Embodiment 1
[0025] A high-efficiency organic-inorganic composite filter material is made of negative ion fiber monofilament weaving and pressing.
[0026] The preparation method of described filter material is as follows:
[0027] Step 1, winding three negative ion monofilaments to form woven monofilaments, and weaving the woven monofilaments as warp and weft threads to form a woven net;
[0028] Step 2, put 10 braided nets into a closed environment and let it stand for 30 minutes, then extrude at a constant temperature for 20 minutes to obtain a prefabricated filter plate. The sealed environment is a mixed atmosphere of nitrogen and water vapor, and the volume ratio of nitrogen and water vapor is 5:2, constant temperature extrusion pressure is 3MPa, temperature is 110℃;
[0029] Step 3, hang the prefabricated filter plate in a muffle furnace for sintering at a constant temperature for 2 hours, put it into distilled water and cook for 10 minutes after cooling, take it out and dry it to o...
Embodiment 2
[0037] A high-efficiency organic-inorganic composite filter material is made of negative ion fiber monofilament weaving and pressing.
[0038] The preparation method of described filter material is as follows:
[0039] Step 1, winding 10 negative ion monofilaments to form woven monofilaments, and weaving the woven monofilaments as warp and weft threads to form a woven net;
[0040] Step 2, put 30 woven nets into a closed environment and let it stand for 60 minutes, then extrude at a constant temperature for 40 minutes to obtain a prefabricated filter plate. The sealed environment is a mixed atmosphere of nitrogen and water vapor, and the volume ratio of nitrogen and water vapor is 4:1, constant temperature extrusion pressure is 7MPa, temperature is 120℃;
[0041] Step 3, hang the prefabricated filter plate in a muffle furnace for sintering at a constant temperature for 5 hours, put it in distilled water for 20 minutes after cooling, and dry it to obtain the filter material. ...
Embodiment 3
[0049] A high-efficiency organic-inorganic composite filter material is made of negative ion fiber monofilament weaving and pressing.
[0050] The preparation method of described filter material is as follows:
[0051] Step 1, winding 6 negative ion monofilaments to form woven monofilaments, and weaving the woven monofilaments as warp and weft threads to form a woven net;
[0052] Step 2, put 20 woven nets into a closed environment and let stand for 560 minutes, then extrude at a constant temperature for 30 minutes to obtain a prefabricated filter plate. The sealed environment is a mixed atmosphere of nitrogen and water vapor, and the volume ratio of nitrogen and water vapor is 3:1, constant temperature extrusion pressure is 5MPa, temperature is 115℃;
[0053] Step 3, hang the prefabricated filter plate in a muffle furnace for sintering at a constant temperature for 4 hours, put it into distilled water and cook for 15 minutes after cooling, take it out and dry to obtain the f...
