Abstract
The invention aims to provide a manufacturing method of a potassium picrate-red lead silicon series electric ignition charge. The manufacturing method comprises the steps of: weighing, mixing, smearing the ignition charge and the like, so that the ignition charge has better flame sensitivity and lower mechanical strength; and thus, the ignition capacity of the electric ignition charge is high, and the intrinsic safety and reliability during production and use can be effectively improved.
Description
One. technical field:
The present invention relates to the industrial explosive production field, especially a kind of potassium picrate-red lead silicon is the manufacture method of electric firing medicine.
Two. background technology:
The commercial electric detonator mode of getting angry mainly adopts electrothermal method at present.Electrical fuze is to scribble priming around the metal bridge silk, under the initiation current effect of some strength (minimum firing current≤450mA), utilize the heat effect of electric current, scorching hot and get angry reliably rapidly by the bridge silk, and output some strength flame fill can, in order to light firer's element of delay powder or priming explosive.It generally is comprised of four parts: payment to a porter, sealing plug, bridge silk, priming.And that priming is flare point is low, and temperature of combustion is high to be that heat sensitivity is high, and ignition ability is strong, works the pyrotechnic composition of the effect of igniting.In commercial electric detonator, the effect of priming is that delay powder or priming explosive that needs are lighted are heated to flare point, is to be the sensitive medicament of heated filament to thermal sense.
The kind of medicament of igniting is more, and it is that priming and DDNP are priming etc. that charcoal is generally arranged, but has certain shortcoming.
Charcoal is that priming is by (C+KClO
3+ DDNP+ tackiness agent) forms, have the characteristics such as combustion speed is fast, flame is long, ignition ability is stronger, because Potcrate has stronger corrodibility, after the standing storage, payment to a porter and bridge silk are all had corrosion.And the inductance degree is high, and production security is poor, and DDNP production process wastewater flow rate is many and difficult.
Red lead silicon is that priming is by (Pb
3O
4+ Si+DDNP+ tackiness agent) forms, have the characteristics such as combustion speed is fast, the flame calcination is strong, and ignition ability is strong, solid product is many.But because its friction sensitivity and mechanical sensitivity are high, susceptibility is higher, is unfavorable for the safety in basal detonator production and the assembling process.
The shortcomings such as relevant sensitizing agent such as the preparation process such as DDNP, nickel hydrazine nitrate are big for environment pollution.
Three. summary of the invention
Be the manufacture method of electric firing medicine by inventing a kind of potassium picrate-red lead silicon, it is had preferably flame sensitivity and lower mechanical sensitivity are arranged, therefore the ignition ability of this electric firing medicine is strong, and can Effective Raise production and the essential safety reliability of use procedure.
A kind of potassium picrate-red lead silicon is that the manufacture method step of electric firing medicine is as follows:
A, weighing mix: take by weighing 50 gram potassium picrates (water content is less than 0.1%), 50 gram red lead ferrosilicon meals (ratio is 9:1), measure polyvinyl alcohol water solution 15ml, pour into successively in the glass beaker of 300ml, stir with bakelite rod, then sieve, continue to stir 40 minutes, to be mixed evenly after, leave standstill use.
B, smear priming: mixed around the bridge silk that thick medicament evenly is put on electric match above-mentioned, the igniting head that wipes does not allow to occur pore, crackle, damaged and bridge silk and the bad phenomenon such as exposes, and the weight of igniting head is between 8～12mg.With 35～45 ℃ dry to water content less than 0.1%, namely finish priming manufacturing of the present invention.
The present invention selects polyvinyl alcohol water solution to make tackiness agent, and its main component is polyvinyl alcohol, and concentration is 9～12%(weight).Its bonding effect is good, in production and application and transportation, is difficult for occuring electrical fuze fragmentation and obscission;
The present invention has preferably flame sensitivity and lower mechanical sensitivity, therefore the ignition ability of this electric firing medicine is strong, and can Effective Raise production and the essential safety reliability of use procedure;
The present invention uses red lead-ferrosilicon mixture to do additive, and the red lead ferrosilicon can not produce corrosion to payment to a porter and bridge silk, and medicament formation degree and hardness effect are better.
The invention has the advantages that: 1. ignition ability is strong, and under galvanic action, Fire Reliability is high, and every electrical parameter index all meets GB " GB8031-2005 "; 2. have lower mechanical sensitivity and friction sensitivity, improve the security of electrical detonator in production and assembling process; 3. payment to a porter and the bridge silk of electrical fuze are not had corrodibility, satisfy the requirement of standing storage; 4. have higher shaping degree and hardness, and without bubble, effectively raise Fire Reliability, reduce electrical fuze fragmentation or obscission in the production and transport process; 5. potassium picrate production process, the waste water recoverable is conducive to protection of the environment.
Four. description of drawings
Fig. 1 is that a kind of potassium picrate of the present invention-red lead silicon is the process flow sheet of the manufacture method of electric firing medicine.
Five. embodiment
The present invention is described in further detail below in conjunction with accompanying drawing 1 and embodiment.As shown in the figure:
Example of making is: weighing mixes: take by weighing 50 gram potassium picrates (water content is less than 0.1%), 50 gram red lead ferrosilicon meals (ratio is 9:1), measure polyvinyl alcohol water solution 15ml, pour into successively in the glass beaker of 300ml, stir with bakelite rod, then sieve, continue to stir 40 minutes, to be mixed evenly after, leave standstill use.
Smear priming: mixed around the bridge silk that thick medicament evenly is put on electric match above-mentioned, the igniting head that wipes does not allow to occur pore, crackle, damaged and bridge silk and the bad phenomenon such as exposes, and the weight of igniting head is between 8～12mg.With 35～45 ℃ dry to water content less than 0.1%, namely finish priming manufacturing of the present invention.
Above-described embodiment, the present invention embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
