Method. Ice blasting is a method of industrial cleaning that uses a continuous supply of compressed air to accelerate suspended ice particles to high speeds. The ice particles are ejected from a nozzle toward the surface to be cleaned. The ice particles impact the contaminant covering the surface, breaking it apart and knocking it off.
Dry-ice blasting is an efficient [1] [verification needed] cleaning method. Dry ice is made of reclaimed carbon dioxide that is produced from other industrial processes, and is an approved media by the EPA, FDA and USDA. It also reduces or eliminates employee exposure to the use of chemical cleaning agents.
Flake ice is a loose definition of a group of ice types with irregular particle sizes. These types can be roughly grouped into two main types: scale ice and granular ice. This can cause confusion as different manufacturers, industries or even geographical areas will say flake ice and mean different things.
Ice blasting is the use of explosives to break up ice in rivers, aiding navigation and preventing flooding. This is done during the spring when snow is melting and river ice is breaking up. There is always a chance that the ice flows could collide creating an ice jam and blocking the river. The river, filled with melt water, will quickly flood ...
Phases of ice. Log-lin pressure-temperature phase diagram of water. The Roman numerals correspond to some ice phases listed below. The phases of ice are all possible states of matter for water as a solid. Variations in pressure and temperature give rise to different phases, which have varying properties and molecular geometries.
Carbon dioxide cleaning ( CO2 cleaning) comprises a family of methods for parts cleaning and sterilization, using carbon dioxide in its various phases. [1] Due to being non-destructive, non-abrasive, and residue-free, it is often preferred for use on delicate surfaces. [2] [3] [4] : 275 CO 2 cleaning has found application in the aerospace ...
Laser ablation of an asteroid-like sample. Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates.
Thermal transmittance. Thermal transmittance is the rate of transfer of heat through matter. The thermal transmittance of a material (such as insulation or concrete) or an assembly (such as a wall or window) is expressed as a U-value. The thermal insulance of a structure is the reciprocal of its thermal transmittance.
