Filament geotextile is an environment-friendly building material without chemical additives and heat treatment. It has good mechanical properties, good water permeability, corrosion resistance, aging resistance, adaptability to uneven base course, resistance to external construction forces, low creep, and can still maintain its original function under long-term load.
In many projects, the application of filament geotextile is very extensive, but the filament geotextile has a certain service life, and its service life is also a concern of many users at present. The reduction of the service life of geotextile is mainly due to aging, product material, construction quality and other factors.
1、 What factors are related to the service life of filament geotextile
In order to prolong the service life of geotextile, let’s talk about the causes of geotextile aging. There are many reasons, mainly including internal and external causes. The internal causes mainly refer to the performance of geotextile itself, the performance of fibers, the quality of additives, etc. The external causes are mainly environmental factors, including light, temperature, acid-base environment, etc. However, the aging of geotextile is not a factor, but the result of a combination of many factors, External factors have greater influence on the aging of geotextiles.
2、 How to prolong the service life of filament geotextile
1. The selection of geotextile raw materials is very important. Many small geotextile factories use less domestic raw materials, so the quality of the products produced will not be good. Therefore, it is also very important to select a competent geotextile manufacturer.
2. The construction process shall be controlled in strict accordance with the relevant construction specifications of geotextile, otherwise the construction quality and service life of geotextile cannot be guaranteed,
3. Pay attention to whether the surface of the product is damaged during use, so as to ensure that the quality of the product used meets the standard; The normal service life of general geotextile products is that after 2-3 months of sunshine, the strength will be completely lost. However, if anti-aging agent is added to the geotextile, after 4 years of direct sunlight, the strength loss is only 25%. The geotextile can maintain strong tensile properties with plastic fibers in dry and wet environments.
4. Add sunscreen and anti-aging agent to adapt to complex construction environment.
3、 Characteristics of filament geotextile
1. High strength. Due to the use of plastic fiber, it can maintain sufficient strength and elongation under wet and dry conditions.
2. Corrosion resistance, which can withstand corrosion for a long time in soil and water with different pH values.
3. Good water permeability. There are gaps between fibers, so the water permeability is good.
4. Good antibacterial performance, no damage to microorganisms and insects.
5. The construction is convenient. Because the materials are light and soft, the transportation, laying and construction are convenient.
6. Complete specifications: the width can reach 9m. At present, it is a domestic wide product, with a unit area weight of 100-800g/m2
