Description
PPS is called polyphenylene sulfide (PPS) in Chinese. The fiber raw material for the PPS needled filter felt produced by our company comes from the fiber
Procon (Toyobo), Torcon, Celanese, Fortron & reg (Toray) and PPS fiber (Sichuan Deyang Polytron Technologies Inc) and other famous enterprises home and abroad, the product has excellent thermal stability and flame retardancy, melting point of 285 DEG C, resistant to a variety of acid and alkali, can be used in damp, high temperature and chemical atmosphere under the condition of. PPS has a special requirement for the oxygen content in the filtered gas, and it is also closely related to the use of the temperature. It is widely used in coal fired power plant, municipal solid waste incineration, metal smelting, chemical industry and other low oxidation smoke dust removal.
* composite filtering materials may be formed with other fibers and base cloth according to the actual working conditions
【PPS needled filter felt】
Matters needing attention
1.The oxygen content is less than 14%.
2.Hydroxides are less than 600mg/Nm3;
3.The temperature should not exceed 180 degrees C;
4.The sulfur content is less than 2700mg/Nm3.
