Concrete with PET particles demonstrated lower modulus of elasticity and splitting tensile energy with respect to standard concrete. The compressive and flexural power show an ascending pattern on the preliminary phases, nevertheless, they are likely to lower after a while. Alternatively, ultrasonic pulse checks revealed a porous structure for concrete containing pet plastic containers particles. Radiation Physics and Chemistry, Volume 162, 2019, pp. The impact of gamma rays irradiation on structural properties of polyethylene terephthalate plastic bottles terephthalate (PET) has been studied using Fourier Transform Infrared Spectroscopy (FTIR), X-rays diffraction (XRD) and UV-Visible spectrophotometry strategies. The gamma rays irradiations have been performed, using 60Co supply with mean energy of 1.25 MeV, at Nuclear Research Centre of Algiers, Algeria. The gamma absorbed dose charge was about 1.Three kGy/h as measured using the Frick dosimeter. Several PET samples with a thickness of 6 μm were irradiated at room temperature with the presence of air environment at completely different doses (0.05-5 MGy).
The surface resistivities for PET films with 1.5-2 mm thickness were rapidly decreased at the electron beam radiation of one hundred kGy (Oproiu et al., 2000). However, the modifications of the overall purposeful qualities and sensory properties on the biaxially stretched PET packaging film irradiated at a wide range of gamma doses were not properly studied. The objective of this research was to determine the consequences of γ-irradiation of 0-200 kGy on physicochemical traits, such as molecular weights, permeabilities, mechanical properties, thermal properties, colour, haze, and surface resistivity, of the biaxially stretched PET packaging film. Generally, the low doses such as 5, 10 and 30 kGy are being used in industrial sterilization strategy of foodstuffs and medical units. However the results of γ-irradiation at high dose as much as 200 kGy were adopted on this study to discover and accentuate minor differences. Commercial grade of PET film was kindly provided by Hyosung Co. Ltd.
As for the non-risky natural extractables, we additional substantiate the presence of quite a few compounds, specifically oligomers and trimers particularly, together with benzoic and terephthalic acids particularly. With respect to pharmaceutical stakes nonetheless, we claim herein that the 25 kGy sterilization dose used, triggers oligomers and extractables formation, a outcome which is promising for further threat evaluation. Nous nous intéressons aux effets des rayonnements ionisants, utilisés comme méthode de stérilisation, et notamment les électrons accélérés, sur un poly(éthylène téréphtalate) (PET) de grade médical. Les rayonnements ionisants sont connus pour induire la formation de radicaux libres dans le polymère qui, selon sa nature chimique, le sort de rayonnements et d’atmosphère d’irradiation, va ensuite soit subir une dégradation soit une réticulation de ses chaînes macromoléculaires (Charlesby, 1967 ; Dole, 1972 et Dole, 1973). Il est alors essential d’évaluer la modification du matériau de conditionnement sous stérilisation ionisante et l’objectif de ce travail est d’étudier à la fois les modifications dans le quantity du PET ainsi que d’analyser les extractibles issus de la stérilisation par électrons accélérés.
