Description
Technical field
The present invention relates to a kind of cleaning device and its application method, and in particular to a kind of cleaning device of blank and its use
Method.
Background technology
Remanufacture be " recycling " in the recycling economy advocated of country advanced form.Remanufacture product and ensure quality not
Under conditions of original, its cost only has the 50% of original product, saves the energy 60%, saves material and reaches 70%, Neng Gouxian
Writing reduces the cost of production, and reduces influence of the production process to environment.Since 21st century, Rebuilding engineering by
Step has obtained the attention of national all departments, and ministries and commission under the State Council combine promulgation and issued in succession《The People's Republic of China (PRC) is circulated
Economic promotion method》、《On promoting the opinion of remanufacturing industry development》、《State Council is new on accelerating cultivation and development strategy
The decision of emerging industry》Deng file and law, specification and support have been carried out to Rebuilding engineering, and has established Rebuilding engineering development
Major fields and key unit, the development of Rebuilding engineering at home will be greatly facilitated.
Need repeatedly to carry out dirt different on waste and old parts different degrees of cleaning during remanufacturing, because
This, it is the important procedure during part remanufactures to remanufacture cleaning, is detection piece surface dimensional accuracy, form accuracy, position
The premise of the failure modes such as precision, surface property is put, is the basis that part remanufactures, is had to the quality for remanufacturing product comprehensive
Influence.Cleaning is remanufactured to refer to realize waste and old component surface grease, carbon distribution, oil using cleaning methods such as machinery, physics, chemistry
The removal of paint and the pollutant such as coating, dirt, incrustation scale, rust deposite, and the workpiece surface after cleaning is reached the cleanings of industrial requirements
The process of degree.Conventional physical cleaning technology have immersion liquid cleaning, jet cleaning, ultrasonic wave cleaning, chemical cleaning method have pickling,
Alkali cleaning, fused salt cleaning etc., some advanced cleaning techniques that remanufacture are also appeared in industrial production, as Dry ice cleaning, laser are clear
Wash, ultraviolet cleaning, plasma cleaning etc..Traditional physical cleaning method easy damaged matrix surface, and Chemical cleaning, ultrasonic wave
The methods of cleaning, and produces secondary pollution at easy etched the matrix, particularly with the groove of blind hole type component, blind hole, gap, recessed
The pollutant in the regions such as hole does not wash clean clearly.China remanufactures cleaning technique and many deficiencies be present, and future should seek efficient green
Color cleaning technique, the use of cleansing medium that is poisonous, harmful, inflammable and explosive and having pollution is greatly reduced, reduces environmental pollution.
Supercritical fluid cleaning has obtained the concern of people as a kind of green cleaning technology.
Has document report supercritical CO2Clean the technology and device of parts, CO2Critical value it is low, cleaning bar
Part is not high, but supercritical CO2It is smaller to the solvability of the pollutants such as greasy dirt, carbon distribution, paint or coating, and supercritical CO2Often
It is used in combination with other cleaning methods, complex process.In addition, the cleaning of parts is carried out in closed reactor, parts
It is fixed to be built in reactor, supercritical CO2It can not continuously flow, scouring effect, cleaning efficiency can not be produced to pollutant
Not high, cleaning quality is poor.Patent of invention (CN102211096A) discloses a kind of supercritical water jet cleaning equipment, for silicon
The lossless cleaning of piece, but local supercritical environment is difficult to control, and temperature or pressure divergence can all cause local cleaning environment deviation super
Critical condition, that is, it is changed near critical or high-temperature high pressure water, reduces the physical and chemical performance of supercritical water.In addition, the stagnation temperature of water
Spend (Tc=374 DEG C) and critical pressure (Pc=22.1MPa) it is very high, local supercriticality is formed in silicon chip surface, then is needed more
High temperature and pressure.And water has strong acid and strong base characteristic in the supercritical state, harsh is required to equipment and operating condition.
Therefore, cleaning process energy consumption is higher, it is difficult to realizes the industrialization cleaning of silicon chip.
