Fiberglass needle punched felt is one kind of high temperature resistant filter material with reasonable structure and excellent performance, it could be high temperature resistant, anti-abrasion, stable size, little elongation shrinkage ratio, high intension, also ultimate fiber of felt layer fiber, three-dimensional micro porestructure, high porosity, small filter resistance to gas, it has higher speed and efficiency. Compared with other high temperature resistant chemical fiber felt, it has the advantages of lower price, higher temperature resistant. Glass fiber needle punched felt are widely used in the field of filtration of high temperature smoke, such as chemical, steel iron, melting, carbon black, electricity, cement etc and all kinds of filter bag.
Technical data if fiberglass needle punched felt
Type | Weight | Tensile strength | Break intensity | Air permeability m3/m2.min | Temperature resist | |
Warp | Weft | |||||
FGF-NP | 1000 | 1900 | 1900 | 3.63 | 8-15 | 300 |
FGF-NP | 850 | 1350 | 1580 | 3.50 | 8-16 | 300 |
Note when use:
1. the weakness of fiberglass is not break resistant, so do not touch hard metal when use;
2. do not rub when install and be careful to avoid being injured;
3. the temperature of the dust catcher should be higher than 80℃.
