A heat gun is a device used to emit a stream of hot air. They are superficially similar in shape and construction to a hair dryer, though they run at much higher temperatures. A blowdryer or hairdryer is an Electromechanical device designed to blow cool or hot Air over wet or damp Hair, in order to accelerate the They are often found in physics, materials science, chemistry, engineering, and other types of laboratory or shop settings. Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Materials Science or Materials Engineering is an interdisciplinary field involving the properties of matter and its applications to various areas of Science and Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties Engineering is the Discipline and Profession of applying technical and scientific Knowledge and
Heat guns can be used to dry and strip paint, apply heat shrink tubing, dry out damp wood, bend and weld plastic, soften adhesives, and thaw frozen pipes. Paint is any Liquid, liquifiable or mastic composition which after application to a substrate in a thin layer is converted to an opaque Solid Heat shrink tubing (or commonly "heat shrink" is a tube which shrinks in diameter when heated Wood is hard fibrous lignified structural tissue produced as secondary Xylem in the stems of Woody plants notably trees but also shrubs Plastic is the general common term for a wide range of synthetic or semisynthetic organic solid materials suitable for the manufacture of industrial products Glue or adhesive is a compound that adheres or bonds two items together They are also used in electronics to desolder circuit board components. Electronics refers to the flow of charge (moving Electrons through Nonmetal conductors (mainly Semiconductors, whereas electrical In Electronics, desoldering is the removal of Solder and components from a circuit for Troubleshooting, repair purposes and to salvage components They typically output air at temperatures ranging from 100-550°C (200-1000°F) with some hotter models running around 760°C (1400°F). The Celsius Temperature scale was previously known as the centigrade scale. Fahrenheit is a temperature scale named after Daniel Gabriel Fahrenheit (1686–1736 a German Physicist who proposed it in 1724
Some have a rest, so they can be activated and placed on a workbench, which frees the operator's hand. Heat guns can have nozzles which deflect their air for various purposes, such as concentrating the heat on one area, or thawing a pipe without heating up the wall behind.
