Chemical formula: C24H36N8O38

Controlled category: Catalogue of Hazardous Chemicals (Explosive)

nature

Nitrocellulose is a white, odorless, and odorless solid. Celluloid plastic is a thermoplastic material containing 20% camphor plasticizer. It softens significantly at 80 ℃, can be molded and processed at 110-125 ℃, and can self ignite above 165 ℃. Transparent, soft, with high mechanical strength and low water absorption. No deformation and no white spots in boiling water for 2 minutes. Stable to water and general dilute acid solutions, can be corroded by dilute alkaline solution, partially soluble in benzene and dichloroethylene, and soluble in solvents such as ethanol and ethyl acetate.

Method of production

Nitrocellulose is a mixture of acid that nitrates cellulose, undergoes acid removal, pre washing, boiling, washing, dehydration, and then uses alcohol to remove water, resulting in nitrocellulose containing alcohol.

purpose

Nitrocellulose is mainly used in the plastic industry to manufacture stationery and educational items such as table tennis balls, triangular plates, pen holders, eyeglass frames, toys, and umbrella handles and tool handles in daily necessities. Nitrocellulose can also be used as a fiber, adhesive, coating, and substrate material.

Security

This product is non-toxic. This product belongs to Class A flammable dangerous goods. Packaged in wooden boxes with plastic bags lined inside. Each box should not exceed 160kg, or packaged according to user requirements. There should be a "flammable" mark on the outside of the box. Storage should be placed in a dry, ventilated, and clean warehouse, away from heat sources and direct sunlight. It should not be stored together with acidic, self igniting, and explosive materials. It is strictly prohibited to approach open flames. Transportation should be protected from sunlight and rain, and should be carried out in accordance with the transportation regulations of the transportation department for dangerous goods.

Forming processing

CN is fully kneaded with plasticizers (such as camphor), solvents (alcohol), dyes (or pigments) in a kneading machine at 36 ℃, and then filtered in a pressure filter at 60 ℃. The filtered material is rolled on a two roller rolling machine, and the resulting thin sheet is crushed, dried, flattened, or polished to obtain sheet-like CN plastic. The rolled thin sheet can also be placed into an extrusion machine to form a tubular object.
