Geotextile Artificial Aging And Natural Aging
Oct 27, 2017

Geotextile artificial aging test there are many, mainly the use of climate chamber to accelerate the aging test. Modern geotextile artificial climate box with light, temperature, humidity, rainfall and other factors combined effect, in which the UV light source is the main component. Artificial climate box structure of the principle shown. According to practical experience that the light source to win the light and the sun-type carbon arc lamp simulation performance is better. Artificial climate aging faster than the natural natural aging 5-6 times, and some faster than 10 times, but its reliability as natural aging test.

Geotextile natural aging test is to put the material in a similar environment with the project for sun exposure, dipping or Chen Rong alternating test. The test results can be expressed by the aging coefficient A: () () () () () () () () () () () () () () () () () () () () () () () Structural size, physical and chemical environment and the consequences of failure and other installation - a fixed number of samples, the completion of the building after the regular or irregular sampling, determination of material performance changes and control samples to do comparative analysis. 

Or in the actual application of the material directly on the sampling test analysis, but should pay attention to take measures to ensure the safety of the project after sampling. Although this test takes a long time and can not provide information for the design and construction to be carried out immediately, it provides a valuable basis for studying the durability of geotextile materials and subsequent engineering applications.
