Description
Technical field
The present invention relates to a kind of solar nuclear active ion welding gas and preparation method thereof.
Background technology
The infant industry combustion gas that propane flammable gas is made after modification is used for metal cutting and has it long ago, in developed countries such as America and Europe, Japan in the seventies in last century large-scale development and use the infant industry combustion gas just, China in last century the nineties also begin to occur a series of new gas latter stage successively, except that the propane of using the earliest, propylene and oil liquefied gas cutting, the research and the application that mother liquor are begun modification start from 1998, and the variation of filling a prescription in its developmental stage is roughly as follows:
1, mother liquor is oil liquefied gas or propane, additive all is a water-soluble additive, major ingredient is potassium permanganate (catalyzer), hydrogen peroxide (hydrogen peroxide, oxygen-making agent), sodium bicarbonate (sodium bicarbonate, inhibiter), aluminium hydroxide (catalyzer), by a certain percentage, with the laggard row of water dissolution, the active substance that is produced mostly runs off, adding water-soluble additive and mother liquor can not dissolve each other, so modified effect is not obvious, but this trial is the research and development of novel cutting-welding gas has established preliminary theoretical basis, significant.
2, adopt water-soluble and the oil soluble additive mixing, additive mainly is made up of potassium permanganate (catalyzer), hydrogen peroxide (hydrogen peroxide, oxygen-making agent), sodium bicarbonate (sodium bicarbonate, inhibiter), ferrocene (combustion-supporting, smoke suppressor), acetone (solvent), ether (gasification, antifreezing agent), potassium permanganate water dissolution wherein, the ferrocene acetone solution, because main active substances is a water-soluble additive, still can't overcome the mutual solubility with mother liquor, not science so this monobasic is filled a prescription.
3, adopt mixing fat additive, mainly contain toluene (stopper), cyclohexane (carburetting), dodecyl phenylformic acid (inhibiter), glycerine (glycerol, antifreezing agent), ethene one acrylate (cold flow improver), barium sulfonate (combustion-supporting, smoke suppressor); These compositions and mother liquor have good mutual solubility, obviously improve the combustionproperty of mother liquor, but to the activation of mother liquor, pneumatolysis is not obvious, so mother liquor can only be selected propane for use, only are suitable for area with good conditionsi, are not suitable for big area and promote.
4, adopt mixing fat additive to mix with oil soluble additive, additive is mainly by potassium permanganate (catalyzer), hydrogen peroxide (hydrogen peroxide, oxygen-making agent), acetone (solvent), toluene, dimethylbenzene (resistance is poly-), ether (or sherwood oil, gasification, antifreezing agent), ferrocene (or barium sulfonate, combustion-supporting, smoke suppressor) forms, potassium permanganate acetone solution wherein, add steel cylinder by a certain percentage in turn and be allowed to condition at the steel cylinder internal-response, prescription is than science, can effectively solve the problem of dissolving each other with mother liquor, improve the combustioncharacteristics and the gasification activation performance of mother liquor, effect is comparatively desirable, not only cutting effect is better than acetylene, but also be applicable to welding, but because catalyzer has corrosive nature to steel cylinder, and speed of response is very fast, do not have to solve the problem of gasification synchronously, so keeping life is short, depositing 7 days left and right sides additives will lose efficacy, and technology is comparatively complicated, therefore can only small-scale production and use among a small circle.
In fact, the theoretical basis of novel cutting-welding gas all is consistent, be that additive carries out modification to mother liquor, comprise that resistance is poly-, catalysis, activation, carburetting, oxygenation (free state), combustion-supporting etc., the kind of additive is more, and prescription is also made a lot of variety, its core technology be between the additive of selecting for use coordinated and to the degree of functioning of mother liquor modification.That is to say, difference according to the mother liquor composition, the additives ratio of selecting for use so also should be different, so we must be at the composition of domestic raw material, kind and the ratio of selecting additive at ground are arranged, and can not an external blindly prescription complete set indiscriminately imitate, external used mother liquor mainly is the mixed gas that propane, propylene or propane add propylene, and China commonplace be oil liquefied gas, can propane inconvenience, therefore must select suitable additive for use at domestic raw material, just can reach effect preferably.
