PTFE filter bag is a high-tech product with many excellent properties in the field of filtration.

1. Material properties

PTFE is a material with unique chemical stability. It is resistant to corrosion by almost all chemical substances, whether it is strong acid, strong alkali or organic solvent, it cannot cause damage to it. This enables PTFE filter bag to work stably in harsh chemical environments, greatly broadening its application range. Moreover, PTFE material has an extremely low surface friction coefficient, which makes it difficult for the surface of the filter bag to adsorb dust and impurities, thereby maintaining good filtration performance.

2. Filtration performance

PTFE filter bag has very high filtration accuracy. It can effectively intercept tiny particles and has excellent capture ability for dust with a particle size of submicron level. In high temperature environment, its filtration efficiency can still remain stable. For example, in the exhaust gas treatment of some high-temperature kilns, PTFE filter bag can continue to work at a high temperature of 200-260℃ to ensure that harmful substances in the exhaust gas are effectively filtered and meet strict environmental emission standards.

3. Physical properties

This filter bag has good flexibility and can adapt to the installation requirements of filtration equipment of different shapes and structures. At the same time, the PTFE filter bag has high strength and can withstand certain mechanical pressure and airflow impact, and is not easy to break. During long-term use, its dimensional stability is good and will not deform due to long-term stretching or contraction, thus ensuring the durability of the filtering effect.

4. Application Fields

PTFE filter bags are widely used in chemical, electric power, metallurgy, waste incineration and other industries. In the chemical industry, it is used to filter various corrosive gases; in the power industry, it is used to purify the smoke generated by coal-fired boilers; in the metallurgical industry, it is used to filter dust-containing gases generated during high-temperature smelting; in waste incineration plants, it effectively removes harmful particulate matter and dioxins and other pollutants generated by incineration.

PTFE filter bag has become an ideal choice in many industrial filtration scenarios due to its unique material properties, excellent filtering effect and wide applicability.
