No. of bitstreams: 0 / O polietileno de ultra alto peso molecular (UHMWPE) é um plástico de engenharia que tem várias aplicações atualmente, mormente em áreas específicas da indústria e da medicina. O UHMWPE pode ser utilizado ainda em outras aplicações: defensas portuárias; guias de corrente; revestimentos de caçambas, silos e calhas; engrenagens; buchas; guias de correias e próteses cirúrgicas. Esta gama de aplicações se deve ao fato das excelentes características técnicas que este material possui, como: alta resistência a abrasão, elevada resistência ao impacto, anti-aderência, atóxico, excelente resistência química, baixo peso específico, fácil usinagem e alta resistência a fadiga. Os tipos de polietileno de ultra alto peso molecular (UHMWPE) utilizados neste trabalho foram o UTEC 3041 e UTEC 6541 da Braskem. A reciclabilidade do UHMWPE ganhou interesse, porque a utilização desta matéria-prima na última década cresceu mais de 600%, tornando-se um dos plásticos de engenharia mais utilizados para obtenção de peças usinadas depois da poliamida. Com o crescimento na utilização deste polímero na confecção de peças para maquinários, o seu desperdício tem sido muito grande, porque o resto deste material é desprezado, geralmente não sendo reaproveitado. Este trabalho tem como objetivo reciclar o UHMWPE UTEC 3041 e estudar as propriedades deste material virgem e reciclado e comparar os resultados entre si e com o UHMWPE UTEC 6541, e com estes materiais submetidos a diferentes doses de radiação. / Dissertacao (Mestrado) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN-SP

A method of measuring the electron energy losses in transmission through thin filmsStewart, John Patrick 01 May 1969 (has links)
The energy distribution in an electron beam transmitted by a thin aluminum film was studied by a retarding potential method in which the energy analysis could be made as a function of the polar angle and azimuth of scattering. The results indicated that the transmitted beam contained electrons which had lost essentially zero energy and groups of electrons which had suffered losses of approximately15 ev and 25 ev and possib1y 75 ev. In addition there appeared to be a continuous background of energy losses over the range studied (from 0 to 80 ev). The resolution of the energy analyser was limited by the separation of the data points and was not adequate to observe the dependence of the 15 ev energy loss (plasma loss) on the polar angle of scattering. This study demonstrated the feasibility of this method of energy analysis as well as the short-comings of the apparatus. Suggestions for future improvements are made.
