[0028] See figure 1 , The filter material includes the first mixed layer 1 obtained by mixing bamboo fiber with 4080 and hot pressing and forming, and also includes a polytetrafluoroethylene microporous film 2 attached to the first mixed layer 1 by hot pressing.
[0029] The thickness of the polytetrafluoroethylene microporous membrane 2 is less than or equal to 3 microns.
[0030] The thickness of the first mixed layer 1 is 0.35 cm to 0.52 cm.
[0031] A manufacturing method of filter material includes the following steps:
[0032] Step 1: Send one end of the rolled first mixed layer 1 between the upper roller and the lower roller of the hot press;
[0033] Step 2: Place one end of the rolled PTFE microporous membrane 2 on the surface of one end of the first mixed layer 1;
[0034] Step 3: Start the hot press, and with the rotation of the upper roller and the lower roller, the polytetrafluoroethylene microporous film 2 is closely attached to the surface of the first mixed layer 1.

no. 2 example
[0041] See figure 2 In this embodiment, the method for manufacturing the filter material further includes step four, sending one end of the first mixed layer 1 attached with the polytetrafluoroethylene microporous membrane 2 obtained in step three into the hot press Between the upper roller and the lower roller of the machine, one end of the second mixed layer 3 is sent between the upper roller and the lower roller of the hot press, and the PTFE microporous film 2 is located in the first mixed Between layer 1 and the second mixed layer 3; start the hot press, with the rotation of the upper and lower rollers, the PTFE microporous film 2 is closely attached to the surface of the first mixed layer 1 and the first Between the surfaces of the two mixed layers 3.
[0042] In this embodiment, a first mixed layer 1 and a second mixed layer 3 are respectively provided on both sides of the polytetrafluoroethylene microporous membrane 2. The first mixed layer 1 and the second mixed layer ...
no. 3 example
[0046] See figure 2 In this embodiment, the filter material also includes a second mixed layer 3 obtained by mixing bamboo raw fiber with 4080 and hot-press forming, and the polytetrafluoroethylene microporous membrane 2 is sandwiched between the first mixed layer 1 and the second mixed layer 3.
[0047] The thickness of the first mixed layer 1 and the thickness of the second mixed layer 3 are 0.35 cm to 0.52 cm, respectively.
[0048] A manufacturing method of filter material includes the following steps:
[0049] Step one, send one end of the first mixed layer 1 and one end of the second mixed layer 3 into the roll between the upper roller and the lower roller of the hot press; one end of the first mixed layer 1 and the second One end of the mixed layer 3 is crimped together;
[0050] Step 2: Insert one end of the rolled PTFE microporous membrane 2 between one end of the first mixed layer 1 and one end of the second mixed layer 3, and place one end of the PTFE microporous membran...
