Example Embodiment

[0009] Example 1

[0010] The silver-loaded activated carbon fiber filament is connected to the fiber braiding machine, and the existing weaving technology is used to spun into a silver-loaded carbon braided tube, the spun silver-loaded carbon braided tube is taken out, and the spun silver-loaded carbon braided tube is connected to the wet process Spinning production line; using the existing braided tube membrane preparation technology, a layer of ultrafiltration membrane-forming liquid with a fluid viscosity of 4000mPas is coated on its surface through spinneret extrusion, and the coated braided tube is passed through a section of 30cm air After bathing, it is immersed in a water coagulation bath, and then it is drawn and taken up and washed with water to form an antibacterial hollow fiber membrane. The infiltration bonding layer formed between the functional layer on the surface of the membrane and the silver-loaded carbon braided tube is about the thickness of the silver-loaded...

Abstract

The invention discloses a preparation method of an antibacterial hollow fiber membrane. The method disclosed by the invention is carried out according to the following steps: (1) preparing silver-loading activated carbon fiber filaments into a hollow fiber braided pipe of silver-loading activated carbon fibers through an existing braiding technology, so as to obtain a silver-loading carbon braidedpipe; (2) carrying out surface coating on the obtained silver-loading carbon braided pipe by adopting a membrane forming material solution of an ultra-filtration membrane, wherein the coating and wetting depth is less than or equal to 2/3 of the wall thickness of the silver-loading carbon braided pipe; finally, immersing the silver-loading carbon braided pipe into water of a coagulating bath andcuring and forming. The hollow fiber membrane prepared by the preparation method integrates three effects including ultra-filtration separation, activated carbon adsorption and silver-loading bacterium resistance through the control of a spinning and membrane preparation technology and a membrane structure control; a technological flow of a water purification process is effectively shortened and various problems which are possibly generated in a matching process of all links are avoided.

Description

technical field [0001] The invention relates to the technical field of water treatment products, and more specifically relates to a preparation method of a hollow fiber membrane with antibacterial function suitable for drinking water treatment. Background technique [0002] With the development of household water purifiers, the requirements for its comprehensive functions are getting higher and higher. Household water purifiers usually need to be filtered by ultrafiltration membranes to remove impurities such as bacteria and colloids, then activated carbon to improve the taste, and then disinfected by ultraviolet light. Among them, activated carbon and ultraviolet light disinfection can also be replaced by silver-loaded activated carbon. Obviously, the degree of integration of this process is low, and the long process is prone to water leakage or other problems that affect water quality and safety due to problems in the connection of various links.
