Description
Technical field:
The present invention relates to the method for manufacture of priming charge in the commercial electric detonator electric match, the method for manufacture of particularly a kind of nickel hydrazine nitrate-red lead silicon mooring points gunpowder.
Background technology:
Commercial electric detonator is scorching hot bridge-wire electric detonator; Electric match is to scribble priming charge around the metal bridge silk, and is under the initiation current effect of certain intensity, scorching hot and get angry reliably rapidly through the bridge silk; And the flame of exporting certain intensity dash can, in order to light firer's element of delay powder or priming explosive.It generally is made up of four parts: payment to a porter, sealing plug, bridge silk, priming charge.And priming charge is the heat sensitivity height, and ignition ability is stronger, works the pyrotechnic composition of the effect of igniting.In commercial electric detonator, the effect of priming charge is the flame that produces ignite delay powder or priming explosive, is to be the sensitive medicament of heated filament to thermal sense.
The kind of priming charge is more, DDNP mooring points gunpowder, charcoal mooring points gunpowder and red lead silicon mooring points gunpowder etc. is generally arranged, but all have certain shortcoming:
Charcoal mooring points gunpowder is by (C+KClO
3+ tackiness agent) form, its conduction time is 8～10ms, has characteristics such as combustion speed is low, flame is little, ignition ability is weak, the inductance degree is lower, and moisture-sensitive, after the long storage (12 months), to payment to a porter and bridge silk seriously corroded.
DDNP mooring points gunpowder is by (DDNP+Sb
2S
3+ KClO
3+ tackiness agent or DDNP+C+KClO
3+ tackiness agent) form, its conduction time is 4～8ms, have characteristics such as combustion speed is fast, flame is long, ignition ability is stronger, but gas vol is big, after the long storage (12 months), payment to a porter and bridge silk is all had corrosion.And the inductance degree is higher, and production security is poor, and DDNP production process wastewater flow rate is many and hard to manage.
Red lead silicon mooring points gunpowder is by (Pb
3O
4+ Si+DDNP+ tackiness agent) form, its conduction time 4～6ms has characteristics such as combustion speed is fast, flame calcination property is strong, ignition ability is strong, solid product is many.But, be unfavorable for the safety in electrical detonator production and the assembling process because of its friction sensitivity and mechanical sensitivity height.
Summary of the invention:
The objective of the invention is to overcome the defective that above-mentioned each medicament exists, the method for manufacture of a kind of nickel hydrazine nitrate-red lead silicon mooring points gunpowder is provided.
Scheme of the present invention is: priming charge comprises red lead-ferrosilicon, it is characterized in that: the priming charge base-material is in 100 gram weight, and its proportioning is: nickel hydrazine nitrate 85～92 grams, red lead-ferrosilicon 8～15 restrain, wherein the nickel hydrazine nitrate bulk specific weight is 0.75～1.10 gram/cm
3, water cut less than 0.1%, the red lead of red lead-ferrosilicon and the proportioning of ferrosilicon be 75%: 25%; With nickel hydrazine nitrate, red lead-ferrosilicon uniform mixing, measure staple again and be Z 150PH, concentration and be 8～10% aqueous solution 15ml and basic medicine and mix to stir and produce thick priming charge.
The invention has the advantages that: 1. ignition ability is strong, and under galvanic action, the safety of getting angry is high; 2. have lower mechanical sensitivity, improve the security of electrical detonator in production and assembling process; 3. payment to a porter and the bridge silk to electric match do not have corrodibility, satisfies the requirement of long storage; 4. has higher shaping degree and hardness, to reduce electric match fragmentation or obscission in the production and transport process.5. nickel hydrazine nitrate production process, waste water is recyclable, helps environment protection.
Description of drawings:
Accompanying drawing is a product structure synoptic diagram of the present invention.
Embodiment:
Priming charge of the present invention comprises red lead-ferrosilicon, it is characterized in that: the priming charge base-material is in 100 gram weight, and its proportioning is: nickel hydrazine nitrate 85～92 grams, red lead-ferrosilicon 8～15 restrain, wherein the nickel hydrazine nitrate bulk specific weight is 0.75～1.10 gram/cm
3, water cut less than 0.1%, the red lead of red lead-ferrosilicon and the proportioning of ferrosilicon be 75%: 25%; With nickel hydrazine nitrate, red lead-ferrosilicon uniform mixing, measure staple again and be Z 150PH, concentration and be 8～10% polyvinyl alcohol water solution 15ml and basic medicine and mix to stir and produce thick priming charge.
Since nickel hydrazine nitrate not with metal reactions such as copper, iron, have advantages of good anticorrosion performance; Nickel hydrazine nitrate has flame sensitivity and lower mechanical sensitivity preferably again, so the ignition ability of this priming charge is strong, and can effectively improve the security of production and use.
The present invention uses red lead-ferrosilicon mixture to do additive, and red lead silicon can not produce corrosion to payment to a porter and bridge silk, and medicament shaping degree and hardness are all preferable.Because of the usage quantity of red lead significantly reduces than red lead silicon mooring points gunpowder consumption, can reduce plumbous harm to environment.
The present invention selects for use polyvinyl alcohol water solution to make tackiness agent, and its staple is a Z 150PH, and concentration is 8～10% (weight).Its bonding effect is good, in producing use and transportation, is difficult for taking place electric match fragmentation and obscission.
Example of making is:
Weighing mixes: taking by weighing 90 gram bulk specific weights is 0.90 gram/cm
3Nickel hydrazine nitrate saccharoid (water cut is less than 0.1%), 10 gram red lead silicon meals (ratio is 75: 25), measure polyvinyl alcohol water solution 15ml; Pour into successively in the glass beaker of 300ml; The back is stirred 8～10 minutes to mixing set aside for use with bakelite rod.
Be coated with priming charge: mixed around the bridge silk that thick medicament evenly is applied to electric match above-mentioned, the match board head that has been coated with does not allow to occur pore, crackle, damaged, bridge silk and weld cap and bad phenomenon such as exposes, and the weight of point of amorce is between 8～16mg.In 35～45 ℃ of temperature dry to water content less than 0.1%, promptly accomplish priming charge manufacturing of the present invention.
