Dry ice is solid carbon dioxide with a temperature of -78.5°C. When it is heated and turns into a gas, it condenses the water vapor in the nearby air into countless small water points, which is white mist. If you pour hot water on dry ice, the white mist will be very thick, like a fairyland. This method is often used to create fairyland on the stage. Industrial applications of dry ice: penicillin manufacturing, preservation of fish, cream, cheese, sorbet, etc., low-temperature transportation, fire extinguishing agent, coolant, etc. Dry ice is suitable for bioengineering, fish product processing, machinery manufacturing, electronic industry, beverage beer, environmental protection, greenhouse, stage effects, food preservation, on-site cooling, bread, refrigerated transportation, fire extinguishing, machinery manufacturing (casting/welding), disinfection, Neutralizing alkaline, tobacco puffing, steelmaking, plastic blow molding, water treatment, cleaning and other industries.
