Abstract
The invention discloses a method for filling firework-spraying compositions, which aims to provide a method capable of safely and efficiently filling firework-spraying compositions during manufacturing firework products of spraying decoration type, rotation type, rotation blastoff type and shelved firework type. The method comprises the following steps: adding water in firework compositions containing dextrin, or mixing volatile solvent with prepared firework compositions evenly to prepare liquid semiliquid; filling the semiliquid in a firework barrel; then, drying the compositions. When used in composition filling, the method does not require powder packing step compared with the prior firework composition-filling process, thereby improving production efficiency; moreover, the method effectively improves the status quo that explosion accidents occur frequently in composition filling and packing processes during firework manufacturing, thereby ensuring both personnel safety and property safety in a factory.
Description
Technical field
The present invention relates to safe, the loading method efficiently of the method for a kind of filling firework-spraying compositions in the fireworks industry, particularly a kind of firework-spraying compositions.
Background technology
In the fireworks industry, on October 25th, 2004, GB 10631-2004 " pyrotechnics firecracker safety and the quality " national standard of country's issue was divided into 14 classes with the fireworks and firecrackers product, wherein spraying decoration class, rotation class, rotation lift-off class, shelf fireworks series products be manufactured with a common ground: used pyrotechnic composition is a firework-spraying compositions, sprays pyrotechnic composition and puts into fireworks tube.
As everyone knows, pyrotechnic composition is a kind of mixture, all belongs to combustible and explosive articles, and is higher to the impact sensitivity and the friction sensitivity of mechanism.The operation of traditional filling firework gunpowder is divided into powder charge and builds two steps of medicine: in the fireworks tube of at first pyrotechnic composition for preparing being packed into, and then the pyrotechnic composition in the fireworks tube of packing into applied external force, the pyrotechnic composition compacting that to pack into, closely knit to guarantee the pyrotechnic composition of filling, can successively burn when making the pyrotechnic composition burning, reach and set off design effect.
Problem of this charging means ubiquity: because the effect of friction and external force, in powder charge with build in the medicine process pyrotechnic composition accident of blasting easily, the safety of threat to life and property, therefore, in GB11652-89 " the fireworks and firecrackers labor safety technical regulation " standard of country issue in 2005 strict regulation has been done in the powder charge and the operational procedure of building medicine, but in practical operation, a large amount of explosion accidents still takes place in the fireworks enterprise of various places, causes serious casualties and property loss.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method of safe, efficient filling firework-spraying compositions, carry out powder charge in this way, can effectively solve the powder charge of firework production process, build blast the easily present situation of accident of pharmaceutical worker's preface, ensure the person and the property safety of factory, compare with traditional filling pyrotechnic composition operation, can omit and build the medicine step, enhance productivity.
Technical scheme of the present invention is achieved in that the firework-spraying compositions that will the prepare fireworks tube of packing into behind the semifluid that is modulated into liquid state before the fireworks tube of packing into, then with pharmaceutical drying.
It is oxidant that firework-spraying compositions is selected potassium nitrate, nitrocotton etc. usually for use, selects potassium hyperchlorate, strontium carbonate, polyvinyl chloride, Al-Mg alloy powder, coating agent which has to be dissolved in alcohol before use, barium nitrate, phenolic resins, sulphur, sulphur, sodium oxalate etc. for use according to firework display effect and Formula Design.
Semifluid is the material between solid and liquid, liquid has flowability, the required shearing force of its distortion is very little, it is placed on what shape it just has in what shapes of containers. semifluid has some essential characteristics of liquid, have flowability, can keep same shape with container after putting into container.When the semifluid of the shape that is in a liquid state becomes when solid-state, be easy to make self shape to adapt to the shape of container, under certain conditions and can keep, make solid-state material keep the shape consistent with container.
Dextrin is soluble in water, is dissolved in to have very strong viscosity in the water; Phenolic resins is dissolved in alcohol and acetone, has viscosity after the dissolving, and both can both bring into play the effectiveness of adhesive.Liquid adhesive can with the firework medicament parcel wherein keep its flowability with after pyrotechnic composition mixes, more can make firework medicament have enough mechanical strengths, slow down the burning velocity of medicament, reduce the mechanical sensitivity of medicament, and can play the effect that improves the pyrotechnic composition stability.
The fireworks industry selects for use nitrocotton to make single-base powder and double-base powder, and the solvent of dissolving nitrocotton can be selected ketone, ester class, ethers, alcohols and itrate group compound or mixed solvent etc.Thinner claims " Tianna solution ", " banana oil " again, is a kind of colourless transparent liquid with banana vapour flavor that is mixed by organic solvents such as ester, alcohol, benzene, ketones.The firework medicament that contains nitrocotton can be dissolved in thinner, can reduce the friction sensitivity of pyrotechnic composition after the dissolving, prevents spontaneous combustion and blast.
Because the present invention has selected for use the solvent that adds water dextrin or effumability of easy drying the pyrotechnic composition of solid to be modulated the semifluid of the shape that is in a liquid state, the dextrin that adds behind the water can be dry rapidly in the short time at normal temperatures, volatile solvent can volatilize rapidly at short notice, can guarantee the drying of firework medicament, fully guarantee the firework display effect of fireworks design.
Pyrotechnic composition in the fireworks tube pack at dextrin after the dry and solvent evaporates, become by the semifluid of liquid state in the process of solid and can keep the same shape with fireworks tube, closely knit is filled in the pyrotechnic cup, and the pyrotechnic composition after the modulation has more viscosity, can strengthen the mechanical strength of firework medicament, slow down the burning velocity of medicament, reduce the mechanical sensitivity of medicament, can better improve the stability of pyrotechnic composition.Employing technique scheme operation does not need again pyrotechnics in the firework effect tube of packing into to be carried out external force and builds reality, has omitted and has built the medicine step, and can reach than tradition and build the better effect of medicine, effectively reduces powder charge, builds the explosion accident in pharmaceutical worker's preface, has realized goal of the invention.
