DOWNLOAD EBOOKPolymerization is a process which is chemically combined of small molecules to produce a very large chain or network molecule, called a polymer. By the way, the small molecules may be alike, or they may represent of two, three, or more different compounds with different molecular weight. This research proposes is to study the effect of temperature on polymerization kinetics of methyl methacrylate (MMA). Thermal study on methyl methacrylate is important to explain the heat and mass transfer phenomena during polymerization reaction. The objective of this study is to determine the temperature effect on polymerization kinetics of methyl methacrylate (MMA) with initiator. Mass of methyl methacrylate as monomer will be fixed at 3miligrams and also mass of initiator which is azo-bisisobutyronitrile (AIBN) will constant at 2miligrams. These two components will put on the pan by micropipette. The pan will tightly seal and be put into the differential scanning calorimetry (DSC). Each of samples will run until five hours in different temperatures (35°C, 45°C, 55°C, 65°C and 75° C). Then the polymerization kinetics and heat released are analyzed using this differential scanning calorimetry (DSC). From the (DSC) the curves or data of temperature, time and heat released are obtained. From these result obtained, increasing the temperature will decrease the time of reaction taken. High temperature will increase the amount of heat low or heat release. As increase the temperature, the rate of reaction increase due to the increasing of collision frequency and produce more energy to start the reaction.

DOWNLOAD EBOOKThe Effect of Temperature and Other Factors on the Properties of Plastics and Elastomers, Fourth Edition provides data on the wide spectrum of plastics and TPEs with special reference to thermal stability. The mechanical, physical and electrical properties of plastics and elastomers are described as a function of temperature and humidity to help with the design of lighter more cost-effective plastic parts to replace metal ones. In this new edition, expertly edited data makes it easy for readers to learn about the properties of plastic materials without having to search the general literature or depend on suppliers. Additional types of plastics are examined, and the latest data on material characteristics are provided. Complex details such as how the thermal prehistory can effect final mechanical properties, and how temperature scans reveal dynamic mechanical behavior are also examined to build a deeper understanding of the materials. Fully updated edition features full coverage of the new data, new plastics and applications that have emerged in recent years Features reorganization of plastics data by manufacturer, facilitating quick reference

DOWNLOAD EBOOKIn Infrared Thermography, the authors discuss the sources of uncertainty, including how to quantify these sources, associated with the use of thermal imagers. This book explains the common misunderstandings in the interpretation of temperature measurements, and provides a metrological evaluation of commercially available infrared cameras. It suggests how to best estimate the accuracy of thermal imaging instruments, whilst considering the level of accuracy attributed to measurements from these thermal imagers. Key features: Begins with an introduction to uncertainties and radiance terms before moving onto the issues surrounding thermal imaging. Deals with the basic issues of thermal imager measurements such as the law of heat exchange by radiation and emissivity. Describes a typical processing algorithm of the measurement path for an example infrared camera. Discusses measurement error analysis of a thermal imaging system. Considers the results of simulation research of thermography uncertainty. Includes an accompanying website which hosts MATLAB® code. Infrared Thermography is primarily aimed at quantitative thermographers, and manufacturers, vendors and users of thermal imagers. This book is also of interest to senior undergraduate and postgraduate students across a range of disciplines such as electrical, mechanical and civil engineering, computer science, and biomedicine.
