Fiberglass filter bag performance and characteristics

Fiberglass filter bag performance and characteristics

Fiberglass needle felt dust filter bag is a traditional filter material, but it's also one kind of widely used filter material for high temperature flue gas. According to different fiber glass contents, the fiberglass needle felt can be divided into C (alkali) glass fiber filter material and E (alkali) glass fiber filter material two categories.

Fiberglass needle felt dust filter bag is a reasonable structure, better performance of the filter material to glass fiber as raw material, with a needle to the comb after the chopped fiberglass felt for acupuncture, mechanical method to make the fiberglass , And the fibrous web between the felt glass and the reinforcing glass cloth are entangled with each other and the fibrous web is reinforced and the felt-like nonwoven fabric filter material is formed.

Fiberglass has  high temperature performance prominent,it  can work under 260 ℃ (alkali) / 280 ℃ (no alkali) temperature for long time. Instantaneous temperature up to 350 ℃. High strength, low expansion and contraction, and its tensile strength than all other natural, synthetic fiber should be high, excellent corrosion resistance, resistance to most of the acid (except hydrofluoric acid) corrosion. Glass fiber surface is smooth, filter resistance is small, is conducive to dust stripping. It does not burn, no deformation.


The glass fibers treated with different surface treatment agents have the advantages of softness, smoothness, hydrophobicity, anti-condensation and low shrinkage. Glass fiber with outstanding dimensional stability, high tensile strength, corrosion resistance, smooth surface, hydrophobic, easy to clean, good chemical stability, because of its low cost, when the user requirements are low, dust removal equipment The manufacturer also uses glass fiber to do the pulse bag filter.

As an air filter manufacturer, the fiberglass need felt we produce has better performance and better price, you can contact anytime.
