    details

    The production of PPS coated needle felt is made separately according to a strict set of production technology. It is a PTFE microporous film stretched in the warp and weft directions. Apply pressure and high temperature to different needle felt surfaces. When bonding with thermoplastic fiber felt, we use special surface treatment technology to treat the surface of the felt first, and then cover it with PTFE film. Non-thermoplastic fiber felts are surface chemically and Teflon treated before being laminated with PTFE. In addition, some special fibers need to be surface treated by special chemical methods to achieve a strong bonding effect.

    The PTFE film has a micropore pore diameter from 0.1-3.5 μm, and the micropore porosity reaches 75-90%. Such a high microporous porosity is sufficient to allow a large amount of dense water vapor to pass freely, because the minute water vapor molecules can diffuse freely and pass through the voids of the film. However, vablue's PTFE is hydrophobic, and water cannot penetrate the microporous membrane. Due to the corrosion resistance of PTFE to any chemical, PTFE films can be used in a variety of chemical production processes.

    Advantages of PPS coated dust bag

    The surface filtration is realized, and the dust emission is almost zero, which can meet various strict emission standards.

    Good dust cake falling performance, improve the ventilation of the dust collection equipment, and reduce the pressure drop of the dust collection equipment.

    The service life of the filter bag is prolonged, the cleaning cycle and the power consumption are reduced, and the maintenance cost of the dust collection equipment is saved.

    Increase the filtering wind speed of the dust collection equipment, reduce and reduce the volume and investment cost of the dust collection equipment.

    Due to the low pressure drop in operation, the power consumption of the dust collection equipment is reduced.
