耐高温METAMAX (美塔斯)针刺过滤毡

耐高温METAMAX （美塔斯）针刺过滤毡

在袋式除尘领域，通常都将布袋比做袋式除尘器的心脏，布袋除尘器能处理什么样的含尘烟气，主要还取决于用来制造布袋的化学纤维本身的条件。一般的烟气温度条件下，只需要布袋能够耐150℃以下的温度，这些场合，涤纶、丙纶、晴纶、锦纶等化学纤维可以基本承受。而对于烟气温度比较高的场合，如：化工、炭黑（白炭黑）尾气、炼铁厂高炉煤气、水泥厂立窑尾气、电石厂窑炉尾气、铸造、炼钢厂烟气、沥青混凝土搅拌沥青烟气、耐火砖窑炉烟气、焦化烟气等，一是因为这些含尘烟气粉尘因受比电阻限制不适合于电收尘器收集，只能用布袋或其它方式收集；二是如需将含尘烟气温度降至150℃以下的投资较高或受现场场地的限制；三是因为含尘烟气中因为含有硫的成份，含尘烟气具有酸“露点”含尘烟气只能在酸露点以上即温度较高的状态下进行过滤分离等因素，这样就需要有一种能耐受较高温度的化学纤维用来制做滤材。

我厂选用杜邦帝人先进纤维有限公司生产的METAMAX®（美塔斯）纤维，采用国际先进标准，用引进先进设备制造生产了美塔斯耐高温针刺过滤毡。注：

1、美塔斯耐高温针刺过滤毡性能测试表见附表

2、美塔斯是美国杜邦公司生产的诺美克斯(NOMEX®)和日本帝人公司生产的抗耐克斯(CONEX®)的统称。

3、缝制美塔斯过滤袋，必须用专用的缝纫线。我厂生产制造的METAMAX 缝纫线，强度高，耐磨性好，耐温可达260℃以上。

High temperature resistant METAMAX needle punched filter felt In the field of filter bag, usually people regard the bag as the heart of filter bag, what kind of flue gas that the filter bag can deal with, it dependson the chemical fiber itself for the bag. Under the common flue gas condition, it needs that the bag can endure the 150℃below, in this occasion, polyester, polypropylene, acrylon, chinlon etc could be suitable for this. But in the high temperature occasion, such as chemical, carbon black (white carbon black) tail gas, blast furnace gas in irons melting plant, vertical kiln tail gas in cement plant, kiln furnace tail gas from calcium carbide plant, casting, flue gas of steel smelting, gypsum concrete gas, fire-resisting brick gas, coking gas etc. the powder gas is unfit for electricity dust-collecting, only using the bag or others because of the mass resistively limit, the second reason is if we cool the powder gas below the 150℃, the investment cost is higher and the space site is limited, the third is because of the sulphur content of the flue gas, and the powder gas contain the acid dewing point, it can filtrate and separate that the flue gas is under the high temperature condition, which needs the high temperature resistant chemical fiber to make the filter medium.Our factory selects METAMAX fiber from Dupont Teijin fiber co., ltd and

advanced international standard and the equipments to produce METAMAX high temperature resistant needle punched filter felt. Remark:

1.the testing figure of METAMAX high temperature resistant needle punched filter felt is the attached table.

2.METAMAX is the general designation of America Dupont's NOMEX and Japan Teijin' CONEX.

3.to sew the METAMAX filter bag, it must use the special sewing thread. METAMAX sewing thread is produced by ourselves, it has high intension, good wear resistance and high temperature resistant up to above 260℃。
