Eye Contact
Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 measures
Keep eyelids open. Get medial attention.
Skin contact:
In case of contact, immediately flush skin with plenty of water. Cover the irritated skin with an emollient. Remove contaminated clothing and shoes. Wash cloth before reuse. Thoroughly clean shoes before reuse. Get medial attention.
Serious skin contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medial attention.
Nitrocellulose nitrocellulose: white or yellowish cottony, nitrocellulose could be dissolved in acetone. Name of cellulose nitrate, old nitrocellulose, nitrocellulose. NC is a polymer. Its molecular weight is very big. Its molecular formula is C6H7O2 (ONO2) a (OH) 3-an, where a is the degree of esterification, n is the degree of polymerization. The amount of nitrogen used to represent the degree of esterification.. Nitrocellulose is highly flammable and explosive, the risk degree according to the degree of nitration and containing nitrogen amount in more than 12.5% of nitrocellulose risk greatly. In case of fire, the burning. When the temperature exceeds 40, it can accelerate the decomposition and combustion. Containing nitrogen deficiency 12.5% of nitrocellulose, although more stable, but heated or stored for a long time, gradually decompose and release acid, reduce the ignition temperature, combustion blew.
Industry to NC points for No. 1 strong cotton (n is more than or equal to 13.13%), No. 2 cotton strong (nitrogen 11.9% to 12.4%) and 3 weak cotton (nitrogen 11.8% to 12.1%), burst collodion (containing nitrogen 11.94% to 12.3%), collodion (nitrogen containing 12.5% to 12.7%), varnish with cotton (including nitrogen 11.6% ~ 12.2%), celluloid cotton (containing nitrogen and 10.8% to 11.2%). In order to understand, and the literature of the nitrogen is less than or equal to 12.4% NC collodion, nitrogen >12.4% said pyroxylin.

The analysis of the advantages and disadvantages of aqueous china nitrocellulose.
china Nitrocellulose Disadvantages: as the first of the self emulsifying method of the synthesis of water-based resin, in the synthetic formula, application process and other aspects are not completely mature, some aspects of the performance and improve the space, to be further improved. The market offers recipes, PUD (waterborne polyurethane), styrene, acrylic based, how to import water nitrocellulose is a difficult problem.
Nitrocellulose is a chemical substance in environmental protection is more sensitive, so in nitrocotton production is completed is the need for identification of environmental protection, to meet the requirements of environmental protection can be put on the market.
Nitrocellulose is a chemical substance, the chemical point of view, it is very dangerous to the, then in daily life applications if the inappropriate application or operating will also produce dangerous results. Nitrocellulose (NC) is a kind of sensitive material, nitrocellulose risk size and nitrocellulose explosive power size has a proportional relationship, and the size of the explosive power of nitrocellulose and its nitrogen content has a very close relationship. Is generally believed that the nitrocellulose nitrogen content more, nitrocellulose, cellulose is degree of nitrification more and more thoroughly, nitrocellulose molecule is more lively, under the action of external force is easy to cause an explosion, explosion is also the power is bigger also. Nitrocellulose containing nitrogen, depending on the nitrification process, because in fact the nitrification process can as a increased with nitrogen.
