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.

Camphor is a colorless or white crystal, granular or fragile. It has an irritating aroma.Chemical Abstracts Agency nimber is 76-22-2, formula is C10H1O6, shiny, hot and toxic. For the center,the spleen has a dispersive analgesic effect, dehumidifies and kill insects, treat itching, pain and toothache. The camphor tree is extracted from the branches and steams, leaves roots and granular crystals of the camphor family plants. Camphor has the effects of through-hole, stagnation of qi, opening,dehumidify, insecticidal and antipruitic and analgestic, and treatment of itching, trauma, scabies and other toothache symptoms. The main ingredients is pure camphor,which is a camphor compound. Function The main function of camphor is: kill insects and stop itching, detumescence and pain, clear the orifes, benefit stagnant qi, and remove the filth. It is often used in solid wood furniture or wardrobe to prevent mildew and kill insects. Application 1. The role of the central nervous system Camphor have excited central nervous system 2. The effects on the cardiovascular system 3. The local action Camphor spread on the skin has a mild stimulation and corrosion protection. Hard hair red inunction. 4.
