The invention relates to the field of solid waste resource utilization research, in particular to colored self-leveling red-mud-based fully-recycled high-strength mortar and a preparation method thereof, and the colored self-leveling red-mud-based fully-recycled high-strength mortar comprises the following components in parts by mass: 60-100 parts of solid waste cementing material, 30-50 parts of mortar recycled aggregate, 5-10 parts of recycled pigment and 2-10 parts of self-leveling agent. By adopting the colored self-leveling red-mud-based fully-regenerated high-strength mortar material disclosed by the invention, a large amount of industrial solid wastes such as red mud, construction wastes and waste pigments can be recycled, the material is convenient and efficient to construct, high in strength and good in flowability, the dependence on natural raw materials can be reduced, the cyclic utilization of solid waste resources is promoted, and the cost is reduced. Therefore, carbon emission is reduced, environmental pollution is reduced, more material choices are provided for the building industry, and different engineering requirements are met.

This invention belongs to the field of micro-coating protection and discloses an organosilicon aerosol coating for waterproofing precision instruments and its preparation method. The organosilicon aerosol coating comprises, by weight, 4-6 parts of fluorinated organosilicon, 2-3 parts of organosilicon-acrylate resin, 30-40 parts of a first solvent, 20-30 parts of a second solvent, 1-1.5 parts of a release agent, 0.5-1 parts of a leveling agent, and a certain amount of propellant. This invention uses a first solvent and a second solvent with different volatility properties to improve the self-leveling and film-forming quality of the microfilm after spraying, reducing surface micropore defects caused by excessive evaporation and forming a good waterproof layer. Through the synergistic effect of fluorinated organosilicon and organosilicon-acrylate resin as film-forming materials, the waterproof coating formed with the release agent and leveling agent possesses both long-lasting waterproofing and peelability. When used for the protection of precision instruments, the coating can be peeled off after a certain protection period without leaving residual pollution on the instrument surface.

The invention discloses a high-strength machine mahjong and a manufacturing method thereof, and mainly relates to the technical field of mahjong machines. The machine mahjong comprises a mahjong shell, a magnet is arranged in the mahjong shell, filler is arranged between the magnet and the inner wall of the mahjong shell, a font groove is formed in the front face of the mahjong shell, and fonts are poured in the font groove. According to the invention, a paint process for coloring the mahjong font patterns is changed into a pouring process, so that the mechanical strength, old resistance, dirt resistance, corrosion resistance and other index performances of the mahjong font patterns are greatly improved.
