As a Nitrocellulose Manufacturer, share with you.
Nitrocellulose, also known as nitrocellulose, cotton body cotton colloid, etc., is a nitrate ester, white or slightly yellow cotton flocculent, soluble in acetone. It is the product of cellulose and nitrate reaction. H Nitrocellulose is obtained by reacting refined cotton with concentrated nitric acid and concentrated sulfuric acid. Nitrocellulose has two major application fields: military and civilian. The military component is mainly concentrated in the production of weapons, explosives and military products. The civilian part is used in various fields such as coatings, celluloids, man-made fibers, motion picture film inks, and cosmetics.
Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak bases, and various oils. Insoluble in water, soluble in acetone, ether and ethanol. It is easy to change color under sunlight, extremely flammable, smokeless, and emits a lot of gas instantly. Different degrees of polymerization have different strengths, but they are all thermoplastics. It discolors easily in the sun and burns easily. Pay attention to safety in production, processing, packaging, storage, transportation, and use.
Invasion route: inhalation.
Health hazard: Nitrocellulose itself is basically harmless to health.
Hazardous properties: Spontaneous combustion when exposed to air. It is easy to burn and explode in case of open flame and high heat. It can react strongly with oxidants and most organic amines, causing combustion or explosion. Usually add ethanol, acetone or water as wetting agent. After the wetting agent is dried, it is easy to cause fire.
Combustion (decomposition) products: carbon monoxide, carbon dioxide, nitrogen oxides.
Spill emergency treatment
First, emergency response to leakage.
Isolate the leaking contaminated area, set warning signs around it, and cut off the source of fire. It is recommended that emergency handlers wear gas masks and appropriate work clothes. Collect them in closed containers with spark-free tools and mark them for disposal or incineration on site if safe. If there is a large amount of leakage, collect and recycle or dispose of it after harmless treatment.
Second, protective measures.
Respiratory protection: When the concentration in the air is high, wear a dust mask.
Eye protection: Wear safety glasses.
Protective clothing: Wear work clothes.
Hand protection: Wear protective gloves if necessary.
Others: Smoking, eating and drinking are not allowed on the job site. After work, shower and change clothes. Pay attention to personal hygiene.
Third, first aid measures.
Skin contact: Rinse with running water.
Eye contact: Rinse with running water.
Inhalation: off the scene.
Fire fighting methods: mist water, carbon dioxide, foam, sand.
