Embodiment 1

[0015] A hollow fiber manufacturing method of the present invention, firstly add 95-97 parts by weight of polyacrylonitrile monomer component liquid into the reaction kettle, then add 3-5 parts by weight of polymer material stock solution and stir, so that the two are fully reaction, followed by trace element purification and dross treatment, and then sent to another reactor to remove a large amount of foam generated during the process, and then add 2-10 parts by weight of sulfuric acid or hydrochloric acid, until the raw materials in the container react to paste When it is shaped, it is sprayed by a metering pump, and the diameter of the sprayed silk is about 1.6-2 mm; the sprayed silk is drawn with a drafting machine at a temperature of 180-370 degrees, and the fiber is drawn to a diameter of 10. -11 microns;

[0016] Then activate the obtained hollow fiber, treat the hollow fiber at a temperature of 180-790 degrees, and then spray water mist to the hollow fiber when the hol...

Embodiment 2

[0021] The difference between this embodiment and embodiment 1 is that the added amount of the sulfuric acid is 2-8 parts by weight.

Embodiment 3

[0023] The difference between this example and Example 1 is that the added amount of hydrochloric acid is 2.5-8.5 parts by weight.

[0024] The manufacturing method of the hollow fiber of the present invention is also applicable to the manufacture of hollow fibers of other polyester, nylon and other materials.

[0025] According to calculations, the cross-sectional area per gram reaches 3000-3500 square meters; the area expanded by the 3-gram hollow active fiber is as large as a football field, so it has an effect that is incomparable to any material.

[0026] The hollow fiber of the invention can be used as a filter material, and can also be made into paper for preparing fuel cells.

Abstract

The invention relates to a manufacturing method and application of hollow fiber. According to the manufacturing method, raw materials for preparing the fiber are added into a reaction kettle, so that the raw materials sufficiently take reaction, then, trace element purification machine slag processing is carried out, a great amount of foam generated in the removal process is removed, then, sulfuric acid or hydrochloric acid is added, after raw materials in a container react to a paste state, a metering pump is adopted for spraying to obtain hollow wires, the sprayed wires are heated to 180 to 370 DEG C, and then, a stretching machine is used for stretching; the hollow fiber is processed at the temperature being 180 to 790 DEG C, and then, water mist is sprayed onto the fiber when the fiber is not cooled, so that the fiber explodes to generate micropores. After the hollow fiber is activated, nanometer filtering materials are obtained, the popularization and the application to various fields can be realized, the materials are attractive in price and quality, the raw material resources are convenient, the acquisition is easy, the manufacturing process is mature and simple, the secondary processing and forming can be favorably realized, and the material belongs to a green environment-friendly novel filtering material capable of being easily recovered and can be continuously utilized.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a hollow fiber manufacturing method and application. Background technique [0002] The material revolution has brought about the continuous emergence of new products, and the continuous updating of new materials has provided the take-off of the industrial equipment manufacturing industry. The emergence of cutting-edge materials has brought new challenges to the manufacturing process technology. The application and demand of filter materials in the existing human industrial system has been rapid and extensive. There are several commonly used filter materials. 1. Water-washed anthracite filter material is made of high-quality anthracite coal from two mining areas in Jincheng, Shanxi and Jiaozuo, Henan. Processed by crushing, screening, and washing, the anthracite filter material is characterized by high fixed carbon content, high density, high strength, good appearance gloss, st...
