Advantages of PTFE filter bags

PTFE dust bags are widely used with good results, especially in large high-temperature baghouse dust collectors are more commonly used. The glass fiber film filter media produced by this technology is used for dust removal, low running resistance, long life, no film shedding phenomenon, long-term working conditions at 260 degrees, all the performance of the dust bag is no change, the recovery of dust below 5um, the life of the dust bag under normal use will be more than 2 years.

PTFE dust bag material, the scientific name of polytetrafluoroethylene, known as "plastic king", is a polymerized polymer compound of tetrafluoroethylene that can withstand molten alkali metals, chlorine trifluoride, chlorine pentafluoride, and all chemicals other than liquid fluorine, boiling in water remains unchanged, widely used in a variety of occasions requiring resistance to acids and organic solvents.

Fiber form: Because of the different spinning methods, the fiber color is divided into white and brown. White fiber is purer, fiber shape is mostly flat type, and brown fiber will contain a small number of impurities, fiber shape is mostly round type.

PTFE dust bag has a fine pore size of 0.1-3.5μm, with a fine pore porosity of 75-90%. Such a high microporous porosity enables tiny water gas molecules to diffuse freely through the voids of the film, thus enabling a large amount of dense water vapor to pass freely. However, PTFE dust bags are extremely hydrophobic and water cannot pass through the microporous film. Due to its good performance with any chemical substance, PTFE dust bags can be used in various chemical production technologies.

PTFE bags have a range of excellent use properties:

　　High-temperature resistance: long-term use temperature 200 to 260 degrees.

　　Low-temperature resistance: soft even at -100 degrees.

　　Corrosion resistance: resistant to water and all organic solvents

　　High lubrication: smaller coefficient of friction in plastics (0.04 ).

　　Non-adhesive: non-adherent material with low surface tension in solid materials.

       High strength: the fiber is used as a base cloth, and the strength is basically guaranteed not to decay during long-term use.

　　Non-toxic: physiologically inert.

       Excellent electrical properties: it is an ideal class c insulating material, and the thickness of the newspaper can further shield the high voltage of 1500V.
