Abstract
The invention discloses a mixed welding and cutting gas, comprising the following ingredients by weight percent: 94%-96% of liquefied petroleum gas or natural gas or propane gas, 0.6%-1.8% of alcohol, 1.6%-2.9% of n-butyl alcohol, 0.09%-0.6% of ferrocene, and 0.4%-2.1% of petroleum ether. The mixed welding and cutting gas takes natural gas or propane gas or liquefied petroleum gas as a basic master batch and a certain amount of a synergist is added to the basic master material, thus the mixed welding and cutting gas has the advantages of high temperature, high combustion value, full combustion, regular flame shape and the like, is easy to control and is an ideal substitute for acetylene gas.
Description
Technical field
The present invention relates to a kind of mix welding gas body that is used for metal welding.
Background technology
The gas that is used for metal welding traditional in the industry adopts acetylene gas mostly, but acetylene gas cost height, explosive, safety coefficient is low, production process both consumed energy power consumption, contaminate environment again.Acetylene is higher owing to carbon content, thus in use wayward with the blending ratio of oxygen, being easy to generate black smoke, state of combustion instability, temperature of combustion are also unstable.Exist a large amount of covalent linkage in the molecular structure of acetylene, these covalent linkage formation molecular grouping of reuniting mutually makes acetylene gas fully not burn, and influences result of use, and metal welding is produced very big disadvantageous effect.Therefore, acetylene gas all exists many defectives or hidden danger at aspects such as production, storage, transportation, use, environmental protection, price and welding quality, and along with the progress of development of productivity and society, the mankind more and more pay attention to environmental protection, energy-conservation, safety, efficient.Thereby alternative acetylene gas becomes the inexorable trend of era development.
Summary of the invention
The technical problem to be solved in the present invention provides the mix welding gas body that a kind of alternative acetylene gas is used for metal welding.
For solving the problems of the technologies described above, the part by weight of each moiety of the present invention is: alkanes gas 94%-96%, methyl alcohol 0.6%-1.8%, propyl carbinol 1.6%-2.9%, ferrocene 0.09-0.6%, sherwood oil 0.4%-2.1%.
As improvement of the present invention, the part by weight of each moiety is: liquefied petroleum gas (LPG) or Sweet natural gas or propane flammable gas 94%-96%, methyl alcohol 0.7%-1.7%, propyl carbinol 1.8%-2.8%, ferrocene 0.1-0.5%, sherwood oil 0.5%-2%.
Described alkanes gas is liquefied petroleum gas (LPG) or Sweet natural gas or propane flammable gas.
Mix welding gas body of the present invention is basic masterbatch with Sweet natural gas or propane flammable gas or liquefied petroleum gas (LPG), adds an amount of synergistic agent again, have that temperature height, fuel value are big, burning fully, characteristics such as flame profile is regular, easy to control.Not only on performance, can substitute acetylene fully, also have the not available remarkable advantage of acetylene:
1, cost is low, only is about 30% of acetylene gas, and also conserve oxygen is more than 20%.
2, flame is concentrated the temperature height, and oxygen-flame temperature reaches as high as 3400 ℃, and welding speed is faster more than 30% than using acetylene gas, and welding is effective, cuts smooth, dross not, saves time, laborsaving.
3, use does not have black smoke, not tempering, not detonation, and sufficient combustion does not produce phosphide, sulfide etc., and is pollution-free to atmosphere.
Synergistic agent of the present invention mainly is made up of by certain component methyl alcohol, propyl carbinol, ferrocene, sherwood oil.Formulation of synergist is reasonable, and the each component coordinated can be brought into play following effect: combustion-supporting, resistance is poly-, catalysis, gasification synchronously, carburetting oxygenation, the wavelength that improves flame and frequency etc.Wherein: propyl carbinol, sherwood oil, methyl alcohol are combined except energy carburetting oxygenation, can also chop the long carbon bond molecular chain in the alkanes gas off, stop molecule to be reunited, make its molecular structure very little and even, increase its vaporization ability, reduce mother liquor residual in steel cylinder, improve the wavelength and the frequency of flame.Effects such as that ferrocene has is combustion-supporting, smoke elimination, antiknock, increase combustion speed impel full combustion of fuel.
