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
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 ...
In contrast, insoluble in alcohol, nitrocellulose was known as gun cotton and was used as an explosive. [13] [14] Nobel's patent refers to the production of Celluloid using camphor and soluble nitrocellulose; and this was taken to imply that Nobel was specifically distinguishing between the use of soluble and insoluble nitrocellulose. [14]
Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company [1]) is a form of nitrocellulose used in small arms cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants.
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 .
French war powder in 1879 used the ratio 75% saltpeter, 12.5% charcoal, 12.5% sulfur. English war powder in 1879 used the ratio 75% saltpeter, 15% charcoal, 10% sulfur. [114] The British Congreve rockets used 62.4% saltpeter, 23.2% charcoal and 14.4% sulfur, but the British Mark VII gunpowder was changed to 65% saltpeter, 20% charcoal and 15% ...
By 1936 improved DuPont process control produced batches conforming to published reloading data rather than requiring different charge specifications for each batch; [11] and those propellants have remained in production. Non-conforming batches were used to load commercial and military cartridges following traditional testing procedures.
Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this. Cellophane is also used in transparent pressure-sensitive tape, tubing, and many other similar applications.
