The invention relates to a concrete self-curing agent as well as a preparation method and application thereof. The concrete self-curing agent is prepared from the following raw materials in parts by weight: 200 parts of water; 10 to 25 parts of ethylene/vinyl acetate copolymer; 10 to 25 parts of sodium polyacrylate; 35 to 45 parts of polyglutamic acid; 5 to 15 parts of chitosan; and 5-20 parts of sodium pyrosulfite. The raw material components of the concrete self-curing agent can effectively solve the problems of too fast water loss, drying shrinkage and the like of concrete in the curing process due to the influence of an external environment through the combined action of film forming, water retention, wetting and the like, so that the concrete added with the concrete self-curing agent has a self-curing function, external watering curing is not needed in the curing process, and the cost is reduced. Compared with the prior art, labor cost and water pumping power consumption cost can be ...

The ship lock management and control integrated system comprises a ship lock monitoring unit, a navigation management unit, a data interaction intermediate library, a network communication isolation device and a data synchronization tool. Data of a ship lock monitoring unit and a navigation management unit which are respectively constructed are automatically and organically interacted, so that gear information of passing ships in a shipping hub can automatically arrive at the ship lock monitoring unit, and meanwhile, the ship lock monitoring unit automatically uploads the ship passing information to the navigation management unit in real time; and the operation efficiency of the ship lock is also improved while the risk caused by human intervention on the navigation process is avoided.

The invention relates to a surface modified glass bead composite filler as well as a preparation method and application thereof, and belongs to the technical field of polymer composite materials. The preparation method of the surface-modified glass bead composite filler comprises the following steps: by taking glass beads as a raw material, firstly treating the glass beads with an aqueous solution of a pretreating agent, then treating the glass beads with a surfactant, then forming gel with potassium silicate water glass, and finally aging, suction-filtering, washing and drying the gel to obtain the surface-modified glass bead composite filler. The surface modified glass bead composite filler can greatly enhance the interface bonding force between a polymer and glass beads. The invention also provides application of the surface modified glass bead composite filler in preparation of a thermoplastic polyurethane elastomer composite material, and the prepared thermoplastic polyurethane elastomer ...
