Abstract: A ternary composite catalyst of diethylzinc and yttrium trifluoroacetate loaded on chitin for copolymerization of carbon dioxide, epoxy cyclohexane and ethylene oxide is provided. The ternary composite catalyst exhibits strong catalytic activity for the ternary copolymerization of carbon dioxide, cyclohexane oxide and ethylene oxide. A high molecular weight and content of ester chain is maintained. Conventional rare earth ternary catalysts leave residues in the polymer, and the polymer requires rinsing with hydrochloric acid. The ternary composite catalyst can be removed through filtration. The average molecular weight of the resulting polycarbonate is more than 100,000, and the ester chain content is more than 90%. The resulting polymer has a lower metal content. The ternary composite catalyst can be used in agricultural film, disposable packaging and other polymer materials.

Abstract: A flow splitting device for gas reverse circulation drilling, including: an upper joint for connecting with a double-wall drill pipe; an inner tube which is arranged in the upper joint and defines a first passageway in communication with an inner chamber of the double-wall drill pipe, a second passageway in communication with an annular space in the double-wall drill pipe formed between the inner tube and the upper joint; a lower joint, having an upper end fixedly connected with the upper joint and a lower end for connecting with a drill tool; and a flow guiding member provided between the upper joint and the lower joint. A flexible sealing mechanism is provided outside the upper joint. The flexible sealing mechanism extends radially outward relative to the upper joint and the lower joint to form a sealing contact with a wellbore wall.

Abstract: An electronic-grade glass fiber composition includes the following components with corresponding amounts by weight percentages 51.0-57.5% SiO2, 11.0-17.0% Al2O3, >4.5% and ?6.4% B2O3, 19.5-24.8% CaO, 0.1-1.9% MgO, 0.05-1.2% R2O=Na2O+K2O+Li2O, 0.05-0.8% Fe2O3, 0.01-1.0% TiO2, and 0.01-1.0% F2.

The A valve core is arranged in the A cavity, and the B valve core is arranged in the B cavity.

Abstract: Provided is an ultraviolet absorption glass comprising: a glass substrate, and an ultraviolet absorption coating arranged on at least one surface of the glass substrate, wherein the ultraviolet absorption coating comprises silicon dioxide, an ultraviolet absorber, and MOz used for storing and releasing electrons excited by ultraviolet light in the ultraviolet absorber. The ultraviolet absorption glass is low cost and has good resistance to discoloration and devitrification.

Abstract: Coating liquid used for forming an ultraviolet absorption coating on a surface of an object such as glass and the like, ultraviolet absorption glass arranged with the ultraviolet absorption coating formed by the coating liquid, and a method for preparing the ultraviolet absorption glass. The coating liquid used for forming the ultraviolet absorption coating, the ultraviolet absorption glass and the method for forming the ultraviolet absorption glass, by storing and releasing electrons excited by ultraviolet lights in an ultraviolet absorber, reduce the excited electrons that are gradually accumulated during a process in which the ultraviolet absorber absorbs the ultraviolet lights, thus protecting the ultraviolet absorber and a silicon dioxide matrix, preventing the ultraviolet absorption glass from discoloring or devitrifying, ensuring weather resistance of the ultraviolet absorption coating and ensuring color consistency of the ultraviolet absorption glass.
