WebbOther common forms of solid precipitation are: hail, sleet or ice pellets, graupel or soft hail or snow grains, and a special form: freezing rain, also known as glaze or rime. The latter falls as a liquid but freezes on contact with an object. When clear ice forms, freezing rain is called glaze. When the ice is milky, it is called rime. Webb1 jan. 2024 · The use of solid carbon dioxide (or dry ice) blasting has been developed as an established non-solvent, dry method for removing surface contaminants in a variety of cleaning applications. The basic principle is based on the impact of dry ice particles, propelled by a high pressure gas or a centrifugal accelerator, on the surface of the part.
