Nitrocellulose
Nitrocellulose, known as nitrocellulose, also known as nitrocellulose, nitrocellulose, usually by the lint fiber and wood pulp and other fiber materials immersed in concentrated nitric acid concentrated sulfuric acid mixture obtained in the majority of the preparation for the use of propellant The Compared with nitroglycerin, relatively stable, safe and easy to transport. ▪ In 1838, T · P · Peluz first discovered that cotton could be burned after dipping in nitric acid. ▪ In 1845, the German chemist C · F · Sheen worshiped cotton in a mixture of nitric acid and sulfuric acid, and then washed off the excess acid, thereby inventing nitrocellulose. ▪ In 1860, the Major of the Prussian Army, E 郐 Erz, made guns and bullets with nitrocellulose. ▪ Beiyang Machinery Bureau is the world's first manufacturer of nitrocellulose pyrotechnic. At present, the world's manufacturers of nitrocellulose are: BNC and Taiwan Tainan Group, the two companies recently in Nanjing Chemical Industry Park joint venture to build Nanjing in the nitrate Chemical Co., Ltd., after the completion of the factory can produce 15,000 tons per year of nitrocellulose coating. Nanjing Nitroon Chemical Co., Ltd. has not opened on the collapse of the current production of nitrocellulose manufacturers are: Sichuan North nitrocellulose Co., Ltd., the world's first, with an annual output of 47,000 tons to 52,000 tons.
