Patent number: 11970564Abstract: A structural flame retardant high strength low exothermic polymer grouting material for consolidating, belonging to a technical field of polyurethane material, is produced by combined the polyether polyol and the modified isocyanate in a weight ratio of 100:(100-160), leading to internal reaction temperature ?100° C., strength ?60 mPa, bonding ?3 mPa, oxygen index ?28% while no halogen and no effect on water quality, odor level (80° C.) ?3.5, and fog test ?5 mg (which means no physical additive flame retardant is diffused into the environment). In particular, with no halogen, which is known as environmental hormones, in the plasticizers, there will be less combustion smoke, wherein the present invention will not release corrosive or irritating hydrogen halide gas, nor produce toxic carcinogens polybrominated benzoxins and polybrominated dibenzofurans, thereby avoiding the long-term impact of the material on the environment.Type: GrantFiled: September 20, 2022Date of Patent: April 30, 2024Assignees: SAFEKEY Engineering Technology (Zhengzhou), Ltd., Huizhou Mingsheng Chemical Materials Co., LTD., WELEAD Infrastructure Engineering Technology (Zhengzhou), Ltd.Inventors: Peng Zhao, Hongyuan Fang, Lei Wang, Chengchao Guo, Mingrui Du, Chao Zhang, Guobin Qiao

Patent number: 11954895Abstract: The present disclosure discloses a method for automatically identifying south troughs by improved Laplace and relates to the technical field of meteorology. The method includes the following steps: acquiring grid data of a geopotential height field; calculating a gradient field of the geopotential height field in an x direction; searching for a turning point where a gradient value turned from being negative to being positive, and cleaning the gradient field; calculating a divergence of the x direction to obtain an improved Laplacian numerical value L?; performing 0,1 binarization processing on the L? to obtain a black-and-white image and a plurality of targets of potential troughs, merging the black-and-white image and the plurality of targets of the potential troughs by expansion, recovering original scale through erosion, and selecting an effective target through an angle of direction of a contour and an axial ratio.Type: GrantFiled: July 20, 2023Date of Patent: April 9, 2024Assignee: Chengdu University of Information TechnologyInventors: Wendong Hu, Yanqiong Hao, Hongping Shu, Tiangui Xiao, Yan Chen, Ying Zhang, Jian Shao, Jianhong Gan, Yaqiang Wang, Fei Luo, Huahong Li, Balin Xu, Qiyang Peng, Juzhang Ren, Chengchao Li, Tao Zhang, Xiaohang Wen, Chao Wang, Yongkai Zhang, Wenjie Zhou, Jingyi Tao
