Effect of Recycling on the Rheological Properties and Foaming Behaviors of Branched Polypropylene
The effects of recycled-branched polypropylenes on their rheological properties and foamability are studied and compared with the virgin sample in this paper. The main idea is to explore the possibility of using recycled materials to make the acceptable foam products. The recycled polypropylenes showed the lower melt strength due to the disentanglement. However, the viscosity at a high shear ra...
متن کاملRheological and Thermal Properties of Icy Materials
Laboratory measurements of physical properties of planetary ices generate information for dynamical models of tectonically active icy bodies in the outer solar system. We review the methods for measuring both flow properties and thermal properties of icy planetary materials in the laboratory, and describe physical theories that are essential for intelligent extrapolation of data from laboratory...
متن کاملRheological Behaviors of Polymer Impregnated Maple Veneer
The objective of this study was to determine rheological behaviors of maple veneer plastic composite (MVPC) prepared by full cell preparation technology through the use of a rotational rheometer. The results showed that at 25 to 105 °C, the storage modulus G' and loss modulus G'' of the MVPC were apparently higher than that of the control. In the range 105 to 210 °C, the storage modulus G' of t...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولInfluence of Different Foaming Conditions on the Mechanical, Physical, and Structural Properties of Polypropylene Foam
In this article, the effects of different foam production times and temperatures on the mechanical, physical, and structural properties of polypropylene (PP) foam has been investigated. The microcellular PP foams were carried out using supercritical carbon dioxide (sc-CO2) as a physical foaming agent in a batch process. The samples were placed in a pressure vessel and were saturated ...
