The results of the “Compound Molding of Waste Plastics, Fly Ash, and Crop Straw to Prepare New Composite Materials†researched and developed by the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences were recently awarded the first prize for technological inventions in Jilin Province.
In 2006, China’s output of crop stalks reached more than 600 million tons, but most of them were burned. At the same time, with the rapid development of China’s national economy, the production of thermal power generation and plastic products has increased substantially. In 2006, more than 7 million tons of waste plastics were used and With more than 200 million tons of fly ash, the emissions of both solid wastes increase at a rate of 10% per year, causing serious environmental pollution. How to turn these wastes into treasures and develop high-value-added products is of great significance for maintaining ecological balance and reducing pollution, and has major social and economic benefits.
Changchun Institute of Chemical Technology, Chinese Academy of Sciences, according to the needs of the country, as early as in 1995 began a variety of waste plastics, fly ash, waste slag mines, sawdust and crop straws and other blend molding to prepare new composite materials research. Under the strong support of the Science and Technology Department of Jilin Province, the Provincial Ecology Office, the Provincial Environmental Protection Agency, and the Shanghai Pudong Science and Technology Bureau, they have demonstrated their comprehensive advantages in research and development. After years of painstaking research, they invented a set of effective methods to dispose of a variety of solids. High value use. They carried out synergistic effects of various proportions, particle sizes, and auxiliary agents in the blending of various waste plastics, fly ash, waste slag, sawdust, and crop straws, processing conditions, and special processing equipment, on-line reaction processing, and other serial technologies. In-depth systematic research, the use of innovative new interface compatibilizer, the composite material can be uniformly dispersed, tightly combined, high-filling, successfully developed a series of high value-added products, such as urban water supply covers, wells, The urban afforestation uses such as municipal engineering products such as tree pools, packaging materials, pallets, wood and plastic building templates, and other construction and transportation products to realize the recycling and recycling of solid waste, turning waste into treasure, and fully complying with The principle of circular economy makes a positive contribution to building a resource-saving and environment-friendly society.
This achievement has been established in Changchun High-tech Zone since the end of 2001 with an annual production capacity of 1,500 tons of demonstration production line, so far it has been in Harbin, Heilongjiang Province, Yantai City, Shandong Province, Changchun City, Jilin Province, Shanxi Province, Taiyuan City, Jiangsu Province, Guanyun County and Jiangsu Province Nantong City and other provinces carried out general patent licensing, and established one-hundred-ton, one-thousand-ton or one-thousand-ton production plants (companies) each year, with an annual output value of more than 10 million yuan.
This achievement has been awarded key environmental protection practical technologies and national key environmental practical technologies in Jilin Province, and has been granted 5 national invention patents and 3 utility model patents. Mo Zhishen, a researcher in charge of the results, won the honorary titles of "Top Ten Patent Inventors in Jilin Province", the first "Invention and Entrepreneurship Award" of the Chinese Invention Association, and "Technology Talents in Changchun City" in 2005.
