Understanding Dry Ice
1. What is Dry Ice?
Dry ice is a common term for solid carbon dioxide (CO2), distinguishing it from regular ice. It's also referred to as smoke ice, CO2 ice, or smoke ice. Dry ice gets its name because it doesn't melt when heated; instead, it directly transforms into gas - a process known as sublimation.
Dry ice is used in various fields, including healthcare, processing and distributing food, hygiene and technical processes, stage effects, and special effects...
2. The Process of Creating Dry Ice: 3 Steps
Step 1: Dry ice is produced by compressing and cooling CO2 gas under high pressure to generate liquid CO2.
Step 2: The liquid CO2 is then expanded under low-pressure conditions, causing it to freeze into snow, which is compacted into convenient dry ice blocks, slices, or pellets.
Step 3: The density of the CO2 snow depends on the applied pressure and compression time. The density of the dry ice block can reach a maximum of 1.56g/cm3 at a temperature of -78.64 degrees Celsius.
Due to its extremely low temperature of -78 degrees Celsius, dry ice is commonly used as an alternative solution for refrigerating food and medical supplies. Additionally, pelletized dry ice is employed in the industrial cleaning sector.
3. Applications of Dry Ice in Daily Life
Dry ice finds extensive use in everyday life and business operations, encompassing several key applications as listed below:
- Preserving agricultural products at low temperatures/freezing
- Airfreight cargo transportation
- Creating smoke effects at weddings, on music stages, and in performances.
- Dry ice produces airborne mist near the ground. In this case, specialized fog machines are used to create dry ice.
- Creating layered mist effects for a cocktail tower
- Producing special effects for Halloween parties or haunted houses
Speaking of dry ice, we also have the concept of perpetual cold ice. So, what is Perpetual Cold Ice? Is it safe? Feel free to check out the article on thuthuat.tamienphi.vn for more information.
