High-temperature-resistant polytetrafluoroethylene material filter material base cloth

Abstract

The invention discloses a high-temperature-resistant polytetrafluoroethylene material filter material base cloth, which comprises a base cloth body. The high-temperature-resistant polytetrafluoroethylene material filter material base cloth has the advantages that by arranging a first polytetrafluoroethylene weaving layer and a second polytetrafluoroethylene weaving layer, alkali resistance and acid resistance of the overall base cloth are guaranteed, and high-temperature resistance, low-temperature resistance, non-stickiness and the like are achieved; the first polytetrafluoroethylene weavinglayer and the second polytetrafluoroethylene weaving layer are provided with a plurality of ventilating small holes correspondingly, and thus air circulation in the overall base cloth is facilitated;by arranging a first bamboo fiber yarn weaving layer and a second bamboo fiber yarn weaving layer, good performance such as good gas permeability and instantaneous water absorbability, and high abrasion resistance, antibacterial and bacteriostatic properties, deodorization property and ultraviolet prevention are achieved; by arranging a polytetrafluoroethylene mesh weaving layer, the first bamboofiber yarn weaving layer and the second bamboo fiber yarn weaving layer are layered; and by arranging a fluorocarbon resin film layer, it is guaranteed that when the surface layer is affected by the outside, performance such as non-stickiness and self-cleanliness can be maintained, overall environmental protection is achieved, practicality is high, and the high-temperature-resistant polytetrafluoroethylene material filter material base cloth can be applied to more fields.

Description

technical field [0001] The invention relates to a filter material base cloth, in particular to a high temperature resistant polytetrafluoroethylene material filter material base cloth, which belongs to the field of filter material base cloth production. Background technique [0002] The rapid development of industry has brought serious environmental pollution problems. A large amount of smoke and dust and toxic and harmful gases are emitted in industrial production, resulting in the concentration of suspended particulate matter in the air exceeding the standard, causing serious harm to air quality and human health. One of the means of industrial dust, the filter material is the core of the bag filter. The main material of the filter material is the base cloth of the filter bag. The base cloth plays a strong supporting role in the filter material. For general binding and spunlace felt filter materials, the base cloth plays a role of 70-80% in the warp and weft direction of th...

AI Technical Summary

Problems solved by technology

The main material of the filter material is the base fabric of the filter bag, and the base fabric plays a strong supporting role in the filter material. For general binding and spunlace felt filter materials, the base fabric plays a role of 70-80% of the strength of the material in the warp and weft directions. The strength of the traditional base cloth material is average, and it has poor aging resistance, weather resistance, low corrosion resistance, and short service life. The filter base cloth is often used for dust removal, filtration, etc., and requires good filtering function and anti-corrosion during use. Tensile strength, easy deformation and non-durable filter base cloth will cause a lot of inconvenience in use, need to be replaced frequently, increase labor and cost, the existing filter base cloth has poor wear resistance, weak antibacterial ability, and long service life Short, and dirt is easy to hide in the gap, and the gap in the fabric will gradually increase
