Recently, a new type of nano-flame retardant thermal insulation material jointly developed by Suzhou Junyue New Material Technology Co., Ltd. and the Institute of Nanotechnology of Chinese Academy of Sciences and Tsinghua University has passed the scientific and technological achievements appraisal in Beijing. The material improves the efficiency of the heating network by more than 5%, the overall operating efficiency of the heating network can be as high as 97%, and the investment in the construction of the pipe network is more than 5%. The appraisal committee agreed that the technology reached the domestic leading level.
According to statistics, the annual energy loss caused by the use of thermal insulation materials in China is about 13 billion yuan.
Xue Kongkuan, dean of Beijing New Materials Architectural Design and Research Institute, said that the material is designed with a sandwich hollow insulation structure. The surface layer is made of nano-silica-coated high-purity aluminum foil, and the core layer is filled with nano-flame retardant materials, which have significant functions of heat insulation and heat preservation. The series products have been applied in the fields of industrial insulation, green buildings, automobiles, etc., and the industrialization prospects are broad.
“Traditional insulation materials mainly include rock wool, glass wool, silicate products, etc. These materials are not waterproof or susceptible to moisture. Once they are exposed to water, the insulation effect and life span are greatly reduced.†Jun Zuoqing, general manager of Junyue Technology, said that the new nanomaterials It is composed of three layers of functional materials with different characteristics. The high-purity aluminum foil has moisture-proof function, and the heat reflectivity is as high as 90%-99%; the functional layer material can effectively block any visible light and microwave energy to be transmitted outward, combined with the special technology of long-distance heat transfer network, the temperature drop of the heating pipeline per kilometer is 15 - 20 degrees Celsius is reduced to 4-6 degrees Celsius; nano material implantation and unique nanoporous network structure, strengthening thermal insulation, moisture, sound insulation, excellent resistance to oxidation and corrosion; light weight, non-toxic and non-polluting, The construction is simple and cost-effective, which will promote the development of the pipeline insulation material industry.
The material has been listed as a new energy-saving new product by Nanjing Suxia, Shandong Huaneng, Zhongji Guoneng and many other design institutes. It has passed the Australian AWTA and Swiss SGS certification, and has obtained the passport to enter the market in Australia and other countries in the world.
