In the field of bag type dust, usually the heart bag compared to equipment, bag type dust collector can handle the dusty gas is mainly decided to chemical fiber fabric bags manufacturing conditions, general conditions of temperature, only need to bag can withstand temperature of 130°C. Such conditions with polyester at room temperature (needle felt, 729,208. acrylic) as the main body of the filter has basically can adapt to the situation, and for the relatively high temperature of flue gas industry needs to withstand high temperature chemical fibers are used to make filter which can fully meet the 150 to 250°C high temperature working conditions, MetaMax fiber due to the aromatic polyamide fiber, which has good heat resistance, abrasion resistance, folding, the folding properties is glass fiber can not be replaced.Technical parameter
