minus-squareThorry@feddit.orglinkfedilinkarrow-up3·24 days agoReally? I think air duster is usually just pure CO2 (the ones without HFC at least)
minus-squarelemming741@lemmy.worldlinkfedilinkEnglisharrow-up3·24 days agoCO2 is 750+ psi at room temperature. A pressed sheet steel can is typically less than 100psi. If you don’t use a liquid propellant, the pressure will drop a lot as you use it. The effect is worse the fuller the can is. https://www.justrite.com/understanding-aerosol-propellants https://science.howstuffworks.com/innovation/everyday-innovations/aerosol-can3.htm
minus-squareThorry@feddit.orglinkfedilinkarrow-up1·edit-224 days agoIt’s compressed CO2, not liquid CO2. They marketed is as a non flammable non HFC air duster which you can hold upside down, often with something like 360 or something in the name. Since it’s just compressed gas, it doesn’t spray a liquid like the HFC ones do.
