Composite geotechnical membrane also needs "anti-aging"

1. Reduce the sensitivity of composite geotechnical membrane materials to light and heat, prevent the formation of stimulated parts and free radicals in polymers;
2. Decompose the hydrogen peroxide compounds that have been produced;
3. Capture the free radicals that have been generated so that they do not cause chain reactions or terminate the reaction;
4. Passification of heavy metals in polymers;
These antiaging agents are generally not used in a single way, but are used in combination with different materials. This has become the most basic method for preventing aging of composite geotechnical membranes. The corresponding anti-aging agents include ultraviolet shielding agents, thermal stabilizers, ultraviolet absorbers, energy shredders, free radical chain reaction inhibitors, free radical scavengers, peroxides, metal passivators, and mildew inhibitors.
