涤纶三防针刺毡 —Polyester Tri-proof Needle Felt
Three anti-needle felt
- Continuous operation at temperatures below 120 ° C, good acid and alkali resistance. It is used in the field of dust removal and filtration with a flue gas temperature below 100 ° C or a weak acidity and alkalinity.
It has the characteristics of good dimensional stability, high strength and long service life, so it also has the unique advantages of low resistance and easy cleaning. In the fields of beneficiation, coal preparation, petroleum, chemical and other industries,
To filter small particles and ensure filtration, polyester tri-proof needle felt is far superior to traditional woven filter materials.
According to the special working conditions and dust characteristics of the cement plant, static electricity can be reduced by adding composite conductive materials to effectively reduce static electricity caused by friction: special chemical treatment is added on the basis of ordinary antistatic needle felts to increase "Oil" function, functional polyester needle felt has nano-waterproof and oil-repellent treatment, and has "lotus effect". The surface of the filter bag is not easy to penetrate after contact with water and oil. Material anti-static, anti-condensation, high dust removal efficiency, high strength, high sun clearance rate, small gas filtration resistance, suitable for high temperature occasions.
