UV exposure of polymeric geomembranes
(Zhejiang Univ Press, 2008-01-01)
The break of polymer chemical bonds may occur due to penetration of sun short wavelengths. In sanitary landfills for instance, ultraviolet radiation affects uncovered materials and can be dangerous during the installation ...
Assessment of the interface shear strength between HDPE geomembrane and tropical soil by the direct shear test
(2018-01-01)
Liners are important impermeable constituents of sanitary landfill to contain the transport of pollutants to the unsaturated zone. The system can be made of different kind, being the compacted soil and geosynthetics widely ...
Thermoanalytical and dynamic mechanical analysis of commercial geomembranes used for fluid retention of leaching in sanitary landfills
(2018-01-01)
Studying thermal behavior is very important for monitoring the quality of polymers on an industrial scale. Commercial geomembranes are materials with low permeability that can be used for multiple purposes, such as ...
UV exposure of polymeric geomembranes
(Zhejiang Univ Press, 2014)
Evaluation of geomembrane UV degradation using melt flow index and oxidative induction time tests
(Zhejiang Univ Press, 2014)
Estudo da resistência entre interfaces de areia e geomembranas por meio de ensaios de cisalhamento direto
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2022-02-11)
Landfills have become a viable technical alternative for the disposition of solid urban residuals. To avoid soil and water contamination, geomembranes are commonly utilized on waterproof base surfaces and slopes of landfills. ...
Avaliação dos parâmetros de resistência na interface solo-geomembrana através do equipamento de cisalhamento direto
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2021-08-27)
The environmental regulations are increasingly strict, raising the problematic around the environmental contamination. The final storage of urban solid waste on landfills creates an area with a high contaminant potential ...
The Effects of Weathering Exposure on the Physical, Mechanical, and Thermal Properties of High-density Polyethylene and Poly (Vinyl Chloride)
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2013-11-01)
This paper presents results describing the physical, mechanical, and thermal properties (melt flow index - MFI and oxidative induction time - OIT) of high density polyethylene and poly (vinyl chloride) after weathering ...
