玻璃纤维针刺毡
玻璃纤维针刺毡是一种结构合理、性能较好的过滤材料，以玻璃纤维为原料，用刺针对梳理后的短切玻纤毡进行针刺，用机械方法使毡层玻纤之间、毡层玻纤与增强玻纤基布之间纤维相互缠结，纤网得以加固而制成的毡状非织造布过滤材料。
它不仅具有玻纤织物耐高温、耐腐蚀、尺寸稳定、伸长收缩率极小、强度高的优点，而且毡层纤维呈单纤维，三维微孔结构，孔隙率高，对气体过滤阻力小，是一种较高速、高效的高温过滤材料。与其它的耐高温化纤毡相比，其具有价格低、耐温更高等特殊优点，但其运行阻力高于一般化纤高温滤材
1、断热性佳:根据物理原理，气体的热传导率小、**的断热材质内部均有很多空气穴。而玻璃纤维针刺棉具有无数细小气体，且纤维呈现不规则排列，为极佳隔热材料，热传导系数0.2~0.040kcal/mhr。c之间;
2、不会燃烧:玻璃纤维的主要成分为硅化物(占50%以上)，具有不燃性、无变形、无脆化，耐高温达700℃;
3、吸音率良:当音波侵入玻璃纤维棉时，其能量会因与纤维及大小不同气穴的摩擦，而被大量吸入。一般而言，吸音率皆高达90%以上，是防止杂音干扰的良才;
4、绝缘性高:玻璃纤维能耐高温，机械性良好，且化学安定性高，是**的绝缘材料;
5、耐腐蚀性高:玻璃纤维不怕强酸、强碱，长时间不会减低其功能特性;
6、复原性好:玻璃纤维内含无数固定气穴，复原性**。不怕任何冲击震动，抗拉强度均1.0kg以上。
7、吸湿率低:吸湿率通常接近于零。
8、重量轻而软:与其他隔热材比较，玻璃纤维针刺毡的质量**轻、**柔，若安装在机械上，可减轻其重量与震动的负荷。
9、施工简易:尺寸可依客户来裁切。
玻璃纤维针刺毡可用于汽车工业中的隔音、吸音、减震、阻燃等，主要用于工业中的过滤领域;高温烟气过滤;玻璃纤维针刺毡广泛应用于炭黑、钢铁、有色金属、化工、焚烧等行业的烟气净化和粉尘回收各种袋式除尘器。
Glass fiber needled Mat
Glass fiber needled Mat is a kind of filter material with a reasonable structure and good performance. It is made of glass fiber as raw material. After carding, the short-cut glass fiber mat is needled with a needle. By mechanical means, the fibers between the glass fibers in the mat layer and between the glass fibers in the mat layer and the reinforcing glass fiber base fabric are entangled with each other, and the fiber web is reinforced to form a felt-like nonwoven fabric filter material.
It not only possesses the advantages of glass fiber fabrics such as high-temperature resistance, corrosion resistance, dimensional stability, extremely small elongation and shrinkage rate, and high strength, but also the felt layer fibers are single-fiber, with a three-dimensional micro-porous structure, high porosity, and low resistance to gas filtration. It is a relatively high-speed and efficient high-temperature filtration material. Compared with other high-temperature resistant chemical fiber felts, it has special advantages such as lower price and higher temperature resistance, but its operating resistance is higher than that of general chemical fiber high-temperature filter materials.
