Features of pps filter bag:

1. The pps filter bag refers to the strip-shaped yarn branch with conductive function woven in the pps filter material fiber or base cloth, so that the entire PPS filter material has conductive properties. During use, electricity is guided to the dust collector box and the ground through the pps filter material to prevent explosion accidents caused by electrical sparks.

2. The characteristics of the pps filter bag are that it has a high allowable working temperature in the air (can work continuously at 240, and can reach 260 in a short time), and has high mechanical strength, rigidity and hardness in a high temperature environment, excellent Corrosion and hydrolysis resistance, excellent abrasion and friction resistance, good dimensional stability, excellent high-energy radiation resistance, good UV resistance, flame retardancy and excellent electrical insulation.

3. In view of the thermoplasticity of pps filter bags, our factory adopts imported automatic hot-melt technology to produce polyphenylene sulfide hot-melt bags. The bottom, sides and collars of pps filter bags are welded by hot-melt method, which avoids side leakage and fiber shedding caused by pinholes and uneven materials in traditional sewn filter bags. The high-precision wireless sewing filter bag adopts digital configuration multi-point welding equipment to ensure that the welding of each point is firm and consistent.

The quality of PPS filter bags is critical. Damage to the PPS filter bag is caused by the following conditions:

One case: The process of processing PPS filter bags and bag cages is very difficult

If the PPS filter bag and the dust bag are rusted, open, welded, have burrs, etc., the friction between the PPS filter bags will increase, and damage is likely to occur in a short time.

Two cases: flower plate deformation

If the flatness of the flower plate does not meet the requirement of two thousandths, and even the irregularity can be seen with the naked eye, it will directly affect the verticality of the bag cage. If the verticality of the bag cage is not enough, it will inevitably cause mutual friction between the PPS filter bags. In particular, the elastic steel ring in the PPS filter bag is likely to cause damage, resulting in leakage and damage to the PPS filter bag.

Three cases: deviation of the plate hole.

It should be known that as long as the deviation of the orifice of the flower plate causes the deviation of the flower plate to be 2-3 mm, the PPS filter bag cannot be installed in the given position, and the PPS filter bag cannot be installed.


Products are widely used in steel, cement, chemical industry, power plants, road construction, metallurgy, food processing and so on.
