Any item has a certain period of use, but it is only a long-term problem. For geotextiles, its use time is closely related to the surrounding environment. Temperature changes, biological erosion, chemical corrosion and other factors may affect the geotextile fabric. The length of use, but also because of the existence of these factors, we need to pay extra attention when using geotextiles, so as to extend the service life of geotextiles.

The aging of geotextiles is fast. In the end, those factors are driving this process. Guangdong geotextile manufacturers solve this mystery for you. Geotextile aging means that geotextiles are affected by sunlight, radiation, temperature changes, bio-erodibility, chemical corrosion, moisture, and other external factors, so that the strength and performance of fabric geotextiles gradually weakened, and they lose their functions. This process is the aging of geotextiles. The factors that affect the aging of geotextiles are numerous and complex, often due to the simultaneous effects of several factors.

In terms of artificially synthesized macromolecule polymers, sunlight radiation is a major factor in polymer degradation and degradation. Ultraviolet radiation in sunlight is the main cause of fabric aging. Due to ultraviolet radiation, high-molecular polymers produce photooxidative decomposition reactions, especially ultraviolet light with a wavelength of 290 to 400 mPm (soap micron), to high-molecular polymers. There is a significant decomposition effect, because the energy of the ultraviolet light in this range of geotextiles is higher than the energy required for the breakage of polymer chemistry crucibles, so the aging of polymer materials is very obvious. Among them, the polypropylene material is less than the tertiary carbon atom in the molecular structure, and the carbon and hydrogen bond energy of the tertiary carbon atom is small, and thus unstable. Therefore, polypropylene is more sensitive to photooxidative degradation reaction, and its aging is the most sensitive when its wavelength is 300-310mF ((soap micrometer). The intensity of ultraviolet radiation changes with the intensity of solar radiation, and the aging rate of geotextile is also related to ultraviolet The level and intensity of radiation intensity is also related to the type, structure, color, temperature, humidity, admixture, etc. of geotextiles.The non-woven fabrics, especially thick fabrics, have the dual functions of percolation and drainage, and can be used in soil. The water is transported out of the building along the plane of the fabric to reduce the osmotic pressure and ensure the stability of the building.This is the role of the geotechnical fabric in the horizontal infiltration or water conduction. It is only applicable to laminar flow conditions.When the hydraulic gradient is equal to 1;1, the permeation flow rate is the horizontal permeability coefficient along the fabric plane, the horizontal permeability coefficient is similar to the hydraulic conductivity scoop fabric type, structure, pore size, flow state, water flow The direction, the fabric is affected by many factors such as the size of the normal pressure! In the practical application of the project, there will always be a certain load on the upper part of the fabric, so that The internal structure of the geotextile changes by c. The fabric is composed of multiple TL-gap fibers. As the pressure increases, the fabric 7L slackens accordingly.

The above factors are responsible for the accelerated aging of geotextiles. Since we know the problems are there, then the next step is how to solve the problems. According to the above analysis, when customers choose geotextiles, they should choose those that are not suitable for sunlight. The reaction, as well as the anti-corrosion performance must be better, in the daily use should also pay attention to maintenance, so that the service life of geotextile will be greatly increased.
