preparation example Construction

[0048] The preparation method of the antibacterial reverse osmosis membrane support body comprises the following steps:

[0049] a. Weaving: Use polyester long fibers to weave into gray cloth on a warp knitting machine;

[0050] b. Shaping: Carry out high-temperature shaping to the gray cloth through a shaping device, the shaping temperature is 160-200°C, and the speed is 20-26m / min; in this embodiment, the shaping temperature is 180°C, and the speed is 24m / min;

[0051] c. Padding finishing liquid: make finishing liquid, arrange the shaped embryos in the padding device for padding finishing liquid;

[0052] d. Finishing: first pre-bake the padded gray cloth at a temperature of 95-105°C for 5-8min, then bake at a temperature of 110-118°C for 3-8min, then wash with water, and finally dry to obtain antibacterial Reverse osmosis membrane support body: In this embodiment, firstly, the padded gray cloth is prebaked at a temperature of 100° C. for 6 minutes, and then baked at a tem...

Abstract

A preparing method of an antibacterial reverse osmosis membrane support body is provided. The method overcomes technical problems that present production processes are too simple, and require repeated manual operation, complex operation, and the like. The method includes a) a weaving step, namely a step of weaving dacron long fibers into a blank cloth through a warp knitting machine; b) a setting step, namely a step of subjecting the blank cloth to high-temperature setting through a setting device, with the setting temperature being 160-200 DEG C and a vehicle speed being 20-26 m / min; c) a finishing liquid padding and rolling step, namely a step of preparing a finishing liquid, putting the set blank cloth into a padding and rolling device and performing padding and rolling in the finishing liquid; and d) a finishing step, namely a step of firstly pre-drying the padded and rolled blank cloth at 95-105 DEG C for 5-8 min, then drying the blank cloth at 110-118 DEG C for 3-8 min, then washing the blank cloth with water and finally drying the blank cloth to obtain the support body. The method has an advantage of simple operation.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method of an antibacterial reverse osmosis membrane support body. Background technique [0002] The principle of reverse osmosis technology is to separate these substances from water based on the fact that other substances cannot pass through the semi-permeable membrane under the action of the osmotic pressure higher than the solution. The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. It has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation. [0003] After searching, for example, Chinese patent literature discloses an enhanced anti-pollution reverse osmosis membrane support material and its production process [application number: 201610047867.1; publication number: CN105536540A]. This enhanced ...
