Abstract
An energy-saving welding-cutting gas for metals contains liquefied petroleum gas (87-92 wt.%), antioxidizing agent "1076" (1.3-1.7 wt.%), metal passivator (0.6-0.8 wt.%), corrosion inhibitor (0.15-0.25 wt.%), sodium benzoate (0.4-0.6 wt.%), light diesel oil (2.5-3.5 wt.%), hydrogen peroxide (0.55-0.65 wt.%), magnesium chloride (0.7-0.9 wt.%), sodium tetraborate (0.25-0.3 wt.%), and composite catalyst (2-3 wt.%). It can replace acetylene gas and has the advantages of simple preparing process, low cost, no fire return, no toxic gas and no environmental pollution.
Description
The present invention relates to a kind of energy-saving welding-cutting gas for metals, it is the metal welding/cutting gas that substitutes acetylene gas.
The metal current welding all uses acetylene gas, and well-known this gas generation complex process and need consume a large amount of electric energy, and especially its waste residue environmental pollution is gone through evil.So people thirst for having its substitute products to produce.Through 20 databases of ISTIC Research ﹠ Traning Center's retrieval valency, not seeing has document identical with the present invention and patent report.
The object of the present invention is to provide a kind of is that major ingredient is equipped with the energy-saving welding-cutting gas for metals that additives such as 1076 oxidation inhibitor, metal passivator are made in certain proportion with the liquefied petroleum gas (LPG).
The object of the present invention is achieved like this: its composition and weight percent content are: liquefied petroleum gas (LPG): 87-92,1076 oxidation inhibitor: 1.3-1.7, metal passivator: 0.6-0.8, inhibiter: 0.15-0.25, sodium benzoate: 0.4-0.6, solar oil: 2.5-3.5, hydrogen peroxide: 0.55-0.65, magnesium chloride: 0.7-0.9, sodium tetraborate: 0.25-0.35, catalyst compounded: 2-3.
Compare with acetylene gas, the present invention has the following advantages:
1, overcome the liquefied petroleum gas (LPG) doping and can only cut the shortcoming that can not weld,
2, the simple cost of production technique is low, than producing the acetylene gas 62-70% that reduces cost;
3, not tempering, no poison gas does not pollute environment, and is safe and reliable.
Below in conjunction with the component formulation Example in detail the present invention is described in detail:
The present invention is a main ingredient with the liquefied petroleum gas (LPG), is equipped with other additive and is processed into.Its component prescription is represented with following table:
| The component sequence number | 1 | ?2 | 3 | ?4 | ?5 | ?6 |
| Liquefied petroleum gas (LPG) | 90 | ?87 | 92 | ?89 | ?88 | ?91 |
| 1076 oxidation inhibitor | 1.5 | ?2.7 | 1.3 | ?2.2 | ?1.9 | ?1.4 |
| Metal passivator | 0.7 | ?0.6 | 0.8 | ?0.8 | ?0.7 | ?0.7 |
| Inhibiter | 0.2 | ?0.1 | 0.2 | ?0.1 | ?0.2 | ?0.2 |
| Sodium benzoate | 0.5 | ?0.6 | 0.4 | ?0.6 | ?0.5 | ?0.5 |
| Solar oil | 3 | ?3.5 | 1.5 | ?2.5 | ?3 | ?2.5 |
| Hydrogen peroxide | 0.6 | ?0.5 | 0.6 | ?0.5 | ?0.6 | ?0.6 |
| Magnesium chloride | 0.8 | ?0.7 | 0.9 | ?0.8 | ?0.8 | ?0.8 |
| Sodium tetraborate | 0.3 | ?0.2 | 0.2 | ?0.3 | ?0.3 | ?0.3 |
| Catalyst compounded | 2.4 | ?4 | 2 | ?3 | ?4 | ?2 |
1076 oxidation inhibitor of the present invention are by 3,5-di-t-butyl-4 hydroxy phenyl propionic acid, and octadecane fat is formed.Its effect is metalwork oxidation when preventing to weld.Metal passivator adopts N-bigcatkin willow fork N
1-bigcatkin willow hydrazides.Inhibiter adopts the dodecyl phenylformic acid.The effect of hydrogen peroxide is the temperature that adds big flame.Magnesium chloride is used for reducing the melt temperature of metal welding spare as fusing assistant.The effect of sodium tetraborate is the rust dirt of removing metal welding spare.Catalyst compounded effect is decomposition and the carbonization of strengthening after the master is fired.
Production technique of the present invention is, above-mentioned ten kinds of components are mixed, and mixing time is 4 hours, and mixing temperature is a normal temperature.
