Acrylic Needle Felt Dust Filter Bags
Acrylic Needle Felt Dust Filter Bags are a kind of dust filter bag. It is made of needle felt chemical called polyacrylonitrile. It is used as a raw material to make felt by acupuncture method, and then it undergoes special treatment to obtain acrylic medium-temperature hydrolysis-resistant needle-punched filter. felt.
Acrylic Needle Felt Dust Filter Bags have an air permeability of 14m3/m2•min, instant working temperature: 160℃, normal work 140℃, needle felt is reinforced with acrylic woven fabric as the base fabric.
Features of Acrylic Needle Felt Dust Filter Bags:
1. The working time of the dust-removing bag has a continuous working temperature of 140 degrees, and an instant does not exceed 160 degrees;
2. Good acid and alkali resistance, PH value is between 3-11.
3. The relative humidity is less than 30%, pay attention to oxidation.
