Comparison of Several Types of Dust Collecting Bags
The dust collecting bag is an important filtration element in the bag filter and is a consumable item that needs to be replaced regularly. With the promotion and application of bag filters in various industries, the types and varieties of the dust collecting bag are also increasing, but many customers often do not understand the performance of different dust collecting bags when purchasing them. Below we introduce the advantages and disadvantages of different dust collecting bags, convenient for customers to choose the appropriate ones according to their different working conditions.
1. Polyester dust collecting bag
Advantages: wear resistance, high strength, good ventilation, stable size and low price. Long-term use temperature below 120 °C
Disadvantages: not resistant to strong alkali, easy to hydrolyze
2. Acrylic dust collecting bag
Advantages: resistance to medium acid, resistance to weak alkali , long-term use temperature below 140 °C
Disadvantages: the use temperature range is between 140 °C and 170 °C, and the application field is smaller.
3. Aromatic polyamide (aramid) dust collecting bag
Advantages: good alkali resistance and temperature resistance. Long-term use temperature below 200 ° C
Disadvantages: general wear resistance, high price
4. Polytetrafluoroethylene (PTFE) dust collecting bag
Advantages: good performance of wear resistance, acid and alkali resistance, corrosion resistance and high temperature resistance, long-term use below 200 °C, high mechanical strength, can withstand high filtration wind speed (2.4m/min), high dust removal efficiency, not aging
Disadvantages: expensive
5. Polyimide (P84) dust collecting bag
Advantages: chemical corrosion resistance, excellent filtration performance, flame retardant, continuous operation below 240 °C.
Disadvantages: not resistant to hydrolysis, easy to corrode in a watery environment, expensive.
6. Glass fiber dust collecting bag
Advantages: high temperature resistance, corrosion resistance, smooth surface, no condensation, no shrinkage. Good ability to collect dust, high dust removal efficiency, moderate price, suitable for backflushing type of dust bag removal equipment
Disadvantages: poor resistance to folding and wear
