Abstract
The invention discloses excitation powder of a flying plate type electric detonator without detonating powder, relating to a detonator explosive. The invention aims to provide excitation powder which can be loaded under a certain pressure without obviously influencing the sensitivity, can be compacted to avoid powder leakage and can ensure the detonator to be reliably ignited. The technical scheme of the invention is as follows: the excitation powder comprises the following components in parts by weight: 3-7 parts of penthrite, 1-2 parts of potassium chlorate and 0-1 part of expanded perlite, wherein 350-450 milliliters of adhesive are added to every one kilogram of the mixed components; the apparent density of the penthrite is 0.7-0.9g/cm<3>; the purity of the potassium chlorate is no less than 90%; the adhesive is polyvinyl alcohol resin of which the concentration is 3-7%; and the penthrite is a coarse penthrite of which the particle size is 20-60 meshes or a mixture containing 50-70% of 20-60-mesh penthrite and 30-50% of 100-300-mesh penthrite. The invention is mainly used for producing the excitation powder of an electric detonator.
Description
Technical field
The present invention relates to a kind of cap explosive, particularly relate to a kind of at the used medicine that excites in the fling chip electric detonator without primary explosive.
Technical background
In the prior art, the initiation mechanism of fling chip electric detonator without primary explosive is: the electric igniting assembly energising is got angry electric igniter, impel and excite the medicine detonation in the excitation apparatus, under electric igniter and the high temperature and high pressure gas effect that excites the medicine detonation to produce, in the rigidity of excitation apparatus break because of high pressure in the pipe bottom, forms High Speed Flyer, the charging explosive in detonator of High Speed Flyer initiation by impact below, propagation of explosion is finished the detonation transmission step by step.
As the technological core of fling chip electric detonator without primary explosive, the medicine that excites of excitation apparatus is the energy that produces High Speed Flyer, plays a part to form a connecting link in blasting cap initiation.For guaranteeing reliable initiation, excite medicine must satisfy two conditions simultaneously: one, have certain sensitivity, be beneficial to electric igniter and excite; Its two, have the higher energy that detonates, be beneficial to produce High Speed Flyer.
At above-mentioned condition, fling chip electric detonator without primary explosive in advance adopts RDX(onit, i.e. Cyclotrimethylene trinitramine usually) excite medicine with the mixture of oxygenant or pure too peace.Because these two kinds excite medicine all to have behind the pressurized sensitivity defective that obviously descends, for guaranteeing the detonator reliable initiation, relevant filling process all requires the two to keep state of nature filling (following abbreviation " pine dress "), and can not the pressure-bearing filling.
Owing to excite medicine to be in the powder charge top layer of non-priming basal detonator, if it is uncovered that basal detonator keeps, what be prone to " pine dress " in transhipment basal detonator and detonator assembling process excites the medicine phenomenon of spreading pesticides, obvious to the quality product influence, also has certain potential safety hazard; If the medicine top that excites at " pine dress " installs shutoff elements such as igniting lead for retractable pencil additional, not only operation and cost can obviously increase, and also there is certain threat in the pressure that press-fits the transmission of shutoff element to the reliability that excites that excites medicine.
Summary of the invention
The object of the present invention is to provide a kind of novel fling chip electric detonator without primary explosive to excite medicine, it can bear certain pressure filling and not obvious its sensitivity that influences, and the energy compacting prevents to spread pesticides and guarantees the detonator reliable initiation, has production adaptability widely.
The technical solution used in the present invention is: a kind of fling chip electric detonator without primary explosive excites medicine, each component that comprises the following weight ratio example: pacify very much: Potcrate: pearlstone=3-7:1-2:0-1, said components is mixed each kilogram the inside, back and is added tackiness agent 350-450 milliliter.
In such scheme, the described too apparent density of peace is 0.7-0.9g/cm
3The purity of described Potcrate is not less than 90%; Described tackiness agent is a polyvinyl alcohol resin, and its concentration is 3%-7%; Described too the peace for granularity the 20-60 purpose slightly too the peace, or the 50%-70% granularity be the 20-60 order pacify very much with the 30%-50% granularity be the mixture that the 100-300 order is pacified very much.
The technological process of production of the present invention is summarized as:
Too peace, Potcrate and perlite sieve and are mixed in proportion, and add tackiness agent then and carry out granulation, cross the 20-40 mesh sieve, and through oven dry, the medicine that dries in the air sieves by the 80-100 mesh sieve then, temporary getting final product.
The medicine that excites of the present invention obtains following performance data through experiment and detection:
1, consistency and stability: under 20 ℃ ± 5 ℃, relative humidity 90%～95% envrionment conditions, the present invention with cover copper shell, flange steel and igniting head coexistence, long storage 24 months does not have the generation of obvious color change and corrosion phenomenon, balance moisture content 0.45%.
2, heat resistance: store 2h under 100～120 ℃ of environment, do not have blast and take place with combustion phenomena, medicament outward appearance, color and free-running property all do not have obvious change.
3, electrostatic sensitivity: the assembling short electric detonator is that 2000pF, series resistance are 0 Ω, charging voltage under-12kV the condition at electric capacity, and to payment to a porter-shell discharge of electrical detonator, detected result is qualified.
4, mechanical sensitivity: under " 1.96MPa, 90 °, 20mg " test conditions, friction sensitivity measured value of the present invention is that 16%(DDNP is 100%); Under " 2kg, 25cm, 30mg " test conditions, impact sensitivity measured value of the present invention is that 20%(DDNP is 100%).
5, resistance to pressure: when compacted density≤1.4 g/cm3, under airtight charging condition, the present invention can reliably be excited by electric igniter.
Can draw from every technical characterictic of foregoing invention, advantage of the present invention is: it is basic medicine that the present invention pacifies very much with high explosive, make sensitizing agent with Potcrate, make density with pearlstone and adjust agent, add the polyvinyl alcohol tackiness agent system of mixing and form, it can bear certain pressure filling and not obvious its sensitivity that influences, the energy compacting prevents to spread pesticides and guarantees the detonator reliable initiation, has production adaptability widely, and its manufacturing process is simple, cost is lower, reliable in quality.
