Re: dust off danger
You just proved MY point.. silly man.... R2 is a liquid COOLANT, which forces the gas to CONDENSE.. thus! POOF!! CONDENSED GAS!! WOW.. so difficult. Thanks, took Chemistry 101, got a 4.0, so if I were you, you may want to back down ASAP. You are not going to win this argument AT ALL.
R2 and R1 are both related to Freon12, which is used in refrigerators and the like. Thusly, it is right to assume R2 is COLD. Also, when a gas decompresses, it WARMS UP. Have you ever watched the process of makign liquid nitrogen?? They SUPER COMPRESS nitrogen gas until it becomes a LIQUID.... a SUPER COOLED liquid. Now, in this case, because CANS are not well insultated, they cannot just put compressed liquid gas into the container. So they put in R2, which is a gaseous substance that has very LOW LONDON DISPERSION FORCES, thus, it doesnt break back into a gas as easily as say.. liquid nitrogen. Now, taking into account that the GAS they use in dustoff is really just a mediocre mix of carbon dioxide and nitrogen and oxygen and hydrogen, that means.. oh guess what............ THEY DO NOT COMPRESS THOSE TO LIQUID STATE!!! Do you realize that if Liquid nitrogen was present, the CO2 would solidify into dry ice IMMEDIATELY??? Ok, so please think this through.
