Description
Technical field
The present invention relates to water outlet historical relic cleaning technique fields, and in particular to a kind of circulating micro-nano air-bubble of kinetic pump is clear
Wash out the method and device of hydrology object.
Background technology
Historical relic is non-renewable remnants, carries abundant human history cultural information.In very long historical floods,
China to outputing a large amount of wares all over the world.Sea-freight has amount big, safe and convenient as a kind of traditional means of transportation
And the advantages such as freight rate is cheap.But since perils of the sea shipwreck event happens occasionally, countless export trade wares are caused to be retained in boundless and indistinct big
Extra large depths.With the development of current underwater archaeology cause, a large amount of ancient Chinese ceramics devices are salvaged from ocean.By right
The restoration and protection research of ware historical relic, can preferably restore Historic original appearance on ship, and manufacture craft, the science and technology understood at that time is literary
The historical informations such as change, commerce and trade.
The historical relics such as most of ocean effluent ceramic, the length through the calcareous object such as seawater long period of soaking and marine organisms, ooze
Phase acts on, close cementing formation volume hard coagulation not of uniform size.These coagulations are the case where extraneous humiture changes
Under, physical extrudings will necessarily be generated to historical relics ontologies such as the ceramics that wherein wrap up and destroyed, how before ensuring that historical relic is safe
It puts, by these historical relics, complete extraction comes out from coagulation, it has also become extremely urgent problem.Therefore, carry out ocean water outlet
Ware week body coagulation cleaning research, for underwater archaeological excavation be discharged ware protection and preservation, have it is general
All over and profound significance.However so far, the removal of the coagulated material adhered to for cultural artifact surface in shipwreck is studied
System is carried out.
With the unearthed water outlet of a large amount of rare cultural relics, accompanied by is heavy and arduous historical relic's protection work.In order to
Properly preserve historical relic, it is necessary to necessary restoration and protection processing is carried out to it.Old pottery and porcelain mending protection technological process include：Environment point
Analysis, on-site investigation, status assessment, cleaning and descaling, desalting processing, match-place bonding, repairing defect, reinforce closure, colour combination is done old etc.
The selection and implementation of various technological means.
Cleaning is to be discharged the first step of historical relic's protection reparation.Water outlet cultural relic diseases include soluble-salt, surface deposition
Object, organic dirt etc..The biological disease of indissoluble salt deposit, surface that wherein cultural artifact surface adheres to etc. is more difficult to remove, usually needs
Want mechanical cleaning, chemical cleaning and ultrasonic cleaning.However these methods are while taking out stains, it is also possible to porcelain
Tire glaze generates corrosion, causes than more serious or potential damage.Also, there is also various shortcomings, such as machine for these cleaning methods
Tool method cannot be satisfied high cleanliness cleaning requirement, and chemical cleaning method is easy to cause environmental pollution, the cleannes of acquisition
It is very limited, especially when dirt composition complexity, it is necessary to select a variety of cleaning agents to clean repeatedly and be likely to meet surface cleanness
Requirement.Hu Dongbo of Peking University et al. has studied influence of the common chemical cleaning materials to porcelain, finds under normal circumstances,
The strong cleaning agent of cleaning ability, also very strong to the damage of porcelain (Hu Dongbo, Zhang Hongyan commonly use influence of the cleaning material to porcelain
Research, historical relic's protection and archaeology science, 2010,22 (1):49-59).
Although ultrasonic cleaning process cleaning performance is pretty good, show helpless to the cleaning of submicron order dirt grain,
The size of rinse bath also limits the range and complexity of cleaning object simultaneously, and the historical relic after cleaning needs rapid draing
Also it is a great problem.And the laser cleaning technique occurred in recent years, relatively it is suitble to small-scale high-precision cleaning, for a wide range of
The occasion effect of seriously corroded is limited.
Therefore, the cleaning method that different diseases on new suitable water outlet historical relic are especially hard coagulation is researched and developed, it is right
Historical relic carries out efficient lossless cleaning, is of great significance for historical relic restoration and protection and recovery Historic original appearance.
Invention content
The object of the present invention is to provide a kind of circulating micro-nano air-bubble of kinetic pump wash out hydrology object method and
Device.The cleaning method that different diseases on new suitable water outlet historical relic are especially hard coagulation is had developed, is realized to going out the hydrology
