Impermeable geotextile is one of the commonly used impermeable materials in many impermeable projects because of its good impermeability, and it is the same in landfill. But sometimes the application of impermeable geotextile in the landfill will meet the situation of degradation in advance, which is very annoying.

Once the impermeable geotextile used in the landfill is degraded before the garbage, it is easy for the unfinished garbage to pollute the surrounding environment. Therefore, it is very important to understand the reasons leading to the degradation of impermeable geotextile and to extend the service life of impermeable geotextile.

What are the factors that lead to early degradation of impermeable geotextile?

1.Properties of impermeable geotextile itself: namely, chemical properties and physical properties. For example, the weaker the crystallinity of impermeable geotextile is, the faster its degradation rate will be.

2. temperature: research has shown that the rise of temperature will lead to the degradation of antiseepage geotextile faster, and reaches a certain temperature, the degradation of antiseepage geotextile will be abnormal fast, then the temperature is where come of, in some organic oxidation decomposition can produce all kinds of material, it will send out a lot of heat, the quantity of heat is to cause the antiseepage geotextile degradation speed.

3. contact media: there are many kinds of garbage, we do not know what impermeable geotextile will be exposed to, and for metal ions, if the contact with impermeable geotextile will lead to its degradation speed up, the reason is that some metal ions and impermeable geotextile in certain components will occur antioxidant reaction.

4. there is no pad: for impermeable geotextile, if the increase in the pace of its degradation will be reduced a lot, this is because the pad can reduce some can react with impermeable geotextile contact probability.
