Nitrocellulose plasticizer
Nitrocellulose, also known as cellulose nitrate, is called NC, commonly known as nitrocellulose, which is the product of cellulose and nitric acid esterification. Using cotton fiber as raw material of cellulose nitrate called nitrocellulose. Nitrocellulose is a white fibrous polymer, water resistance, dilute acid resistance, weak alkali resistance and various oils. The degree of polymerization is different, and its strength is different, but all of them are thermoplastic. Nitrocellulose is easily discoloration in the sun and is very easy to burn. Attention should be paid to safety in the production, processing, packing, storage, transportation, sales and use.
Nitrocellulose plasticizer is a common industrial product. With the development of society, nitrocellulose plasticizer is widely used in various fields.
Cellulose nitrate in 1832 by the French H. cloth Lakongnuo with concentrated nitric acid and wood or cotton effect produced. In 1846 C.F. Schoen gabain with nitric acid and sulfuric acid - produced cellulose nitrate, and its performance was studied. It was found to be 2~3 times more powerful than black powder and could be used for military purposes. At that time, only explosives were used, because it burned too fast, the stability problem was not solved, and the explosion accidents were frequent. With the appearance of cotton is similar to maintain a nitrocellulose, fiber structure obviously. Then the paper industry for cutting machine will be chopped, after drying to obtain white powder nitrocellulose, was still only as blasting treatment.
In 1869, J.W. special hayer certain polymerization degree of cellulose nitrate and camphor added alcohol, made of celluloid.
In 1873, Nobel in an experiment when cut his hand, he picked up the nitrogen content of low cellulose nitrate deposited over the wound, a bold idea emerged: mixed with nitroglycerin. He immediately, a collodion dissolved in nine copies in nitroglycerine. Through this experiment, he got a strong explosive glue - gumming.
Alcohol ether solvent and compacted by cellulose nitrate in 1884 the French chemist P. Weiaiye, single base propellant was prepared to slow burning. From then on, nitrocellulose has become the main raw material for the production of various kinds of gunpowder, and has been produced and applied in a large amount. Without solvent plasticization and molding of cellulose nitrate is high explosive category, not as a result, it is the application of gunpowder, the explosion of high explosive change characteristics. But because of the source of raw materials and economic reasons, no nitrocellulose is used almost as an explosive drug, but it is mainly used in the manufacture of gunpowder.
When Bienie Dick, a French chemist, did the experiment, a flask dropped on the ground and was not broken. He was curious and couldn't find the answer for a moment. He put the label on the flask, marked the problem, and saved it. One day, he came across the report that two bus drivers and passengers were scratched by windshield fragments. He immediately associates with the flask. After examination, it was found that the flask had once been over the cellulose nitrate solution. After evaporation, the solution left a layer of colorless and transparent film, and it adhered to the bottle wall firmly and played a protective role. The glass fiber was invented.

Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
According to the structure of cellulose, only three nitrate groups can be introduced at most each ring. How much nitrates are introduced determines the properties and uses of nitrocellulose. The method of characterization is usually using the nitrogen content and the viscosity representing the degree of polymerization. The nitrogen content of more than 13% is called a strong cotton, can be used in the manufacture of gunpowder; the nitrogen content of 12.6% is called the collodion, used in the manufacture of rubber explosive (i.e. cellulose nitrate dissolved in nitroglycerine and the formation of colloid) and the mitre (see industrial explosives); nitrogen content is 8% ~ 12% called weak cotton. Can be used in the manufacture of the film (see support), celluloid and nitro varnish etc.. China is classified by the number of NOx gases released by the complete decomposition of nitrocellulose per gram.
The nitrocellulose membrane is also called the NC film, which is often added with a nitrocellulose plasticizer. In colloidal gold paper, it is used as the carrier of the C/T line, and it is also the place of the immune response. So the NC film is the most important material in the experiment.

The nitrocellulose membrane is also known as the NC film, with carrier do C/T line in the colloidal gold strip, but also the immune reaction took place, so the NC film became the most important test of supplies, but because it belongs to non standard devices, basically the beginning of each project stage will encounter how to choose NC film right problem. At the same time, there is a discussion about whether the NC film should be treated later and how to deal with it.
The process of the NC film is very similar to that of the ordinary papermaking process, and we can draw on the understanding of the paper.
The purchase of raw materials to the cellulose nitrate particle is a very common organic compound, being dissolved in the mixed slurry, paste, nature will add a certain proportion of the reagent to adjust the final form of the film, is generally a reagent formula, including surfactant / polymer / polymer / salt forming agent dissolved in a buffer system.
