Other names: DTsD, DTsDA, N-TsIANOGUANIDIN, DITsITsIANOGUANIDIN Formula: C2P4N4 Group: industrial chemistry Look: colourless crystals Supplier: LLC Company Plazma ® Packaging: bag of 25 kg Producer: China, Germany, France Dicyanodiamide represents flavourless colourless crystals with specific bitterish smack, is well dissolved in warm ether and especially in hot water, restrictedly we will dissolve in cold water, relatively we will dissolve in alcohol and liquid ammonia, is not soluble in benzene and cold ether. On chemical to properties it is similar to cyanamide. Melting temperature - 209 °C, density - 1,405 g/cm ³. Contain in drain waters of productions of plastic, glues, melamine, pharmaceutical productions.
Receive from calcium cyanamide under the influence of acetic acid or dimerization of cyanamide at its heating to melting temperature. Dicyanodiamide is of very great interest as the hidden hardener allowing to create high-strength one-component epoxy adhesives with long term of storage.
It is applied as hardener of "hot" hardening of epoxies by production of plasts, dicyanodiamide of oformaldegidny pitches, varnishes, fabrics, cyanic connections, hydrazine salts.
It is used in production of biofireproof fiber boards for impregnation of tree in the fire-prevention purposes.
Is initial product by production of melanin, guanidine, sulfanamide preparations, epoxies, synthetic dubitel (syntans), explosive substances (nitroguanidines), and also some pharmaceuticals, for example, of luminal. Safety requirements.
Ditsiandnamid - malotoksichen. On extent of impact on organism belongs to the 3rd class of danger.
Danger of sharp poisoning at hit in stomach and at inhalation is insignificant.
At continuous contact with dicyanodiamide dryness, peeling and ulceration of skin, especially pleated, itch, dryness in throat and hoarse voice is observed. At hit in eyes - pain and gripes.
Maximum allowable concentration of dicyanodiamide in air of working zone - 0,5 mg/m ³ that corresponds to maximum allowable concentration of free cyanamide - the most toxic substance of this class of connections.
Ditsiandnamid - slow-burning substance. When heating higher than temperature of melting ditsiandnamid decays with release of ammonia.
The dust weighed in air with humidity of 0,1%, ash content of 0,3%, the fraction of 850 microns containing 1% of particles of 74 microns in size. has lower limit of vzryvayemosga of 176 r/m ³, self-ignition temperature of 845 °C. The accumulated dust is flammable.
At fire emergence suppression should be made sprayed water with "smachivatel", foam. At volume suppression it is impossible to use compact water jets as streams can cause formation of explosive concentration of dust.
It is necessary to apply gas fire extinguishing structures and high-multiple foam.
At hit of dicyanodiamide on skin it should be washed away water, and at hit in eyes - to wash out water and to see doctor.
During the works connected with dicyanodiamide dust it is necessary to apply the filtering respirator, overalls (suit cotton, boots, gloves) and safety spectacles. Besides, it is necessary to carry out preventive greasing of skin of hands by protective paste or ointment.
All production rooms in which works with dicyanodiamide are carried out have to be equipped with supply and exhaust ventilation, places of the greatest dusting - local exhaust ventilation.
Packaging, transportation and storage.
Technical dicyanodiamide is packed into the four-layer open paper bituminized bags with not impregnated inner layer of paper or three-four-layer open paper bags with insert from polyethylene film, or by the four-five-layer laminated bags (the inner layer is laminated), or the five-layer paper combined bags with two layers from the bag bituminized paper. Net weight is 25-35 kg.
The technical dicyanodiamide packed into bags is transported railway, motor and river transport in the covered vehicles according to the rules of transportation of dangerous loads existing on transport of this look.
Specialized soft containers with ditsnandiamidy, and also transport the packages fastened with thermoshrink film in the covered and open rolling stock and motor transport according to the rules of transportation of dangerous loads existing on transport of this look.
It is allowed to transport dicyanodiamide the opened motor transport with shelter of product bed curtains.
Technical ditsiandnamid it has to be stored in the closed warehouse.
Warranty period of storage - one year from the date of production.
LLC Company Plazma ® carries out deliveries of chemical products from warehouse in Kharkiv in terms and for reasonable prices, on conditions, favorable to you.
