauv raug membrane cov kuab tshuaj xws li NMP, DMAc, thiab DMF. Thaum lub sij hawm inversion theem, cov resin tso cai meej tswj qhov pore loj faib thiab daim nyias nyias morphology, uas ua rau cov membranes nrog siab permeability thiab txhim khu kev qha tuav.
Chemically, PVDF muaj kev tiv thaiv zoo rau cov tshuaj chlorine, oxidizing cov neeg ua haujlwm, acids, thiab alkalis feem ntau ntsib hauv dej thiab dej khib nyiab. Qhov kev tiv thaiv no ua rau cov membranes tuaj yeem tiv taus cov tshuaj tua kab mob ntau zaus, suav nrog kev cuam tshuam rau sodium hypochlorite thiab lwm yam tshuaj tua kab mob, tsis muaj kev puas tsuaj loj lossis tsis muaj zog txhua yam.
Nyob rau hauv cov nqe lus ntawm txhua yam kev ua tau zoo, PVDF daim nyias nyias muaj lub zog tensile siab thiab qaug zog, uas yog ib qho tseem ceeb rau kev tswj cov membrane kev ncaj ncees nyob rau hauv tas mus li kev nyuaj siab thiab backwashing tej yam kev mob. Cov khoom siv thermal stability kuj txhawb dej kub tu thiab ua haujlwm siab kub, nthuav tawm cov txheej txheem ua haujlwm yooj yim.
Lwm qhov txiaj ntsig tseem ceeb yog PVDF kev sib raug zoo nrog kev hloov kho hydrophilic. Los ntawm kev sib xyaw lossis kev kho saum npoo, daim nyias nyias wettability tuaj yeem txhim kho tau zoo, txo cov fouling thiab txhim kho cov dej ntws. Qhov no ncaj qha ua rau txo qis kev ua haujlwm siab, txo kev siv hluav taws xob, thiab lub neej ua haujlwm ntev dua membrane.
