پلی پروپیلن دانلود مقاله انگلیسی بررسی خواص مکانیکی و خواص نفوذ پذیری آلیاژ پلی اتیلن ترفتالات و پلی پروپیلن مقاله انگلیسی با عنوان Mechanical Properties and Permeability of Polypropylene and Poly(ethylene terephthalate) Mixtures چکیده: The synthetic membranes currently used for soil stabilization and road construction are mainly made of polypropylene and of polyesters. They are used separately for each application. The polymer used has an effect on the wettability and the permeability of the membrane. The polypropylene membranes, for instance, have a zero wettability, whereas it is high for polyester membranes. This paper  reports on the mechanical properties and the permeability of mixtures of polypropylene (PP) and poly(ethy1ene terephthalate)  (PET). The elastic modulus of the mixture was at a minimum for a 50/50 mixture. For the other […]
