PP acrylic aramid PTFE membrane filter bags for aluminum smelting industry
#Aramid filter bags #Aluminum Electrochemical Smelting
Aramid products have the characteristics of high temperature resistance (204ºC-240ºC), strong acid and alkali resistance, high filtration wind speed, low pressure loss, folding resistance and good wear resistance, but they are not resistant to hydrolysis at high temperatures.
Product Features:
Advantages: good temperature resistance, high oxygen resistance, low shrinkage
Disadvantages: poor hydrolysis resistance, poor acid resistance
