Metas bag

Metas bag is a type of dust removal filter bag with stable performance, widely used in the industrial dust removal industry.

Material: The raw material of Metas bag is aromatic polyamide fiber, also known as Metas fiber, which belongs to a type of aramid fiber.

Performance characteristics:

Excellent temperature resistance: It can operate continuously at a temperature of 204 ℃, with an instantaneous temperature of up to 250 ℃, and can withstand repeated temperature fluctuations of 250 ℃.

Good dimensional stability: The thermal shrinkage rate is less than 1% at a temperature of 250 ℃, which can maintain good dimensional stability. It is confirmed that the filter bag will not be affected by shrinkage deformation in high temperature environments and will not affect the filtration effect.

Good performance (based on actual reports): The oxygen index of Metas fiber is 29, and it only begins to decompose and carbonize at 400 ℃. It does not self ignite or support combustion, and has good (based on actual reports) performance.

Outstanding mechanical performance: After treatment on the fiber surface (based on actual reports), the anti crease recovery rate is increased to over 90%, and the index (based on actual reports) is three times that of conventional polyester filter media, which can withstand more pulse cleaning impacts.

Good chemical stability: It has good tolerance to inorganic acids, and low concentrations of acids, bases, and most hydrocarbons will not affect it. Even a small amount of fluoride will not significantly corrode it. But it is prone to degradation in strong alkaline and oxidizing media, and has strong hydrolysis sensitivity. It is required that the moisture content of the flue gas be strictly controlled below 20%.

Technical parameters: Commonly used specifications of Metas bags include Φ 125 × 3200mm, Φ 127 × 3000mm, etc. The filtration efficiency of the filter bag can reach over 90%, and it can effectively capture dust particles.

Application industry: Widely used in the high-temperature filtration industry, suitable for dust collection in asphalt mixing, cement plant shaft kiln exhaust, calcium carbide plant kiln exhaust, steelmaking, casting flue gas, coking flue gas, as well as industries such as steel, non-ferrous metals, lime, dust, metallurgy, drying, crushed stone, gypsum, plastics, carbon black, coke, shipbuilding, etc.
