The Nomex filter bag is made of fibers produced by DuPont and Teijin of the United States, and is compounded by a certain amount of acupuncture. Compared with ordinary filter materials, this product also has the following characteristics:
1. Excellent high temperature resistance: continuous operation at 190 °C, instantaneous working temperature up to 220 °C;
2, high dimensional stability: only 1% expansion rate at 220 ° C high temperature, with excellent high temperature stability;
3, fire retardant performance: at 400 ° C began to decompose carbonization, the limit of oxygen index (LOI) is 30, not spontaneous combustion does not support combustion;
4, good chemical corrosion resistance: acid and alkali resistance is not easy to corrode.
