Abstract: The present disclosure provides a superhydrophobic and self-cleaning anticoagulant composite coating material and a preparation method and use thereof, and relates to the technical field of biomedical materials. In the coating material provided by the present disclosure, a titanium dioxide nanotube-based structure increases microscopic roughness of a surface of a titanium-based metal substrate, and a hydrophobic modification layer reduces surface energy of the material. The rough structure and the hydrophobic modification layer have a synergistic effect to construct a superhydrophobic surface, making the surface of the material have self-cleaning characteristics and low adhesion. Air can be retained on the surface of the material to form an air layer, thereby reducing the contact area between the material and bacteria and platelets in the blood, and inhibiting adhesion of the bacteria, platelets, and plasma proteins to the material.

Abstract: An automatic forming machine for a pulp molding product and a manufacturing method therefor. During manufacturing, a slurry suction mold immersed in a slurry box suctions a slurry to form a slurry layer, and then ascends to leave the slurry box to assemble with an upper hot pressing mold, which moves in from an external space, for extrusion to form a preform; then the slurry suction mold descends into the slurry box for a second round of slurry suction; the upper hot pressing mold suctions the preform and returns in a reverse direction to an original position; then a lower hot pressing mold ascends for assembling to hot press and shape the preform to form a pulp molding product, and the lower hot pressing mold suctions the pulp molding product and descends to the original position; and a material receiving mechanism then suctions the pulp molding product and leaves the lower hot pressing mold for separate collection.

Abstract: Disclosed are a self-positioning assembly system for rapid assembly of an aircraft and a method thereof. The self-positioning assembly system includes a mounting platform, a framework assembly, a hole positioner assembly, a strut positioner assembly and a pallet assembly. The framework assembly is mounted on the mounting platform and includes a hole positioner column and a pallet column, the hole positioner assembly is arranged on the hole positioner column, the pallet assembly is arranged on the pallet column, a plurality of the hole positioner columns are respectively arranged on both sides of the mounting platform, and a plurality of the pallet columns are arranged in a middle of the mounting platform.

Abstract: Disclosed is a molded pulp cup lid made of a material which is a mixture of paper pulp and/or plant fibers. The molded pulp cup lid is manufactured by a mold with pulp suction molding and hot pressing technologies, and has a binding edge capable of covering the cup securely, an offset cup top, and a drinking opening formed on a high platform to achieve the effects of preventing a liquid contained in the cup from spilling to the outside, facilitating users to carry or move the stacked takeout paper cups, and retarding the flow of the beverage at the drinking opening.
