  • Publication number: 20250235832
    Abstract: Disclosed are a paddle discarding fully-sealed cement stirring and solidification bucket and a liquid injection and stirring method. A stirring paddle, a bucket cover, and a stirring steel bucket are first assembled and conveyed to a feeding station for cover removal and cement filling; then the stirring steel bucket is conveyed to a stirring station; after a stirring power device, a waste liquid injection device, and a breathing and exhaust device are correspondingly connected to a stirring paddle drive connection end, a waste liquid injection interface, and a breathing and exhaust device interface, injection and stirring of radioactive waste liquid are carried out in a fully-sealed environment. In the present invention, the stirring paddle is discarded in the steel bucket, thereby avoiding the problems of secondary radioactive waste liquid produced by cleaning the stirring paddle and diffusion of radioactive aerosol in the stirring process.

  • Publication number: 20210230128
    Abstract: Disclosed is a blue light absorbing compound, its preparation method and use. The compound has high stability and is suitable for high temperature processing conditions as well as outdoor application. A method of covalently bonding a blue light absorbing compound with an ultraviolet light absorbing compound for increasing its stability is also provided. The compound is capable of absorbing or blocking ultraviolet light (UVA, UVB) and blue light to protect eyes. But long-wavelength blue light can be absorbed diminishingly, so that the transmitted light has a particularly good visual experience.

  • Patent number: 10703734
    Abstract: The present invention discloses a 3-aryl-benzofuranone compound in which R1-R6 in the formula are mutually independent H or C1-C20 alkyls, and R7 is C7-C20 alkyl or C7-C20 mixed alkyl. The present invention also discloses a composition of 3-aryl-benzofuranone compound and the preparation method. The 3-aryl-benzofuranone compound and the composition thereof has the superiority in application due to the characteristics of less proneness to volatilize, less proneness to be extracted, higher resistance to migration and less proneness to bloom and precipitate on the surface of organic materials, and with a wide range of application, it is effective during the application.

  • Publication number: 20200181363
    Abstract: A blue light blocking system including a pyrazoline compound of formula (I) or/and a phenylacrylic compound of formula (II) is provided. The compound of formula (I) or formula (II) can absorb most blue light of shorter wavelength that hurt eyes, but let that of the longer wavelength pass through, so that the transmitted light makes an excellent visual effect for human. The system can be applied to products such as optical films, optical lenses, goggles, skin care, lighting, coatings, adhesives, or panels. These products have a light-colored appearance and their transmitted light makes for an excellent visual effect.
