Nitrocellulose is widely used as support in diagnostic tests where antigen-antibody binding occurs; e.g., pregnancy tests, U-albumin tests, and CRP tests. Glycine and chloride ions make protein transfer more efficient. Radon tests for alpha track etches use nitrocellulose. Adolph Noé developed a method of peeling coal balls using ...
Nitrocellulose, dry or wetted with less than 25 percent water (or alcohol), by mass UN 0341: 1.1D: Nitrocellulose, unmodified or plasticized with less than 18 percent plasticizing substance, by mass UN 0342: 1.3C: Nitrocellulose, wetted with not less than 25 percent alcohol, by mass UN 0343: 1.3C
The United States military replaced black powder during the first decade of the 20th century with smokeless powders formulated from nitrocellulose colloided with ether and alcohol. [2] Large quantities were manufactured for World War I and significant amounts remained unused after the war. Nitrocellulose deteriorates in storage, but military ...
Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
For instance, power grades of black powder, unsuitable for use in firearms but adequate for blasting rock in quarrying operations, are called blasting powder rather than gunpowder with standard proportions of 70% nitrate, 14% charcoal, and 16% sulfur; blasting powder may be made with the cheaper sodium nitrate substituted for potassium nitrate ...
Poudre B" is made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% paraffin. "Poudre B" is made up of very small paper-thin flakes that are not white but dark greenish grey in colour. "Poudre B" was first used to load the 8mm Lebel cartridges issued in 1886 for the Lebel rifle.
The lacquer grade of soluble nitrocellulose is closely related to the more highly nitrated form which is used to make explosives. They become relatively non-toxic after approximately a month since, at this point, the lacquer has evaporated most of the solvents used in its production.
[3]: 287–289 Nitrocellulose produces greater volumes of gas per volume of solid than black powder does, so nitrocellulose bulk powders were less dense than later smokeless powders. Nitrocellulose bulk powders designed for early straight-sided black powder rifle cartridges like the .32-40 and .38-55 were friable and easily crumbled. The ...
