Dust Collector Bags Polyester Filter Bag Air Bag Filter for Cement Dust Filter
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.

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 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 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.
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 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.
Application
For Cement Industry, we know that the cement producer all over the
world need high-performance filter media for kiln mill, alkali, and
other pulse jet or reverse baghouse. Our filter Bags provide
emissions control, production increases and the lowest overall
maintenance and operating costs.
For Chemical Industry, our filter bag for the chemical industry are
offered as thorough solutions.
For Power station and Incineration Industry, with PTFE membrane,
our filter bags provide near zero emissions for waste processing
and power station boiler. Whether you use standard or low grade
coals, wood or tires in your boiler, or operate a chemical,
hazardous, or waste incinerator, all we can deliver consistently
high airflow over the life of the filter bags for your application.
