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, 2014)
Degradação de geomembranas de polietileno de alta densidade (HDPE) após exposição à intempérie e lixívia
(2010)
This paper presents some results of MFI and OIT tests performed on HDPE geomembranes of 0,8 and 2,5 mm that were exposed to weathering effects and leachate after 30 months (2,5 years). The aim of this work is the evaluation ...
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 ...
UV exposure of polymeric geomembranes
(Zhejiang Univ Press, 2014)
Evaluation of stress cracking on geomembranes after accelerated tests
(2014)
This paper presents results of stress cracking tests performed in high density polyethylene (HDPE) geomembranes (GM). Stress cracking tests were performed in accordance to ASTM D5397: Notched Constant Tensile Load Test ...
Evaluation of geomembrane UV degradation using melt flow index and oxidative induction time tests
(Zhejiang Univ Press, 2014)
Efeito da vinhaça na membrana impermeabilizante usada nos tanques de armazenamento
(2013)
This work evaluated the effect of vinasse (residue from sugar cane) in high density polyethylene (HDPE) geomembranes having in mind that it is deposited at temperatures of 80-90˚C on the geomembrane in storage tanks. The ...
