The product features of PPS high-temperature and acid alkali resistant needle punched filter felt dust bag:

1. Good temperature resistance with a melting point of 285 ℃, continuous use temperature of 190 ℃, and instantaneous use temperature of 230 ℃.

2. Excellent corrosion resistance: Polyphenylene sulfide fiber is superior to fibers in terms of resistance to organic acids, inorganic acids, acids, oxidants, and other factors.

3. The extreme oxygen index (LDI) of flame-retardant polyphenylene sulfide fiber is 34-35, making it a non combustible material. Polyphenylene sulfide fiber needle punched felt not only has high temperature resistance, but also unique corrosion resistance.

Application of PPS high-temperature and acid alkali resistant needle punched filter felt dust removal bag:

PPS high-temperature and acid alkali resistant needle punched filter felt dust bag is widely used in industries such as smelting, chemical, building materials, thermal power, waste incineration, coal-fired boilers, etc. under harsh high-temperature working conditions. It is a high-quality and efficient high-temperature resistant filter material. Our company uses polyphenylene sulfide fiber and specializes in producing polyphenylene sulfide (PPS) needle punched felt according to other high-temperature resistant needle punched felt production processes. The product quality reaches the level of similar products in developed countries abroad.

The performance advantages of PPS high-temperature and acid alkali resistant needle punched filter felt dust bag:

1. Good hydrolysis resistance, even after continuous use for 500 hours at 160 ℃ and 79% relative humidity.

2. The effect of easy cleaning of ash can be achieved through singeing and calendering treatment.

3. Heat resistance: It has a high melting point of 285 ℃, making it particularly resistant to long-term heat. It can be used continuously at a temperature of 190 ℃ and has extremely strong resistance to steam heat; Even in high-pressure steam at 160 ℃, it can maintain 90% strength.

4. Chemical resistance: Its outstanding chemical resistance is comparable to that of fluorinated fibers. At temperatures of 200 ℃ or below, it can maintain stable chemical resistance to most acids (except for a few oxidants such as concentrated nitric acid), alkalis, and organic solvents.

5. Mechanical properties: It is essentially the same as polyester in terms of strength, elongation, and elasticity.

6. Flame retardancy: It exhibits extremely high flame retardancy and self ignition (LOI limit oxygen index 34-35).

7. Radiation resistance: The tolerance to radiation such as λ rays and neutral rays is significantly improved compared to traditional nylon and polyester.

8. Electrical characteristics: Under high temperature, high humidity, and high frequency conditions, PPS fibers continuously exhibit stable electrical characteristics, complete strength retention, and inherent chemical resistance, which can maintain good filtration performance in harsh environments and achieve ideal service life. In pulse cleaning dust collectors for filtering coal boilers, garbage incinerators, and power plant fly ash, it can be said that bag filters with temperature and corrosiveness can be selected with appropriate PPS high-temperature filter bag felt for different temperature requirements.
