Fiber glass filter fabric and filter bags for industrial dust collection
Introduction of fiber glass filter fabric and filter bag:
Zonel brand fiber glass filter fabrics are made of E-fiber glass filament/E-fiber glass bulked yarn with some special finish treatment after the weaving works according to the different working conditions to make the glass fiber filter cloth with a much better flexibility, abrasion resistance and also suitable to be used in some special chemical circumstances besides the high temperature so as to prolong the service life of the fiberglass dust filter bags.
Zonel Filtech provide both the fiber glass filter fabric rolls and ready-made fiber glass dust filter bags, we also offer the free consulting to our clients to help them to get the most suitable fiber glass dust filter bags for their bag filter houses, as well as the relevant filter bag supporting cages and the accessories of the purging systems, etc.
For helping our client to reduce the emission rate, we developed the low resistance & high efficiency PTFE laminated fiber glass filter bag, the emission rate can be less than 5mg/Nm3, which keep the perfect performance for cement industry (Fiber glass filter bags for cement kiln exhausting dust air serial), metallurgy industry and some other high temperature dust air purification circumstances.

Properties of the fiber glass filter bags from Zonel Filtech:
1. the high tensile strength:
The tensile strength of the fiber glass filter fabric is more than 4000N/50mm as usual, which is much higher than chemical fiber filter materials and the blended filter materials, that is very suitable for the long filter bags sewing.
2. Anti-corrosion:
Fiber glass filter bag can keep a good performance in the circumstance of acid and alkali (except the hydrofluoric acid and strong phosphoric acid).
3. Stable size:
Under the high temperature (280~300 degree C), the elongation of the filter bag not exceed 2%, this property means they are suitable for the long filter bags sewing, and they won’t change the shape under the high temperature(280~300 degree C).
4. After some special treatment, with a very good water and oil repellent, easy cake release.
5. Anti-hydrolysis.
6. High temperature resistance, can work continuously understand temperature of 260 degree C.
7. Great Oxidant resistant, break the limitation of the PPS fiber in some extreme circumstance (acid and alkali) but no need to concern much on the oxygen content.
8. Lower price when compare to some similar temperature resistance chemical fiber filter materials.
9. High filter efficiency:
The fiber glass filter fabric with PTFE membrane treatment, the open size is lower than 1 micron, most of the particles only can touch with the membrane and can’t insert into the filter fabrics, not easy to be blocked and with a higher service life; at the meantime, the fiber glass with PTFE membrane treatment, the filter efficiency can up to 99.999%, can meet the strict emission requirements.
The applications of the fiber glass filter cloth and filter bags from Zonel Filtech:
1. steel plants (for purifing the gas from blast furnace, arc furnace, furnace of calcium carbide,etc.)
2. mechanical industies (for collection the fume and dust mainly from iron cupola,etc)
3. non-ferrous metal metallurgy (for collection the fume and dust such as from Zinc Fractionating tower,etc.)
4. cement plants (for collection the dust from the raw mills, verticle kiln, circumgyrate kiln, white cement kiln, dryer, cement grinding mills, etc)
5. Chemicals processing (for collection the dust from the dryers and micronizers in TiO2 and pigment industries, etc.)
6. Power generation and incineration industries.
