This invention discloses a silicate colloid for high-solids-content, high-modulus composite fire-resistant glass and its preparation method, relating to the field of composite fire-resistant glass technology. Specifically, it describes a silicate colloid for high-solids-content, high-modulus composite fire-resistant glass and its preparation method. The colloid, by weight percentage, comprises a silicon source, water, glycerol / ethylene glycol / polyethylene glycol / polyglycerol, water-soluble organic acids and salts, water-soluble metal oxides or hydroxides, and alkali metal hydroxides, wherein the solids content is 60-75% and the modulus is 4.0-5.5. The preparation method includes: uniformly mixing the silicon source, water, additives, and functional additives, then adding alkali metal hydroxides, reacting at 50-90°C to obtain a prepolymer solution, followed by vacuum degassing. The viscosity is adjusted to the desired range by controlling the reaction conditions. This prepolymer solution is suitable for pouring or coating processes. After curing, the colloid forms a fire-resistant glass core layer. The resulting fire-resistant glass has advantages such as high light transmittance, ultra-thinness, dense foaming, low-temperature resistance, high weather resistance, and long lifespan.

The invention relates to the technical field of civil engineering materials, and discloses a freeze-thaw resistant roadbed curing agent with phase change energy storage and self-repairing functions and a preparation method thereof.The freeze-thaw resistant roadbed curing agent comprises a curing component, a phase change energy storage component and a self-repairing component, and the curing component comprises, by weight, 50-80 parts of mineral powder, 20-40 parts of fly ash and 30-40 parts of carbide slag; the phase change energy storage component is prepared from the following components in parts by weight: 10 to 20 parts of n-dodecane, 5 to 18 parts of tetraethoxysilane, 0.1 to 0.5 part of lauryl sodium sulfate, 70 to 90 parts of fiber, 1 to 5 parts of waterborne polyurethane and 130 to 160 parts of deionized water; the self-repairing component comprises epoxy resin. The roadbed filling material has freeze-thaw resistance, self-repairing capability and temperature buffer function, can significantly improve the mechanical properties and durability of roadbed soil under freeze-thaw cycle, and is suitable for roadbed filling material solidification in cold and severe cold areas.

The application relates to the battery technical field, and provides a battery monomer, a battery device and a power utilization equipment. The battery monomer comprises a shell, an electrode assembly and a cladding piece. The electrode assembly is arranged in the shell; wherein the electrode assembly comprises a first pole piece, a second pole piece and a separator; one of the first pole piece and the second pole piece is a positive pole piece, and the other is a negative pole piece; the separator is arranged between the first pole piece and the second pole piece; the first pole piece, the separator and the second pole piece are stacked and wound; the cladding piece is wrapped on the outer ring of the electrode assembly; the cladding piece is wrapped on more than one ring of the electrode assembly; the first pole piece, the separator and the second pole piece are stacked and wound, so that the electrode assembly forms a flat area and a bending area connected to both ends of the flat area; the end position of the cladding piece and the starting position of the cladding piece form an overlapping area along the winding direction of the cladding piece, and the overlapping area is at least partially located in the bending area. The cladding piece can limit the rebound force of the bending area, and reduce the possibility of pole piece fracture and lithium precipitation.
