This invention discloses a noise-canceling earmuff and protective assembly, relating to the technical field of safety protection devices. The noise-canceling earmuff includes a shell, a sound-absorbing component, and a cover. The shell has a receiving cavity and an opening communicating with the receiving cavity. At least a portion of the cavity wall forms a honeycomb-shaped noise-canceling structure. The sound-absorbing component is installed in the receiving cavity and conforms to the cavity wall. The cover is a sealing cap located at the opening and has a material replacement port for removing and placing the sound-absorbing component. The technical solution provided by this invention aims to improve the noise-canceling effect of the earmuff and ensure a better user experience.

This utility model discloses a screen structure and a high-gain white screen, belonging to the field of projection display technology. The screen structure includes two substrate layers, with a barrier layer bonded between the two substrate layers via an adhesive layer. The substrate layers, adhesive layer, and barrier layer have different refractive indices. The high-gain white screen includes a protective layer, a diffusion layer, and the aforementioned screen structure, arranged sequentially from the incident surface to the back surface. By utilizing the difference in refractive indices between the substrate layer, adhesive layer, and barrier layer, an optical effect similar to mother-of-pearl is created, reducing light penetration and enhancing light reflection and scattering. This improves detail rendering, reduces the loss of dark areas, enhances resistance to external light interference, reduces contrast, reduces color saturation distortion, reduces light loss during propagation, improves overall brightness uniformity, ensures full presentation of high-resolution signal details, and is compatible with more projection devices.

This invention discloses a composite functional coating for UTG flexible glass, its preparation method, and its application, belonging to the field of glass surface treatment technology. It includes a high refractive index matching layer disposed on the surface of the UTG flexible glass, and a low refractive index hydrophobic reinforcement layer disposed on the surface of the high refractive index matching layer. The high refractive index matching layer is formed by heat treatment of a silane coupling agent-modified nano-zirconium dioxide and nano-silica composite sol. The low refractive index hydrophobic reinforcement layer is obtained by stacking two types of silica nanospheres with different particle sizes and in-situ modification with perfluoroalkylsilane. The coating of this invention enables the UTG flexible glass to achieve an average transmittance of over 95.3% in the 380-1100nm wavelength range, a water contact angle >150°, and a performance retention rate of over 95% after 1500 hours of UV aging and dry brushing. It also exhibits grade 0 adhesion, bend resistance, and fully meets the stringent requirements of various high-end flexible optoelectronic devices for high transmittance, durable self-cleaning, and weather-resistant toughness of the substrate glass.

This invention discloses a cross-linked polyethylene insulation material for medium-voltage DC cables and its preparation method. By weight, it comprises the following raw materials: 100-110 parts LDPE, 5-8 parts modified filler, 0.4-0.6 parts antioxidant, 0.2-0.3 parts cross-linking aid, and 0.4-0.7 parts initiator. The modified filler, prepared by a specific method, combined with an optimized cross-linking and antioxidant system, significantly improves the overall performance of the insulation material. This modified filler, through the synergistic effect of its deep trap energy levels in the core and the shallow trap energy levels of the outer organic molecules, increases the DC resistivity and breakdown field strength of the material. Simultaneously, the flexible long-chain structure grafted onto the filler surface improves its interfacial compatibility with the polyethylene matrix, giving the material excellent mechanical properties that meet the stringent requirements for long-term safe and stable operation of medium-voltage DC cables.
