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 peroxy radicals and free radicals and other substances react chemically or physically migration, extraction, washing and evaporation loss, etc., usually by oxidation induction time (OIT) test was measured, the experiment there are two types, i.e. OIT OIT test standard and high-pressure test. Phase II for the induction of oxidative degradation of Shandong Hongxiang Geomembrane, Geomembrane mechanical properties of this period remains unchanged, but will find significant changes in molecular composition, general Fourier transform infrared spectrum 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. As we all know, artificial lakes, streams, ponds and other water bodies as a magnificent colorful landscape adds a lot of facial beauty, in recent years, with good function of impermeable geomembrane is increasingly used in the construction of water bodies grassroots anti latest seepage geomembrane, to meet the different venues environment, natural conditions and river modeling waterscape building requirements. China Garden shelterbelt June 30 news: As we all know, artificial lakes, streams, ponds and other water bodies as a magnificent colorful landscape adds a lot of facial beauty, in recent years, with good impermeable geomembrane functions are increasingly used at grassroots water bodies to meet the different venues environment, natural conditions and river modeling waterscape building requirements. After Geomembrane business building in integrated supply Urumqi County landscaping project, the construction side in the full study Urumqi special geographical environment and relatively harsh natural conditions Geomembrane manufacturers, decided to adopt geomembrane construction method Water and water features constructed. According to the person in charge of overseeing the project description, geomembrane construction method can not only make full use of resources, cost savings, but also effectively prevent the venue too valuable water infiltration and erosion. According to the Xinjiang drought seasons climate characteristics, local landscaping projects generally elastomer modified bitumen membrane (SBS membrane) as a water impermeable material. However, the use of such water technology, construction costs are relatively high for grassroots conditions require high. First, you must pouring concrete cushion and cushion surface must be flat; secondly, the construction of the moisture content can not be too large, otherwise it will affect the quality of the project. "After repeated market research and material testing, we agreed that the overall performance of the geomembrane even better than SBS membrane. Constructors reinforce river, after Waterscape grassroots, paved pure loess, ramming to 97% after the density, laying a thickness of 4 mm geomembrane, after meticulous stone concrete upper geomembrane protective layer, which not only improves the stability of the base structure, to ensure project quality, and reduce the cost of the project, this alone saves for projects over 10 million, praise the owners and supervision.
