What causes the geotextile aging phenomenon
Gundam has the characteristics of the product we are all obvious, both in the highway, dams, railways and many other occasions have a very strong product features, and the performance is very outstanding, geotextile is an irreplaceable geotechnical material. Although the geotextile has unparalleled advantages, but the product is not perfect that any product has more or less problems or less, geotextile is the same, its aging problem has been with us, then in the end what causes Geotextile aging? Geotextile aging problem refers to the geotextile in the sun by the smell, temperature changes, biological erosion, chemical corrosion, moisture and other external factors, so that the geotextile strength and performance gradually weakened, loss of seepage effect. UV radiation intensity changes with the intensity of solar radiation, geotextile aging speed with the intensity of UV radiation and speed. Synthetic polymer polymer is concerned, the sun radiation is the main factor in the degradation of polymer degradation. UV radiation in the sun is the most important factor in the aging of the fabric. The ultraviolet radiation causes the polymer to produce a photooxidative decomposition reaction, especially ultraviolet light at a wavelength of 290 to 400 mPm, which has a significant decomposition effect on the polymer , Because the geotextile in the range of ultraviolet light energy is higher than the polymer chemical steamed broken the required energy, so the polymer material aging is very obvious.
