A kind of integral and intelligent clear water faucet specific complex NF membrane and preparation method thereof

A kind of integral and intelligent clear water faucet specific complex NF membrane and preparation method thereof, belongs to technical field of sewage.NF membrane is composite membrane, including non-woven fabrics supporting layer, ultra-thin middle support layer and ultra-thin dense separation layers, and non-woven fabrics supporting layer connects the side of ultra-thin middle support layer, and ultra-thin dense separation layers are connected to the opposite side of ultra-thin middle support layer.The filter element volume of the present invention is less, and function is more, and flux is bigger, and clean-up effect is more preferable.Still there is higher flux in relatively low pressure, the small organic molecule beneficial to body and low price inorganic salt can be retained with selective removal tap water harmful substance, water outlet is in good taste, after heating up water, container does not produce incrustation scale, can meet user to aquifer yield and the demand of producing water water quality.The main direction of studying of high-flux nanofiltration membrane is modified stratum disjunctum, and the flux and separating property that rare research starts with improving NF membrane from supporting layer and intermediate layer.
