  • Publication number: 20210115600
    Abstract: Described herein is a weft-knitted spacer fabric and a preparation method thereof, a polyurethane foam composite material comprising including the fabric, a preparation method of the composite material and its use in shoe materials. The weft-knitted spacer fabric consists of an upper surface layer, intermediate spacer yarns, and a lower surface layer, and the upper surface and the lower surface layer are connected by the tuck of the spacer yarns in the upper surface and the lower surface layer to form a three-dimensional structure in an integrated manner. The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns.

  • Publication number: 20200352621
    Abstract: A thermal resistance heater with a thermal conductive shell that is used to contact with tumor tissues and conduct heat therefor is provided. A thermal resistance is disposed inside the thermal conductive shell and is self-heated via current. The thermal energy is converted from the electrical energy according to Joule's Law. The heater includes a heat radiator disposed inside the shell and is used to disperse the heat generated by the thermal resistance and conduct the heat to the shell evenly. A thermal-conduction compensation arm and the heat radiator are contacted for achieving that a temperature of the shell is the same with a specific place or an error there-between is within a threshold. A temperature sensor is used to obtain a surface average temperature of the conductive shell by collecting temperatures over the thermal-conduction compensation arm.

  • Patent number: 10814314
    Abstract: The present invention relates to a catalyst for aminating a polyether polyol and preparation method thereof and a method of preparing a polyetheramine using the catalyst. The catalyst has active components and a carrier. The active components are Ni, Cu, and Pd. The method of preparing the catalyst comprises the following steps: using a metal solution or a metal melt impregnated carrier, obtaining a catalyst precursor; and drying and calcinating the obtained catalyst precursor, so as to obtain a catalyst. By introducing the active component Pd in the catalyst, the present invention clearly improves selectivity of an amination catalyst with respect to a preaminated product, and increases raw material conversion rate.
