spray-up techniques
1Spray drying — is a commonly used method of drying a liquid feed through a hot gas. Typically, this hot gas is air but sensitive materials such as pharmaceuticals, and solvents like ethanol require oxygen free drying and nitrogen gas is used instead. The liquid …
2Spray forming — Spray forming, also known as spray casting, spray deposition[1] and in situ compaction,[2] is a method of casting near net shape metal components with homogeneous microstructures via the deposition of semi solid sprayed droplets onto a shaped… …
3Spray and pray — is a derisive term for firing an automatic firearm towards an enemy in long bursts, without aiming. This may be done especially by the poorly trained. It differs from suppressive fire as the shooting is sloppily directed. This term does not apply …
4Spray-on skin — is a patented skin culturing treatment for burns victims, developed by plastic surgeon Dr Fiona Wood of Perth, Western Australia.Dr Wood s treatment is under ongoing development. Where previous techniques of skin culturing required 21 days to… …
5List of coating techniques — This list contains an overview of coating techniques for thin film deposition, found in the field of materials science. The techniques can be classified as follows: Chemical vapor deposition (CVD) * Metalorganic vapour phase epitaxy *… …
6Pepper spray — This article is about the chemical compound. For agent used in riot control, see Pepper spray projectile. This article forms part of the series Chemical agents Lethal agents Blood agents Cyanogen chloride (CK) …
7Cyclonic spray scrubber — Figure 1 Irrigated cyclone scrubber Cyclonic spray scrubbers are an air pollution control technology. They use the features of both the dry cyclone and the spray chamber to remove pollutants from gas streams. Generally, the inlet gas enters the… …
8Anti-frogman techniques — are security methods developed to protect watercraft, ports and installations, and other sensitive resources both in or nearby vulnerable waterways from potential threats or intrusions by frogmen or other divers.Risks and threats to be defended… …
9Gas dynamic cold spray — is a coating deposition method developed in the mid 1980s in the Soviet Union in The Institute of Theoretical and Applied Mechanics by Papyrin and his team. The solid powders (1 to 50 micrometers in diameter) are accelerated in supersonic gas… …
10Baffle spray scrubber — Baffle spray scrubbers are a technology for air pollution control. They are very similar to spray towers in design and operation. However, in addition to using the energy provided by the spray nozzles, baffles are added to allow the gas stream to …
