The fiberglass needle punched felt dust collector bag has the unique advantages of high porosity, good breathability, dust collection, and long service life of ordinary felt filter fabrics. Due to its moderate temperature resistance, up to 150 ° C, moderate acid and alkali resistance, and excellent properties, it has become a widely used variety of felt filter materials.

Glass fiber needle punched felt dust collector bag is a filter material with a reasonable structure and good performance. It not only has the advantages of glass fiber fabric, stable size, and low elongation and contraction rate, but also has a single fiber layer, a three-dimensional microporous structure, high porosity, and low resistance to gas filtration. It is a relatively high-speed and high-temperature filter material.

Compared with other chemical fiber felt, the fiberglass needle punched felt dust collector bag has the advantages of low operating resistance, high filtration and temperature resistance, and is suitable for high-temperature flue gas filtration in industries such as steel, metallurgy, carbon black, power generation, cement, and chemical industry.

The fiberglass needle punched felt dust collector bag can be used for sound insulation, shock absorption, and flame retardancy in the automotive industry, mainly for filtration in industry; Fiberglass needle punched felt is widely used for smoke purification and dust recovery in industries such as carbon black, steel, non-ferrous metals, chemical industry, and incineration.

Operating conditions of glass fiber needle punched felt dust collector bag:

1. The filtering wind speed should be less than 1.0m/min;

2. The working temperature of fiberglass needle punched felt should be less than 260 ℃.

Characteristics of glass fiber needle punched felt dust collector bag:

1. The fiberglass needle felt dust collector bag uses 90% fiberglass with a fiber diameter of 3.8-6um.

2. Reinforce the felt with a base fabric to ensure sufficient dimensional stability.

3. The felt layer has a three-dimensional microporous structure, with a porosity of up to 80%, which can achieve the above filtration effect.

4. After being treated with polymer compounds, the filter felt is endowed with excellent properties such as resistance to bending and damage.

5. 260 ℃.
