The material of dust removal bags in flour mills needs to have certain compressive, tensile strength, and wear resistance, as well as good anti-static and water resistance. Common materials for dust removal bags in flour mills include polyester fiber, acrylic fiber, PPS (polyphenylene sulfide), PTFE (polytetrafluoroethylene), etc. These materials have their own characteristics and should be selected according to the actual situation.
Polyester fiber bags have good breathability, water resistance, and chemical resistance, making them suitable for dust removal at low temperatures.
Acrylic fiber bags have excellent high-temperature and chemical resistance, making them suitable for high-temperature dry dust removal systems.
PPS cloth bags have good corrosion resistance, high temperature resistance, and long service life, and are suitable for dust removal of corrosive gases such as high temperature, strong acid, and strong alkali.
PTFE cloth bags have excellent high-temperature resistance, chemical stability, and adhesive resistance, making them suitable for dust removal scenarios with high temperature, high humidity, and corrosive gases.
