Embodiment 1

[0014] An air purification filter material, using PET or PPS base cloth, spun or mixed with an activated carbon fiber felt layer, then blended with a non-woven fabric layer and needle-punched, and finally blended with a PTFE microporous membrane on the non-woven fabric layer , Adhesive mesh polytetrafluoroethylene membrane layer above the PTFE microporous membrane. The PET or PPS base cloth is the nanofiber layer.

[0015] Activated carbon fiber carbonization treatment is required before using the activated carbon fiber felt layer. The treatment process is to place the activated carbon fiber in a low-temperature heat treatment furnace. The low-temperature heat treatment furnace starts to heat up from 120 ° C, and the temperature is increased by 4 ° C per minute, and the temperature is raised to 250 ~ 300 ° C. Then keep the temperature for 6 minutes, then cool down to a temperature lower than 70°C, and seal the inlet and outlet of the low-temperature heat treatment furnace with...

Abstract

The invention provides a filter material for air purification. PET (polyethylene terephthalate) or PPS (polyphenylene sulfite) base fabric is adopted, an activated carbon fiber felt layer is spun or mixed and laid, needling composition is performed after blending of the base fabric with a non-woven fabric layer, finally, a PTFE (polytetrafluorothylene) micro-porous film is blended on the non-woven fabric layer, and a netted PTFE film layer is bonded to the PTFE micro-porous film. Through cooperative use of the PET or PPS base fabric and the activated carbon fiber felt layer, the relative cost is lower, oxygen resistance of the material is enhanced and the impact strength is high due to the PPS base fabric, and functions of the filter material are enhanced and the washable performance of the material can be improved due to the PTFE micro-porous film. The filter material is high in filter efficiency, low in running cost, capable of removing other harmful chemical substances in the air, long in service life, easy to regenerate and free of secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to an air purification filter material. Background technique [0002] Air purification filter material is a relatively mature invention, but PM2.5 is an air treatment problem that needs to be solved more. For fine particulate matter, "PM2.5 refers to particles with a smaller particle size." Among the particulate matter floating in the atmosphere, use a device that can separate particles with a particle size of 2.5 microns at a rate of 50%, and remove larger particles. "Particulate matter collected after particulate matter". Although it also contains particles with a particle size larger than 2.5 microns, it roughly refers to particles with a particle size below 2.5 microns, and there are several components of 0.3 to 0.5 microns. [0003] When the PM2.5 index is hundreds or thousands, it is necessary to examine the breathing environment. It has reached the level...
