With the increasing intensity of national environmental protection, the requirements for enterprises to reduce emissions and pollution are also getting higher and higher, and the concept of green environmental protection is slowly taking root in the hearts of the people. receive constant attention. Environmentally friendly materials are accepted by the public because of their advantages in reducing air pollution dust and pollutants in sewage discharge.
Teflon bubble point membraneThere are two categories: hydrophilic and hydrophobic. PTFE liquid filtration membrane has the characteristics of surface filtration mechanism, small pore size and high porosity, and has a high flux that is difficult to achieve by other filtration membranes. Hydrophilic PTFE microporous filter membrane—replaces PES, N6, and PVDF filter membranes and is used for high-temperature liquid filtration with excellent biological safety, chemical inertness, low adsorption, and high temperature resistance. The pore diameter is 0.2um, with large flux, high strength, and does not fall off at high temperatures. It is suitable for filtration of strong acid and strong alkaline solutions, terminal sterilization filtration of medicinal liquids, filtration of high-temperature liquids, water treatment and environments where other filter materials are not competent.
With the rapid development of social economy, a large amount of industrial wastewater, domestic sewage and aquaculture sewage are discharged below standards, resulting in N, P organic matter and other pollution in water bodies. The substance content has greatly increased, resulting in serious eutrophication of the water body, reduced dissolved oxygen content, massive algae reproduction, and the water body becoming black and smelly, seriously damaging the ecological structure of the water body, affecting the ecological balance of the water body, and bringing serious consequences to human health and the growth of animals and plants. had a huge impact.
Teflon bubble point film is produced using advanced biaxial stretching technology and has a unique microporous structure. Micropores formed by billions of continuous interconnected filaments arranged non-concentrically and crosswise. It has the characteristics of breathable and impermeable, large air permeability, low resistance, high particle interception rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, aging resistance, non-stick, non-flammable and non-toxic, and biocompatibility. .
Teflon foam film has the characteristics of high power, easy cleaning, and washable. Surface filtration mechanism, small and uniform pore size, porosity up to 80%~90%, filtration efficiency up to 99.999995%. Teflon bubble point film has strong hydrophobicity, low surface energy, and good non-adhesion. It is easy to remove dust accumulated on the surface of the material, so it can be rinsed with water to restore its performance and achieve repeated use. Compared with other filter materials, it has a higher PF value and good filtering performance.
MBR is a new water treatment technology that combines a membrane separation unit and a biological treatment unit. It can perform solid-liquid separation well. The currently independently developed polytetrafluoroethylene flat membrane is the core component of the MBR membrane bioreactor. The membrane is prepared using a special biaxial stretching process and has low resistance. It is usually used in water treatment and raw water. Teflon foam membrane is the core filter material of MBR in the field of sewage filtration, with uniform pore size. It has high porosity and is a filter material with excellent performance. It has good chemical resistance, resistance to strong acids and alkalis, and high ozone strength. If you are interested, please enter the store for consultation.
