introduction
PPS needle-punched filter material, also known as Polyphenylene Sulfide (PPS) needle-felt filter media, is a high-performance filtration material widely utilized in industries such as metallurgy, chemicals, building materials, thermal power, waste incineration plants, coal-fired boilers, and others, where it faces severe operating conditions involving high temperatures.
Product Features
- Corrosion Resistance: PPS fibers demonstrate superior resistance to organic acids, inorganic acids, acids, and oxidizing agents, outperforming other high-temperature-resistant fibers like NomexConex and Kermel fibers. This characteristic ensures a longer service life for PPS needle-punched filter material in corrosive environments.
- Flame Retardancy: With a limiting oxygen index (LDI) of 34-35, PPS fibers are non-flammable, possessing excellent flame retardant properties.
- Filtration Efficiency: PPS needle-punched filter material can undergo special treatments such as membrane coating to further enhance its filtration efficiency. For instance, PPS needle-punched filter material coated with Polytetrafluoroethylene (PTFE) film, featuring pore sizes around 0.23μm, can achieve filtration efficiencies exceeding 99.99%, virtually achieving zero emissions.
application area
- Building Materials Industry: In the production of building materials, PPS needle-punched filter material is used for purifying high-temperature flue gas, thereby improving product quality and production efficiency.
- Thermal Power Industry: Boiler flue gas from thermal power plants contains significant amounts of dust and harmful substances. PPS needle-punched filter material effectively captures these particles, protecting the environment and human health.
- Waste Incineration Plants: During waste incineration, high temperatures and corrosive gases are generated. PPS needle-punched filter material withstands these harsh conditions, ensuring the normal operation of incinerators.
- Coal-Fired Boilers: In the flue gas purification process of coal-fired boilers, PPS needle-punched filter material is highly favored due to its high temperature and corrosion resistance.
Customized filters of different specifications and models are available upon user's request.
