Abstract: A fully-automatic aluminum thermal-spraying corrosion prevention production line based on robots and visual recognition is provided. The production line comprises an automatic feeding system comprising feeding carrying and conveying mechanisms; a laser derusting system comprising a derusting robot, a laser cleaning nozzle and derusting conveying mechanisms; an aluminum thermal-spraying system comprising an aluminum spraying robot and an aluminum thermal-spraying gun; an automatic rolling system comprising a rolling pedestal, a first rolling wheel, a second rolling wheel and a rolling drive mechanism; a laser cutting system; and a discharging and stacking system.

Abstract: Disclosed is a high-integration-level plastic tail door, comprising a tail door upper outer plate, a tail light, a tail door lower outer plate, an inner plate, and a high brake light, wherein the tail door upper outer plate, as a whole, is integrated with a spoiler, a tail door windshield, a windscreen decorating member, and a high brake light cover; the tail door upper outer plate is of two layers and is formed by means of double-shot molding, with a first layer being a transparent layer and a second layer being a black non-transparent layer; a first open hole is provided at the position of the high brake light in a black non-transparent layer area; a second open hole is provided in the middle of the tail door windshield; and a hardened coating is arranged on the outer layer of the transparent layer.

Abstract: The present invention discloses a method for efficiently dispersing carbon nanotubes. The method comprises mixing, in parts by mass, 1-30 parts of carbon nanotubes, 0.2-10 parts of functionalized carbon nanotubes and 400-1200 parts of a solvent, adjusting the pH of the resulting mixture to 5-9, and then ultrasonically dispersing the mixture to obtain a stably dispersed carbon nanotube dispersion; the functionalized carbon nanotube is one or more of a carboxylated carbon nanotube, a hydroxylated carbon nanotube, an aminated carbon nanotube, an acyl-chlorinated carbon nanotube, and a sulfonated carbon nanotube.
