Abstract
The present invention relates to hydrocarbon high energy cutting welding gas prepared from ferrocene, propanone, tetrahydronaphthalene, ether and carburetted hydrogen gas. Through a preparation technology, novel hydrocarbon high energy cutting welding gas is formed. The hydrocarbon high energy cutting welding gas has the characteristics of low cost, high fuel value, high melting speed, high cutting speed, small weld mark, etc. The hydrocarbon high energy cutting welding gas is widely suitable for cutting and welding metal materials in a gas cutting and gas welding mode in industrial production.
Description
The present invention relates to a kind of hydrocarbon compound high-energy cutting-welding gas and preparation method thereof, the invention belongs to the novel high-energy welding and cutting gas of in gas cutting, gas welding field, being invented specifically.
At present in industrial production widespread usage acetylene as combustion gases to metallic substance cutting or gas welding.Significantly exist following problem at the medium-term and long-term acetylene gas that uses of industry: (1) is because so the acetylene combustion calorific value is low slow to the metallic substance burn-off rate, thereby grow, melt and meet about the wide 3mm of reaching man-hour in gas welding or gas cutting process, cause raising (2) a large amount of hydrogen sulfide and phosphuret-(t)ed hydrogen of acetylene combustion generation in the process of gas welding or gas cutting of waste of material and cost that surrounding enviroment are polluted, become the public hazards of environmental protection, be subjected to harmful gases affect to cause unfavorable to human body because the operator is in for a long time in addition, easily cause multiple disease.At existing problem in the prior art, develop a kind of novel hydrocarbon compound high-energy cutting-welding gas and preparation method thereof, be very necessary to overcome existing problem.
In view of existing problem in the prior art, the objective of the invention is to develop that a kind of to have a production cost low, combustion heat value height, burn-off rate is fast, cutting speed in feet per minute is fast, welded seam is little novel hydrocarbon compound high-energy cutting-welding gas and preparation method thereof.
Hydrocarbon compound high-energy cutting-welding gas of the present invention is made up of ferrocene, acetone, tetraline, ether; Each weight percentages of components is: ferrocene 1～3%, acetone 10～30%, tetraline 8～24%, ether 6～18%, carburetted hydrogen gas 40～60%; Hydrocarbon compound high-energy cutting-welding gas of the present invention, wherein tetraline can substitute with naphthane or nitroglycerine; The preparation method of hydrocarbon compound high-energy cutting-welding gas of the present invention, form by the following step: at first with ferrocene, acetone, tetraline, ether, ratio proportioning in raw material in the prescription is injected in the liquefied gas empty bottle, requires to inject carburetted hydrogen gas then in proportion, can use after mixing.
Hydrocarbon compound high-energy cutting-welding gas of the present invention can substitute existing acetylene gas in industrial circle, employing the present invention can realize gas welding or the gas cutting to metallic substance.Characteristics such as the present invention has the calorific value height, and burn-off rate is fast, and cutting speed in feet per minute is fast utilize the present invention to cut, and its melting welding is met little only about 2mm, but the weldering of whenever dried bar meets the economical with materials width to reach about 1 meter.Cost of the present invention in addition is lower than acetylene gas, thereby can reduce production costs about 50%, does not contain hydrogen sulfide, phosphuret-(t)ed hydrogen, nuisanceless so help the health of human body to environment when using owing to the present invention.In sum, widespread use of the present invention will have remarkable economic efficiency and positive social benefit.
Specific embodiments of the invention are as described below, if the hydrocarbon compound high-energy cutting-welding gas that preparation is 100 kilograms, at first getting 2 kilograms of ferrocene, 20 kilograms in acetone, 16 kilograms of tetralines, ether is injected into respectively in the liquefied gas empty bottle for 12 kilograms, reinject after mixing 50 kilograms of carburetted hydrogen gas had both generated hydrocarbon compound high-energy cutting-welding gas.
