0.5 Micron Felt Seal Industrial Air Filter Polyester Filter Bags

Felt Seal Polyester Filter Bags With Anti Static Strip Hot Rolling For Mine Steel Food

Product Description
 
The filter bag is a key part of the operation of the bag filter. Usually the cylindrical filter bag is suspended vertically in the dust collector. The fabric and design of the filter bag should be as efficient as possible for efficient filtration, easy dust removal and durability.

We provide expert support not only filter bag design, but also how to optimize the flow parameters of your system to get the absolute best productivity. This process-specific product design and applications engineering approach has proven to be the best way to optimize your system's performance.

Structural Principle
 
Structural principle: Deep three-dimensional filter material, 100% pure fiber forms a three-dimensional, highly fluffy and tortuous three-dimensional filter layer by needle punching. It is characterized by loose fiber structure, which greatly increases the capacity of impurities.

During use, large particle impurities are trapped on the fiber surface, while fine particles are caught in the deep layer of the material, ensuring No damage due to increased pressure during the use, to guarantee a high filtration efficiency.
 
Characteristics of Polyester
 

Polyester is the most important filter material used in the manufacture of filter bags. Polyester fiber has a hygroscopicity of only 0.6% -0.8% when the relative humidity is 100% under standard conditions, Therefore, the fiber performance does not change much in dry or humid environments, and can provide good water resistance at normal temperature.

Polyester is acid-resistant and insoluble in organic acids. At low temperatures, it is very stable under low concentrations of inorganic acids and organic acidic solvents, but it can be dissolved in concentrated sulfuric acid.

Polyester is a polycondensation type polymer, and the macromolecule contains ester bonds, so it is not particularly resistant to strong alkalis at high temperatures.

The advantage of the PTFE membrane filter bag is that it realizes surface filtration. The principle is to trap the dust on the surface of the filter bag through the smooth microporous PTFE film, instead of forming a dust layer inside the filter material, so as to achieve surface filtration. And due to the smooth and waterproof properties of PTFE, the dust is not easy to adhere to the surface of the filter bag, make ash removal easy and effective. Moreover, PTFE membrane makes the filter bag own the characteristics of high temperature resistance and corrosion resistance.

The longitudinal seam of the body of the PTFE membrane filter bag is firm and straight, and it has a certain degree of flexibility during the dust removal and dust removal process. When making the bag body of the membrane filter bag, the method of longitudinal double-line sewing is used for sewing. The advantage of this method is that the elasticity and strength are better than the lock stitch. The three-needle sewing can make the strength of the filter bag be greatly enhanced.

Usually the fabric of the filter bag itself is not damaged, and the seam is split, the reason may be that the material of the seam does not meet the requirements, or the quality of the seam sewing is not close, or the seam form may be selected incorrectly.

 
Application
