Patent number: 11091565Abstract: The present disclosure relates to the technical field of building additives, and in particular to a preparation method of modified starch ether for improving the anti-sliding property of a ceramic tile adhesive. The preparation method includes chemical modification of subjecting starch to one-step etherification to obtain starch ether, followed by physical modification. In the preparation method, the cumbersome multi-step etherification in existing methods for preparing modified starch ether is avoided, and only one-step etherification is used to obtain modified starch ether of better properties. Because physical modification is added, the obtained product can significantly improve the anti-sliding property of a ceramic tile adhesive. Moreover, the conditions for one-step etherification are significantly different from the prior art.Type: GrantFiled: September 25, 2020Date of Patent: August 17, 2021Assignee: Shandong Eton New Material Co., Ltd.Inventors: Kun Teng, Ming Zhao, Qinghua Li, Changyin Li, Maofeng Li, Hongshan Zhao, Kaimin Zhang

Publication number: 20050233076Abstract: An apparatus (20) for supporting a substrate (S2) includes a number of slats (28), a number of connecting blocks (24) separately positioned on the slats, and a number of soft sleeves (22) connected with the connecting blocks, respectively. Because top surfaces of the soft sleeves are shaped as annular, the force applied between the substrate and the soft sleeves is distributed, and is reduced at each contact point. The surface of the substrate is hardly if at all deformed by the soft sleeves, thereby reducing the risk of or even altogether preventing the formation of undulations. The quality of the pattern to be processed is improved.Type: ApplicationFiled: April 20, 2005Publication date: October 20, 2005Inventors: Shao-Ming Hsu, Ching-Lung Wang, Wen-Cheng Hsu, Yu-Ying Chan, Tseng-Kuei Tseng, Ho-Li Hsieh, Chen-Kun Teng

Publication number: 20040124060Abstract: A wheel driving device for a pedal propelled cycle, includes an axle coupled with cranks and driven to rotate synchronously by a pedaling force. A coupling socket is movable axially as a result of a rotation of the axle between a fully engaged position, where it is in a full threaded engagement with the axle and frictionally engages a hub shell so as to move a wheel body forward, and a partially engaged position, where it is in a partial threaded engagement with the axle as a result of a screwing-out movement due to backpedaling, and disengages from the hub shell so as to place the wheel body in a freewheeling state. Further backpedaling results in a frictional engagement of the coupling socket with a brake member so as to brake the hub shell and the wheel body.Type: ApplicationFiled: December 30, 2002Publication date: July 1, 2004Inventor: Kun-Teng Chen
