  • Publication number: 20210283442
    Abstract: A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.

    Abstract: A carbon-based porous material microscopically exhibiting a three-dimension 1 cross-linked net-like hierarchical pore structure, a specific surface area of 500˜2,500 m2/g and a water contact angle greater than 90°. The surface of the carbon-based porous material has a through hierarchical pore structure with mesopores nested in macropores and micropores nested in mesopores, the content of mesopores is high, and there are more adsorption activity sites exposed on the surface of the material, so that the diffusion path for organic gas molecules in the adsorption process is shortened. At the same time, the absorption and desorption rates may also be accelerated and the desorption temperature may be lowered. Furthermore, benefits result for solving the desorption and recovery problems of organic gas molecules. Moreover, the defects of ordinary porous carbon materials being easily hygroscopic, having a weakened capacity to adsorb target gas molecules in a humid environment, etc. are further effectively solved.
