Problems solved by technology

However, the amount of additives in the above-mentioned patents is relatively large, which increases the cost
[0005] Unlike foreign researchers who mainly use mixed alcohols, ethers, ketones, and alkanes as synergists, domestic researchers use strong oxidants such as hydrogen peroxide and potassium perchlorate and ferrocene as the main synergist, and the amount of additives is greatly reduced. But there are problems of container corrosion and poor volatility

Abstract

The invention discloses a high-efficiency industrial gas which comprises the raw materials: industrial propane gas with the purity higher than 95% (weight percent), and liquid-phase synergistic additive accounting for 0.3-1.0% (weight percent) of the industrial propane gas. By adding a little liquid-phase synergistic additive into the propane gas, the high-efficiency industrial gas remarkably improves the burning temperature and efficiency; meanwhile, the liquid-phase synergistic additive of the high-efficiency industrial gas has low corrosivity for a container and good volatility.

Description

technical field [0001] The invention relates to a high-efficiency industrial gas; the gas can be used for metal cutting and welding. Background technique [0002] Dissolved acetylene has been used as industrial welding and cutting gas for a long time. Acetylene gas has high combustion temperature, fast combustion speed and good gasification under low temperature conditions. Currently, it still occupies a major share of the welding and cutting gas market. However, the production of calcium carbide, the main raw material for acetylene gas, requires a large amount of power consumption and causes environmental pollution, so the production cost of acetylene gas remains high. At the same time, acetylene gas has a wide explosion limit range (2.5%-80.0%), is easy to temper, and has high requirements for safe use. In recent years, the domestic development of acetylene gas substitutes has been relatively active, among which the use of propane has been fully studied. Propane gas is a...
