What are the materials of glass fiber dust removal bag filter materials?

August 04,2023

1.Medium alkali glass fiber filter bag:

Made of medium alkali glass fiber twisted yarn material, it is divided into two series: graphite treatment and silicone oil treatment.

It is formed by continuous weaving of medium alkali glass fiber twisted yarn on a loom. Glass fiber filter material is an ideal filter material for high-temperature smoke and dust emission enterprises due to its high temperature resistance, good chemical corrosion resistance, and easy glass dust, Suitable for enterprises such as cement vertical kilns.

2.Alkali free glass fiber filter bag:

It is a filter material with excellent alkali resistance that is woven from twisted glass fiber yarn formed by chemical treatment of glass fiber yarn before weaving.

When encountering alkali containing gas in the equipment room, the alkali free glass fiber filter material is prone to corrosion due to its lack of alkali resistance, At this point, the alkali free glass fiber cloth woven from the alkali free glass fiber yarn with its own alkali resistance performance can fully adapt to the filtration of alkali containing flue gas, without the occurrence of filter material corrosion.

3.Alkali free expanded glass fiber filter bag:

Alkali free expanded glass fiber cloth is a new and efficient filter material developed on the basis of continuous alkali free glass fiber cloth.

Unlike continuous alkali free glass fiber cloth, its weft yarn consists of alkali free expanded glass fiber yarn. Due to the fluffy yarn, high coverage, and good breathability, it can improve filtration efficiency and reduce filtration resistance. Due to the good alkali resistance of alkali free glass fiber itself, it can effectively capture alkaline dust in flue gas. At this time, the filter material can effectively prevent alkali containing gas from corroding the filter material, thus keeping the equipment in normal working condition.
