PVDF Resin Rau Hollow Fiber Membrane Txheej Txheem (DS204 & DS204B)
PVDF hmoov DS204 / DS204B yog homopolymer ntawm vinylidene fluoride nrog solubility zoo thiab haum rau kev tsim cov PVDF daim nyias nyias los ntawm cov txheej txheem dissolving thiab ntaub.High corrosion kuj rau acids, alkali, muaj zog oxidizers thiab halogens.Zoo tshuaj stability kev ua tau zoo nrog aliphatic hydrocarbons, cawv thiab lwm yam organic solvents.PVDF muaj zoo heev anti-y-ray, ultraviolet hluav taws xob thiab aging kuj.Nws zaj duab xis yuav tsis nkig thiab tawg thaum muab tso rau sab nraum zoov ntev.Qhov tseem ceeb tshaj plaws ntawm PVDF yog nws qhov muaj zog hydrophobicity, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev sib cais xws li membrane distillation thiab membrane absorption.Nws kuj muaj cov khoom tshwj xeeb xws li piezoelectric, dielectric thiab thermoelectric zog. ntawm daim nyias nyias.
