Aluminum-copper green bodies were successfully prepared by a non-aqueous gelcasting system. SEM observations showed that the powder particles were completely wrapped by the polymer before degreasing, and the polymer in the metal body was completely removed after degreasing. A three-dimensional network polymer structure was obtained by the reaction mechanism. The degreasing process of the metal body was investigated by means of differential scanning calorimetry, thermogravimetry-derivative thermogravimetry and thermogravimetry-Fourier transform IR spectroscopy. The kinetic equations and parameters were gotten according to Coats-Redfern method for non-isothermal weight loss curves. The results indicate that at different heating rates the reaction order is 1, the activation energy and pre-exponential factor are ranging from 79.86 to 108.63 kJ·mol-1 and 106 to 107 min-1, resp. The activation energy reaction is sensitive to temperature and dynamics. The degreasing process is divided into two stages: a slight weight loss over a wide temperature range of 240-350°C is due to the random chain scission and the main weight loss around 380 to 425°C is attributed to depolymerization of monomers from the main chains and decrosslinking of the network polymer. The emissions of CO2, CO, NO2 and H2O are identified during the degreasing process. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Reference of 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Reference of 4074-88-8
