The invention discloses liquid metal with the anti-fusion feature and for under the temperature of 54-61 DEG C. The metal is composed of, by weight, 4-28% of Sb, 1-10% of Bi, 1-30% of Sn, 0.2-0.4% of Ag, 2-3% of Zn, 0.2-6% of La and the balance In. Within the range of the temperature 54-61 DEG C, the liquid metal is in a solid-liquid state and has enough viscosity. When the temperature is higher than 62-64 DEG C, the anti-fusion phenomenon occurs due to the fact that the content of a solid phase is increased, and thus solidification is generated. Based on the effect that the heat transfer property and thermodynamic property of liquid metal for an existing computer chip with the temperature being about 59 DEG C are ensured, the feature of multi-phase alloy generating anti-fusion behaviors after the temperature is increased again is introduced to liquid metal design, and the range of alloy components suitable for heat dissipation within the range of 54-61 DEG C is appointed. After the temperature is higher than 62-64 DEG C, the liquid metal conducts the anti-fusion behaviors due to the fact that the content of the solid phase is increased. Therefore, it is ensured that the liquid metal cannot laterally leak in the using process of the computer chip, and thus safety of heat dissipation is improved.

The invention proposes a concrete quick-setting agent, which is prepared from the following raw materials: aluminum sulfate, aluminum nitrate, phosphoric acid, ammonia water, halloysite nanotube modified alkanolamine polymer grinding aid, stabilizer, magnesium fluorosilicate , tackifier, water. The invention combines various coagulation-accelerating components, which can further shorten the setting time of shotcrete and improve the comprehensive performance of cement. It has a good coagulation-accelerating effect on ready-mixed concrete that has already undergone initial hydration, and can significantly shorten the coagulation of concrete. Time, improve the early strength, but also significantly improve the stability, durability and safety of concrete, and the cost is low. It is especially suitable for spraying construction of ready-mixed concrete for long-term and long-distance transportation.

The invention belongs to the technical field of water-based paint, and discloses a preparation method of water-based colorful paint. The method is to add various color pastes into the white base paint B solution containing titanium dioxide to obtain a colored base paint, add the colored base paint to the transparent dispersed phase C and stir evenly to obtain a dispersed phase of the colored paint, and add the dispersed phase of the colored paint to the protective glue A The finished water-based colorful paint is obtained by granulating in the solution; wherein, the mass fraction of titanium dioxide in the white base paint B is within 10%, and the mass fraction of the color paste in the color base paint is not more than 20%. The viscosities of the dispersed phases of the basic paints of various colors prepared by the method are basically the same, and the particle size of the granulation is controllable, which creates conditions for the stability between batches during mass production in the workshop.
