(Translation: If you want to cover a larger wall or an entire room, it might be in your best interest to pick up a texture sprayer or hopper-style spray gun, which requires an air compressor.)
Plaster spraying allows a plasterer to skim a drywall more than five times faster than using a hand float to apply it. Although classic gypsum-based plaster can be sprayed if it is "spray grade," most plaster sprayers prefer the organic-based pre-mixed plaster packaged in a plastic bag because the plaster spraying machine does not need to be cleaned out after the job is finished, providing ...
Shotcrete. Shotcrete nozzle with 75 mm concrete hose from line pump and 20 mm compressed air line. Shotcrete, gunite ( / ˈɡʌnaɪt / ), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface. This construction technique was invented by Carl Akeley and first used in 1907.
The DP-27 is a light machine gun designed for the Soviet Red Army in the 1920s under the leadership of Vasily Degtyaryov (1880–1949), the first test model being the DP-26. Two test guns were manufactured and fired 5,000 rounds each from September 27–29, 1926, during which weaknesses were discovered in the extractor and firing pin mechanisms.
A corrosion pit on the outside wall of a pipeline at a coating defect before and after abrasive blasting. Sandblasting, sometimes known as abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove ...
Spray painting is a painting technique in which a device sprays coating material (paint, ink, varnish, etc.) through the air onto a surface. The most common types employ compressed gas—usually air —to atomize and direct the paint particles. Spray guns evolved from airbrushes, and the two are usually distinguished by their size and the size ...
Detonation spray coatings are applied using a detonation gun (D-gun) which is composed of a long-water-cooled metal barrel containing inlet valves for introducing gases and powders into the chamber. A preselected amount of the desired protective coating material known as feedstock (in powder form of particle size 5–60μm) is introduced into ...
The Gardner gun was an early type of mechanical machine gun. It had one, two or five barrels , was fed from a vertical magazine or hopper and was operated by a crank. When the crank was turned, a feed arm positioned a cartridge in the breech, the bolt closed and the weapon fired.