The same with acetylene, propane also is hydrocarbon polymer, all belongs to hydrocarbons, but because the difference of molecular structure, so very big-difference is arranged on physical properties and chemical property.Acetylene is the simplest alkynes, and molecular formula is C
2H
2Structural formula is H-C ≡ C-H, between C and the C is that triple bond combines, and is made up of a δ key and two mutually perpendicular towering keys, because towering key does not have symmetry axis and overlapping degree littler than δ key, towering key is extremely unstable, very easily destroyed, so towering key is called saturated bond again, chemical property is active, oxidizing fire speed is very fast, and temperature is higher.
Propane is better simply alkane, and molecular formula is C
3H
8, carbon atom bonded hydrogen atom is saturated in the molecule, is also referred to as stable hydrocarbon.In alkane molecule, C-C key and C-H key all is the δ key, is the covalent linkage that combination must be more firm.Chemical property is more stable, torpescence, and the speed of reaction is relatively slow, and the spy is also relatively low when oxidizing fire.
In order to make propane reach the effect of acetylene when the oxidizing fire, for this must carry out modification to propane, though the chemical property of propane is more stable, speed of response is also extremely slow, but C in the molecule-C key and C-H key also can change under the effect of certain temperature, pressure or catalyzer, form less molecule, speed up when oxidizing fire so, temperature also can be higher.
Secondly, acetylene gas is a flammable explosive gas, and no matter highly compressed acetylene be liquid or solid-stately to explode easily when being beaten and colliding.The acetylene water soluble, under 0.1Mpa pressure in the water of the molten equal volume of acetylene, solubleness in acetone is bigger, the acetylene of solvable 20 volumes of the acetone of 1 volume under the normal pressure, under 1.2Mpa pressure, can dissolve the acetylene of 300 volumes, for the safety of transporting and using, usually acetylene is filled under certain pressure in the steel cylinder that into fills with the saturated many property material (as diatomite, granulated dust cork or asbestos) of acetone infiltration, when using acetylene, pressure reduces, acetylene will be separated out, and is to carry out with the gasiform form all the time in the combustion processes.
And being converted into the gasiform form with liquid state, the combustion processes of propane carries out, propane exists with the gasiform form at normal temperatures and pressures, for the ease of storing transportation and using, just must give the propane supercharging, make it to be converted into liquid state from gaseous state, and in the incendiary process, reduce owing to pressure, propane just is converted into gaseous state from liquid state and participates in burning.
Chemical equation from two kinds of substance combustions:
C
2H
2+2.50
2＝2CO
2+H
2O
C
3H
8+5O
2＝3CO
2+4H
2O
An acetylene molecule needs 2.5 oxygen molecule perfect combustions, temperature can reach 3088 ℃, and a propane molecule needs the perfect combustion of 5 oxygen molecules ability, temperature can be up to 3350 ℃, but because the limitation when using the acetylene instrument, propane does not have clean-burning condition, for this reason, if reach the ideal effect, just must improve the combustion conditions of propane: 1, strengthen oxygen-supplying amount.2, increase reaction area.3, accelerate combustionvelocity.4, improve the calorific value of mother liquor.
Each method is obviously unworkable, strengthens oxygen-supplying amount effect and not obvious except increasing oxygen-consumption merely, but also can cause the oxidation of workpiece; Increase reaction area and just must transform instrument, such as using propane cutting torch and propane tip instead, cut welding torch etc. with large size, this can only can not tackle the problem at its root as householder method.Accelerate the combustionvelocity of mother liquor and improve calorific value, just must change the composition of mother liquor, improve the combustioncharacteristics of mother liquor, this method is called modification, this is a kind of feasible, Tong Hang method joins property-modifying additive in the mother liquor exactly in the world, and purpose is that property-modifying additive is dissolved mutually with propane under liquid state, under the gaseous combustion state, change the frequency and the wavelength of flame, activate the main body medium, make it to discharge more energy, and most of energy is reinforced absorption.Suppress flame simultaneously to external irradiation, make flame more concentrated, reach higher temperature.

When winter temperature is lower than 10 ℃, need to add antifreezing agent.The method of adding be earlier with antifreezing agent with 8. mix after interpolation again.
