Application of nitrocellulose
Nitrocellulose, also known as cellulose nitrate or nitrocellulose, is an organic polymer compound with the chemical formula (C6H7N3O11) n. It is the product of the esterification reaction between cellulose and nitrate, usually in the form of white or slightly yellow cotton fluff, insoluble in water, but soluble in organic solvents such as esters and acetone
Nitrocellulose, also known as cellulose nitrate ester, abbreviated as NC, commonly known as nitrocellulose, is the product of the reaction between cellulose and nitrate. Nitrocellulose made from cotton fibers is called nitrocellulose. Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis, and various oils. Different degrees of polymerization result in different strengths, but they are all thermoplastic substances. Easy to change color under sunlight and highly flammable. Attention should be paid to safety in production, processing, packaging, storage, transportation, sales, and use.
others nameï¼?Nitrocotton; Cotton body collodion; Low nitrogen nitrocellulose 1.Nitrocellulose, also known as nitrocellulose, cotton body collodion, etc., is a nitrate ester, white or slightly yellow cotton wool, soluble in acetone. It is the product of esterification of cellulose and nitric acid. Cellulose nitrate is produced by esterifying refined cotton with concentrated nitric acid and concentrated sulfuric acid. 2.Casï¼?9004-70-0 3. Appearance: White or yellowish cotton wool 4.useï¼?Nitrocellulose has two main applications, military and civilian. The military part mainly focuses on the production of weapons, explosives and explosives, and implements the management of military products. The civil part is used in paint, celluloid, artificial fiber, film ink, cosmetics and other fields. Cellulose nitrate is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis and various oils. Insoluble in water, soluble in acetone, ethyl ether ethanol mixture. Easy to change color under the sun, extremely flammable, smoke-free, instant release of a lot of gas. Different degrees of polymerization, its strength is also different, but are thermoplastic materials. It changes color easily in sunlight and burns easily. In the production and processing, packaging, storage and transportation, sales, use should pay attention to safety. Main use (1) High nitrogen content commonly known as fire cotton, used to make smokeless gunpowder; Low nitrogen content commonly known as collodion, used to manufacture spray paint, artificial leather, film, plastic and so on. (2) Used for making cultural and educational supplies, daily necessities, instrument signs, etc (3) Used in ink, leather, various nitrocellurocelluloses, rubber caps, typing wax paper, etc (4) For the production of cultural and educational supplies, daily necessities, instrument signs, etc., for ink, leather, various nitro paints, etc., for the pharmaceutical industry, photographic negatives, photographic negatives and leather manufacturing (5) celluloid, announced by the European Union on October 26, 2006, banned for the manufacture of toys.
