Abstract
A noncombustible painted inspection penetrant, the characteristic is its component and weight percentage: the isobutyl Glycine 35-75wt%; the carbonate propylene alcohol 12-40wt%; the blowing agent TSHG9-15wt%; selenium red 4-10wt%. The invention is that the noncombustible painted inspection penetrant, the noncombustible penetrating inspection cleaning liquid and the noncombustible penetrating inspection developer use complementally. The invention can not only achieve inspection assignment, but also prevent burning accident effectively.
Description
Technical field
The present invention relates to the engineering flaw detection, belong to fine chemistry industry prescription and preparation technology, particularly a kind of non-combustion dye check penetrating fluid and preparation method thereof.
Background technology
The employed penetrant flaw detection agent of liquid penetration test that has worldwide occurred at present many kinds of models.But all there is common weakness in they: flammable.
As everyone knows, burning has three fundamentals: flammable material, oxygen and high temperature, if block one of them among the key element, just can avoid burning.The most of compositions of existing dye check agent all are inflammable Organic Ingredients, and do not take the obstruct measure.
For the problem in the site operation that solves the shipbuilding engineering, need to survey defectives such as weld crack.When surveying, all unavoidably there is the naked light of welding, gas cutting one class to exist on every side, at this time adopt the dye-penetrant inspection operation, be easy to breaking out of fire, so must a kind of fire-retardant type dye-penetrant inspection liquid of development.
In the past, at the penetrant flaw detection agent of an other class---in the fluorescent penetrant inspection agent, though " flame retardant type " fluorescent penetration flaw detection liquid also occurred, but just fire-retardant, be not fire fully, if dangerous situation takes place, though the fluorescent penetrant of flame retardant type has certain flameproof effect, act on limited.In addition the fluorescent penetration flaw detection liquid great majority are to use in indoor special place, and comparatively speaking, the place fireproofing installation is more complete.
Different therewith is, the dye check agent that another kind of range of application is extremely wide, internal field, outfield, high-altitude, down-hole etc. many with other work post and the situation of depositing under use, the building site of naked light is arranged as welding, gas cutting, husky mill etc.As carrying out dye-penetrant inspection, necessarily require others to stop work, this is uneconomic on producing.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of non-combustion dye check penetrating fluid and preparation method thereof is provided, it and the fire-retardant type penetration defects detection developer that matches, fire-retardant type permeation flaw detection cleaning fluid constitute one group of fire-retardant type permeation flaw detection reagent.
Make the fire-retardant type penetrating fluid of flaw detection, adopting non-flame properties raw material is the problem of at first expecting, has many solvents not fire really, as water, phenixin, methylene chloride etc.; all there is more shortcoming in they: though water is nontoxic, cheap and easy to get; but the surface tension coefficient of monomer water is big, seepage force is poor, poor to the dissolving power of organic dyestuff, and monomer water is run into metal and also will be got rusty, and does not meet the requirement of making dye penetrant basically; The solvent of dichlorodifluoromethan hydro carbons such as phenixin, liquid properties on the contrary meet the requirement of preparation dye penetrant inspection agent, but they all are high poison, and be bigger to environmental destruction, and some has stopped producing and having banned use of.
The present invention adopts blowing agent TSHG, modified water compound auxiliary agent, the carbon dioxide bubble release agent, and the measure of inorganic, organic mixing powder can accomplish that the length of flame (weighing the index of burning degree) of dye penetrant inspection agent is zero, reaches and does not fire requirement.Hydrate is nontoxic substantially, emits tie water during high temperature earlier, reduces temperature, decomposes and emits carbon dioxide; In a single day bubble release agent is met fire and is heated, and discharges nitrogen immediately.Carbon dioxide, nitrogen all are the gas that does not fire, and they will be applied to, and the dye penetrant inspection agent covers on the workpiece, and itself and the blocking-up of airborne oxygen are isolated.Like this, the oxygen condition in the burning three elements has been removed, and temperature conditions is affected greatly.Even the base solvent of dye check agent has part can burn vapor evolution to peripheral aerial, also be mixed in wherein because of non-flame properties carbon dioxide, nitrogen, watered down the concentration of flammable steam, reduced the possibility of burning.Moreover, water vapor, carbon dioxide, nitrogen, they are principal ingredients of air, nonhazardous does not destroy ecologic environment yet.
Technical scheme of the present invention is as follows:
A kind of non-combustion dye check penetrating fluid, its composition and percentage by weight are as follows:
Material composition wt%
Glycine isobutyl ester 35～75
Carbonate propanediol 12～40
Blowing agent TSHG 9～15
Selenium nitrogen 4～10.
The preparation method of non-combustion dye check penetrating fluid comprises the following steps:
1. select the red raw material of doing of glycine isobutyl ester, carbonate propanediol, blowing agent and selenium nitrogen of chemical pure or the above purity of chemical pure for use;
2. select the percentage by weight of each raw material, and take by weighing each raw material in this ratio;
3. at normal temperatures, 1/10 consumption of each composition of consumption and other that selenium nitrogen is red is put into making beating material cylinder and is mixed, pulls an oar, and beating time is no less than 1 hour, forms slurry;
4. again that other composition is remaining 9/10 consumption and described slurry together add in the reactor, and under the normal temperature, sealing is stirred, and the time is no less than 2 hours;
5. after stirring end,, promptly obtain the penetrating fluid finished product through 200 purpose screen filtrations.
Penetrating fluid finished product up to standard packed into do in the head tank of propellant, make aerosol jar product with nitrogen.
Technique effect of the present invention is as follows:
The supporting use of non-combustion dye check penetrating fluid of the present invention and fire-retardant type permeation flaw detection cleaning fluid (separate case patent application) and fire-retardant type penetration defects detection developer (separate case application invention).Experiment showed, on engineering and can not only finish the flaw detection task, and can prevent effectively that pyrophoricity accident from taking place.The flaw detection agent of the present invention and other kind use that matches though also can finish the flaw detection task, can not prevent the generation of pyrophoricity accident, because permeation flaw detection needs three kinds of reagent, though only having a kind of is fire-retardant type, other is flammable, does not then reach to prevent the purpose of burning.The penetrating fluid finished product is carried out the sensitivity test on the man-made fracture test plate (panel), can detect the crack of 1/10000mm.
The composition and the percentage by weight of described fire-retardant type permeation flaw detection cleaning fluid are as follows:
Feed composition wt%
Glycine isobutyl ester 30-80
Carbonate propanediol 12-40
