Problems solved by technology

[0003] However, during the oxygen supply process of chlorate-type oxygen candles, its unstable combustion will inevitably affect the oxygen production rate. If oxygen production is too fast, the oxygen supply time will be insufficient or oxygen production will be too slow (even if the flame is turned off to stop oxygen supply), it will be used. Therefore, it is of great significance to study the combustion stability of chlorate-type oxygen candles.

Abstract

The invention discloses a chlorate oxygen candle with stable combustion for oxygen supply and a preparation method of the chlorate oxygen candle. The chlorate oxygen candle comprises a main candle body and a combustible medicine layer, wherein the main candle body is prepared from, by weight, 70-88 parts of sodium chlorate, 1-15 parts of potassium perchlorate, 2-6 parts of fuel, 0.5-5 parts of acatalyst, 1-8 parts of a chlorine inhibitor, 1-8 parts of a binder and 2-5 parts of a broken metal piece; the combustible medicine layer is prepared from, by weight, 75-86 parts of sodium chlorate, 1-5 parts of potassium perchlorate, 2-10 parts of fuel, 1-5 parts of a catalyst, 2-8 parts of a chlorine inhibitor and 0.5-4 parts of a broken metal piece. The preparation method includes the steps: preparation of the main candle body, namely evenly dry-blending the raw materials added with 0.5% of distilled water by evenly wet-blending; preparation of the combustible medicine layer, namely evenlydry-blending the raw materials added with 0.5% of distilled water by evenly wet-blending; loading a mould press between positions under the main candle body and above the combustible medicine layer for compression molding prior to placing in an oven for 14 hours at 120-140DEG C after demolding. The chlorate oxygen candle is good in heat-transfer performance, and heat generated from combustion cannot be accumulated to cause combustion to increase; post-combustion residues are less prone to flow, and stable combustion for oxygen supply is guaranteed.

Description

technical field [0001] The invention relates to an oxygen candle for stable combustion and oxygen supply and a preparation method thereof, in particular to a chlorate decomposition oxygen production technology. Background technique [0002] Chlorate oxygen candle oxygen production is to use oxygen-rich chlorate or perchlorate to undergo thermal decomposition reaction to release oxygen. It is an important oxygen source for operation, lifesaving and escape oxygen supply in various anoxic environments. Also known as fixed oxygen. Its advantages are: long life, no need for spare parts, more powerful guarantee; high oxygen production, under the same oxygen production conditions, the volume of solid oxygen is only 1 / 3 of the volume of high-pressure oxygen cylinders, which is convenient for transportation, storage and arrangement; Oxygen can be supplied according to the pre-designed oxygen supply method without adjustment, and it is simple and reliable to use; both storage and use...
