Abstract
In the oxygen preparing process for portable respirator, the materials including sodium peroxide 10-20 wt%, aluminum hydroxide 15-25 wt%, manganese dioxide 5-7 wt% and aluminum powder 2.5-3.5 wt% as well as potassium hydroxide the rest are used. The present invention has excellent effect of producing oxygen and moisture, can produce oxygen reliably in the temperature over minus 10 deg.c, and may be used widely in various respirators.
Description
Technical field
The invention relates to oxygen, more particularly the preparation method of oxygen.
Background technology
At present, the method for making oxygen is varied, and wherein by the oxygen of chemical feedstocks preparation, what have contains a small amount of harmful impurity; Then being not suitable for of having used under low temperature or pyritous condition.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, the preparation method of the oxygen that provide a kind of good stability, can under low temperature or hot conditions, use.
Technical solution of the present invention is:
The preparation method of oxygen of the present invention, adopt following component by weight percentage: sodium peroxide 10～20 aluminium hydroxides 15～25 Manganse Dioxide 5～7 aluminium powders 2.5～3.5 surpluses are Potassium peroxide.
Prescription of the present invention adopts Potassium peroxide and sodium peroxide as the composition that produces.Adopt aluminium hydroxide, Manganse Dioxide and aluminium powder as the activator composition.
The oxygen of the present invention's preparation has good effect, and it can not only be produced for the oxygen of breathing usefulness, but also the production aqueous vapor.This is extremely important to respiration apparatus.Oxygen of the present invention performance under-10 ℃ temperature is still very reliable.
The present invention uses Potassium peroxide (KO
2) and sodium peroxide (NaO
2) can eliminate the possibility that release has poison gas gas, because these compounds are compared with the oxymuriate of alkali metals, better reactivity is arranged.
The reason that adds activator in the present invention is aluminium hydroxide (AL (OH))
3) be the source of production aqueous vapor.This is the important factor of preparation oxygen.Manganse Dioxide (MnO
2) play catalyst action, it can promote sodium peroxide to decompose, because solid-state sodium peroxide can not be emitted oxygen fully.
Embodiment
Case introduction of the present invention is as follows:
Example one
Get following component by weight percentage ready:
Potassium peroxide 50.0
Sodium peroxide 16.5
Aluminium hydroxide 25.0

Example three
Get following component by weight percentage ready:
Potassium peroxide 60.0
Sodium peroxide 10.0
Aluminium hydroxide 20.0
Manganse Dioxide 7.0
Aluminium powder 2.5
Above-mentioned compound is pressed into bulk, every heavy 45 grams.
The volume that produces oxygen is 6.1～6.3 liters.The oxygenous time is 63～65 seconds (20～25 ℃) and 73～75 seconds (10 ℃).The thermostability of compound is 98～102 ℃.In the process of decomposing, compound had not both had expansion not scatter yet.
Example four
Get following component by weight percentage ready:
Potassium peroxide 67.5
Sodium peroxide 10.0
Aluminium hydroxide 15.0
Manganse Dioxide 5.0
Aluminium powder 2.5
Above-mentioned compound is pressed into bulk, every heavy 45 grams.
The volume that produces oxygen is 5.4～5.6 liters.The oxygenous time is 28～30 seconds (20～25 ℃).With the thermostability of 45～48 seconds (10) compounds be 98～102 ℃.In the process of decomposing, compound had not both had expansion not scatter yet.
Example five
Get following component by weight percentage ready:
Potassium peroxide 56.0
Sodium peroxide 20.0
Aluminium hydroxide 15.0
Manganse Dioxide 6.0
Aluminium powder 3.0
Above-mentioned compound is pressed into bulk, every heavy 45 grams.
The volume that produces oxygen is 5.3～5.5 liters.The oxygenous time is 52～55 seconds (20～25 ℃) and 67～70 seconds (10 ℃).The thermostability of compound is 98～102 ℃.In the process of decomposing, compound had not both had expansion not scatter yet.
As mentioned above, the oxygen of manufacturing of the present invention need be made " block compound " in advance.These compounds can provide the oxygen of enough breathing usefulness very soon.These compounds neither contain deleterious impurity, also do not decompose voluntarily when low temperature or high temperature.When respiration apparatus was started working, it can the production aqueous vapor.These block compounds are to be pressed into certain size and dimension under certain pressure.
The block compound that prescription according to the present invention makes is placed in the wire cloth container of lid usually, and then container is put into the regeneration toxin filter apparatus.
