Abstract
The present invention relates to a low performance compound potassium powder additive for fireworks and firecrackers. The present invention uses the following raw materials of the weight proportion and technology: (1) 30% to 50% of potassium chloride is evenly mixed with 50% to 70% of sodium chlorate; the potassium chloride reacts with the sodium chlorate in the condition of the steam of 100 DEG C for three to five hours; (2) the product is cooled, and sodium chloride is separated; the semi-finished product of potassium chlorate is obtained; (3) the potassium chlorate is soaked twice for solution; potassium nitrate with the weight of 10% to 40% of the weight of potassium chlorate and barium nitrate with the weight of 10% to 40% of the weight of potassium chlorate are added; the potassium chlorate, the potassium chlorate and the barium nitrate are naturally cooled to be crystallized, washed, centrifuged, dehumidificated, dried and pulverized to the degree of 200 to 250 meshes after reacting for two to four hours in the condition of the steam of 100 DEG C; light calcium carbonate with the weight of 5% to 10% of the weight of a pulverized object is added to be evenly mixed together to form the potassium powder additive. The present invention has the advantages of high safety, low moisture absorption and high purity. The present invention is made into the firecrackers with strong explosive force.
Description
Technical field
The present invention relates to a kind of gunpowder that is used for fireworks.
Background technology
In the prior art, chloric acid salt gunpowder (as Potcrate) is a main raw material of producing match, fireworks, this is because chloric acid salt gunpowder has characteristics such as oxidisability is strong, blast performance good, igniting is easy, the mixing firework medicament that particularly with Potcrate is oxygenant has good inflammableness, explosiveness and helps look, therefore is used widely in civilian pyrotechnics industry.But, because the mechanical sensitivity height of chloric acid salt gunpowder, Potcrate can not grind altogether with organism, mixing with sulphur, phosphorus and organism or combustiblematerials and rubbing or when clashing into, very easily blast, security incident in use easily takes place, and this brings massive losses not only for national economy and people's lives and properties, returns the producer and brings heavy psychological pressure.
Summary of the invention
The technical problem to be solved in the present invention is that the defective at prior art exists proposes the compound potassium powder additive of a kind of low property, has the advantages that firer's performance is good, security is good, rate of moisture absorption is low and cost is low.
Technical solution of the present invention is that the compound potassium powder additive of described low property adopts following raw material and technology to make:
(1) potassium chloride 30%-50% (weight part) and sodium chlorate 50%-70% (weight part) mix, and reaction is 3-5 hour under 100 ℃ of steam conditions;
(2) cool off above-mentioned resultant, isolate sodium-chlor, obtain work in-process Potcrate;
(3) described Potcrate is soaked the secondary dissolving, add again and be equivalent to the saltpetre of Potcrate weight 10%-40% and the nitrate of baryta of 10%-40%, after reacting 2-4 hour under 100 ℃ of steam conditions, natural cooling crystallization, washing, centrifugally dry, drying and crushing is to the 200-250 order, adding is equivalent to the light calcium carbonate of crushed material weight 5%-10% and mixes, promptly.
Production technique of the present invention does not have " three wastes " and produces, and product performance are stable and security is good, and mechanical means is simple, normal pressure production, power consumption are little, and cost is lower.
As known from the above, the present invention is the low compound potassium powder additive of property, and its feature has:
1, friction sensitivity 35%, and impact sensitivity 28% is better than national standard (friction sensitivity≤60%, impact sensitivity≤50%).Be used for firecrackers production, after this product and aluminium silver powder, sulphur were pressed proportioning and medicine, generally firmly hammer was loud with iron hammer for hand.
2, volume is the same with Potcrate, equal consumption, and equal effect does not increase cost.
Do not need an application when 3, prevented from caking, this product are continued to employ some months and medicine, reduced operating procedure.
4, muriate, moisture content, water-insoluble, vitriol, rate of moisture absorption all can reach the national standard of Potcrate.
Product of the present invention must meet following technical indicator:
| Project | Index |
| K(KCLO 3) content % 〉= | 65 |
| A2 content % 〉= | 34 |
| Moisture %≤ | 0.1 |
| Water do molten thing content %≤ | 0.1 |
| Muriate (in Cl) content %≤ | 0.03 |
| Impact sensitivity %≤ | 28 |
| Friction sensitivity %≤ | 35 |
| Rate of moisture absorption≤ | 2 |
Examination and test of products method of the present invention: potassium chlorate content, moisture, water are not tolerant, chloride content is undertaken by the method for GBT52-94 regulation.Impact sensitivity is measured by the method for QB-/T1941.2-94 regulation and is undertaken.The friction sensitivity regulation is undertaken by the method for QB-/T1941.3-94 regulation.Rate of moisture absorption is measured by the method for Q/T1941.5-94 regulation and is undertaken.
Examination and test of products rule: the method by the GBT52-94 regulation is carried out.
Product marking, packing, transportation, storage: the method by the GB752-94 regulation is carried out.
Embodiment

(2) cool off above-mentioned resultant, isolate sodium-chlor, obtain work in-process Potcrate;
(3) described Potcrate is soaked the secondary dissolving, add again and be equivalent to the saltpetre of Potcrate weight 30% and 30% potassium hydroxide, reaction is 2-4 hour under 100 ℃ of steam conditions, natural cooling crystallization, washing, centrifugally dry, drying, be crushed to 250 orders, adding is equivalent to the light calcium carbonate of crushed material weight 8% and mixes, promptly.