One, cutting
1, selects suitable cutting torch and cutting torch according to steel plate thickness, when using common cutting torch G01-30, G01-100, G01-300, should select than using the bigger slightly cutting torch of equal acetylene gas or using the propane mouth as far as possible, if use equal annular mouth, the most handy gauze enlarges outside one circle mixed gas mouth hole (looping pit) polishing mediation a bit.
2, adjust gaseous tension: adjust between 0.3Mpa-1.0Mpa according to steel plate thickness oxygen, pressure is consistent with acetylene cutting requisite oxygen atmospheric pressure size basically, and the ion welding gas operating pressure is generally 0.03-0.05Mpa.
3, transfer fire: open the cutting torch oxygen switch at first a little, in igniting, slowly open burnt gas switch, light back increase combustion gas earlier and increase oxygen again, gas flow and oxygen flow intersect to be adjusted, notice that the flame root does not leave cutting torch, otherwise extinguish easily during oxygenation, up to adjusting to the shortest internal flame, general flame core length is that 5-8mm is bell mouth shape (but not obvious), color is pearl opal, and is shinny, and profile is clear, flame envelope is blue, rear slightly redly, send " sound of ripping, tittering, frying, burning, etc " sound, if flame too thin and be blue " sound of ripping, tittering, frying, burning, etc " statement shows, illustrate that oxygen is excessive, need to reduce oxygen flow, if flame thin and be blue " sound of ripping, tittering, frying, burning, etc " sound is not obvious, illustrates that combustion gas and oxygen are all less than normal, need to strengthen and intersect and adjust, if the flame flame core has left the rifle mouth, illustrate that combustion gas and oxygen are all excessive, at first reduce the flow of oxygen, reduce the flow of combustion gas again, after flame is regained, strengthen gradually again, intersect and adjust, normal cutting flame is the inclined to one side oxydizing flame of neutral flame, promptly big a little some oxygen on the neutral flame basis can guarantee that like this flame forward line steel is hard, and firepower is violent, the cutting preheating is fast, and otch is neat.In a word, it is oxydizing flame that oxygen and combustion gas ratio are crossed conference generation " roaring flame ", and waste oxygen influences surface quality.Oxygen and combustion gas ratio are too small, and producing " quiet flame " is carbonizing flame, the flame weakness, and cutting speed in feet per minute is slow, and penetrativity is poor.
4, preheating starting: after flame is adjusted, cutting torch is moved on to the steel plate edge, pay special attention to the contact surface of height, angle and the steel plate of preheating, highly preferably flame core just in time touches steel plate, be that the rifle mouth is from the about 4-5mm of steel plate, the edge of flame flame core is attached to steel plate rim openings place, and promptly flame core 1/3 or 1/4 is pressed close to steel plate, and 2/3 or 3/4 in the steel plate outside.If general steel plate (5-30mm), rifle mouth (fireworks) must be vertical with steel plate, and thickness is during greater than 30mm, and cutting torch (fireworks) is towards outer incline 5-10
0, could guarantee that like this preheating is fast, can penetrate steel plate rapidly and guarantee cutting speed in feet per minute.
5, cutting operation: hyperbaric oxygen is once opened foot during starting, penetrates steel plate, should be steady as far as possible during operation, and cutting speed in feet per minute is faster than acetylene.
6, during cutting circular steel, cutting torch and round steel vertical center line are into about 60
0Angle preheating (with flame core outer preheating) after the steel plate burning is red, when discharging hyperbaric oxygen, slowly is adjusted to round steel vertical centre line parallel (promptly vertical with the round steel sea line), and round steel is penetrated.
7, drilling operation: after adjusting flame, flame core is pressed close to steel plate, cutting torch tilts slightly, preheating is carried out to steel plate in outer with flame core, after the steel plate burning is red, cutting torch slowly is adjusted into vertical with steel plate, open hyperbaric oxygen simultaneously steel plate is penetrated, according to job requirements work package is processed again.
8, cutting under water: Qie Ge key is to grasp the opportunity of opening hyperbaric oxygen under water, and the steel plate show is just opened oxygen immediately, otherwise steel plate needs preheating again after being cooled.Because spray rolls, sight line is unclear, needs during preheating cutting torch is tilted into the water, and slowly near steel plate, utilizes sensation and experience, grasps the height and the angle of flame flame core.For effectively shortening warm up time, cutting head (divergent bore nozzle) under the best water.
