Method for recycling urea-formaldehyde (UF) and raw materials from wood-based panel, and use thereof
Patent number: 11958942Abstract: The present disclosure provides a method for recycling urea-formaldehyde (UF) from a wood-based panel. In the present disclosure, the UF is depolymerized by an ultrasonic treatment, and depolymerized UF can be reused for UF manufacture and wood-based panel production. The recycled and treated UF can be repeatedly used in wood-based panel manufacture without affecting performances of the wood-based panel. UF-glued wood-based panels can be recycled, and a recycled wood-based panel raw material can replace at least 50% of a non-recycled wood-based raw material for particle board production without affecting performances of the wood-based panel.Type: GrantFiled: April 10, 2023Date of Patent: April 16, 2024Assignee: Southwest Forestry UniversityInventors: Hui Wan, An Mao, Hong Lei, Xiaojian Zhou, Zhi Li, Long Yang, Linkun Xie, Guanben Du -
Patent number: 11958781Abstract: The present invention discloses potassium sodium bismuth niobate tantalate zirconate ferrite ceramics with non-stoichiometric Nb5+ and a preparation method therefor. A ceramic powder with a general formula of (K0.45936Na0.51764Bi0.023)(Nb0.89958+0.957xTa0.05742Zr0.04Fe0.003)O3 (?0.01?x?0.04) is prepared by a traditional solid phase method; and then piezoelectric ceramics are prepared by traditional electronic ceramic preparation processes such as granulating, molding, binder removal, sintering and silvering test. An excessive amount of Nb5+ doping improves the temperature stability of the ceramics by providing a domain wall pinning effect. This result demonstrates the promise of potassium sodium bismuth niobate tantalate zirconate ferrite ceramics for a wide range of applications, including sensors, actuators, and other electronic devices.Type: GrantFiled: August 16, 2023Date of Patent: April 16, 2024Assignee: Sichuan UniversityInventors: Jianguo Zhu, Hongjiang Li, Jie Xing, Zhi Tan, Lixu Xie

In an initial state, the first inner sleeve blocks the fracturing hole, and the second inner sleeve blocks the nozzle. After an internal flowbore of the second inner sleeve is blocked, a fracturing fluid is pumped into the device. When a pressure reaches a first pressure, the second inner sleeve moves downwards to expose the nozzle and the packer is packed. At this time, perforation can be performed. After perforation is finished, the fracturing fluid is pumped into an annulus. When the pressure reaches a second pressure, the first inner sleeve moves downwards to expose the fracturing hole.Type: ApplicationFiled: January 13, 2017Publication date: June 24, 2021Inventors: Zhenwei GAN, Bin QI, Zhimin HOU, Shunqu HU, Wei LEI, Chen CHEN, Zhi XIE, Qiang WANG, Wei ZHAO, Yijun ZHOU
