The advantages of PTFE coated filter bags mainly include high filtration accuracy, high temperature resistance, corrosion resistance, long service life, and economy. Its core application areas are industrial dust removal and flue gas treatment.
core advantage
1. High filtration accuracy
The PTFE coated filter bag is designed with a microporous structure for high filtration accuracy.
2. High temperature resistance performance
PTFE molecular chains remain stable at high temperatures of 260 ℃ and are suitable for high-temperature conditions such as waste incineration and coal-fired power plants.
3. Corrosion resistance
PTFE has low surface energy and is almost not affected by acid and alkali corrosion. Its service life is more than three times longer than ordinary filter bags in the treatment of hydrofluoric acid containing tail gas.
4. Longevity and Economy
The service life can reach 3-8 years, and the total lifecycle cost is lower than traditional filter bags, with reduced maintenance costs.
5. Environmental adaptability
Maintaining 99.99% filtration efficiency in an environment with 80% humidity, suitable for high dust concentration scenarios such as steel plants and cement plants.
Application field
Industrial dust removal: high dust environments such as cement plants, steel plants, and waste incineration plants.
Flue gas treatment: Treatment of tail gas containing hydrofluoric acid in coal-fired power plants and chemical enterprises.
Adverse working conditions: high temperature, highly corrosive gas environment.
