350gsm 600gsm Needle Felt Filter Bags Singed And Calendered

Needle Felt Filter Polyester Filter Bag Singed And Calendered For Cement Industries


Product Description

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.

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.


Brief Parameters

Product details

1.Suture line: Use special lines to seal edges, flat end with triple seam.


2.Material and thickness: Recommand different proportion materials and thickness according to different uses.

3.Material performance: Acid alkali resistance, Abrasion resistance, Corrosion resistance. The filter bags use our material guarantee Filter Precision, so can meet your local government's emission stadard.


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.

Polyester fiber has good heat resistance, melting point is 255-265 ℃, burning temperature is 450 ℃, softening starts at 230-240 ℃, and the strength loss caused by heating at 170 ℃ for a short time can recover by itself. Therefore, polyester fiber has good practicality at normal temperature and can work continuously at 135 ℃, so it is the most cost-effective material at low temperature.
Polyester fiber has high strength, good elastic recovery performance, own the strength of 3.52-5.28CN / dtex, elongation at break can be upto 30% - 40%, fabric has size stability, high strength, good elongation, therefore, polyester fabric provide perfect wear resistance performance.
