Solar nuclear active ion welding gas and preparation method thereof

Abstract

The invention relates to solar nuclear active ion scarfing gas and a preparation method thereof. The invention provides modified scarfing gas, which is prepared from the following raw materials: 1, 20 milliliters of dimethylbenzene; 2, 40 milliliters of petroleum ether or dimethyl ether; 3, 20 milliliters of acetone; 4, 1 gram of colophony; 5, 0.5 gram of ferrocene; 6, 3 kilograms of liquefied petroleum gas; 7, 10 grams of lead or 0.5 gram of potassium permanganate; and 8, 70 milliliters of hydrogen peroxide. Moreover, proper antifreezing agent can also be added according to air temperature conditions. The invention also provides a method for preparing a scarfing gas additive. The additive is added into the liquefied petroleum gas or propane to modify mother liquor, can effectively improve the gasification performance and the activation performance of the mother liquor, change the combustion wavelength and the combustion frequency of the mother liquor in oxygen, improve the combustion performance, and increase the flame temperature, so as to replace acetylene gas to cut and weld metals.

Description

technical field [0001] The invention relates to a solar nuclear active ion welding cutting gas and a preparation method thereof. Background technique [0002] The new industrial gas made by modifying propane gas has been used for metal cutting for a long time. In developed countries such as Europe, America and Japan, new industrial gas has been developed and used on a large scale in the 1970s. In my country in the 1990s In the late 1990s, a series of new gases began to appear one after another. In addition to the earliest application of propane, propylene and petroleum liquefied gas cutting, the research and application of the modification of mother liquor began in 1998. The changes in the formula during the development stage are roughly as follows : [0003] 1. The mother liquor is liquefied petroleum gas or propane, and the additives are all water-soluble additives. The main components are potassium permanganate (catalyst), hydrogen peroxide (hydrogen peroxide, oxygen gener...

Problems solved by technology

[0004] 2. Mixed with water-soluble and oil-soluble additives, the additives are mainly composed of potassium permanganate (catalyst), hydrogen peroxide (hydrogen peroxide, oxygen generator), sodium bicarbonate (baking soda, corrosion inhibitor), ferrocene (combustion-supporting , smoke suppressant), acetone (solvent), ether (gasification, antifreeze), wherein potassium permanganate is dissolved in water, and ferrocene is dissolved in acetone. Since the main active substance is a water-soluble additive, it still cannot overcome the The miscibility of the mother liquor, so the formula of this generation is not scientific

[0005] 3. Use mixed fat additives, mainly including toluene (polymerization inhibitor), cyclohexane (carburization), dodecylbenzoic acid (corrosion inhibitor), glycerin (glycerol, antifreeze agent), ethylene-acrylic acid Ester (low temperature flow improver), barium sulfonate (combustion aid, smoke suppressant); these ingredients have good miscibility with the mother liquor, which can obviously improve the combustion performance of the mother liquor, but the activation and gasification of the mother liquor are not obvious, so the mother liquor Only propane can be used, and it is only suitable for qualified areas, not suitable for large-scale promotion

[0006] 4. Use mixed fat additives and oil-soluble additives. The additives are mainly composed of potassium permanganate (catalyst), hydrogen peroxide (hydrogen peroxide, oxygen generator), acetone (solvent), toluene, xylene (polymerization inhibition), ether ( or petroleum ether, gasification, antifreeze), ferrocene (or barium sulfonate, combustion-supporting, smoke suppressant), wherein potassium permanganate is dissolved in acetone, and added to the cylinder in a certain proportion to let it inside the cylinder Reaction, the formula is more scientific, can effectively solve the problem of miscibility with the mother liquor, improve the combustion characteristics and gasification activation performance of the mother liquor, the application effect is ideal, not only the cutting effect is better than acetylene, but also suitable for welding, but because the catalyst has corrosion to the steel cylinder The effect, and the reaction speed is fast, and the problem of synchronous gasification is not solved, so the product has a short validity period, and the additive will become invalid after being stored for about 7 days, and the process is relatively complicated, so it can only be produced on a small scale and used in a small range

[0017] Each method obviously does not work. Simply increasing the oxygen supply has no obvious effect except increasing oxygen consumption, and it will also cause oxidation of the workpiece; increasing the reaction area requires modification of the tool, such as using propane cutting nozzle and propane nozzles, use a large cutting torch, etc., this can only be used as an auxiliary method and cannot fundamentally solve the problem
