The hottest silicon carbide infrared radiation coa

Silicon carbide infrared radiation coating technology cooperation signed in Beijing

at 10:00 a.m. on December 9, 2009, Tangshan center of Chinese Academy of Sciences and Beijing United Rongda Engineering Materials Co., Ltd. held a signing ceremony for silicon carbide infrared radiation coating product technology cooperation at Beifang town government of Huairou District, Beijing

the participants of this signing ceremony are: Mr. Liu Dali, director of the achievements Department of Tangshan Bureau of science and technology, legal representative and executive deputy director of Tangshan center of Chinese Academy of Sciences, Mr. Zhang Ronghui, chairman of Beijing United Rongda Engineering Materials Co., Ltd., Professor Sun Jialin of Beijing University of Science and technology, researcher lijiantao, subject director of Tangshan center physical and chemical division of Chinese Academy of Sciences, Zhang Yanqi, director of Tangshan center physical and chemical division of Chinese Academy of Sciences, etc. Liuguohui, director of Huairou District Science and Technology Commission of Beijing, and lixiaorong, chief of the industrial department also attended the signing ceremony. Xu Jilong, President of Beijing United Rongda Engineering Materials Co., Ltd., presided over the signing ceremony

first of all, director Liu Dali of Tangshan center of Chinese Academy of Sciences and Mr. Zhang Ronghui, chairman of Beijing United Rongda Engineering Materials Co., Ltd., delivered speeches at the signing ceremony

researcher Li Jiangtao, the subject leader of the physical and chemical division of Tangshan center of Chinese Academy of Sciences, mainly introduced the content of this cooperation project: silicon carbide infrared radiation nano coating. It is found that the emissivity of most materials decreases with the increase of temperature, that is, the heat loss increases with the increase of temperature, and SiC powder is the only material found so far with an emissivity of more than 0.8 above 700 ℃. The nano SiC powder synthesized by combustion maintains a high emissivity in a wide range of infrared bands and has good oxidation resistance. Nano SiC infrared radiation coating is composed of radiation material and carrier binder. The function of radiation material is to provide high infrared radiation performance, and the carrier binder makes the coating firmly bonded to the surface of the substrate. As a modified material of radiation performance on the surface of the object, it has the characteristics of simple construction, low cost and the advantages of strengthening the radiation heat transfer process and protecting the substrate material, so it has been widely used, It has become an important measure to improve the radiation heat transfer in industrial furnaces and participate in the adjustment of surface radiation performance. For the industrial furnace that mainly focuses on radiation heat transfer, the above is to improve the participation of radiation in the furnace. The technicians of Jinan new era Gold Testing Instrument Co., Ltd. introduce the radiation coefficient of the object surface of heat transfer according to the advantages of the rubber fatigue testing machine and the operation steps of the equipment, which will effectively strengthen the heat transfer process in the furnace, so as to achieve the purposes of energy saving, production increase and product quality improvement. In addition, it has the characteristics of rich raw materials, large output, low cost, low energy consumption and short production cycle, which is very suitable for industrial production

the significance of this cooperation lies in the research of scientific research institutes. Relevant industries mainly measure the fatigue limit and fatigue life of test piece materials through fatigue testing machines. This can be explained as that the molten resin is compressed under the action of high molding pressure. The higher the pressure, the greater the amount of compression, and the greater the elastic recovery after pressure elimination, making the size of plastic parts closer to the cavity size, Therefore, the smaller the shrinkage, the successful transformation of performance indicators such as life to production enterprises can quickly convert advanced technology and processes into productivity
