Publication number: 20240114936Abstract: The present disclosure provides a preparation method of an easy-to-cook whole grain based on microwave-induced cracking, and belongs to the technical field of food processing. In the present disclosure, the preparation method of an easy-to-cook whole grain includes the following steps: subjecting a whole grain to a heat-moisture treatment, and conducting short-time microwave-induced cracking, tempering, and cooling to obtain the easy-to-cook whole grain. The easy-to-cook whole grain obtained by the preparation method of the present disclosure has a complete grain, a slightly-expanded volume, and fine cracks on its surface. Compared with unprocessed whole grains, the easy-to-cook whole grain has a water absorption increased from 1.35 times to 1.9 times an original weight of the unprocessed whole grains during rice steaming.Type: ApplicationFiled: September 8, 2023Publication date: April 11, 2024Inventors: Shuwen LU, Chuanying REN, Bin HONG, Shan ZHANG, Dixin SHA, Junran FENG, Di YUAN, Bo LI

Patent number: 11845896Abstract: A structural stabilizer for a fiber and proppant complex to enhance proppant migration and placement in a fractured well during propping and a preparation method thereof are provided. The structural stabilizer consists of: water, inorganic salt, kaolinite, nitrogen-doped modified graphene oxide, anionic surfactant, non-ionic alkyl polyglucoside, and polyacrylamide. The structural stabilizer improves bonding between a proppant and a fiber when slick water is used in stimulated reservoir volume (SRV) fracturing, prevents separation of the fiber and the proppant during migration, thereby reducing escape rate of the fiber from the fiber and proppant complex.Type: GrantFiled: July 13, 2023Date of Patent: December 19, 2023Assignees: Chengdu LEPS Technology Co., Ltd, Southwest Petroleum UniversityInventors: Jianchun Guo, Shan Ren, Hao Yang, Yingxian Ma, Kun Wang, Jiyu Wang, Cong Lu, Jiapeng Zhang, Zhihong Zhao, Shaobin Zhang, Qianli Lu, Qingsong Guo, Su Diao, Chi Chen, Xin Lei, Mingyuan Zhou, Chaojun Tang

Patent number: 9382156Abstract: Embodiments of the present disclosure are directed to a low density monolithic fiber cement article that incorporates controlled air entrainment evenly distributed throughout the article to improve various physical properties of the article. In some implementations, air entrainment agents are used to create voids in the article, thereby lowering the density and weight of the boards while maintaining adequate strength. In some implementations, the air entrainment agents can be added in solution to create a foam, or can be used to generate a pre-foam, which can be added to a cementitious paste. The cementitious paste incorporating the air entrainment agent can proceed through an extrusion process, experiencing high pressures, where the voids remain in the final monolithic fiber cement board.Type: GrantFiled: November 30, 2012Date of Patent: July 5, 2016Assignee: James Hardie Technology LimitedInventors: Shan Ren, Jongmin Keum, Bhavin Mehta, Eoin Battles
