Problems solved by technology

Acetylene and propane have the following disadvantages as cutting and welding industrial gas: (1) Acetylene and propane are flammable, explosive and toxic gases with low safety factor, easy to deposit carbon, and emit black smoke and smoke when ignited, polluting the working environment and harming the human body. Harmful to health; (2), the price of acetylene and propane is high, the use efficiency is low, and the waste of resources is large; (3), the continuous use time of acetylene and propane is short during use, and the tank needs to be changed frequently, the labor efficiency is low, and the cutting seam Large, waste raw materials, the cutting surface is prone to excessive deformation during the cutting process, the upper edge burns down, and the phenomenon of dross hanging on the lower edge; (4), the preheating time for acetylene and propane cutting is long, the cutting speed is slow, and the cutting surface It is easy to hang slag, undercut, and difficult to clean; (5), acetylene and propane contain hydrogen sulfide and phosphine, if the desulfurization and deacidification are not handled properly, it may corrode steel, affect weldability, and induce hydrogen cracks; ( 6) Acetylene is explosive, toxic, and has low safety factor. Calcium carbide consumes a lot of energy and pollutes the environment, but the market demand is large, so China consumes 1 million tons of calcium carbide every year
However, when pentane is used for industrial cutting or welding, it has disadvantages such as low combustion temperature, slow combustion speed, and low calorific value, which is not conducive to industrial production
In order to make pentane overcome the above-mentioned shortcomings so that it can be suitable for use in industrial cutting and welding processes, it is generally by means of adding a combustion synergist to the gas at present, but after the existing combustion synergist is added, there is still a problem that the total calorific value of combustion is not high , The disadvantages of low combustion temperature, slow combustion speed, low combustion efficiency and non-concentrated flame are not enough to replace the application of acetylene in industrial cutting and welding processes

Description

technical field [0001] The invention relates to the technical field of industrial gas synergists, in particular to a combustion synergist of pentane for metal cutting and welding and an application method thereof. Background technique [0002] Industrial gas combustion synergist is a class of fine chemicals that can increase the combustion temperature of industrial gas, accelerate its combustion speed, and improve its calorific value and other properties. It is usually used in metal cutting and welding after mixing with industrial gas. Currently common industrial metal cutting and welding gases mainly include: dissolved acetylene, propane, liquefied petroleum gas and mixed gas, among which dissolved acetylene is the most used, accounting for about 50%. Acetylene and propane have the following disadvantages as cutting and welding industrial gas: (1) Acetylene and propane are flammable, explosive and toxic gases with low safety factor, easy to deposit carbon, and emit black s...
