The Intellectual Property Office of China recently authorized that the “Ship to Gate Wall Friction Test System†jointly declared by Hohai University, Nanjing Hohai Technology Co., Ltd. and Yangzhou Waterway Management Office of Jiangsu Province has obtained an invention patent.
"Ship-to-lock wall friction test system" can accurately measure and record the contact time between the ship and the lock wall, and the dynamic changes of the friction force during the friction process. It has the characteristics of simple structure and easy manufacture, maintenance and use. This system, combined with finite element software simulation, can be used as a tool for the study of the frictional force of the ship against the gate wall, and provides a basis for the strength index and ratio of the concrete of the gate wall during the design, construction, maintenance and management of the gate.
Plastic relative to the ceramic tableware, Silicone Tableware, hardware, silica gel tableware harmony together with temperature, in which food is cold is hot, can protect the temperature of the food itself, reduce the loss of the change of temperature and a period of time in the silicone bowl or pot food can still maintain the original temperature, when use won't convey the temperature of the corresponding to the user. Moreover, the particularity of the silicone material itself, which is different from other materials, makes the products produced by it have an amazing effect. For example, landing silent food containers, after high temperature cooking, will not produce harmful substances. And tableware but fold, can knead, can turn over, chuai also does not take a space in the pocket, also won't adsorb smeary. Its own desiccant effect, will not because of long-term storage and moldy, qualitative change.
And because of silica gel temperature resistant properties, heat resistance of 240 ℃ high temperature deformation, won't produce hardening phenomenon to 40 ℃, so the product is fully staffed, very practical, we don't have to classification of casual in a microwave, don't worry about the melting and aging and yellowing phenomenon, and it is easy washing, can use less or even do not use detergent containing chemical substances, practicability and convenience are very strong, very suitable for use in their life.
