Three-proofings filter material tensioned membrane

Abstract

The invention discloses a three-proofings filter material tensioned membrane, which comprises a PTFE microporous membrane, a fiberglass mesh layer, a glass fiber layer, a chemical fiber layer, a PTFE immersion treatment layer and a PET nonwoven fabric. One side of the fiberglass mesh layer is arranged on one side of the PTFE microporous membrane; one side of the glass fiber layer is disposed on the other side of the fiberglass mesh layer; one side of the chemical fiber layer is mounted on the other side of the glass fiber layer; one side of the PTFE immersion treatment layer is arranged on the other side of the chemical fiber layer; and one side of the PET nonwoven fabric is disposed on the other side of the PTFE immersion treatment layer. By arranging the PTFE microporous membrane, the fiberglass mesh layer, the glass fiber layer and the chemical fiber layer, seepage force of the tensioned membrane is guaranteed and impurity permeation is prevented; by arranging the PTFE immersion treatment layer for immersion treatment, blocking is prevented; and on the other hand, by arranging the PET nonwoven fabric and coating the outer wall of the PET nonwoven fabric with a high-temperature resistant coating, the tensioned membrane is prevented from being melted at high temperature.

Description

technical field [0001] The invention relates to a pulled film, in particular to a three-proof filter material pulled film. Background technique [0002] With the development of industrialization, a large amount of domestic and industrial waste water is discharged into water bodies, which makes the water sources that human beings rely on increasingly polluted. On the other hand, the fresh water sources available on the earth are becoming more and more scarce. There are more and more cities, and governments of all countries hope to improve the utilization rate of existing water resources through advanced treatment and reuse of industrial and domestic wastewater. Membrane separation technology has been gradually popularized and applied because of its advantages of high separation efficiency, simple equipment, convenient operation, no phase change and energy saving. The common filter membrane is generally a hollow fiber membrane. Its structure generally includes the filter memb...

AI Technical Summary

Problems solved by technology

The common filter membrane is generally a hollow fiber membrane. Its structure generally includes the filter membrane body, and a through hole is opened in the length direction of the filter membrane body. This kind of membrane is relatively fragile. And breakage occurs, the service life is shorter

And the filter membrane in the prior art, because it is a single-hole structure, the filter channel area is small, the filtering effect is not ideal, and this single-hole structure strength is low, and the pressure resistance is weak, and broken wires are prone to occur during use. Happening
