Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, a kind of gas synergist is provided, industrial combustion gas with synergistic agent production of the present invention has good incendivity, security, the feature of environmental protection and very high combustion flame temperature, compare with acetylene gas, it is not easy to blast, store, transport, use and link such as management more convenient and safe, non-environmental-pollution not only, and it is harmless to the person's of manipulating health, preheating and cutting speed in feet per minute are fast, the welded seam quality is good, and oxygen consumption is few, has improved work efficiency effectively and has reduced cost.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of gas synergist of the present invention, described gas synergist is formed by the feedstock production that following weight part is equipped with: turps 20-30 part, acetone 20-30 part, butylacetate 15-18 part, ferrocene 1-3 part, tween-80 8-10 part, Diethylene Glycol 8-12 part, propyl carbinol 10-15 part.
Preferably, gas synergist of the present invention is formed by the feedstock production that following weight part is equipped with: 26 parts in turps, 25 parts in acetone, 16 parts of butylacetates, 2 parts of ferrocene, 9 parts of tween-80s, 10 parts of Diethylene Glycols, 12 parts of propyl carbinols.
Turps has another name called fuel-economizing, gum turpentine.Colourless have special odor to dark-brown liquid, volatile, and ethanol, ether dissolve each other.Be used as solvent among the present invention.
Acetone has another name called Ketene dimethyl, colourless liquid.56.2 ℃ of boiling points are inflammable, volatile, and little fragrance flavor is arranged.Can with immiscible organic solvents such as water, methyl alcohol, chloroform.Can dissolve grease.Be used as solubilizing agent among the present invention.
Butylacetate is clarified little fragrant flammable liquid, and 126.3 ℃ of boiling points are dissolved in ethanol, ether, benzene etc., are used as synergistic agent among the present invention.
Ferrocene, molten some 172-174 ℃, be dissolved in alcohol slightly, be dissolved in the catenanes organic solvent, be soluble in aromatic hydrocarbons, common organic solvents there is katalysis, be used as catalyzer among the present invention.
Tween-80 ℃ has performances such as emulsification, dispersion, wetting, solubilising, infiltration, is used as emulsifying agent among the present invention.
Diethylene Glycol, butyl ether, colourless liquid, little tool butanols smell, 230.4 ℃ of boiling points are with water, oils and other immiscible organic solvents.Make synergistic agent among the present invention.
Propyl carbinol, colourless liquid has smells of wine, and 117.7 ℃ of boiling points are dissolved in multiple organic compound.Its steam and air form explosive mixture.Be used as ignition dope among the present invention.
Advantage of the present invention is:
Scientific formulation of the present invention is mixed with mother-qi (propane or oil liquefied gas, Sweet natural gas) by weight the 0.5%-0.6% volume with synergistic agent of the present invention, can produce the energy-saving environmental protection industrial combustion gas.With the energy-saving environmental protection industrial combustion gas of synergistic agent production of the present invention, broken through the carbonization welding and do not passed a test and two slow big technical barriers of preheating, strengthened the activity of industrial combustion gas, about temperature 500 degree of raising main body medium were spent to 700, major advantage had:
1. advanced: broken through the technical barrier of global function replaced acetylene, flame temperature surpasses acetylene, and performance occupies the top standard, has created the theoretical mistaken ideas that liquefied petroleum gas (LPG) can not be used for the carbon steel fusion welding.
2. economical: cost reduces about 50% than acetylene gas, the cost of its steel cylinder is 1/5 of an acetylene, bottle heavily is 1/3 of an acetylene cylinder, save freight charges 2/3, the switching rate of 15kg steel cylinder is 1/5 of an acetylene, and work efficiency is higher than acetylene far away, and cutting slit width is narrower by 5% than acetylene, save steel, cutting and chewing the life-span is 3 times of acetylene.As if 100 bottles/day of the energy-saving environmental protection industrial combustion gas replaced acetylenes of producing with synergistic agent of the present invention, year can be saved about 1,800,000 yuan.
3. environmental protection: the energy-saving environmental protection industrial combustion gas of synergistic agent production of the present invention belongs to green gases, synergistic agent is nontoxic, pollution-free, does not produce obnoxious flavour, no black smoke in the combustion processes, do not damage HUMAN HEALTH, meet TJ36-79 (Design of Industrial Enterprises hygienic standard) fully
4. safety: the energy-saving environmental protection industrial Gas Explosion Limits 2.5-12.1 (V/V) that produces with synergistic agent of the present invention, be 1/8 of acetylene only, burning-point is higher than acetylene, and aerial combustionvelocity is 1/3 of an acetylene, pressure only is about 1/4 of acetylene, and not tempering.
Prove that according to the examining report of national authority mechanism and user's actual use " the energy-saving environmental protection industrial combustion gas with synergistic agent production of the present invention possesses following advantage: every technology index is equal to and is better than acetylene gas.
(1) safety, not tempering, its limits of explosion scope 2.5～12.1%.
(2) efficient, flame temperature is higher than, cutting faster than acetylene acetylene gas warm up time and punching all is better than acetylene.
(3) good, good, the limit of not collapsing of cutting smooth finish of cutting quality, few, the easy-clear of dross.
(4) the good fusion penetration of welding fabrication, porous, weld seam tensile strength reach the disconnected mother metal of 410Rmlv/mm, and crooked (just carrying on the back) curved 180 ° of equal flawlesses and welding lack.
(5) energy-conservation, price comprehensively consumes pneumatolytic, and this is lower by about 50% than acetylene gas.
(6) energy-saving environmental protection industrial combustion gas cutting and the welding with synergistic agent production of the present invention reaches the acetylene effect, is better than domestic like product, is energy-conservation a, consumption reduction, high-quality, environmental protection, safe, practical good product.One bottle of 15kg for preparing can substitute the acetylene gas of 5 bottles of 5kg with the energy-saving environmental protection industrial combustion gas of synergistic agent production of the present invention.Experimental data shows, add in the propane flammable gas behind the synergistic agent of the present invention gas consumption by 350 liters/time drop to 150 liters/time, save combustion gas 57%, the oxygen consumption by 4300 liters/time drop to 3350 liters/time, save oxygen 22%, by 3500 yuan of calculating of combustion gas per ton, deduction synergistic agent expense can also be saved more than 500 yuan.
Industrial combustion gas with synergistic agent production of the present invention has good incendivity, security, the feature of environmental protection and very high combustion flame temperature, compare with acetylene gas, it is not easy to blast, store, transport, use and link such as management more convenient and safe, non-environmental-pollution not only, and harmless to the person's of manipulating health, preheating and cutting speed in feet per minute are fast, the welded seam quality is good, and oxygen consumption is few, has improved work efficiency effectively and has reduced cost.
