Geomembrane additives which are composed ::? Geomembrane for polymers, from 96% to 97.5% polyvinyl resin, 2% to 3% black and 0.5% to 1% of the additives. Depending on the environmental conditions and mechanism of action, the degradation of type Geomembrane is divided into oxidative degradation, extraction degradation, UV and thermal degradation, oxidative degradation is at the bottom of the landfill impermeable membrane impermeable geomembrane main degradation type . Oxidation process is essentially a process of radical chain reactions can be divided into three stages, each stage of a process on behalf of an antioxidant (stabilizer) consumed during this period Geomembrane mechanical properties do not change, the major antioxidant and oxygen , alkyl radicals and peroxide radicals and other substances react chemically impermeable geomembrane, or physical migration, extraction, washing and evaporation losses, etc., usually by oxidation induction time (OIT) test determined that the experiment has two types, namely standard OIT OIT test and pressure test. Phase II for induction of oxidative degradation, mechanical properties during this period Geomembrane remains unchanged, while the molecules will find significant changes in the quality of Geomembrane, general use of Fourier transform infrared spectroscopy analyzer (FTIR) analysis. Phase III is the oxidative degradation of the early stage of this physical effect occurs mainly in the molecular cross-linking the main molecular weight increases, the degree of crystallinity increased, no significant changes in the nature of the project; late into chemistry, to the role of the main chain scission, molecular weight reduced engineering properties decreased (eg fracture stress and strain, tensile modulus, etc.), until the final instability, stage three ends. Generally believed that when the engineering properties of Geomembrane (such as stress cracking, stress crack and crack strain) down to a specific value (50% of the engineering properties of the original value or to a specified value) when the following is considered its loss stable. Melt flow index MI constant load tests and notch tensile test NCTL is effective analysis of two experiments that stage, the former for molecular testing Geomembrane, the latter mainly to measure stress cracking characteristics. To study investigated the geomembrane, especially the larger aperture woven fabric for protection engineering, natural waves, currents, tides role in the anti-scouring brush case, geomembrane select projects to be applied several non-woven fabric (non-woven) and Nonwovens (Table 5 -] 2 Pat, E6 two kinds of woven cloth), respectively, in the Liaohe River revetment project site, surrounded by Gulf Temple Xingcheng long seawall and Dawa River embankment scouring brush Dipo conducted a field test. Test methods; the soil is protected weighed into the one. oM: 1.0m x o. 1M wooden box inside, according to a certain density compaction impermeable geomembrane manufacturers, geomembrane cover above, and fixed on the wooden frame, sub-capping layer (concrete slab, etc.) geomembrane and geotextile layer uncovered two situation, and then be subjected to the shore or on the wooden box set Dipo currents, waves scouring brush, after "a given time, will remove said soil heavy wooden box by the front and rear Test water content, particle analysis, conducted before and after the protected soil erosion dry soil weight and analyze the changes and other particles, can be seen from Table 5-10, soil erosion after heavy basically scour more than before, not decreased, but increased. From the perspective of the soil particles, after scouring powder teach grain increased wholesale Geomembrane, analysis of the reasons is the geomembrane 7L soil particle diameter greater than when the shock waves of water or cloth, it is possible to Ken river water, sediment punch people box, River sediment concentration due to geomembrane test for 3.o-6.okdm3, the median size o. Tsukuda .o.026M. This shows that in the larger river sediment concentration, the larger the aperture is not geomembrane cause scouring brush protected territories, you can use something todD oM design specifications.
