What are the uses of cellulose nitrate?
What are the uses of cellulose nitrate?
The principal use of cellulose nitrate is for the production of explosives, lacquers, and celluloid. The explosive applications are discussed below. In terms of lacquers, nitrocellulose dissolves readily in organic solvents, which upon evaporation leave a colorless, transparent, flexible film.
What is the uses of nitrocellulose in the production?
Nitrocellulose is used in explosives, rocket propellant, lacquer, flash paper, smokeless gunpowder, leather finishing, as a printing ink base, in coating bookbinding cloth, in laboratory testing films, in ping-pong balls, in pharmaceuticals and in celluloid used for early x-ray, photographic and movie film.
What is nitrocellulose coating?
Nitrocellulose coatings (NC) are single component physically drying solvent based wood coating. NC wood coating is generally preferred because of its ease of application, fast productivity and competitive pricing compared to other wood coatings.
Does nitrocellulose need oxygen burns?
Nitrocellulose has a low autoignition temperature, so keep it away from heat or flame (until you are ready to activate it). It does not require oxygen to burn, so once it ignites you cannot put out the fire with water.
What are the other names of nitrocellulose?
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid.
Does nitrocellulose dissolve in water?
Nitrocellulose, also known as cellulose nitrate, guncotton and NC, is the nitrate ester of cellulose….Nitrocellulose.

What is nitrocellulose made from?
nitrocellulose, also called cellulose nitrate, a mixture of nitric esters of cellulose, and a highly flammable compound that is the main ingredient of modern gunpowder and is also employed in certain lacquers and paints.
Is nitrocellulose the same as lacquer?
Nitrocellulose was adopted quickly by the car industry and remained the finish of choice through to the late-1950s. Furniture and musical instrument manufacturers also switched to nitrocellulose lacquer, and mostly it was referred to simply as ‘lacquer’.
How is nitrocellulose made?
Nitrocellulose is made by treating cellulose with a mixture of sulfuric and nitric acids. This changes the hydroxyl groups (–OH) in the cellulose to nitro groups (–NO3) as shown in Fig. 13.4. Nitrocellulose, also know as gun cotton and the main ingredient of smokeless gunpowder, decomposes explosively.
Is nitrocellulose soluble in water?
Nitrocellulose can be nitrated to various degrees….Nitrocellulose.

What is the difference between PVDF and nitrocellulose membranes?
The main difference between nitrocellulose and PVDF membrane is that nitrocellulose membrane has a higher protein-binding capacity whereas PVDF membrane has a comparatively low protein-binding capacity.
Where is nitrocellulose found?
In the commercial manufacture of nitrocellulose, wood pulp is the primary source of cellulose. Cellulose sheet and nitrating acids are fed into a reacting vessel, where nitration proceeds until the acids have been centrifuged from the nitrated product.
