Abstract

The invention relates to the technical field of air regeneration oxygen generation self-rescue medicine plates for navy submarines and other places, particularly to a potassium air regeneration medicine plate, which is prepared from the following raw materials in parts by weight: 90-97 parts of potassium superoxide and 3-10 parts of chrysotile, wherein the length of the chrysotile ranges from 3 mmto 8 mm, the tensile strength of the chrysotile ranges from 2800 MPa to 3000 MPa, and the hardness of the chrysotile ranges from 2.1 to 2.4. The invention further provides a manufacturing method of the medicine plate, wherein the manufacturing method comprises the steps of chrysotile impurity removal, material mixing, medicine plate pressing, heat treatment and forming. According to the medicineplate obtained through the formula and the method, the highest load can reach 1600 g, and the highest porosity can reach 52%, so that the absorption capacity of the medicine plate to carbon dioxide can be improved, and the oxygen production performance of the medicine plate is enhanced; and collapse is avoided in the pressing forming process, the forming rate is high, and the machining efficiencyis relatively improved.

Description

technical field [0001] The invention relates to the technical field of an air-regenerated oxygen-generating self-rescue medicine board used in naval submarines and other places, in particular to a potassium air-regenerated medicine board and a manufacturing method thereof. Background technique [0002] In fields such as aviation, submarines, mines, etc., the human body is required to survive in a confined space for a period of time under some special circumstances. When the human body survives in a confined space for a long time, it needs to control the balance of carbon dioxide and oxygen in the confined space. If the oxygen is too low or the carbon dioxide is too high, it will be fatal. [0003] At present, potassium superoxide is usually used as an oxygen generating agent, which adapts to the respiratory entropy of the human body, and releases oxygen while absorbing carbon dioxide. Since the apparent specific gravity of potassium superoxide powder is 0.4-0.6g / ml, if it i...
