Good Eficiency Polyester Needle Felt Dust Filter Bag

Good Eficiency Polyester Needle Felt Dust Filter Bag            PPS Needle Felt Filter Bag Introduction:   PPS Needle Felt Filter Bag adopet the PPS from the USA, Japan, etc., according to other production process of high temperature resistant filter felt, production and processing of filtering material, one of the main products for high temperature resistant filter material.   PPS punched felt filter bag’s fiber has strong full retention and intrinsic chemnical resistance,can keep good filtering performance in harsh environment, and reach the ideal service time.   PPS Needle Felt Filter Bag Advantages:
1. Operation Temp. 170 °C, Instant Temp.232 °C, melting point 285 °C, limit oxygen index 34-35.   2. Operaiton is in the conditions where oxygen content ≤ 15% .   3. The fiber is anti-acid, anti-alkali and anti-corrosion, can be applied in the operation environment which fuel containing Sulfur or gas containing sulfur oxides.   4. The occasion of containing mositure in the flue.   5. Under the condition where Temp. is 190-232 °c, air to cloth ration is up to 5:1 at online dust cleaning, and air to cloth ration is 6:1 at offline cleaning dust.   PPS Needle Felt Filter Bag Application Fields:   1. The fume and smoke treatment and particle removing system in metallurgy plant, alloy plant, steel works, moulding factories, fire-retardant factories and power stations. 2. Asphalt concrete mixture, cements, ceramics, building materials, lime and plaster. 3. Dust treatment, purification and collection in electronics, mining, foodstuff processing, flour and timber processing.      PPS Needle Felt Filter Bag Parameters:
