How much is dry ice? How much is a kilo?
According to the market price of June 5438 +2020 10, the dry ice is 3~6 yuan per catty.

Features: Carbon dioxide is invisible. Actually, it's not smoke (carbon dioxide), but fog (water). When carbon dioxide changes from solid to gas, it absorbs a lot of heat, which makes the temperature of the surrounding air drop rapidly. When the air temperature drops, its solubility in water vapor becomes smaller. Water vapor liquefies and releases heat, turning into small water droplets, that is, fog

This is the same as the "white fog" of popsicles in summer. It's all water droplets, not other gaseous substances. That is, we see white fog instead of white smoke. The temperature of dry ice is much lower than that of water, so it is equivalent to heating dry ice, which absorbs heat and sublimates, reducing the temperature of water and even freezing it.

Extended data:

Application scope: petrochemical power

Clean the main fan, air compressor, fume hood, steam turbine, blower and other equipment to remove coking and carbon deposition in various heating furnaces and reactors. Clean the PVC resin on the heat exchanger, and remove the oil, rust, hydrocarbons and surface dirt on various pressure vessels such as compressors, storage tanks and boilers;

Can clean electric boilers, condensers and various heat exchangers; Can directly clean indoor and outdoor transformers, insulators, distribution cabinets, live wires and cables;

Benefits of dry ice cleaning: effectively decompose pollutants to be cleaned; Because these pollutants are removed, the power loss is reduced; The maintenance cost of external equipment and its basic equipment is reduced; Improve the reliability of power system; Keep the insulator intact and non-abrasive clean; More suitable for preventive maintenance.
