Problems solved by technology

[0002] At present, the known methods of purifying dust-laden gas through filter bags are usually inner filter type and outer filter type and are used alone, the filter area is limited, the equipment occupies a large area, and the cost is high
In order to improve the efficiency of filtration and purification, most of them adopt the method of increasing the filter area of ​​the filter bag. Generally, there are two methods: one is to increase the diameter of the filter bag; the other is to lengthen the length of the filter bag. The area is large and the cost is high. However, with the increase in the practical requirements of the filter bag, its temperature resistance and anti-degeneration are more and more important

Abstract

The invention discloses a high-temperature-resistant anti-deformation filter bag material. The high-temperature-resistant anti-deformation filter bag material is prepared from 20-30 parts of stainlesssteel fiber, 2-8 parts of fire retardant, 30-50 parts of polyurethane resin, 20-40 parts of epoxy-modified silicone resin, 5-8 parts of glass fiber, 2-4 parts of active agent, 1-3 parts of foaming agent, 2-6 parts of penetrant and 2-4 parts of stabilizer. The high-temperature-resistant anti-deformation filter bag material has the advantages that shuffling of the stainless steel fiber and the polyurethane fiber is adopted, and the high-temperature-resistant anti-deformation filter bag material has high-temperature-resistant and flame-retardant properties, is high in strength, light and thin, high in safety and good in durability.

Description

technical field [0001] The invention belongs to the technical field of filtration, and in particular relates to a high-temperature-resistant and deformation-resistant filter bag material. Background technique [0002] At present, the known methods of purifying dust-laden gas through filter bags are usually inner filter type and outer filter type and are used separately, the filter area is limited, the equipment occupies a large area, and the cost is high. In order to improve the efficiency of filtration and purification, most of them adopt the method of increasing the filter area of ​​the filter bag. Generally, there are two methods: one is to increase the diameter of the filter bag; the other is to lengthen the length of the filter bag. The area is large and the cost is high. However, with the increase in the practical requirements of the filter bag, its temperature resistance and anti-degeneration are becoming more and more important.