9, cutting cast iron and stainless steel: because cast iron and stainless steel and general steel plate component and atomic structure is different, when the cutting ordinary steel, carbon atom in the steel plate at high temperature participates in combustion reactions, effect lower cut in the high pressure forward line is neatly smooth, but when cutting cast iron and stainless steel, can only be to utilize high temperature that iron atom is melted, can not form neat forward line, so otch is irregular, can only utilize the forward line that the molten iron of fusing is blown down, the preheating back is opened the limit, forward line and is moved cutting torch, slowly moves forward.
Two, welding
1, according to the thickness situation of weldment, choose suitable welding torch and tip, when using common welding torch H01-2, H01-6, H01-12, H01-20, select tip should use large size tip (or propane mouth) as far as possible, the auger bit of also available φ 1.5 enlarges the mouth hole, to guarantee the mixed gas required area that burns.
2, adjust gaseous tension, oxygen pressure is about 0.2-0.3Mpa generally speaking, needs 0.5-0.6Mpa, the about 0.02-0.05Mpa of combustion gas operating pressure when being used to toast.
3, transfer fire: open oxygen switch at first slightly, open burnt gas switch again, igniting increases combustion gas earlier, increases oxygen again, and combustion gas and oxygen intersect adjustment.The normal about 8-12mm of flame core length (selecting) according to weldment thickness, color be pearl opal, shinny, stable, do not beat, the flame envelope color is a blueness, afterbody is rubescent, does not move swiftly.If flame envelope is thinner, and when being blueness, illustrate that oxygen proportion excessive (oxydizing flame) needs to reduce oxygen flow; combustion gas and oxygen are intersected again and be adjusted to normal flame, if flame envelope is too thick and take on a red color, flame core is oversize; oxygen proportion too small (carbonizing flame) is described, needs to increase oxygen.
4, oxydizing flame: when unnecessary participation incendiary oxygen is arranged in the flame, unnecessary oxygen forms free oxonium ion, the molten bath weld seam is corroded, (profile identification: combustion gas is less than oxygen to make the weld seam oxidation play slag, this moment, flame flame core profile had fairly obvious, but color density is thin, is hollow shape, and sends the violent sound.); Carbonizing flame: when burning, have remaining combustion gas imperfect combustion, unnecessary combustion gas meeting forms carbon compound, long-pending investing on molten bath and the weld seam, make it carburizing, can reduce mother metal machinery plasticity (profile identification: combustion gas is greater than oxygen, this moment some weakness of flame flame core, profile is distant taper shape, though color density is denseer, flame core is not shinny.); Neutral flame: combustion gas and oxygen perfect combustion, be also referred to as reducing flame, purposes is more extensive, be the commonly used best flame of steel to steel welding, but strictly, neutral flame should be the suitable oxygen and the mixed firing flame of gas flow, rather than as long as (profile identification: combustion gas and oxygen proportion are moderate for the mixed firing flame of any flow of combustion gas and oxygen perfect combustion, flame flame core appearance profile is clear, is contrast intensive taper shape, and color density is very strong and shinny.)。
5, after flame is adjusted, the flame flame core is aimed at weld seam, at first preheating steel plate, after treating that steel plate is rubescent, welding wire is shifted near flame core, welding torch and weldment angle are about the 40-50 degree, welding wire and welding torch are about right angle angle, and flame core is aimed at weld seam translation forward always, and welding wire drags backward simultaneously.Note grasp speed and angle, pay special attention to the angle of flame core and weldment simultaneously.If produce the phenomenon that sparks flying off in all directions, illustrate that oxidation is serious, be confirmed to be under the prerequisite of normal welding flame, need flame core is improved flame point and the about 4-6mm of welding seam distance when normally welding, the too high then difficult good molten bath that forms, be difficult for through welding, cross and lowly then can produce oxidation and weld seam is rough.
6, the selection of welding wire: the selection of welding wire should select for use carbon content consistent daytime with the carbon content of weldment, or less than the carbon content of weldment, to guarantee that mechanical property, Chemical Composition conform to welded weldment, generally the torch welding rods fabricated with standard can meet the demands, if there is not torch welding rods fabricated, can select iron wire to replace, but note to select softer iron wire, generally select 14 for use
#Iron wire can guarantee good molten bath and surface smoothness, if galvanized wire can influence the attractive in appearance of weld seam.
