Product characteristics
(A) H-type characteristics
hard film formed;
solvent than the "L"-type volatile faster;
easy to be alcohol, aromatic and aliphatic solvents dilution;
more excellent mechanical properties.
more likely to be due to H-ester solvent, it is also known as ester soluble nitrocellulose.
(B) L-type characteristics
forming a thermoplastic film;
can be a lot of alcohol (especially methanol and ethanol) dissolved;
easy to be aromatic solvent dilution;
special requirements formula to solve the problem, for a lot of paint thinner, alcohol, low odor paint (printing inks), gel dip coating and sealing of the coatings.
L-easy because alcohol dissolves, it is also known as alcohol-soluble nitrocellulose.
Third, the name (for example)
Floc tablet nitrification (the nitrocellulose sheet) cotton named
Type + + viscosity of RCC abbreviation abbreviation specifications + wetting agent
Be expressed on a high-nitrogen flake 1 / 2 seconds of alcohol (floc) nitrocellulose.
Fourth, product packaging
Fair share of packaging and packaging product packaging.
uniform application of pressure within the packaging of high density polyethylene blown film for anti-static bags;
outside the bag packaging paper bag (that is, composite plastic woven bags), corrugated boxes, composite drum and steel drum.
V. Product Technology Security Manual (MSDS)
See MSDS folder.
VI, the product uses
Widely used in wood coatings, metal coatings, inks, paper coatings, leather coatings, nail polish, such as incandescent and celluloid.
VII, product use and storage
(A) transport measures:
Nitrocellulose transit must be extremely careful when loading and unloading to take measures to prevent collision; if transport pallets, the pallets of goods to use the appropriate tape or film wrapped around a solid, the composite paper should pay attention to sharp hard objects that can not be cut, packaged to avoid any form of nitrocellulose (eg, sliding) friction.
Bottled nitrocellulose on a dedicated truck should be used, such as the rim along the diagonal of the barrel roll, it should be spent on the floor mat anti-slip rubber skin fire.
(Ii) the use of preventive measures:
1, the site operator should wear flame-retardant anti-static clothing;
2, and the solution was soiled work clothes NC is the source of serious fires, in the event of a clean work clothes should be replaced immediately;
3, on-site storage of nitrocellulose duty should not exceed the number of the number needed for the production, packaging should be used nitrocellulose to open, to prevent the nitrocellulose kill;
4, the production site is strictly prohibited fireworks, to avoid any due to friction, impact the process may produce sparks;
5, can only use bronze or other non-ferrous metal tools to open the metal lid dress nitrocellulose;
6 out before dumping the nitrocellulose should be packed in polyethylene bags lined the upper and anti-roll sets out the upper edge of the packaging and carefully empty the nitrocellulose, clear bags should be completed within the NC's back into the sealed packaging, to packaging specialist cleaning up the site to clean up the nitrocellulose.
(C) Fire
1, water is the most effective fire extinguishing agent, must ensure that sufficient water;
2, the combustion rate of nitrocellulose containing alcohol and alcohol itself is fairly, and lacquer film faster burning rate;
3, it is recommended to install an automatic rain in the Treasury system;
4, steel drums nitrocellulose fire, the barrel will have a greater pressure to open the lid red, burning nitrocellulose will fly ten meters away, the fire should be at a safe distance outside of work;
5, nitrocellulose combustion will produce large amounts of nitrogen dioxide and carbon monoxide poisonous gas, a good site should wear protective equipment and protective clothing
Use:
Widely used in wood dope, metal dope, oil print, paper dope, leather dope and others.
