Description
Technical field
The invention belongs to hardware manufacturing industry technical field, be specifically related to a kind of ultrasonic cleaning process being applicable to steel carbon surface.
Background technology
Cleaning refers to the liquid and solid pollutant of removing surface of the work, makes the cleanliness factor that surface of the work reaches certain.Cleaning is also one very important middle aided process in heat treatment production process.Allly to add through machine, workpiece before heat treatment all should carry out.Otherwise the greasy dirt etc. on the forward and backward surface of the work of heat treatment directly enters heating volatilization and burning in stove, and easily cause workshop air to pollute, workpieces surface condition is also bad, even affects thermal treatment quality, particularly to thermo-chemical treatment and vacuum heat.Cleaning can improve heat treatment production efficiency and thermal treatment quality, the environmental protection relevant with heat treatment, and cleaning belongs to clean heat treatment category.
Ultrasonic Cleaning is mainly used in the higher workpiece of cleaning requirement, especially through the workpiece of Precision Machining, complex geometry, as the aperture on workpiece, deep hole, blind hole and groove etc., can obtain good cleaning performance.Supporting aqueous cleaning agent should under low concentration, and temperature is no more than 60 DEG C, still has stronger cleansing power, not corroding metal, the easy rinsing of low bubble.
According to phosphorus content number, generally carbon steel can be divided into high-carbon steel, medium carbon steel and mild steel three class.The intensity of its medium and high carbon steel is good, poor toughness, so mechanical strength is little, easily ruptures, the material in uncomfortable cooperation machinery and some fields, and life medium and high carbon steel is often used as the material of making frying pan; The good toughness of mild steel, but intensity is low, is often made into iron wire and uses; If accumulate in the equipment manufactured by carbon steel or attachment residual oil, reasonably clean with regard to needs.But the most alkalescence of oil-removing cleaning agent is in the past comparatively strong, and also need the condition by high temperature, such cleaning agent has very large loss to resource, the energy, and easily causes security incident, causes environmental pollution.Development of new take surfactant as the water system residual oil carbon steel cleaning agent of main wash composition, can efficient, safety, environmental protection removing steel surface residual oil, all there is realistic meaning from the angle of economy, safety and environmental protection.
CN91109760.0, the application for a patent for invention that name is called " water-soluble metal cleaning liquor ", this cleaning fluid take water as solvent, adds emulsifying agent dodecyl sodium sulfate, OP-10; Antirust agent penta sodium pentachlorophenate, Sodium Benzoate, natrium nitrosum; Cleaning agent triethanolamine, polyethylene glycol, ethanol, phosphoric acid are formulated, and it can be used for the cleaning of various steel, cast iron product.But it is many that shortcoming is foam, and conductance is low, general needs heats use, is not suitable for Ultrasonic Cleaning.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of ultrasonic cleaning process being applicable to steel carbon surface.Achieve the on-line cleaning of steel carbon workpiece and Assembly part, improve the automatization level of workpiece cleaning, improve cleaning efficiency, reduce the labour intensity of workman, improve working environment.
In order to realize foregoing invention object, the present invention adopts following technical scheme:
Be applicable to a ultrasonic cleaning process for steel carbon surface, it is characterized in that: processing step is as follows:
1) prerinse
Employing hot dipping is washed or the pollutant on workpiece softens, is separated, dissolves by the method for hydro-peening, and alleviates the load of lower road matting.
2) slightly wash
Under the effect of aqueous cleaning agent, the dirt of surface of the work is peeled off and is come off by Ultrasonic Cleaning, simultaneously also can by oleaginous dirt decomposition, emulsification.
Preferably, cold rinsing: utilize the water purification of flowing to come off but still floating wash dirt is clean on the surface of the workpiece.
3) fine purifiation
Adopt ultrasonic rinsing, with pure water wash away surface of the work the cleansing medium that remains;
4) high pressure shower
Adopt comprehensive mode from top to bottom to carry out High Pressure Pure Water injection, to rinse the pollution medium in small blind hole and gap, adopt hot-air seasoning;
The composition and ratio of described aqueous cleaning agent is as follows:
Surfactant KE-1 0.8-1.2 g/l
Surfactant A ES 1.5-2.5 g/l
Surfactant NP 7 2.0-2.5 g/l
Surfactant NP-10 2.2-2.6 g/l
Builder 0.5-0.6 g/l
Composite corrosion inhibitor 0.8-1 g/l
Solvent is water.
The screening and application of surfactant is the key of steel carbon surface aqueous cleaning agent.The present invention selects surfactant KE-1, AES, NP-7 and NP-10 can reduce the surface tension of system, effectively can promote wetting, the infiltration of steel carbon surface greasy dirt, emulsification and dispersion, be cleaned up by steel carbon surface greasy dirt.Act on by hyperacoustic " cavitation ", by cleaning agent working solution component rapid permeability between greasy dirt and metal, greasy dirt is made to peel off rapidly steel carbon surface, peel off rear surface activating agent by grease emulsifying, under hyperacoustic effect, grease broken up and be uniformly distributed in system, improve the oil removing performance of aqueous cleaning agent highly.
On the other hand, due in the functional group of surfactant KE-1, AES, NP-7 and NP-10 with multiple-limb branched structure, for the surfactant of linear chain structure, its obstruction discharge opeing on liquid film surface and " reparation " effect reduce greatly, foam stability weakens, and after therefore bubbling, lather collapse must than comparatively fast.They are composite, good froth breaking and cleaning performance can be reached, meet the requirement of cleaning.
Preferably, described builder is the one or more kinds of combinations in sodium phosphate trimer, 4A zeolite and disodium edta.
Preferably, described composite corrosion inhibitor is that polyethers and imidazoline are composite.
Further preferably, the composite mass ratio of described polyethers and imidazoline is 1:1.
Corrosion inhibiter polyethers and imidazoline are attracted to metal surface through chemisorbed process, and itself forms one deck film closely, or form one deck film closely after reacting with metal ion, therefore corrosion mitigating effect is good.When its addition is 0.6 g/l, minimum rate of corrosion can reach 0.3%.
Preferably, the mass fraction of described cleaning agent cleaning performance when 2%-3% is best.
Ultrasonic Cleaning vibration frequency range of the present invention is at 60 ~ 120 kHz, and power density is set in 0.5-0.8W/C.Frequency can not higher than 120 kHz, otherwise shortened wavelengths, cavitation weakens on the contrary, thus reduces cleaning efficiency.
Cleaning temperature of the present invention is 50-60 DEG C.
Hot-air seasoning of the present invention, refers at 90-110 DEG C, dries 3-10min.
Beneficial effect of the present invention is:
1, the dirt-removing power of this technique is strong, and residual oil degreasing rate can reach more than 99.5%, and rustless property is good.
2, achieve the on-line cleaning of steel carbon workpiece and Assembly part, improve the automatization level of workpiece cleaning, improve cleaning efficiency, reduce the labour intensity of workman, improve working environment.
