With the development of various filtering technologies, filtering technology will gradually mature, and new filtering technologies will gradually appear. How to choose depends on everyone’s specific production situation. Keeping the air in the workshop clean is very important for some microelectronics companies or pharmaceutical companies. Today, the PTFE plate and frame filter membrane manufacturer will explain to you the common purification methods of workshop air filtration:
Workshop air purification method one: activated carbon adsorption. This filtration method mainly utilizes the porous characteristics of activated carbon. Activated carbon has a highly developed pore structure and, if fully opened, has a large surface area, which allows the activated carbon to fully contact the air. And adsorb the impurities in it. Because activated carbon has good filtration effect and is very cheap, many people use activated carbon in current workshops. Workshop air purification 2: HEPA net filtration HEPA (High efficiency particulate air Filter), which means high-efficiency air filter in Chinese. This filter is composed of a stack of PTFE composite materials that are continuously folded front and back to form a wavy gasket for placement and Support the filtering medium.
Polytetrafluoroethylene frame filter membraneThe surface morphology is a spider web-like microporous structure. Pores are formed between the microfibers, and the arrangement direction of the microfibers is basically parallel to the stretching direction; the junction of the fiber bundles is the node, which is formed by the entanglement of many microfibers. PTFE membrane is an asymmetric membrane, and the micropore size is different on the front and back sides of the membrane. The cross-sectional micropore size of the membrane is larger than the micropore size on its surface, and the vertical and horizontal micropore sizes are also different, with the longitudinal micropores being larger than the transverse ones. The cross-section of the membrane is a network structure. The three-dimensional structure of the pores has very complex changes such as network connectivity, pore nesting, and channel bending. There may be multiple micropores forming a channel, or one micropore may be connected to multiple Channels are connected.
The independently developed and produced polytetrafluoroethylene plate and frame filter membrane is the core material for HEPA filtering, with H13-U16 Different filtration levels, with hepa and ulpa level filtration efficiency, low wind resistance and low energy consumption, small and uniform pore size, high dust interception rate, up to 99.9995% or more, porosity up to 85% or more, high porosity, high breathability effect It also has a very good interception effect. Polytetrafluoroethylene plate and frame filter membrane The surface energy is low and the excellent non-adhesive properties allow dust on the surface to be easily removed. It is a manufacturer integrating production, sales and customization. The company has advanced PTFE film production lines and composite production lines. The company’s products are widely used in various fields, and it has a complete pre-sales, sales and after-sales service system. The products are deeply favored by customers.
