The UHPC-based wind power tower comprises a plurality of layers of UHPC tower column units which are arranged in an up-down stacking mode, and each UHPC tower column unit is of a frame type structure with a supporting column as a supporting component; the wind power tower further comprises a plurality of ground anchor beams with applied prestress, and the ground anchor beams are arranged between the UHPC tower column units and a ground foundation. The invention further provides a construction method of the wind power tower with the ground anchor beam. According to the wind power tower structure, under the action of the ground anchor beams, the UHPC tower columns are in a high-pressure stress state, the advantage of high compressive strength of UHPC can be brought into full play, and the stress performance of the UHPC tower columns is improved. A frame type tower column structure with UHPC as a main body material is adopted, the rigidity and the wind resistance stability are higher, the self weight is low, the height can be higher, and the fatigue resistance and the durability are good.

This invention relates to an environmentally friendly water-based composite flame retardant and its preparation method, belonging to the field of flame retardant preparation technology. The environmentally friendly water-based composite flame retardant formulation is as follows: by weight percentage, modified graphene 1.5-3.0%, nano-magnesium hydroxide 8-12%, nano-sodium silicate 5-8%, surfactant 0.5-1.0%, and the balance being deionized water. Modified graphene, nano-magnesium hydroxide, and sodium silicate produce a synergistic flame-retardant effect. Modified graphene builds a dense carbon layer framework, magnesium hydroxide decomposes endothermally, and magnesium oxide acts as a barrier to reflect heat radiation, while sodium silicate promotes the formation of a silicate glassy carbon layer. The combination of these three components significantly improves the oxygen index of the material. The flame retardant prepared by this invention possesses both excellent thermal conductivity and environmentally friendly properties, and can be widely used in fire fighting and flame retardant applications.

This invention relates to the field of cup rim spinning technology, and discloses a cup rim spinning device for insulated cups, including a mounting frame, a rotating base, a horizontal plate, a first cylinder, a drive motor, a U-shaped bracket, and a spinning disc mounted on the mounting frame. It also includes a precision spinning mechanism disposed on the horizontal plate, comprising a fixed sleeve, an extrusion shaft slidably disposed within the fixed sleeve, and a pressure plate fixed to the extrusion shaft via a cross-shaped connecting plate. Through the cooperation of the extrusion shaft, pressure plate, pressure cap, first ball bearings, ring plate, and bushing, when the extrusion shaft presses down, the pressure plate and elastic element drive multiple first ball bearings at the bottom of the pressure cap to evenly abut against the ring plate, stably transmitting vertical pressure to the bushing and main shaft. This effectively reduces the deflection vibration of the main shaft during spinning, significantly improves the spinning accuracy of the spinning disc, and solves the problem of poor cup rim forming quality caused by insufficient main shaft accuracy in traditional equipment.
