Problems solved by technology

If you use it for a long time, you will find that the material will gradually become hydrophilic. Once hydrophilic, the air permeability will decrease.
At the same time, due to the production process and other reasons, the existing domestic gas filter membranes are bonded and compounded by hot-melt adhesives, which will not only affect the air permeability of the product, but also cause the hot-melt adhesives to be

Abstract

The invention discloses a processing technology of an air filtration membrane, which comprises the following steps: preparing the following substances by weight: polyethylene terephthalate, polypropylene, polyethylene, polyamide, cellulose acetate, cellulose acetate ethylene terephthalate, polypropylene, polyethylene, cellulose acetate, polyhydroxybutyrate Mix the acid copolyester and sodium dodecyl sulfonate, stir and mix the mixture again, and let stand for 1-2 hours in an environment of 40-45 degrees Celsius; the film is placed in an environment of 80-95 degrees Celsius and stand for 8-10 (8) After curing, it is lowered to room temperature and left to stand for 24 hours to obtain a filter membrane, which has good filtering effect, low cost and simple process flow.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a processing technology of an air filter membrane. Background technique [0002] Gas filter membranes are generally cloth filter papers, which can be made into capsule, folded, roll and other filter materials according to different applications. The existing gas filtration membrane filter layer materials mainly include: polypropylene (PP), polytetrafluoroethylene (PTFE), polyethylene (PE), polyvinylidene fluoride (PVDF), etc. The gas filtration membrane mainly includes substrate and filter The commonly used composite process is hot melt adhesive bonding, and its base material is mainly made of polypropylene (PP), polyethylene terephthalate (PET), polyethylene (PE) and other materials. spinning. [0003] Gas filter membranes are often used to clean gases in special environments, which often contain water vapor, oil, hydrophilized substances, impurities, etc. Due to the character...
