产品介绍：
高强聚丙烯长丝纺粘针刺土工布
High strength PP filament spunbond needle punched nonwoven geotextile
（1）聚丙烯密度较小，仅为0.91g/m3（涤纶为1.38g／m3），因此聚丙烯土工布与聚酯士工布相比，在相同的强力下，具有更大的覆盖面积。
（2)聚丙烯的特殊结构使其具有优良的耐酸耐碱性能，特别是耐碱性能优于聚酯，在土质酸碱性较强的地下进行防护、加强、防水、防等工程中使用时其效果好于聚酯。
（3丙烯纤维表面摩擦系数较小，纤维之间的摩擦力小，而且耐磨性好，抗震动摩擦性能远好于涤纶。
(4)丙烯具有良好的疏水性，不吸水，在给排水工程中应用优于聚酯。
（5丙烯纤维针刺士工布比相同克重的聚酯针刺土工布强力高，而且纵横向强力相等。
应用范围
聚丙烯纺粘针刺土工布具有优越的物理性能和良好的化学稳定性，因此，它适用于任何岩士工程，特别是有酸碱性的环境。如：公路、铁路（高铁）、机场、海港、垃圾填埋场、尾矿坝、粉煤灰填埋场、灰坝池、人造湿地、江河湖海治理、水库、水梁、填海造地、污水治理等工程。
(1) The polypropylene has a low density of only 0.91 g/m3 (polyester is 1.38 g/m3), so the polypropylene geotextile has a larger coverage area under the same strength as the polyester fabric.
(2) The special structure of polypropylene makes it have excellent acid and alkali resistance, especially the alkali resistance is better than polyester. It is effective when used in the protection, strengthening, waterproofing and corrosion engineering of underground soil with strong acidity and alkalinity than polyester.
(3) The surface friction coefficient of polypropylene fiber is small, the friction between fibers is small, and the wear resistance is good, and the vibration friction performance is much better than polyester.
(4) Polypropylene has good hydrophobicity, no water absorption, and is superior to polyester in water supply and drainage engineering.
(5) Acrylic fiber needle-punched fabric is stronger than the same weight of polyester needle-punched geotextile, and the vertical and horizontal strength is equal.
Application：
In virtue of the superior physical properties and good chemical stability of PP geotextile N can be applied to any geotechnical engineering environment, especially the environment with acid and alkaline, such as highway railway(HSR) airport, seaport, landfill, tailings dam, fly ash landflll, ash dam pool, artificial wetlands, rivers and lakes governance,reservoirs.canals. land reclamation, sewage treatment works etc.
