聚丙烯長絲針刺土工布介紹

PP Filament NonWoven Geotextile

1. 產品介紹：

1.Product Introduction:

(1)質量輕。聚丙烯密度僅為0.91 g/cm3(聚酯為1.38 g/cm3)，因此聚丙烯土工布與聚酯土工布相比，在相同的強力下，同等質量的土工布具有更大的覆蓋面積。

 (1) Lightweight: The density of polypropylene is only 0.91 g/cm3 (polyester is 1.38 g/cm3), so polypropylene geotextile has a larger coverage area compared to polyester geotextile under the same strength.

(2)化學穩定性好。聚丙烯具有優良的耐酸耐堿性，特別是耐堿性能優于聚酯。聚酯土工布堿性條件下或大量水分存在時易發生不可逆的水解作用，使材料性能下降甚至完全喪失，尤其不適用于與水泥、石灰、鹽堿地等堿性界面直接接觸的部位，而聚丙烯土工布則完全適用上述環境，且不會對環境造成污染。

(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)力學性能高。聚丙烯紡粘針刺土工布是由連續的聚丙烯長絲固結而成，布面拉伸斷裂形式主要為纖維的斷裂，而短纖土工布主要為纖維之間的抽拔，因此，聚丙烯紡粘針刺土工布的強力、延伸率等力學性能都要優于短纖土工布。

(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。聚丙烯具有極好的疏水性，但有良好的導水作用，在排水工程中應用優于聚酯。

(4) Good drainage performance: Polypropylene has excellent hydrophobicity, but it has good water conductivity and is better than polyester in drainage engineering applications.

(5)過濾效果好。我公司生產的聚丙烯土工布，可以實現不同旦數的聚丙烯非織造布的復合，形成雙層過濾，過濾效果更好。

(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。聚丙烯紡粘針刺土工布針刺密度低，布面柔軟不僵硬，更加貼合使用面，鋪設安裝更加方便。

(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)防滲透：長絲土工布可以作為一種優秀的防滲材料，用于各種水利、水電、交通、城市建設等工程中的防滲措施。例如，可以用于大壩、隧道、水庫、垃圾填埋場、防滲墻等工程中，防止水的滲透和泄漏。

(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)加固增強：長絲土工布可以作為加固材料，用于各種地基加固和土體加強工程中。例如，在路基、鐵路、機場、碼頭等工程中，可以用長絲土工布加強土體，提高土體的承載力和穩定性。

(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)防護隔離：長絲土工布可以作為一種防護隔離材料，用于各種防護和隔離工程中。例如，在海岸防護、河岸防護、土坡防護等工程中，可以用長絲土工布作為一種隔離材料，防止土體的沖刷和侵蝕。

(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)環境保護：長絲土工布可以用于環境保護工程中，例如垃圾填埋場、污水處理廠等工程中，可以用長絲土工布作為一種覆蓋材料，防止污染物的擴散和滲漏。

（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.
