example 1

[0012] Prepare the following components by weight percentage:

[0013] Potassium peroxide 50.0

[0014] Sodium peroxide 16.5

[0015] Aluminum hydroxide 25.0

[0016] Manganese dioxide 5.0

[0017] Aluminum powder 3.5

[0018] The above-mentioned mixture is compressed into blocks, each weighing 45 grams.

[0019] Oxygen produced when the mixture decomposes is non-toxic. In the gas sample collected 10 to 12 seconds after the start of decomposition, no components other than water vapor were found. The volume of oxygen produced is 5.6-5.7 liters. The time for generating oxygen is 52-55 seconds (20-25° C.) and 67-70 seconds (-10° C.). The thermal stability of the mixture is 98-102°C. During decomposition, the mixture neither swelled nor fell apart.

example 2

[0021] Prepare the following components by weight percentage:

[0022] Potassium peroxide 56.0

[0023] Sodium peroxide 20.0

[0024] Aluminum hydroxide 15.0

[0025] Manganese dioxide 6.0

[0026] Aluminum powder 3.0

[0027] The above-mentioned mixture is compressed into blocks, each weighing 45 grams.

[0028] The volume of oxygen produced is 5.3-5.5 liters. The time for generating oxygen is 52-55 seconds (20-25° C.) and 67-70 seconds (-10° C.). The thermal stability of the mixture is 98-102°C. During decomposition, the mixture neither swelled nor fell apart.

example 3

[0030] Prepare the following components by weight percentage:

[0031] Potassium peroxide 60.0

[0032] Sodium peroxide 10.0

[0033] Aluminum hydroxide 20.0

[0034] Manganese dioxide 7.0

[0035] Aluminum powder 2.5

[0036] The above-mentioned mixture is compressed into blocks, each weighing 45 grams.

[0037] The volume of oxygen produced is 6.1-6.3 liters. The time to generate oxygen is 63-65 seconds (20-25°C) and 73-75 seconds (-10°C). The thermal stability of the mixture is 98-102°C. During decomposition, the mixture neither swelled nor fell apart.

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 [0001] This invention relates to oxygen, and more particularly to a process for producing oxygen. Background technique [0002] At present, there are various methods for producing oxygen, among which oxygen prepared from chemical raw materials contains a small amount of impurities harmful to the human body; some are not suitable for application under low or high temperature conditions. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for preparing oxygen that has good stability and can be used under low temperature or high temperature conditions. [0004] Technical scheme of the present invention is: [0005] The preparation method of oxygen of the present invention adopts the following components according to weight percentage: sodium peroxide 10-20 aluminum hydroxide 15-25 manganese dioxide 5-7 aluminum pow...
