Embodiment 1

[0029] Embodiment 1 A kind of anti-salt damage method for the protection of cultural relics of earthen sites

[0030] This embodiment is a method for preventing salt damage for the protection of cultural relics of earthen ruins. It is carried out according to the following steps: after scraping off the dust and moss on the surface layer of the salt damage crisp powder of cultural relics of earthen ruins, spray evenly on the position containing 200g / L sodium octaborate water-ethanol solution, the volume ratio of solvent water and ethanol is 1:1, every 100cm 2 Spray 100mL of the solution and let it dry naturally; repeat 3 times.

Embodiment 2-4

[0031] Embodiment 2-4 A kind of anti-salt damage method for the protection of cultural relics of earthen sites

[0032] This embodiment is a method for preventing salt damage used in the protection of cultural relics in earthen ruins. Their operation steps are basically the same as in Embodiment 1, and the difference is only in the amount of raw materials and process parameters. See the following table for details:

[0033] Each raw material consumption and process parameter list in the embodiment 2-4 of table 1

[0034]

[0035] Example 5 Application effect experiment (1) Freeze-thaw resistance cycle test and salt suppression effect test

[0036] Set up two groups of simulated samples and mark them as S group (S group is the sodium sulfate soluble salt experimental group) and C group (C group is the sodium chloride soluble salt experimental group), wherein each group is provided with 5 samples, each Each of the groups has one piece without any treatment as a blank sample,...

Embodiment 6

[0059] Embodiment 6 A kind of anti-salt damage method for the protection of cultural relics of earthen sites

[0060] This embodiment is a method for preventing salt damage used for the protection of cultural relics in earthen ruins, and it is carried out according to the following steps:

[0061] S1. After scraping off the dust and moss on the surface of the salt-damaged crispy powder part of the cultural relics of the earthen site, evenly spray the water-ethanol solution containing 100g / L sodium octaborate on the part, and the volume ratio of solvent water and ethanol is 1:1 , per 100cm 2 Spray 60mL of solution, then air dry naturally;

Abstract

The invention discloses a salt damage prevention method for earthen archaeological site cultural relic protection, and belongs to the technical field of cultural relic protection. According to the invention, sodium octaborate is used as a salt inhibitor, and by virtue of the reinforcing functions of Ba(OH)2, H3PO4 and H2C2O4, on the premise of not changing the original appearance of the earthen archaeological site, the soluble salt disease of the earthen archaeological site cultural relics is effectively inhibited, the mechanical strength of the cultural relics is improved, and good water permeability and air permeability of the cultural relics are maintained; and earthen archaeological site is more resistant to disintegration and salt erosion. In addition, by means of the functions of sodium octaborate deinsectization and sterilization, earthen archaeological site cultural relics can be protected against invasion of microorganisms, and therefore multi-aspect protection of the earthenarchaeological site cultural relics is achieved; and the method is simple, easy to operate, low in cost, capable of being used in a large range and good in practicability. The method is suitable for protection of earthen archaeological sites and crisp stone cultural relics.

Description

technical field [0001] The invention belongs to the technical field of cultural relics protection, in particular to a method for preventing salt damage used in the protection of cultural relics in earthen sites. Background technique [0002] At present, my country has a large number of soil sites, such as Banpo Site and Shimao Site, etc. These soil bodies are relatively fragile and are easily threatened by diseases such as brittle alkali, erosion, differentiation, and cracking. These diseases are mainly caused by the salting-out phenomenon of soluble salts. The salting-out phenomenon is due to the migration of soluble salts in the soil to the surface of the ruins with the migration of water. Repeated crystallization expansion, dissolution and shrinkage in the soil make the soil structure constantly loose, and then the soil site will suffer from various degrees of disease after external dynamic geological action. [0003] The Chinese invention patent with the authorized anno...
