5.Environmentally friendly and recyclable: The raw materials are non-toxic, and it can be recycled and reused after being discarded.
Product Introduction:
Woven Polypropylene Geotextile is a type of geotextile made mainly from polypropylene. It consists of at least two sets of parallel yarns (or flat filaments). One set along the longitudinal direction of the loom is called the warp yarn, and the other set arranged transversely is called the weft yarn. It is manufactured through special machine weaving techniques.
Characteristic
Superior mechanical properties: It has quite strong tensile strength both longitudinally and transversely. Generally, the tensile strength in the longitudinal direction is greater than that in the transverse direction. It can withstand large tensile forces, tearing forces, and abrasion. It can effectively enhance the tensile strength and deformation resistance of the soil, and improve the stability of the building structure.
Good permeability: The woven structure endows the geotextile with good water permeability. Under the pressure of soil and water, it can still maintain good water permeability, allowing water to pass through. At the same time, it can effectively intercept sand and prevent its loss. It can form a drainage channel inside the soil mass, discharging the excess liquid and gas within the soil structure.
High corrosion resistance: Made from chemical fibers such as polypropylene, it has the characteristics of acid and alkali resistance, non - corrosion, non - moth - eating, and oxidation resistance. It can maintain stable performance in harsh chemical environments and has a long service life.
Strong corrosion resistance: Made from chemical fibers such as polypropylene, it has the characteristics of acid and alkali resistance, non-corrosion, non-moth-eaten, and oxidation resistance. It can maintain stable performance in harsh chemical environments and has a long service life.
Good UV resistance and weather resistance: After special treatment, it has good UV resistance. When exposed to outdoor environments for a long time, it is not easy to age or fade, and can maintain the stability of its physical properties. It is suitable for various outdoor engineering environments.
Environmental Protection and Recyclability: The polypropylene material is non-toxic and recyclable. Discarded woven polypropylene geotextiles can be recycled through appropriate recycling channels, meeting environmental protection requirements.
Easy to construct: It is relatively light in weight, which is convenient for handling and construction. During the construction process, it can be easily deployed and fixed, which can improve the construction efficiency.
