聚丙烯长丝针刺土工布介绍
PP Filament NonWoven Geotextile
1. 产品介绍：
1.Product Introduction:
(1)质量轻。聚丙烯密度仅为0.91 g/cm3(聚酯为1.38 g/cm3)，因此聚丙烯土工布与聚酯土工布相比，在相同的强力下，同等质量的土工布具有更大的覆盖面积。
(2)化学稳定性好。聚丙烯具有优良的耐酸耐碱性，特别是耐碱性能优于聚酯。聚酯土工布碱性条件下或大量水分存在时易发生不可逆的水解作用，使材料性能下降甚至完全丧失，尤其不适用于与水泥、石灰、盐碱地等碱性界面直接接触的部位，而聚丙烯土工布则完全适用上述环境，且不会对环境造成污染。
(2) Good chemical stability: Polypropylene has excellent acid and alkali resistance, especially better alkali resistance than polyester. Polyester geotextile is prone to irreversible hydrolysis under alkaline conditions or in the presence of a large amount of water, which will reduce or even completely lose the performance of the material, especially not suitable for the parts in direct contact with alkaline interfaces such as cement, lime, saline alkali land, while polypropylene geotextile is fully suitable for the above environment, and will not cause environmental pollution.
(3)力学性能高。聚丙烯纺粘针刺土工布是由连续的聚丙烯长丝固结而成，布面拉伸断裂形式主要为纤维的断裂，而短纤土工布主要为纤维之间的抽拔，因此，聚丙烯纺粘针刺土工布的强力、延伸率等力学性能都要优于短纤土工布。
(3) High mechanical properties:Polypropylene spunbonded needle punched geotextile is formed by the consolidation of continuous polypropylene filaments. The main form of tensile fracture on the fabric surface is fiber fracture, while short fiber geotextile mainly involves fiber extraction between fibers. Therefore, the strength, elongation, and other mechanical properties of polypropylene spunbonded needle punched geotextile are superior to short fiber geotextile.
(4)排水性能好。聚丙烯具有极好的疏水性，但有良好的导水作用，在排水工程中应用优于聚酯。
(4) Good drainage performance: Polypropylene has excellent hydrophobicity, but it has good water conductivity and is better than polyester in drainage engineering applications.
(5)过滤效果好。我公司生产的聚丙烯土工布，可以实现不同旦数的聚丙烯非织造布的复合，形成双层过滤，过滤效果更好。
(5) Good filtering effect: The polypropylene geotextile produced by our company can achieve the composite of polypropylene non-woven fabrics with different denier numbers, forming a double-layer filtration and achieving better filtration effect.
(6)施工方便。聚丙烯纺粘针刺土工布针刺密度低，布面柔软不僵硬，更加贴合使用面，铺设安装更加方便。
(6) Convenient construction: Polypropylene spunbonded needle punched geotextile has a low needle density, a soft and non rigid surface, and is more suitable for use, making laying and installation more convenient.

3.主要用途：
3. Application:
(1)防渗透：长丝土工布可以作为一种优秀的防渗材料，用于各种水利、水电、交通、城市建设等工程中的防渗措施。例如，可以用于大坝、隧道、水库、垃圾填埋场、防渗墙等工程中，防止水的渗透和泄漏。
(1) Anti permeability: Long filament geotextile can be used as an excellent anti-seepage material for various anti-seepage measures in water conservancy, hydropower, transportation, urban construction, and other projects. For example, it can be used in projects such as dams, tunnels, reservoirs, landfills, and anti-seepage walls to prevent water infiltration and leakage.
(2)加固增强：长丝土工布可以作为加固材料，用于各种地基加固和土体加强工程中。例如，在路基、铁路、机场、码头等工程中，可以用长丝土工布加强土体，提高土体的承载力和稳定性。
(2) Reinforcement and reinforcement: Long filament geotextile can be used as a reinforcement material for various foundation reinforcement and soil reinforcement projects. For example, in projects such as roadbeds, railways, airports, and docks, long filament geotextiles can be used to strengthen the soil and improve its bearing capacity and stability.
(3)防护隔离：长丝土工布可以作为一种防护隔离材料，用于各种防护和隔离工程中。例如，在海岸防护、河岸防护、土坡防护等工程中，可以用长丝土工布作为一种隔离材料，防止土体的冲刷和侵蚀。
(3) Protective isolation: Long filament geotextile can be used as a protective isolation material for various protective and isolation projects. For example, in projects such as coastal protection, riverbank protection, and soil slope protection, filament geotextile can be used as an isolation material to prevent soil erosion and erosion.
(4)环境保护：长丝土工布可以用于环境保护工程中，例如垃圾填埋场、污水处理厂等工程中，可以用长丝土工布作为一种覆盖材料，防止污染物的扩散和渗漏。
（4）(4) Environmental protection: Long filament geotextile can be used in environmental protection projects, such as landfills, sewage treatment plants, etc. It can be used as a covering material to prevent the diffusion and leakage of pollutants.
