Single-component coatings dry physically, purely through vaporisation of the solvent mixture. |
The cloud moves at wind speed and after complete vaporisation the gas becomes lighter than air and disperses. |
Adding water to these two systems creates vaporisation which is thought to increase the availability of odour from sub-surface targets. |
It can be calculated for example from a substance's boiling point, heat of vaporisation, refractive index and molar volume. |
With the assumption of quasisteady vaporisation, the mass flaw rate is constant, independent of radius. |
Air is converted to a gas with a temperature of about 4000° C. It is enriched with combustion and vaporisation residue from copper, steel and cast resin. |
