Composite geotechnical membrane also needs "anti-aging"

Number of hits:1032018-12-05 00:00:00

Many users are troubled by the aging of composite geotechnical membranes. Should this delay the aging of composite geotechnical membranes? The aging of the composite geochemical membrane is mainly caused by oxidation resulting in free radicals. The following is to introduce several composite geotechnical film "anti-aging" methods:
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.
