Coated ptfe high temperature dust bag, coated non-woven bag

PTFE coated high temperature dust bag and  coated bag  are two common industrial filtration materials, which play an important role in various industrial production processes. Both of these products have excellent performance and wide application prospects.

PTFE coated high temperature dust bag is a kind of dust bag using polytetrafluoroethylene (PTFE) film as the surface treatment material. PTFE is a high polymer with excellent heat, corrosion and insulation. PTFE coated high temperature dust bag can still maintain good filtration energy in high temperature, high humidity, high corrosion and other harsh environments, and is widely used in chemical industry, metallurgy, electric power and other industries of flue gas treatment and dust collection.

The main features of  PTFE coated high temperature dust bag are:

High temperature resistance: It can be used for a long time in a high temperature environment of 260℃, and the instant temperature can reach 300℃.

2. Corrosion resistance: Good corrosion resistance to acids, alkalis, oxidants and other chemicals.

3. Low friction coefficient: smooth surface, not easy to adhere to dust, reduce the frequency of cleaning.

4. High filtration efficiency: microporous structure, effectively intercept small dust, improve filtration efficiency.

5. Long life: good mechanical strength and wear resistance, long service life.

Coated cloth bag is a filter material using cloth as a substrate and coated with one or more layers of plastic film on the surface. Cloth is a kind of nonwoven fabric, made of short fibers or filaments by hot melting or chemical bonding, with good air permeability, high filtration accuracy, low resistance. The film coated cloth bag has good filtration energy at room temperature and general corrosive environment, and is widely used in air filtration, liquid filtration and other fields.

The main  features of coated cloth bags  are:

Good permeability: Microporous structure allows gas and water vapor to pass through, reducing the pressure loss of the filter.

2. High filtration accuracy: can effectively intercept small dust and impurities, improve the filtration effect.

3. Low resistance: smooth surface, not easy to adhere to dust, reduce the frequency of cleaning.

4. Easy to clean: can be repeatedly cleaned and used to extend the service life.

5. Environmental protection: The cloth itself is degradable and meets environmental protection requirements.
