Polyester needle felt is a fine fiber cloth which adopts a non-woven needle punching process and uses fiber staggered and uniform void distribution. The surface of the needle felt produced by polyester staple fiber and polyester crepe is hot rolled, singeed or coated. After treatment, the surface is smooth and not easy to be blocked by dust. The filter material has large void ratio, good gas permeability, wide application, strong chemical stability, not only filtering normal temperature gas, but also filtering acid and alkali. Corrosive gas, and can filter water, filter oil, is normal temperature conditions. Ideal filtration materials in the fields of liquid-solid separation.
Product description Product description
PPS needle-punched filter felt is made of imported 100% PPS fiber. PPS fiber has excellent acid and alkali resistance and oxidation resistance, wear resistance and folding resistance.
Normal temperature resistance up to 180 ° C, short-term up to 210 ° C, suitable for thermal power, waste incineration, coal-fired boilers and other high sulfur containing flue gas filtration.
P84 needle felt is made of three-dimensional needles made of P84 fiber (ie, polyurethane fiber) produced by Austrian LENZING company. It has good high temperature resistance, temperature resistance up to 280 °C, and P84 fiber section is irregular. Shape, can greatly improve the filtration effect, the fiber itself has certain resistance to hydrolysis and oxidation. The product has good temperature resistance and good filtration effect, and is widely used in complex conditions such as concrete mixing, cement, garbage incineration, coal-fired boilers, etc. Use under conditions.
Generally, when the concentration of industrial dust reaches a certain level (ie, the explosion limit), in the case of static discharge sparks or boundary ignition, it is easy to cause explosion and fire. Such as: flour dust, chemical dust, explosive dust and so on. In the case of electrostatic discharge, there is an explosive nature. In the field of bag dust removal, if these dusts need to be collected by cloth bags, the bags themselves are required to have anti-static function. In addition to the production of ordinary needle felt process, the production of anti-static filter materials also requires the production of needle felts. The conductive fiber yarn is incorporated into the warp of the base fabric.
