  • Publication number: 20240091739
    Abstract: Provided are a mercapto group-loaded layered double hydroxide (LDH)-based magnetic composite particle, and a preparation method and use thereof. The method includes: dissolving a water-soluble divalent magnesium salt and a water-soluble trivalent aluminum salt in water to obtain a mixed salt solution; pumping ammonia water into the mixed salt solution, and performing reaction I under stirring, subjecting an obtained product to centrifugation, and washing product obtained with deionized water; mixing the product with water, ethanol, and a coupling agent KH-580 to obtain a mixture, subjecting the mixture to reaction II while stirring to obtain mercapto group-loaded LDH; mixing the mercapto group-loaded LDH with ferroferric oxide and sodium alginate, adding deionized water thereto, and stirring to obtain a homogeneous mixed solution; adding the homogeneous mixed solution into a calcium chloride solution dropwise to form a magnetic bead; and leaving the magnetic bead to harden, and then washing and drying.

  • Patent number: 11002051
    Abstract: A space-saving lengthwise and widthwise movable panel system capable of being fully opened belongs to the field of smart building technology and includes a lengthwise panel moving compartment, a panel storage space and a panel control module. The movable panel system can be used as a door and/or window system. All of the panels of the system can be entirely stored in the panel storage space and when storing all of the panels entirely in the panel storage space, the panel system is fully open to allow full lengthwise access to a space. The panel storage space may be located in a wall or outside the room to hide the stacked panels. By controlling the operation of the moving system, the panels are effectively connected to one another in an aligned manner and can move automatically, so the space-saving movable panel system is convenient to use, and space-saving.

  • Publication number: 20190376330
    Abstract: A space-saving movable door/window system capable of being fully opened which belongs to the field of smart building technology includes a door/window panel mounting space, a door/window panel storage space and a door/window panel control module. The present invention adopts a lengthwise and widthwise moving system. All of the door/window panels can be entirely stored in the door/window panel storage space, making the door/window fully opened to spare all the occupied space. The door/window panel storage space may be located in a wall or outside the room to hide the stacked door/window panels. By controlling the operations of the moving system and the control system, the door/window panels are effectively connected to one another in an aligned manner and can move automatically, so the space-saving movable door/window system is convenient to use, space-saving, and can effectively improve space utilization ratio.
