Problems solved by technology

[0002] The traditional metal welding and cutting gas generally uses acetylene gas, mainly because of its simple and quick preparation and low cost. However, due to its high carbon content, the mixing ratio of acetylene with oxygen is not easy to control during use, and black smoke is easy to be generated. Moreover, such a combustion state will also reduce the combustion temperature of acetylene, which will have a great adverse effect on metal welding or cutting
[0003] And at room temperature and normal pressure, because there are a large number of covalent bonds in its molecular structure to interact, the acetylene gas molecules have the characteristics of mutual agglomeration, so it is easy to produce larger molecular clusters, which reduces the molecular weight of acetylene. Combustion performance makes it difficult for acetylene gas to burn completely, which affects its combustion value and welding and cutting speed, and is not conducive to environmental protection
[0004] Due to the reduction of the combustion performance of acetylene, it is necessary to increase the airflow cross section and airflow velocity of oxygen or air during use, which increases the difficulty of welding or cutting control, and the shape and intensity of the flame are not easy to control, which will lead to welding or cutting The quality of the

Embodiment Construction

[0020] The invention is further described below.

[0021] The present invention includes a mother liquor, which is liquefied C 3 For liquefied petroleum gas, a catalyst and a combustion aid are added to the mother liquor, the catalyst is petroleum spirit, and the combustion aid is potassium permanganate solution.

[0022] Petroleum spirit as a catalyst, also called petroleum ether, is a colorless and transparent liquid extracted from petroleum. Has a special odor. No fluorescence, low viscosity, does not solidify when cold. The boiling point is 30-120°C, and the relative density is 0.625-0.660. Miscible with ethanol, ether, benzene, chloroform, carbon disulfide, carbon tetrachloride and oils (except castor oil). Insoluble in water, highly volatile, flammable, steam mixed with air can cause explosion. Generally, it is mainly used as a solvent.

[0023] In the present invention, petroleum spirit is mixed into the mother liquor as an additive, which can first increase the g...
