Abstract
The invention relates to a method for ultrasonic removal of carbon deposition. According to the technical scheme of the invention, the method for ultrasonic removal of the carbon deposition comprises the following steps: deoiling parts, preparing a carbon deposition removing bath solution, carrying out ultrasonic removal of the carbon deposition, and carrying out hydrochloric acid corrosion. The method for ultrasonic removal of the carbon deposition utilizes the carbon deposition removing bath solution with a special formula, has the advantages of fast carbon deposition removing speed, high quality and easy implementation, and besides reduces the environmental pollution caused by using an ordinary chemical immersion method to remove the carbon deposition.
Description
Technical field
The present invention relates to a kind of carbon removing method, particularly relate to a kind of ultrasonic wave carbon removing method.
Background technology
Carbon distribution is fuel and the product of lubricating oil under high temperature oxidation effect.In combustion chamber, oxygen supply is not enough, fuel and scurry into the lube stock of combustion chamber can not perfect combustion, and produce oil smoke and tar particles, after they and lubricating oil mix, be further oxidized into consistence colloidal liquid, stick to securely on nozzle, and under the continuous effect of high temperature, colloid aggregates into again more complicated polymkeric substance, i.e. carbon distribution.And engine temperature is higher, the carbon distribution of formation is also more firmly tightr, and participant belongs to bonding and closes firmly.Carbon distribution is as unclean in cleaning, will waste fuel oil, and have a strong impact on the work-ing life of engine.
What generally adopt in the market is chemical immersion method carbon remover.Utilize 1%～10% 741 washing composition, soak for a long time, more than generally all will being controlled at 24h.But for some obstinate carbon distributions, cannot thoroughly remove like this, can only lean on local mechanical polishing, but adopt this operation, easily damage again matrix, cause scrapping of part.
Summary of the invention
The invention provides a kind of ultrasonic wave carbon removing method, utilize the carbon remover tank liquor of special formulation, have advantages of that carbon remover speed is fast, quality is high, be easy to realize, reduced general chemistry infusion method carbon remover pollution on the environment simultaneously.
Technical scheme of the present invention is as follows:
A ultrasonic wave carbon removing method, comprises the steps:
(1) by part oil removing: employing acetone is degreaser, and part is immersed in degreaser, at room temperature soak oil removing 20～120 minutes, in air, dry or dry up; Put into 60～80 ℃ of alkali lye and carry out electrochemical deoiling, cleaning oil pollution is clean, then carry out hot water wash and cold wash, clean the alkali lye of piece surface remnants;
(2) make carbon remover tank liquor: carbon remover tank liquor formula is: potassium permanganate 10～35g/L, sodium hydroxide 25～50g/L, sodium dichromate 99 5～10g/L; With 40～60 ℃ of hot water, respectively described potassium permanganate, sodium hydroxide, sodium dichromate 99 are thoroughly dissolved, be placed in the groove with ultrasonic equipment, carbon remover tank liquor is stirred;
(3) ultrasonic wave carbon remover: the part after oil removing is put into described carbon remover tank liquor, control ultrasonic frequency at 20～30kHz, carbon remover tank liquor temperature at 40～60 ℃, every a part of 20～40min upset, until the thorough Ex-all of the carbon of piece surface black, piece surface part presents matrix metal gloss; Part is taken out, with hot water wash and cold wash, the alkali lye that piece surface is residual is thoroughly removed;
(4) hcl corrosion: can form oxide compound because alkali lye reacts with carbon distribution, be attached to piece surface, part is put into hydrochloric acid, the oxide compound of piece surface is removed, when part presents the matrix that has metalluster, the carbon on part is thoroughly cleaned out; Then with water blast gun, rinse part surfaces externally and internally, then put into hot water and clean, then make part rapid drying in air, finally with pressurized air, dry up.
Beneficial effect of the present invention:
1, carbon remover tank liquor formula of the present invention is: potassium permanganate 10～35g/L, sodium hydroxide 25～50g/L, sodium dichromate 99 5～10g/L; Wherein potassium permanganate 10～35g/L and sodium hydroxide 25～50g/L are used in conjunction with and can make the rigid structure generation of carbon surface loosening, and then it is inner to corrode carbon, improves carbon remover speed; Potassium permanganate is first for carbon remover tank liquor formula, carbon remover successful in this area.
2, in carbon remover tank liquor formula of the present invention, sodium dichromate 99 can play the effect of protection part metallic matrix, prevents part excessive erosion.
3, the present invention combines with pharmaceutical chemicals hyperacoustic cavitation effect to the solvency action of carbon distribution, reaches the object of thorough decarbonizing.The carbon on border can be removed or weaken to the high-speed micro-jet that the shock action that ultrasonic vibration produces in liquid and ultrasonic cavitation produce in solid and liquid surface, increase stirring action, accelerate the dissolving of carbon, the chemical dissolution effect of strengthening carbon remover tank liquor to carbon.
4, adopt above-mentioned processing method carbon remover, can be successfully applied to the repairing of engine fuel nozzle.After nozzle burner carbon distribution is removed, surperficial metal luster, nozzle opening air-flow is unobstructed, meets design requirement, can make it recover recycling, has saved production cost, increases work efficiency more than 8 times.
