ECOGRACE Fiberglass Filter Bag Chemical Finishing :
GSP finished:It consists blend of silicon oils, graphite & PTFE . The three finishes components combine to protect the glass fabric from abrasion , but offer only limited protection from chemical attack. The GSP finish is now widely primarily in cement production and metal foundry applications .
PTFE finished:10 % add-on of PTFE particles encapsulates the glass fibers to prevent abrasion.Recommended for use with utility base load boilers operating under mild pH conditions.
Acid Resistent treatment ( AR ) :Consists of acid resistant polymers,PTFE , graphite , and silicon treatment . Recommended for filtration of flue gases in industrial utility boilers and acid environments such as carbon black and fossil fuel burning power generation .
e-PTFE membranes: Coated with e-PTFE membranes
With the surface finished, it enjoys such characters as smooth, much lower emission , high temperature resistant , chemical corrosion repellent , high tensile breaking strength ,easy cleaning .
Fiberglass Dust Filter Bag Advantages :
1. Good Temperature-Resistance. Max. Temp. 280 degree C.
2. High Filtration Efficiency: up to 99.9%
3. Excellent performance in Anti corrosion.
4.Fiberglass filters is the first choice for incinerator smoke , smoke in industries like metallurgy, cement , carbon black, liquid boiler, coal fire boiler.
5. Longer working time: more than 36 months.
6. Variety of finish treatments : Coating PTFE Membrane ,PTFE Impregnation
7. Good heat resistance, flame retardant, anti-corrosion effect.
8 . Used in dust filtration of high temperature, high acidity, high alkalinity, fine high
temperature, collection of valuable metal powder , high adhesive property etc.
9. . Customized by order.
With rich practical experience and working R&D team, we can design and develop kinds of filter media to satisfy the complex and diverse working conditions.
10. Advanced production lines: Complete testing and testing methods are the assurance to the products' quality.
