Normal temperature polyester dust removal cloth bag

  Polyester needle felt is widely used in environmental protection dust removal equipment
It is suitable for working at room temperature and can work continuously at 130 degrees
Post treatment methods include calendering, singeing, heat setting, immersion drying, coating, etc
It has the characteristics of stable size, easy ash removal and long service life

 
Polypropylene filter bag can be used in 90 degree humid environment with softening temperature of 150 degrees
Polypropylene fiber has good acid and alkali resistance, good strength and wear resistance

 
When the temperature of acrylic filter bag is lower than 125 ℃, it has good resistance to organic solvents, oxidants, inorganic and organic acids
Acrylic is not a self condensation polymer, which is often used to replace fibers with hydrolysis problems, that is, it is used in low temperature, humidity and chemical corrosion

 
The polyester needle punched filter felt of our company is made of 1-2
5d high-quality polyester fine denier yarn, weaving reinforced base cloth with high-strength and low elongation yarn, and then processed by needle punching reinforcement and post-treatment process
This product not only has the characteristics of high porosity, good air permeability, acid resistance and moderate alkalinity of ordinary felt filter cloth, but also has very good wear resistance
Therefore, it is the most widely used variety of felt filter materials
The gram weight ranges from 350g / m2 to 800g / m2, and the thickness ranges from 1mm to 4mm
Post treatment methods include calendering, singeing, heat setting, immersion drying, coating, etc
It has the characteristics of stable size, easy ash removal and long service life

The surface smoothness of filter material has a great influence on the dynamic running resistance of filter material
The initial resistance of the filter material depends on the air permeability of the filter material itself, and the resistance in operation is many times greater than the initial resistance
The running resistance depends on the smoothness of the filter surface and the ash removal effect
It is generally hoped that when the filter material ensures the same filtration efficiency, the greater the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy
In the dust remover using air flow back blowing for dust removal, when the air flow with the same pressure and air volume is used for dust removal, the dust removal effect of selecting the fabric with large air permeability as the filter bag is better than that of selecting the fabric with small air permeability
Therefore, under the condition of ensuring the high filtration accuracy of the filter material, how to improve the permeability of the filter material, improve the surface smoothness, reduce dust adhesion and reduce the running resistance is the first topic that the filter material manufacturer should study
The surface resin smooth finishing needle punched filter felt developed by our factory has an air permeability of more than 50% higher than that of ordinary calendering finishing filter material, and the surface smoothness is more flat and smooth than that of calendering finishing
