The glass fiber needle punch felt filter bag is the traditional main filter material in the bag filter, and is a weaving process. The glass fiber needle felt is woven into different textures through the processes of twisting, warping, weaving, and dyeing. Plain, twill, satin fiberglass cloth. The filter fabric has stable dimensions, high temperature resistance, large voidage, good air permeability, and wide range of uses. Due to its low price and high temperature resistance, glass fiber needle felt filter bags are the most cost-effective filter media at high temperatures. Fiberglass cloth according to the characteristics of different manufacturers of dust, often swelling, silicone oil, graphite, film, PTFE impregnation and other processing methods, the different treatment of the glass fiber cloth in the original performance and increased the permeability, easy cleaning (fast dust stripping), water and oil repellent (anti-condensation), anti-static, high dust collection rate, corrosion resistance and other properties, forming a series of products. The filter material is commonly used in roasting kiln processes in cement plants, as well as dust removal from high-temperature flue gas in iron and steel plants, chemical treatment plants, chemical plants, and other industries. The effect of dust removal is good. Glass fiber needle felt filter bags have silicone oil (yellow), silicon ink (black) Various specifications. The thickness is 0.3mm, 0.4mm, 0.5mm, 0.6mm, the filter bag diameter is φ120mm, φ130mm, φ150mm, φ160mm, φ180mm, φ230mm, φ250mm, φ300mm, the length can be made into 2000mm, 3000mm, 5000mm, 6000mm, 7400mm, 8000mm, 10000mm, can also be customized according to user requirements.
Glass fiber needle felt filter bag performance:
a, the use of temperature below 140 °C, with good anti-condensation, bending resistance and alkali resistance.
b. It has good hydrophobicity, easy to remove dust, and can meet the conditions of mechanical rapping and moisture content (about 6%–8%).
c. High strength, low resistance, good dust collection effect, dust collection efficiency of more than 99%.
d, large and stable air permeability, can significantly improve the ventilation conditions.
e. The price of glass fiber acupuncture felt bags is reasonable, and the use time is long, which can obviously reduce the use cost.
