Recently, the national key research and development plan project - chemical and structure-driven controllable performance agricultural film material development and industrialization demonstration project held a promotion meeting in Shanghai.
The promotion will be organized by the project-leading unit Sinopec Shanghai Petrochemical Research Institute, hosted by the project participant Hongrui Bio, Tsinghua University, University of Science and Technology of China, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Baishan Xifeng Plastic Industry Co., Ltd., Zhejiang Hai Zheng Biomaterials Co., Ltd. participated in the project. The project is a key project of 'Key Basic Materials Technology Improvement and Industrialization', which was established by the National Key Research and Development Program in 2016.
The project aims to solve the problem of farmland 'white pollution' caused by the complete recovery of the film during use. The full biodegradable film strength developed by the project team reached 35 MPa, the thickness dropped to 4 microns, and the performance index can meet the performance of the film. The cost of the price has been promoted in collaboration with the Ministry of Agriculture, and experimental demonstrations have been completed in most parts of the country.
Project leader, Dr. Wang Hongxue, chief expert of Sinopec Shanghai Petrochemical Research Institute, pointed out that China has made great progress in the production of resin materials, additive development and agricultural film processing technology for agricultural film, but the proportion of high-end agricultural film is much lower. In developed countries, only about 10%. China's high-performance agricultural film new material development, the matching of agricultural film and crop demand, the localization of key additives, the evolution of material structure in the process of agricultural film processing, etc. Room for improvement.
Dr. Wang Hongxue also comprehensively deployed and planned the next task according to the progress of the project: Shanghai Petrochemical Research Institute and Baishan Xifeng Plastic Industry continued to develop multi-functional greenhouse film and biodegradable film development and large-scale production, Shanghai Hongrui Biotechnology Co., Ltd. The company conducts full biodegradable mulch research and large-scale production and promotion. The Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences conducts research and large-scale production of key basic materials. Tsinghua University conducts research and large-scale production of PHA degradation materials, and the University of Science and Technology of China conducts agricultural film processing. Research on the evolution law of material structure in the process.
