Dry ice refers to solid carbon dioxide, which is a white solid shaped like ice and snow, and vaporizes directly without melting when heated, hence the name dry ice. Sublimation occurs at -78.5 ℃, absorbing heat and sublimating into carbon dioxide gas. It has no residue, is non-toxic, has no odor, and has a sterilizing effect.
1. Easy to use: Suitable for e-commerce to keep frozen items cold during transportation.
2. Low temperature: The temperature of dry ice is minus 78.5 ℃.
3. Environmentally friendly, clean and pollution-free: Dry ice continuously evaporates into gaseous carbon dioxide, which not only does not cause pollution to food, but also serves as an oxygen barrier and anti-corrosion agent.
4. Convenient transportation: Compared to other refrigerants with the same energy, dry ice transportation is more convenient.
5. Low cost: Compared to other refrigerants, dry ice has a lower production cost.
Wide applicability: Dry ice has a very wide range of functions, covering multiple fields such as cold chain transportation, medical, chemical, industrial cleaning, food, stage effects, etc.
