Dry Ice – Terms to Know
Dry ice is used in cooking and construction as a cleaner, an insecticide, a way to create fog or smoke as a theater special effect, and an element in school science experiments. It is usually sold in block form, but can also be purchased in pellets from grocery stores and other types of retailers. Here are a few important terms to know when shopping for dry ice.
CO2 – The chemical formula for carbon dioxide. In its solid form CO2 is called dry ice.
Liquid Nitrogen – A liquefied gas with a temperature of -321 Fahrenheit. It is used in many of the same applications as dry ice, but has a different chemical composition.
Liquid Hydrogen – Dry ice can be used to generate the fuel source liquid hydrogen from coal. As a fuel it is also cleaner than coal.
Sublimation – The process of going from a solid to a gas without passing through a liquid form. Sublimating a solid block of CO2 into CO2 gas by raising its temperature creates dry ice.
Dry Ice Blasting – A cleaning method in which dry ice is projected at high speeds to clean surfaces. Blasting is used to clean boats, construction materials, and buildings that have been damaged by fire.
Pelletizer – A pelletizer makes small nuggets, or pellets of dry ice that are used for blasting.
Block Press – A machine that creates blocks of dry ice weighing 50 pounds or more.
Reforming Press – A machine that takes scrap pieces of dry ice and reforms them into pellets.
