In the process of chemical production, material preparation and pesticide dispersion, the liquid/solid composite system has a poor interface and structure due to different composition and structure, and there are common problems in liquid-solid separation, system instability and performance degradation. Nanjing Normal University and Wanhua Chemical Co., Ltd. Through systematic research, the unit reveals the mechanism of maintaining stability, determines the factors that affect stability, and develops the technology of ternary copolymer structure optimization and particle size distribution dynamic control, and successfully promotes its application.
The project invented the ternary copolymer structure optimization technology, applied to the preparation of coal water slurry, improved the molecular chain flexibility, enhanced the salt resistance, improved the adsorption strength with the coal surface, and optimized the dispersion of coal in water. It breaks through the bottleneck of the low-rank coal in China and is difficult to be made into high-concentration coal-water slurry. It is applied to the preparation of filled polyolefin, avoiding interface debonding and performance degradation, and achieving enhanced toughening. It is applied to the dispersion of pesticides, improves the dispersion stability of the original drug, improves the spreadability of pesticides on the surface of plants, and achieves reduction, high efficiency and income increase.
For the first time, the technology for dynamically regulating the optimal distribution of solid particle size is used in industrial production to achieve close packing of solid particles, improving the flow properties and mechanical properties of filled polyolefins, reducing costs, and prolonging the high concentration of water coal in difficult-to-pulp coal types. The continuous production cycle of pulp preparation increases economic efficiency.
He has published 30 high-level papers, and he has been cited 1537 times by the world's top academic journals, authorizing 7 Chinese invention patents and 2 Chinese software copyrights. In the past three years, it has added sales of 8.04 billion yuan and added profits of 1.67 billion yuan. It has promoted the scientific and technological progress of related industries and was evaluated as “the overall level of international advanced level and reached the international leading level in the application of coal water slurryâ€.