7, the welding of non-ferrous metal: because the fusing point of non-ferrous metal is lower than the fusing point of iron, so be easier to welding, adjust flame after, notice that the cooperation of both hands gets final product, speed is also very fast.
8, stainless welding: under normal flame, big a little combustion gas and oxygen flow, method is the same with the welding general steel plate, and is attractive in appearance for what guarantee to weld, needs with stainless steel welding powder water furnishing pasty state weldment to be smeared one time, begins welding after the drying.
Three, cutting torch and cutting torch and weldering distance and tip selects for use

Four, omnibus bar
The used mother liquor of cutting-welding gas is propane or oil liquefied gas, need absorb a large amount of heat energy the gasiform process being converted into from liquid state, temperature can decrease, and the vaporization ability of propane or oil liquefied gas has confidential relation with temperature, the high more vaporization ability of temperature is strong more, temperature is low more, and vaporization ability is weak more.The heat energy that gasification absorbed can only carry out heat exchange by steel cylinder and surrounding environment and obtain, and in order to guarantee fully to carry out heat exchange when envrionment temperature is low, can consider to use the omnibus bar air feed.
The so-called omnibus bar air feed simultaneously that exactly several steel cylinders is connected in parallel, every steel cylinder institute air feed is less comparatively speaking like this, can have adequate time to carry out heat exchange and guarantee to gasify.The way of omnibus bar is simpler, be input in the pipeline after promptly every steel cylinder being reduced pressure by decompression table respectively by pipeline (φ 50-150mm), be adjusted to suitable operating pressure by the total reduction table, also can get final product being adjusted to suitable operating pressure at pipeline exit with a decompression table after the steel cylinder parallel connection.Omnibus bar can be made by oneself also and can buy, and notes the stopping property of pipeline, and gas input channel after reducing pressure is more safer.
The technique effect of realizing is as follows:
The most crucial technology of the sun nuclear civilian welding and cutting fuel gas of worker is exactly to use the fusion principle by the apolegamy of additive, adopt breakthrough prescription, each component efficiently cooperates, additive exists with free state, mother liquor modified active, combustion-supporting, inhibition are finished synchronously, and can be according to the variation of pressure, the auto-control reaction speed, improve the physics and chemistry performance of mother liquor, have obvious advantage aspect wide in the civilian Cutting Length of worker, cutting speed service time, seam.

The civilian welding and cutting fuel gas calorific value of sun nuclear worker is near 2 times of the acetylene gas calorific value, outside the cutting welding function of the comprehensive replaced acetylene gas of decapacitation, can also punching, bevel, cure, rectification, flange, cutting under water, continuous casting connect and cut and the application of the processing such as heat treatment.
5, production technology is simple. Technology maturation, easy to operate, simple and practical, can be used for suitability for industrialized production and family's workshop production; Reach fusion and the effect of the activation of gasifying synchronously according to different geographical, different mother liquors with different weather conditions adjustment prescriptions, be equipped with the normal pressure filling apparatus, can satisfy comprehensively and add the prescription production requirement.
6, instrument is general. Need not change welding torch and cutting and welding torch-tip, fully general with the acetylene gas instrument, save cost, be convenient to promote.
7, the low profit of cost is high. About 400 yuan of every bottle of prices of acetylene cylinder, heavily about 50KG, and meet only heavy 10Kg of the civilian welding and cutting fuel gas steel cylinder of GB17673-1999 national standard sun nuclear worker, about 160 yuan of prices. Standard is dressed up these about 20 yuan/bottle, only 60 yuan of prices, and surpass the operating efficiency of one bottle of acetylene.
8, production and application is pollution-free. As everyone knows, acetylene gas has the black flue dust when igniting, in use can produce pernicious gas, contaminated environment, and its gas itself has toxicity, as sucking a certain amount of gas, can cause the poisoning symptoms such as dizzy in the operation. The civilian welding and cutting fuel gas mother liquor of sun nuclear worker itself is exactly nontoxic clean energy resource, adds fusion activation gasifying agent, can completing combustion in air, and it is pollution-free to environment and human body only to produce C02 and H20.
