Description
Technical field
The present invention relates to a kind of ignition powder and the preparation technology thereof that consolidate oxygen powder column for starting lifesaving, being applicable to electric ignition or mechanical ignition startup.
Background technology
Gu oxygen is the emergency oxygen supply equipment of new generation utilizing rich oxygen containing oxymuriate or perchlorate generation pyrolysis to release the principle development of oxygen.Gu the advantage of oxygen is: Gu the oxygen life-span is very long, without the need to spare part, ensure stronger; Oxygen-producing amount is high, and under the condition producing equal oxygen, the volume of oxygen candle only has 1/3 of high-pressure oxygen cylinder volume, for solid O_2 transport, storage, layout are provided convenience; Gu oxygen can carry out oxygen supply according to the offering oxygen way of design in advance, without the need to regulating, use simple, reliable; Oxygen candle stores and uses all under atmospheric pressure state, does not have that Keep Clear-High Voltage, and gunslinging is just being lit up at the oxygen of oxygen supply and detonation, explosion hazard do not occurred.Gu oxygen is non-maintaining, the maintenance cost after equipment can be reduced.Gu oxygen apparatus of oxygen supply has now been widely used in boats and ships naval vessels, aerospace, mine and various disaster as lifesaving emergency oxygen apparatus and the field such as has saved oneself.Gu oxygen powder column adopts compression molding, density is comparatively large, need be caused start by ignition system.Small-sized solid oxygen product, for the solid oxygen self-rescue equipment of carried type, is applicable to mechanical impact fire in a stove before fuel is added mode and starts.Larger solid oxygen product, as coal mine refuge chamber or life-saving capsule apparatus of oxygen supply, leaves equipment compartment in, does not carry with, be applicable to electric Starting mode, meets remote isolated operation and realizes automatically controlling oxygen supply.
Ignition powder described in Chinese patent CN1817824A, adopts and smears preparation technology by hand, there is the problem that density variation comes off greatly, easily, quality conformance is poor and production efficiency is lower.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art provide a kind of solid oxygen powder column that can ignite, high reliability, high/low temperature use properties all to meet corresponding product technological standard, realize the solid oxygen ignition powder of lifesaving that automatic remote control starts solid oxygen, the raising ignition powder batch quality of production and production efficiency.
The present invention also aims to the preparation method that the solid oxygen ignition powder of above-mentioned lifesaving is provided.
Technical solution of the present invention is: the solid oxygen ignition powder of a kind of lifesaving, and the raw material comprising following mass percent adopts pressing process to make: (apart from outside explanation, the ratio adopted in the present invention is weight proportion)
Sodium chlorate 32% ~ 44%; Potassium perchlorate 20% ~ 30%; Iron powder 14% ~ 18%; Titanium valve 4% ~ 8%; Cobalt chloride 5% ~ 12%; Ferric oxide 3% ~ 7%; Barium peroxide 0.5% ~ 5%; Mica powder 0.1% ~ 1.5%.
Wherein oxygenant is sodium chlorate, potassium perchlorate is independent or join used in combination.Sodium chlorate fusing point 248 DEG C, decomposition temperature is about 300 DEG C, potassium perchlorate fusing point 525 DEG C, and decomposition temperature is about 600 DEG C.The ignition powder residue of the low oxygenant of decomposition temperature is adopted easily to flow, poor, the forming of oxygenant residue flowing that decomposition temperature is high; The ignition powder of the oxygenant composition that decomposition temperature height is different can ensure that ignition powder starts soon, residue does not flow.Low decomposition temperature oxygenate content is higher, and ignition powder flow phenomenon aggravates, and jeopardizes product safety; High decomposition temperature oxygenate content is higher, starts slower; Rational oxygenate content proportioning both can ensure the reliability that ignition powder starts, and can ensure that again ignition powder residue does not flow.Meanwhile, oxidizer decomposes produces oxygen, and other class ignition powder oxidizer decomposes can be avoided to produce the toxic and harmfuls such as oxynitride.Oxygenant optimum content is sodium chlorate 40% ~ 42%, potassium perchlorate 20% ~ 22%.
