Description
Technical field
The present invention relates to a kind of for starting lifesaving ignition powder and the preparation technology thereof of oxygen powder column admittedly, applicable to electric ignition or mechanical ignition startup.
Background technology
Gu oxygen is to utilize rich oxygen containing oxymuriate or perchlorate generation pyrolysis to emit the emergency oxygen supply equipment of new generation of the principle development of oxygen.Gu the advantage of oxygen is: Gu the oxygen life-span is very long, need not spare part, ensure stronger; The oxygen-producing amount height, under the condition that produces equal oxygen, the volume of oxygen candle has only 1/3 of high-pressure oxygen cylinder volume, for solid oxygen transports, stores, arranges and provide convenience; Gu oxygen can carry out oxygen supply according to the oxygen supply mode of prior design, need not to regulate, use simple, reliable; Oxygen candle stores and uses all under atmospheric pressure state, does not have that Keep Clear-High Voltage, and gunslinging just at the oxygen candle of oxygen supply detonation, explosion hazard does not take place.Gu oxygen is non-maintaining, can reduce the maintenance cost behind the equipment.Gu the oxygen apparatus of oxygen supply now has been widely used in boats and ships naval vessels, aerospace, mine and various disaster field such as save oneself as the lifesaving emergency oxygen apparatus.Gu the oxygen powder column adopts compression molding, density is bigger, needs to cause startup by ignition system.Small-sized solid oxygen product is used for the solid oxygen self-rescue equipment of carried type, is applicable to that mechanical impact fire in a stove before fuel is added mode starts.Bigger solid oxygen product as colliery refuge chamber or life-saving capsule apparatus of oxygen supply, leaves equipment compartment in, does not carry, and is applicable to electric Starting mode, satisfies remote isolated operation and realizes control oxygen supply automatically.
The described ignition powder of Chinese patent CN1817824A adopts and to smear preparation technology by hand, exist density variation greatly, easily come off, quality conformance is relatively poor and production efficiency is lower problem.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art provides a kind of solid oxygen powder column that can ignite, high reliability, high low temperature use properties all to satisfy the corresponding product technological standard, realizes that automatic remote control starts the solid oxygen ignition powder of lifesaving of solid oxygen, the raising ignition powder batch quality of production and production efficiency.
The present invention also aims to provide the preparation method of the solid oxygen of above-mentioned lifesaving with ignition powder.
Technical solution of the present invention is: the solid oxygen ignition powder of a kind of lifesaving comprises that the raw material of following mass percent adopts pressing process to make: (except explanation was arranged, the ratio that adopts among the present invention was 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 be sodium chlorate, potassium perchlorate separately or compounding close use.248 ℃ of sodium chlorate fusing points, decomposition temperature are about 300 ℃, 525 ℃ of potassium perchlorate fusing points, and decomposition temperature is about 600 ℃.Adopt the ignition powder residue of the low oxygenant of decomposition temperature easily to flow, mobile poor, the forming of the oxygenant residue that decomposition temperature is high; The ignition powder that the different oxygenant of decomposition temperature height is formed can guarantee that ignition powder starts soon, residue does not flow.Low decomposition temperature oxygenate content is more high, and the aggravation of ignition powder flow phenomenon jeopardizes product safety; The high decomposition temperature oxygenate content is more high, starts slower; Reasonably the oxygenate content proportioning both can guarantee the reliability that ignition powder starts, and can guarantee that again the ignition powder residue does not flow.Simultaneously, the oxygenant decomposition produces oxygen, and can avoid other class ignition powder oxygenants to decompose toxic and harmfuls such as producing oxynitride.The oxygenant optimum content is sodium chlorate 40% ~ 42%, potassium perchlorate 20% ~ 22%.
Wherein combustible agent be metal iron powder, titanium valve separately or be used.The iron powder ignition temperature is 430 ℃, and the titanium valve ignition temperature is 375 ℃.The ignition temperature difference of different metal powder directly determines the igniting reliability; The metal powder of low ignition temperature easily causes ignition powder to splash; Low ignition temperature and high ignition temperature are used, and can guarantee that ignition powder both easily started, and did not splash again.Metal powder content is more high, and the ignition powder flow phenomenon increases, and jeopardizes product safety; Metal powder content is low excessively, and is easily flame-out under the ignition powder low temperature condition; Reasonably metal powder content both can guarantee the reliability that ignition powder starts, and can guarantee that again the ignition powder residue does not flow.The combustible agent optimum content is iron powder 14% ~ 15%, titanium valve 5% ~ 6%.
Catalyzer be cobalt chloride, ferric oxide separately or be used.The decomposition temperature of oxygenant is higher, and catalyzer plays the effect of the decomposition temperature that reduces sodium chlorate.The 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 can absorb chlorine, emits oxygen simultaneously.The 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.The mica powder optimum content is 0.2% ~ 1%.
Preparation technology's method of the present invention is as follows: above-mentioned raw materials is mixed after the weighing in proportion; Medicinal powder adds water and carries out the secondary mixing after mixing, and the weight ratio of mixing back medicinal powder and water is 100:4 ~ 100:5; On solid oxygen powder column top a spill medicine groove is arranged, the medicinal powder that ignites that mixes is for the second time packed into, and compacting gets the solid oxygen ignition powder of lifesaving in the spill medicine groove of solid oxygen powder column; The solid oxygen of lifesaving is evenly spread one deck 0.03 g/cm again with the ignition powder surface
2~ 0.05g/cm
2Titanium valve.
The density of secondary mixing prodrug powder is 1.35g/cm among the present invention
3~ 1.45g/cm
3, the solid oxygen of compacting gained lifesaving is 1.50g/cm with the density of ignition powder
3~ 1.60g/cm
3

3~ 1.65g/cm
3
The present invention comprises that also the solid oxygen powder column that the solid oxygen of lifesaving is spread behind the titanium valve with the ignition powder surface puts into 80 ° of C baking ovens, dries 24 hours, is cooled to room temperature.
In the preparation process, the ignition powder pressed density is crucial.Pressed density is less than normal, then easy loose the coming off of ignition powder; Pressed density is bigger than normal, and then too closely knit, ignition powder is difficult for lighting.Through calculating and the experiment improvement, by designing spacing depression bar, guarantee that the ignition powder pressed density is suitable, and high conformity.After powder column is put into oven for drying, assemble solid oxygen generator and can start 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 big, can reliable ignition consolidate the oxygen powder column; Ignition powder burning back residue does not flow, and guarantees product safety; Solve the low problem of processing quality difference efficient of prior art, being also advantageous in that compared with prior art.
