Introduction to High-Molecular Powder Sintered Filter Cartridges

1. PP (Polypropylene) Powder Sintered Filter Cartridges​

PP powder sintered filter cartridges are formed by heating polypropylene polymer particles at a temperature lower than their melting point, causing them to adhere to each other and create a stable porous structure. These cartridges exhibit excellent chemical stability and can resist the erosion of various chemical substances, maintaining good performance in both acidic and alkaline environments. Additionally, they have high thermal stability and can operate normally under certain high-temperature conditions, which makes them widely used in industries such as chemical engineering, food and beverage, and electronics manufacturing. For example, in chemical production, they are used to filter corrosive liquid raw materials; in the food and beverage industry, they can precisely filter production water to ensure it meets hygiene standards. Moreover, PP powder sintered filter cartridges have high mechanical strength and good durability. They can withstand certain pressure shocks, have a long service life, reduce the frequency of equipment maintenance and filter cartridge replacement, and save costs for enterprises.​

2. PE (Polyethylene) Powder Sintered Filter Cartridges​

PE powder sintered filter cartridges usually use ultra-high molecular weight polyethylene as the main raw material and are manufactured through scientific formulation and high-temperature sintering processes. Ultra-high molecular weight polyethylene endows the cartridges with better acid and alkali resistance than ordinary polyethylene, showing excellent corrosion resistance when dealing with strong acids and alkalis and other corrosive media. They also have excellent rigidity and flexibility, with good mechanical properties, and can adapt to complex working environments. The pore size distribution of PE filter cartridges is uniform, and the inner and outer pore sizes are the same. This feature ensures that impurities are less likely to remain inside the cartridge during the filtration process, and the back-blowing and slag-removing operations are convenient and efficient, greatly improving the regeneration performance and service life of the cartridges. In fields such as water filtration, air filtration, environmental protection sewage treatment, and reclaimed water reuse, PE powder sintered filter cartridges, with their characteristics of large flow and high porosity, ensure the efficient passage of fluids per unit area while maintaining the stability of the filtration effect. They are an ideal choice for filtration in large-flow working conditions.​

3. Glass Fiber Powder Sintered Filter Cartridges​

Glass fiber powder sintered filter cartridges are mainly made of glass fiber. Glass fiber has advantages such as high strength, high temperature resistance, and good chemical stability. After special sintering process treatment, the manufactured cartridges have very fine and uniform pores, enabling high-precision filtration and effectively intercepting tiny particle impurities. In industries with extremely high requirements for air quality and fluid purity, such as aerospace, electronics semiconductors, and precision instrument manufacturing, glass fiber powder sintered filter cartridges play a crucial role. For instance, in the air purification system of an electronics semiconductor production workshop, they can filter out dust particles in the air, providing a clean production environment for precision processes such as chip manufacturing; in the fuel filtration system of an aircraft engine, they can ensure the high purity of fuel, guarantee the stable operation of the engine, and avoid failures caused by impurities.​

4. PTFE (Polytetrafluoroethylene) Powder Sintered Filter Cartridges​

PTFE powder sintered filter cartridges are made of polytetrafluoroethylene material. Polytetrafluoroethylene is known as the “king of plastics” and has extremely excellent chemical inertness. It hardly reacts with any chemical substances and can resist the corrosion of strong acids, strong alkalis, and various organic solvents. This makes PTFE filter cartridges indispensable in industries such as chemical engineering and petrochemicals that involve the treatment of highly corrosive media. Meanwhile, it also has characteristics such as a low friction coefficient, good weather resistance, and self-lubrication. When filtering media with high viscosity or prone to scaling, the surface properties of PTFE filter cartridges can effectively prevent impurities from adhering, reduce the risk of cartridge blockage, and maintain stable filtration performance. In the pharmaceutical industry, PTFE filter cartridges are often used to filter corrosive liquids during the pharmaceutical production process to ensure that the quality of drugs is not contaminated; in the environmental protection field, they can be used to treat industrial wastewater containing complex chemical substances to achieve compliant discharge.​
