Processing technology of low-resistance warp-knitted drinking water filter material

Abstract

The invention provides a processing technology of a low-resistance warp-knitted drinking water filter material, and solves the technical problems that an existing filter membrane is too complicated instructure, cannot allow water to pass through quickly, is low in separation speed and the like. The processing technology of the low-resistance warp-knitted drinking water filter material comprises the following steps: a, pouring dimethyl sulfoxide, polysulfone, polyethylene sulfone, zinc chloride, methanol, an antibacterial agent and a pore-foaming agent into a general stirring machine, and performing filtering and defoaming to prepare membrane casting liquid; b, pouring the membrane casting liquid into a general membrane casting machine, coating the surface of a warp knitting fabric with the membrane casting liquid to prepare a polysulfone ultrafiltration base membrane, and compounding the warp knitting fabric and the polysulfone ultrafiltration base membrane to form a supporting bottommembrane; c, cleaning the supporting bottom membrane in clean water at 40 DEG C; d, drying the cleaned supporting bottom membrane in a drying oven; e, conveying the dried supporting bottom membrane into a general membrane coating machine to obtain a finished membrane product; and f, winding the finished membrane product. The processing technology has the advantage of separation quickness.

Description

technical field [0001] The invention relates to a processing technology of a low-resistance warp knitted drinking water filter material. Background technique [0002] Existing water sources are generally polluted by organic matter, and compound pollution such as high organic matter and high turbidity appears in some areas. The traditional coagulation-sedimentation-filtration-disinfection process has low filtration accuracy, high usage of disinfectants and coagulants, and has a great impact on water quality. The treated water can no longer meet the requirements of the new drinking water standard. Membrane separation technology is an important new technology for deep purification of drinking water and ensuring water quality safety. Membrane separation technology is a technology that uses pressure as the driving force and uses membranes of different pore sizes to screen and separate water and particulate matter in water (particles in a broad sense, which can be ions, molecules...

AI Technical Summary

Problems solved by technology

[0004] Although the filter membrane disclosed in this patent can provide high-quality and safe drinking water for a long time, the structure of the filter membrane is too complicated to allow water to pass through quickly, and the separation speed is slow. Therefore, a low-resistance warp-knitted drinking water filter is designed. Material processing technology is very necessary
