The aim of this study was to investigate the electrical resistance of polycarbonate film and polyester film materials in new energy materials during electrothermal aging in transformer oil. Insulating paper was used as a comparative material to compare the breakdown voltage and initial voltage of insulating paper, polycarbonate film, and polyester film in electrothermal aging at 90 °C, 110 °C, and 130 °C. The best performance in the test was achieved by polycarbonate film, followed by polyester film, while the worst performance was that of insulating paper. Polycarbonate film can be used as an insulating material in transformers, and it has great application value and commercial prospects.

As an old industrial base of the northeast, energy material application is Changchun’s necessary choice for the low-carbon economy development. Analysis shows that new energy materials should be applied to electric power industry. Replacing the thermal power generation mainly using coal by new energy materials power generation, energy consumption in thermal power and carbon emissions will be reduced. Second, with new energy materials applying to nonmetal mineral products and other industries, the consumption proportion of coal and fossil oil in the industrial process will be reduced.

AbstractInsulating paper is a traditional insulation material used for transformer insulation. Transformer development is not only limited to small sizes and large capacities, but also limited to insulation life as insulating paper cannot withstand high temperatures. Therefore, recent studies have focused on improving the performance of insulation paper and discovering better insulation materials. In this study, two types of polymeric materials, polycarbonate (PC) and polyester film (PET), were chosen for comparative analysis. In order to test whether these two materials could be used in oil-immersed transformers, the PC and PET were placed in transformer oil for thermal aging at 110°C and 130°C, respectively. The thermal cracking processes and fragmentation mechanisms of the PC, PET, and insulation paper were analyzed using thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), and atomic force microscopy (AFM), as well as their degrees of polymerization and surface morphologies. According to the test results, the initial thermal decomposition temperature of PC and PET are higher than insulation paper and exhibited a better thermal resistance. PC and PET have the potential to substitute insulation paper for large capacity power transformer.

Biogas Productivity

The object of this study is to open the new ways of exploitation and utilization of traditional Chinese medicine residue (TCMR) as new energy material to produce biogas through indoor simulation tests. The experiment is carried out to study the effect of physical pretreatment by crusher on the biogas productivity of TCMR under medium temperature condition (35°C). TCMR is used as signal fermentation material without foreign elements which is 5% and cow dung is 10% for inoculum. The batch anaerobic digestion technology and the drainage collection biogas method are used. The results show that there is similar total biogas yield between the smashed TCMR and the unsmashed TCMR, of which the former is 9.35 L and the later is 9.28 L during 51 days fermentation. The biogas yield of smashed TCMR is higher than that of TCMR during fermentation starting period, and lower at the later stage. The results suggest that TCMR could be regarded as biogas fermentation material, and should not be smashed in order to economize the production cost.

Teaching Purpose

<p>With the rapid development of science and technology, the material discipline also developed rapidly, and gradually developed a lot of new materials. With the emergence of new materials, there are many specialties such as nanometer materials and technology, functional materials, new energy materials and devices. The material chemistry major is a kind of material and chemistry cross traditional major. The teaching purpose of material chemistry major is to improve students' knowledge and skills in material chemistry, so that they can carry out scientific research, teaching, development and other management work in engineering, material science and other related industries, and become an innovative talent in the field of material science. At present, in the environment of rapid development of large materials, the most prominent problem of material chemistry major is how to highlight the specialty characteristics as much as possible in this environment, so as to realize the construction and development of specialty characteristics.</p>
