The invention discloses a high-performance 4.5-micron electrolytic copper foil additive and application thereof, and belongs to the technical field of electrolytic copper foils. The additive comprises cerium-polyacrylamide composite microspheres, a sulfur-containing brightener, a leveling agent, a wetting agent and the like, the cerium-polyacrylamide composite microspheres are inorganic-organic composite materials formed by rare earth element cerium and polyacrylamide, and the cerium-polyacrylamide composite microspheres are prepared through an in-situ polymerization method. Monomer acrylamide of polyacrylamide grows around cerium ions in situ, so that the cerium ions are fixed around a polymer chain, and a relatively stable dispersion system is formed. The 4.5-micron electrolytic copper foil prepared by adopting the additive has good surface quality and relatively high tensile strength and ductility. Particularly, the tensile strength and the elongation performance can reach 400-500 MPa and 6% or above respectively, and the production and application reliability of the 4.5-micron copper foil is greatly improved.

The utility model discloses a home decoration seam beautifying tool which comprises a supporting frame, the supporting frame is of a rectangular frame structure, a supporting seat is arranged on one side of the supporting frame in a protruding and welding mode, a pushing handle is connected to the supporting seat, a placing frame is arranged on one side of the supporting frame, a glue bearing cylinder is placed on the placing frame, and a glue outlet is formed in the glue bearing cylinder. The end part of the glue bearing cylinder is connected with a glue feeding nozzle; the utility model relates to the technical field of home decoration tools, the home decoration seam beautifying tool is supported by a frame of a roller structure, two mechanisms of gluing and seam beautifying are integrated, a supporting frame can be pushed through a heightened pushing handle, pressing of gluing can also be completed, workers do not need to bend down too low, and the working efficiency is greatly improved. And meanwhile, after gluing is completed, filling and seam beautifying are conducted on the gluing position through the height-adjustable smoothing assembly, two kinds of operation are completed through one-time bending, efficiency is improved, and seam beautifying work can be completed more accurately and efficiently in cooperation with the arrangement of the guide rod with the guiding function.

This utility model relates to the technical field of material conveying equipment, and in particular to a material conveying control mechanism for cement plants. It includes a chute for conveying materials, a conveniently located box-type feeder below the chute, a material hopper on the box-type feeder, and further includes: a transfer hopper connected to the output end of the chute; an inlet pipe connected to the output end of the transfer hopper, with several outlet pipes connected to the output end of the inlet pipe. The box-type feeder is located at the output end of the outlet pipes. A material conveying control component controls a gate connected to the outlet pipes, thereby controlling the discharge sequence and opening / closing of the several outlet pipes. Under the action of sensors, the material conveying control component can sequentially feed materials to several box-type feeders without worker supervision. Compared to existing material conveying methods, this device's material conveying mechanism can automatically control the material conveying process.
