Description
The membrane filter bag adheres to different needled felt surfaces by pressure and high temperature. When laminating with thermoplastic fiber felt, we use special surface treatment technology to treat the surface of the felt first, and then laminating with PTFE film. The non thermoplastic fiber felt must be treated with surface chemistry and Teflon before being clad with PTFE. In addition, some special fibers need special chemical surface treatment to achieve the strongest bonding effect.
The pore size of PTFE film ranges from 0.1 μ m to 3.5 μ m, and the porosity reaches 75-90%. Such a high porosity is enough to allow a large number of dense water vapor to pass through freely, because tiny water vapor molecules can diffuse freely and pass through the pores of the film. However, PTFE of vacuum is extremely hydrophobic, and water cannot penetrate through the microporous membrane. Because PTFE has excellent corrosion resistance to any chemical, PTFE film can be used in various chemical production processes.
Advantages of covered filter bag
The surface filtration is realized, and the dust emission is almost zero, which can meet the strict emission standards of various countries.
The best dust cake shedding performance, improve the ventilation of dust collection equipment, reduce the pressure drop of dust collection equipment.
The service life of the filter bag is prolonged, the ash cleaning cycle and power consumption are reduced, and the maintenance cost of the dust collecting equipment is saved.
Improve the filtering wind speed of dust collection equipment, reduce and reduce the use volume and investment cost of dust collection equipment.
Due to the low voltage drop of operation, the power consumption of dust collection equipment is reduced.
VABLUE reduces the total investment cost and operation cost of dust collection equipment, increases the production capacity and expands the product profit.
