    短纤针刺非织造土工布产品特点: 

    1、网孔不易堵塞。因不定型纤维组织形成的网状结构有应变性和运动性; 
    2、高透水性。在土方的压力下,仍能保持良好的透水性; 
    3、耐腐蚀。以丙纶或涤纶等化纤为原料,耐酸碱、不腐蚀、不虫蛀、抗氧化; 
    4、施工简便。重量轻,使用方便。

    短纤针刺非织造土工布应用范围:
    1、对具有不同物理性质的建筑材料进行隔离,使两种或多种材料间不流失、不混杂,保持材料的整体结构和功能,使构筑物荷载承受能力加强; 
    2、当水由细料土层流入粗料土层时,利用其良好的透气性和透水性,使水流通过,而有效地截留土颗粒、细砂、小石料等,以保持水土工程的稳定; 
    3、它是良好的导水材料,它可以在土体内部形成排水通道,将土体结构内多余的液体和气体排除;
    4、利用针刺土工布增强土体的抗拉强度和变形能力,增加建筑结构的稳定性,以改善土体质量; 
    5、有效地将集中应力扩散、传递或分解,防止土体受外力作用而破坏; 
    6、与其他材料(主要是沥青或塑料膜)配合,在土层中形成不透水隔层(主要用于公路重铺、修补等)。 
    7、可广泛应用于水利、水电、公路、铁路、港口、机场、运动场馆、隧洞、沿海滩涂、围垦、环保等领域,起到隔离、过滤、排水、加筋、防护、封闭作用。
