What is PTFE bag filter?
PTFE is the abbreviation of polytetrafluoroethylene, called “non-stick coating” and “easy to clean material” linear polymer. PTFE is a needle felt made of polytetrafluoroethylene fiber, and then processed into a bag filter. It has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of temperature resistance and low friction coefficient.
Advantages of PTFE bag filter
PTFE bag filter has excellent chemical performance stability and heat resistance, is the representative of the highest performance in the filter material industry, and is also the most high-end variety of all commonly used filter materials. The short fibers or filaments are oriented or strung to form a fiber mesh structure filter cloth, which is then processed by thermal adhesion and chemical methods. Used in chemical industry, paint and coating, resin, food and beverage, electronics, electroplating, medicine, etc. Acid and alkali resistance and high temperature resistance have reached a high level in filtration efficiency and filtration precision.
Features of PTFE bag filter
High temperature resistance – operating temperature up to 250 ℃.
Low temperature resistance – good mechanical toughness; Even if the temperature drops to – 196 ℃, the elongation of 5% can be maintained.
Corrosion resistance – for most chemicals and solvents, it is inert and resistant to strong acids and alkalis, water and various organic solvents.
Weather resistance – has the best aging life of plastics.
High lubrication is the lowest friction coefficient among solid materials.
Non-adhesion – is the minimum surface tension in solid materials and does not adhere to any substance.
PTFE bag filter application
The filtration of various medium-low viscosity fluids, such as petrochemical industry, automobile manufacturing, paint coating adhesive, paint, electronic technology, metal processing, water treatment, pharmaceutical, food and beverage, has excellent filtration effect for various types of impurities.
