Description
Technical field
The present invention relates to a kind of additive and addition means thereof that is used for the firework medicament granulation process, belong to the fireworks and firecrackers field.
Background technology
Firer, firework medicament in order to improve the free-running property of medicament, reduce the dust in sieve medicine, the powder charge process, and realize the accurate filling of medicament in process of production, need carry out granulation to medicament.Along with the reach of science, chemical deposition, water suspension method, electromagnetism sputtering method and high speed dispersion medical method etc. have been researched and developed.The firework medicament granulation process is general to mix medicament stock earlier, and then with binding agent raw material is bonded to particulate state.But meanwhile, contain aluminium powder in the firework medicament, flammable and explosive substances such as aluminium-magnesium alloy powder, especially in the granulation process, meeting and binding agent solvent generation chemical reactions such as water or alcohol, emit heat, cause the rising of pyrotechnics composition temperature and the consumption of aluminium powder and magnesium aluminum-alloy powder, go up appreciable heat and chemical phenomenon and produce macroscopic view, promptly formed chemical energy, i.e. heating, when the chemical reaction liberated heat exceeds the heat that firework medicament distributes gradually, heat can slowly be gathered, temperature raises gradually thereupon, chemical reaction is sharply accelerated thereupon, and temperature also sharply rises, thereby makes it at certain in a flash, reach the spontaneous ignition temperature of medicament, cause the combustion explosion accident.And some binding agent participates in the medicament reaction, has changed the oxygen balance value of former medicament, has had a strong impact on the physical and chemical performance of firework medicament.Therefore, select the additive of the gentle cohesive action of suitable landing, the generation of blast accident is avoided in the temperature rise of strict control medicament, keeps powder performance stable, is the important step of firework medicament granulation process.
Summary of the invention
The objective of the invention is in the firework medicament granulation process because of thermal accumlation causes blast accident, and keep the stable of powder performance, provide additive that has been used for the cooling effect and the binding agent that is complementary with it, with the security of raising granulation process.
The objective of the invention is to be achieved through the following technical solutions:
A kind of additive that is used for the firework medicament granulation process of the present invention, this additive are potassium bichromate and ripe sticky rice flour; Wherein, the quality of potassium bichromate accounts for 1%～3% of firework medicament total mass, and particle diameter is less than 80 orders; Ripe sticky rice flour is as binding agent, and the quality of ripe sticky rice flour accounts for 1%～4% of firework medicament total mass.
A kind of addition means that is used for the additive of firework medicament granulation process of the present invention, its concrete grammar is:
Adding accounts for medicament total mass 1%～3%, particle diameter less than 80 purpose potassium bichromate when medicament stock mixes, and is mixed to evenly;
In the bonding process, binding agent is replaced with the ripe sticky rice flour that accounts for medicament total mass 1%～4%, and to be made into massfraction be 3%～8% the aqueous solution.
Beneficial effect:
Additive cost of the present invention is low, consumption is few, adding technology is simple, solved the thermal accumlation problem of firework medicament in granulation process, medicament temperature and envrionment temperature are consistent, avoid causing blast accident, and additive does not influence the performance of setting off of former reagent combination.
