Several types of nitrocellulose

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 advantage of aqueous nitrocellulose

The analysis of the advantages and disadvantages of aqueous china nitrocellulose.

china Nitrocellulose Advantages: with water as the solvent, VOC (volatile organic compounds) content is low, fully able to meet the requirements of Europe and the United States on environmentally friendly water-based paint performance; performance, and has the characteristics of polyurethane and nitrocellulose (NC), at the bottom of the drying rate and wood material sealing performance, compared with the traditional water paint slow have certain advantage; is not easy to burn, storage and transportation convenient. Can accelerate the drying rate of film.
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 required to achieve environmental protection

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.

The most important point for the whole use of nitrification and cellulose is that it is in use. One is that it is a chemical product. If it is not good, it will have a great impact on its environment. There is also a need for the use of its products, which is more natural for the products.

But some manufacturers, it is in the production of all kinds of reasons, not so that the need for environmental protection, so users in their own use, but also to pay attention to the choice of the above problems, so for its products, it is to be able to make it on its own products to achieve high environmental protection.

So for the use of cellulose, the user should be very good attention, only for the user in the use, can make it up to a very high material requirements, in order to ensure that it is in the environmental protection requirements, of course, relative to some of the material, it will make it in their own price decline, so generally not environmentally friendly products, it is often a low price performance, there is one aspect, is it in the production process of the above requirements.

For storage conditions of the nitrocellulose

Nitrocellulose is a kind of chemical substances, in the daily use of life need to pay attention to a lot of things, in the process of transportation need to be treated with caution, so when you need to pay attention to what the problem of the transport of fiber?

Storage and transportation conditions: stored in a cool, ventilated warehouse, storage temperature should not be over 30 degrees, away from the fire and heat. Isolation and storage of organic amines and oxidizing agents. Storage and transportation must be advanced first out, the damage to the packaging to be repaired in time. Should always check the wetting agent dry conditions, when necessary to increase the wetting agent. In order to make wet uniform distribution can be in after a certain time of storage (e.g., 5 months) will be packing upside down (reagent exception), after a period of time to adjust. Handling should be handled with care, packaging to prevent breakage.

Handling and storage of the nitrocellulose

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, namely 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.

Nitrocellulose is a flammable dangerous goods warehouse, need good ventilation, the temperature should not exceed 35 degrees, humidity of not less than 50 degrees. Must be stored separately, the facility must be explosion-proof, the warehouse is best surrounded with explosion-proof.

What are the dangers of nitrocellulose

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.

Measures for preventing and treating the leakage of nitrocellulose

Nitrocellulose is a kind of dangerous chemical substances, in daily life is also a wide range of applications, in the daily life to remember to properly handle the cellulose, to prevent leakage. So what should we do when we have a spill?

Respiratory system protection: when the air concentration is high, wear a dust mask.

Eye protection: wear safety glasses.

Protective clothing: wear overalls.

Hand protection: wear protective gloves when necessary.

Other: smoking, eating and drinking water. After work, shower and change clothes. Pay attention to personal hygiene.
