Description
Technical Field
The invention relates to the technical field of protection of buried objects, in particular to a protection method of unearthed cultural relics.
Background
At present, for cultural relics buried in underground buried objects or ancient cemeteries, due to the complex underground environment and the various soil environments, the cultural relics can be corroded in the underground environment under the action of acidic liquid or alkaline liquid. On the one hand, due to the development of modern industry, acid rain on the surface of the earth flows to the underground, and can have certain destructive effect on underground buried objects and cultural relics. Harmful gases capable of constituting corrosion to cultural relics are mainly acid gases and oxidizing gases. Such as carbon dioxide, sulfur dioxide, hydrogen sulfide, nitrogen dioxide, nitrogen, ozone, and the like. For example, soot falls on the surface of marble and adsorbs SO in the atmosphere2Fe, Mn and the like in the coal dust can be used as catalysts to ensure that SO2By oxidation to SO3，SO3The sulfuric acid is combined with water to synthesize sulfuric acid, which can corrode carbonate stones such as marble and the like, and the chemical reaction formula is as follows:
2SO2+O2→2SO3
2SO3+H2O→H2SO4
H2SO4+CaCO4→CaSO4+H2O+CO2↑
CaSO4+2H2O→CaSO4·2H2the pH value of the O (gypsum) acid rain can be reduced to 4, and the damage to the cultural relics is large. Secondly, in an acidic environment, jade relics and the like containing calcium carbonate are also damaged to a certain extent.
In conclusion, how to reduce the acidity of the underground environment and avoid the corrosion of the acid to the buried objects and cultural relics is an urgent technical problem to be solved.

Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The embodiment provides a method for protecting unearthed cultural relics, which comprises the following steps: adding the reducing metal powder into the surrounding environment of the underground buried object, and keeping the reducing metal powder in the surrounding environment of the underground buried object for a certain time. Wherein the reducing metal is aluminum powder, and the aluminum powder is smaller than 400 meshes.
Aluminum powder and purified water are mixed and then added into the surrounding environment of the underground buried object, and the oxygen content value of the purified water mixed with the aluminum powder is less than or equal to 25 mug/L. The aluminum powder was kept in contact with the surrounding environment of the underground buried object for 0.5 years.
The buried cultural relics are marble cultural relics, and pure water is injected into the surrounding environment of the underground buried cultural relics at intervals of a certain time so as to keep moisture.
Example 2
The embodiment provides a method for protecting unearthed cultural relics, which comprises the following steps: adding the reducing metal powder into the surrounding environment of the underground buried object, and keeping the reducing metal powder in the surrounding environment of the underground buried object for a certain time. Wherein the reducing metal is aluminum powder.
Aluminum powder and purified water are mixed and then added into the surrounding environment of the underground buried object, and the oxygen content value of the purified water mixed with the aluminum powder is less than or equal to 25 mug/L. The aluminium powder is kept in contact with the surroundings of the underground burial for a period of 1 year.
Wherein the buried objects are metallic cultural relics and marble cultural relics. Pure water is injected into the surrounding environment of the underground buried object at certain intervals to keep moisture.
Example 3
The embodiment provides a method for protecting unearthed cultural relics, which comprises the following steps: adding the reducing metal powder into the surrounding environment of the underground buried object, and keeping the reducing metal powder in the surrounding environment of the underground buried object for a certain time. Wherein the reducing metal is aluminum powder.
Aluminum powder and purified water are mixed and then added into the surrounding environment of the underground buried object, and the oxygen content value of the purified water mixed with the aluminum powder is less than or equal to 25 mug/L. The aluminum powder was kept in contact with the surrounding environment of the underground buried object for 1.5 years.
Wherein, the buried cultural relics are bronze wares. Pure water is injected into the surrounding environment of the underground buried object at certain intervals to keep moisture.
The principle of the invention is as follows:
after mixing aluminum powder and purified water, when the aluminum powder is added to the periphery of an underground buried cultural relic, because the environment around the underground is a slightly acidic environment, the aluminum powder can directly react with acid in the slightly acidic environment, and the aluminum powder is oxidized by oxygen to generate aluminum oxide which further reacts with the acid. In a word, no matter how the reaction is carried out, the added aluminum powder consumes oxygen or acid to a certain extent, and corrosion and damage of the oxygen and the acid to the surface of the cultural relic are avoided, for example, the cultural relic is made of marble or carbonate jade, and in an acid environment, the carbonate reacts with the acid to generate carbon dioxide and the like, so that the marble or jade cultural relic is easily corroded by the acid.
In the method of the present invention, the chemical reactions that may occur are:
2Al+3H2SO4＝Al2(SO4)3+3H2
4Al+3O2＝2Al2O3
Al2O3+3H2SO4＝AL2(SO4)3+3H2O。
and in an acid environment, the aluminum powder can perform a complex chemical reaction with acid, so that most of the acid in the soil is consumed, and the corrosion of the acid to cultural relics is avoided.
The method can reduce the corrosion damage of the acid-base environment in the coffin chamber to the cultural relics caused by the infiltration of geology, soil and external environment in the coffin chamber to the greatest extent, and protect the integrity and the aesthetic property of the cultural relics to the greatest extent.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