Wherein combustible agent be metal iron powder, titanium valve separately or with the use of.Iron powder ignition temperature is 430 DEG C, and titanium valve ignition temperature is 375 DEG C.The ignition temperature of different metal powder is different, directly determines igniting reliability; The metal powder of low ignition temperature easily causes ignition powder to splash; Low ignition temperature and high ignition temperature with the use of, can ensure that ignition powder both easily started, and did not splash again.Metal powder content is higher, and ignition powder flow phenomenon increases, and jeopardizes product safety; Metal powder content is too low, easily stops working under ignition powder low temperature condition; Rational metal powder content both can ensure the reliability that ignition powder starts, and can ensure that again ignition powder residue does not flow.Combustible agent optimum content is iron powder 14% ~ 15%, titanium valve 5% ~ 6%.
Catalyzer be cobalt chloride, ferric oxide separately or with the use of.The decomposition temperature of oxygenant is higher, and catalyzer plays the effect of the decomposition temperature reducing sodium chlorate.Catalyzer optimum content is cobalt chloride 8% ~ 10%, ferric oxide 4% ~ 6%.
Chlorine-inhibiting agent is barium peroxide.Oxygenant is oxymuriate and perchlorate, and pyrolytic decomposition easily produces chlorine, and barium peroxide Absorbable rod chlorine, releases oxygen simultaneously.Chlorine-inhibiting agent optimum content is barium peroxide 1% ~ 3%.
Other additive mica powders.Mica powder plays skeleton function, strengthens the intensity of ignition powder.Mica powder optimum content is 0.2% ~ 1%.
Process of preparing of the present invention is as follows: mix after above-mentioned raw materials in proportion weighing; The rear medicinal powder of mixing adds water and carries out secondary mixing, and after mixing, the weight ratio of medicinal powder and water is 100:4 ~ 100:5; There is a spill medicine groove on solid oxygen powder column top, the medicinal powder that ignites of second time mixing is loaded compacting in the spill medicine groove of solid oxygen powder column and obtains the solid oxygen ignition powder of lifesaving; Solid oxygen ignition powder surface uniform spreading one deck 0.03 g/cm again of lifesaving
2~ 0.05g/cm
2titanium valve.
In the present invention, before secondary mixing, the density of medicinal powder is 1.35g/cm
3~ 1.45g/cm
3, the density of the solid oxygen ignition powder of compacting gained lifesaving is 1.50g/cm
3~ 1.60g/cm
3.
The present invention is also included in the solid oxygen ignition powder surface of lifesaving after uniform spreading layer of metal titanium valve, and again compress, after compressing, the density of the solid oxygen ignition powder of lifesaving is 1.55g/cm
3~ 1.65g/cm
3.
The present invention also comprises the solid oxygen powder column after by solid for lifesaving oxygen ignition powder surface paving titanium valve and puts into 80 ° of C baking ovens, dries 24 hours, is cooled to room temperature.
In preparation process, ignition powder pressed density is crucial.Pressed density is less than normal, then ignition powder is easily loose comes off; Pressed density is bigger than normal, then too closely knit, ignition powder is not easily lighted.Through calculating and experiment Innovatation, by designing spacing depression bar, guarantee that ignition powder pressed density is suitable for, and consistence is good.After powder column puts into oven for drying, assemble solid oxygen generator and can carry out startup experiment.
The present invention adopts electric igniter or the igniting of the mechanical impact fire in a stove before fuel is added, and its energy is higher, and surging force is large, reliable ignition can consolidate oxygen powder column; After ignition powder burning, residue does not flow, and guarantees product safety; Solve the low problem of processing quality difference efficiency of prior art, being also advantageous in that compared with prior art.
