Description
Technical field
The present invention relates to water outlet historical relic cleaning technique field, be specifically related to a kind of circulating micro-nano air-bubble of kinetic pump clear
Wash out the method and device of hydrology thing.
Background technology
Historical relic is non-renewable remnants, carries abundant human history cultural information.In very long historical floods,
China outputs a large amount of ware to all over the world.Sea-freight is as a kind of traditional means of transportation, and the amount of having is big, safe and convenient
And the advantage such as freight rate is cheap.But owing to perils of the sea shipwreck event happens occasionally, cause countless export trade ware be retained in boundless and indistinct greatly
Depths, sea.Along with the development of cause of engaging in archaeological studies under water now, a large amount of ancient Chinese ceramics devices are salvaged from ocean.By right
On ship, the restoration and protection research of ware historical relic, can preferably restore Historic original appearance, understands processing technology at that time, science and technology literary composition
The historical informations such as change, commerce and trade.
The historical relics such as major part ocean effluent ceramic, through the length of calcareous thing such as sea water long period of soaking and marine organisms, sea mud etc.
Phase acts on, the hard concretion that tight cementing formation volume is not of uniform size.The situation that these concretions change in extraneous humiture
Under, the historical relic bodies such as the pottery wherein wrapped up will necessarily be produced physical property extruding and destroy, how before guaranteeing historical relic safety
Putting, by these historical relics, from concretion, complete extraction is out, it has also become an extremely urgent difficult problem.Therefore, ocean water outlet is carried out
Ware week body concretion cleaning research, for protection and the preservation of the ware of archaeological excavation water outlet under water, have general
All over and profound significance.But so far, for the removal research of the coagulated material of cultural artifact surface attachment in shipwreck be not yet
System is carried out.
Along with the unearthed water outlet of a large amount of rare cultural relics, companion's and come is heavy and the historical relic's protection of arduousness work.In order to
Properly preserve historical relic, it is necessary to its restoration and protection carrying out necessity is processed.Old pottery and porcelain mending protection technological process includes: environment divides
Analysis, on-site investigation, state estimation, cleaning and descaling, desalting processing, match-place be bonding, repairs defect, reinforces closure, and colour combination is done old etc.
The selection of various technological means and enforcement.
Cleaning is the first step that water outlet historical relic's protection is repaired.Water outlet cultural relic diseases includes the deposition on soluble-salt, surface
Thing, organic dirt etc..Wherein the biological disease on the difficulty soluble salt deposit of cultural artifact surface attachment, surface etc. are more difficult to remove, usually need
Want mechanical cleaning, Chemical cleaning and ultrasonic waves for cleaning.But these methods are while taking out stains, it is also possible to porcelain
Tire glaze produces corrosion, causes than more serious or potential damage.Further, these cleaning methods there is also various shortcoming, such as machine
Tool method cannot meet high cleanliness cleaning requirement, and chemical cleaning method is easily caused environmental pollution, it is thus achieved that cleannes also
The most limited, particularly when dirt composition complexity, it is necessary to select multiple abluent repeatedly to clean and be only possible to meet surface cleanness
Requirement.Hu Dongbo of Peking University et al. have studied the impact on porcelain of the conventional chemical cleaning materials, finds generally,
The abluent that cleansing power is strong, damage the strongest (Hu Dongbo, Zhang Hongyan, the conventional cleaning material impact on porcelain to porcelain
Research, historical relic's protection and archaeology science, 2010,22 (1): 49-59).
Although ultrasonic cleaning process cleaning performance is pretty good, but the cleaning to submicron order dirt grain shows helpless,
The size of rinse bath also limit scope and the 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, the high accuracy being relatively suitable for little scope is cleaned, on a large scale
The occasion effect of seriously corroded is limited.
Therefore, research and develop the cleaning method of the hardest concretion of different diseases on new applicable water outlet historical relic, right
Historical relic carries out efficient lossless cleaning, significant for historical relic restoration and protection and recovery Historic original appearance.
Summary of the invention
It is an object of the invention to, it is provided that the circulating micro-nano air-bubble of a kind of kinetic pump wash out hydrology thing method and
Device.Have developed the cleaning method of the hardest concretion of different diseases on new applicable water outlet historical relic, it is achieved to going out the hydrology
The efficient lossless of thing cleans.
To achieve these goals, the technical solution used in the present invention is as follows:
The method that the circulating micro-nano air-bubble of a kind of kinetic pump washes out hydrology thing, the method is: will by air dissolved pump
Air and water pressurization are mixed to get air-water mixture, and this air-water mixture generates micro-nano gas by micro-nano bubble generator again
Soaked, utilize the micro-nano air-bubble generated that water outlet historical relic is carried out.
Preferably, during by air and water pressurization mixing, air mass flow is less than or equal to 10% with the ratio of discharge.
Preferably, the discharge pressure of described air dissolved pump is 0.2～0.4Mpa.
Preferably, when the micro-nano bubble electrical conductivity of water washing out hydrology thing is constant, terminate clear to water outlet historical relic
Wash.
In technical scheme, by air dissolved pump by air and water pressurization mixing, the air-water mixture of generation leads to again
Cross micro-nano bubble generator and generate micro-nano air-bubble, utilize the efficient interfacial activity of micro-nano bubble, superpower infiltration to make
With and micro-explosion power, weaken historical relic and disease attachment impurity between adhesion, the different diseases attachment on historical relic is shelled
From, thus complete the cleaning of water outlet historical relic.
The present invention also provides for the circulating micro-nano air-bubble of a kind of kinetic pump and washes out the device of hydrology thing, this device bag
Include: pump priming funnel, pump priming valve, pump priming water pot, air dissolved pump, air needle valve, air flow sensor, check-valves, pressure pass
