It has 3 types of needled felts; including pure glass fiber type, compound type with
blended glass fiber and synthetic fiber and synthetic type. It has three-dimensional
micro porous with high porosity and low resistance.
The dust separation efficiency is up to 99.9%, higher than that of woven fabric.
This product is suitable for bag filters with impulse jet or high velocity reverse
air clean-down technology. The compound glass fiber and synthetic fiber needled
felt is made of a certain amount of synthetic fiber blended into the felt.
Synthetic fiber has stronger interlocking capability. Compared with pure glass fiber
needled felt, the peeling strength between felt and base fabric and friction
resistance has increased 3 or 4 folds. Thus its service life is strikingly prolonged.
It is mainly used for cement and carbon black industries. The synthetic fiber
needled felt is made of P84 and PPS. It is mainly used for dust separation
of coal-fired boiler and precious metal recovery in non-ferrous metallurgy.
208 dust collector bags 729 dust collector filter bags are made of staple polyester fiber.It has good
intension,elongation and acid resisting.The dust collector bags is the ideal filtration material because of its good
permeability and ifficient dust filtration.The products can be widely used for oil refining,mineral,chemical
industry,environment protect,medicine field.etc.
