PTFE滤袋应用于强酸强碱等恶劣场合,是滤料工业化应用中高性能的代表,常用于化工,垃圾焚烧等行业
PTFE is a very chemically stable fiber. Its characteristics are as follows:
1. The continuous working temperature is above 250 ℃, and the instantaneous temperature is 280 ℃.
2, completely not afraid of acid and base and oxidation, almost non-flammable.
3. A fiber that doesn't age.
4. Meet the harsh working conditions and have a long service life, usually more than 4 years.
PTFE needled felt filter material is mainly used in chemical industry, waste incineration, high-temperature liquid filtration and so on. It maintains good chemical stability under various complex working conditions, but it is not suitable for wide use due to its high price.
