This application relates to a zinc-aluminum-magnesium rare earth alloy coating, its coating method in steel wire, and steel wire rope. The zinc-aluminum-magnesium rare earth alloy coating comprises: Al, Mg, at least one microalloying element selected from Nb, Ti, and V, rare earth elements, with the balance being Zn and unavoidable impurities; the rare earth elements are introduced into the coating in the form of organic rare earth compounds. In the coating of this application, during the hot-dip galvanizing process, the organic rare earth compounds undergo thermal decomposition, releasing active rare earth atoms in situ. The CO and H2 generated by the cracking of the organic groups constitute a micro-reducing atmosphere that protects the rare earth from secondary oxidation. The release of rare earth atoms at the interface improves the wettability of the plating solution to the steel substrate, reduces residual oxide films, purifies grain boundaries, and trace amounts of carbon form a RE-C grain boundary composite segregation layer with the rare earth, thereby improving the performance of the steel wire product.

The packaging coating material provided by the present application is fully biobased and degradable, and a small amount of ethylene-acrylic acid copolymer is used, so that the overall coating can be completely degraded in industrial composting, the prepared coating has the effects of waterproofing, oil-proofing, oxygen and moisture resistance and ultraviolet shielding, and has a balance between rigidity and toughness.

This invention discloses a vibration-type respiratory sputum clearance device, relating to the field of medical device technology. It includes a vest body. Multiple independent liquid-coupled vibration units are arranged on the inner side of the vest, corresponding to the upper and lower lobes of both lungs and the projected lung region on the back. Each liquid-coupled vibration unit includes a sealed liquid-sealed bag, and a vibration unit is disposed on the outer side of each sealed liquid-sealed bag. The sealed liquid-sealed bag is integrally embedded and fixed in a flexible interlayer on the inner side of the vest. The interior of the sealed liquid-sealed bag is filled with a vibration-transmitting liquid. The vibration-transmitting liquid filled in the sealed liquid-sealed bag of this invention, relying on its incompressible and highly fluid physical properties, can efficiently transmit and convert the high-frequency micro-vibrations generated by the double-layer piezoelectric sheet, forming a dual mechanical action of shallow loosening and deep oscillation, perfectly adapting to the sputum clearance needs of the soft tissues of the chest and back and the deep airways of the thoracic cavity.
