208 polyester fleece is currently an ideal dust removal filter, with good ventilation, high dust removal efficiency, and certain acid resistance, alkali resistance and heat resistance. Multilateral brushing is used in the weaving process, which increases the thickness of the fabric and is highly elastic. Therefore, the dust removal effect is good, and the dust removal rate can reach 99.99%.
208 polyester dust bag is widely used in petroleum, chemical, metallurgy, mining, cement and environmental protection dust removal industries.
The main technical parameters of 208 polyester dust bag are as follows:
1. Dust removal efficiency: 98.5%, up to 99% during operation;
2. Heat shrinkage rate: 3-5%;
3. Acid resistance: 35% hydrochloric acid, 75% sulfuric acid, and 60% nitric acid have no effect on its strength;
4. Alkali resistance: 10% caustic soda solution, 28% ammonia water does not change its strength;
5.Temperature resistance: Continuous use of 140 ～ 160 ℃, no less than 180 ℃ (dry heat);
6. Softening point: 238-240 ° C, melting point: 255-260 ° C.
