过滤材料是空气过滤过程的重要部件。过滤材料主要有玻璃纤维和化学纤维两种。玻璃纤维在高效过滤材料中有着广泛的应用,而化学纤维能够加载静电,从而获得更高的过滤效率却不会引起阻力的增加。因此带静电的化学纤维也有着非常广泛的市场。

      化纤无纺滤料俗称无纺布，学名聚酯纤维。以熔喷、热熔、纺粘、针刺、水刺等工艺经多道工序加工而成。优点:质量稳定性高,容尘量较大,耐湿性好，使用寿命长,经久耐用。缺点:阻力偏大。化纤滤料广泛使用于粗效、中效的板式、袋式过滤器;复合型无纺布也可用于中高效、甚至于亚高效过滤器。

      玻璃纤维滤料基材是中碱连续玻璃纤维斜纹组织，这种滤料柔软光滑、易清灰、能在250℃下连续使用，而且价格便宜。玻璃纤维滤布适合于滤袋中间无骨架的内滤式反吹(反吸)风或缩袋清灰的各种袋式除尘器，过滤速度一般在0.5m/ min以下。速度过高容易把滤袋吹坏，或造成透滤。在水泥工业的扬尘点推广比较多。

Filtration material is an important part of air filtration process.The filter material mainly has glass fiber and chemical fiber.Glass fiber has a wide application in high efficiency filtration materials, and the chemical fiber can load static electricity, thus obtaining higher filtration efficiency without causing the increase of resistance.So the chemical fiber with static electricity also has a very extensive market.

Chemical fiber non - spun filter commonly known as non - woven fabric, the name is polyester fiber.The process of melting jet, hot melt, spinning, acupuncture and water spines is processed by many processes.Advantages: high quality stability, high dust tolerance, good moisture resistance, long service life, durable. Disadvantages: large resistance.Chemical fiber filter is widely used in coarse and medium - effective plate type and bag filter. Compound non-woven fabric can also be used for high efficiency and even sub-high efficiency filters.

Alkali glass fiber filter material in the base material is continuous glass fiber twill weave, this kind of filter material soft smooth, Yi Qing grey, can continuous use under 250 ℃, and the price is cheap.The filter cloth of glass fiber is suitable for all kinds of bag-type dust catcher in the middle skeleton of the filter bag. The filter speed is generally lower than 0.5 m/min.Too high speed can blow out the filter bag or cause the filtration. In the cement industry the dust point promotion is more.
