Problems solved by technology

[0005] However, at present, these desalination technologies are all contact methods, which are likely to cause varying degrees of damage to cultural relics, especially fragile cultural relics, during the process of contact, soaking and wrapping
Therefore, it is difficult to apply it to the research of cultural relics protection on a large scale
[0006] Existing data show that there is no report on non-contact salt control research and technology in the field of cultural relics protection

Embodiment 1

[0042] Such as figure 2 As shown, measure 100ml of deionized water, add it into the atomization cup of the ultrasonic nebulizer, and adjust the distance between the nozzle 201 of the nebulizer and the simulated cultural relic sample 202 to be 5.0cm. The optimal distance is that the surface of the simulated cultural relic sample has no obvious condensed water droplets, turn on the atomizer, and atomize the simulated cultural relic sample at an atomization rate of 1.5ml / min. The concentration of salt on the surface of the simulated cultural relic samples decreased continuously with the adsorption and migration of the atomized water. The atomization treatment time was 5.0 hours, and the depth of the atomized water vapor infiltrating into the simulated cultural relic samples was 2.0 cm.

Embodiment 2

[0044] Such as image 3 As shown, first measure 100ml of deionized water, put it in a 200ml beaker, then measure 0.1% (vol%) wetting agent ethanol 305, pour it into deionized water, mix thoroughly with a magnetic stirrer, and mix Add the liquid into the atomization cup of the ultrasonic nebulizer, adjust the distance between the nozzle 301 of the nebulizer and the simulated cultural relic sample 302 to about 5.0cm, the best distance is that there is no obvious condensed water droplets on the surface of the simulated cultural relic sample, and turn on the atomization The device is used to atomize the cultural relics simulation sample at an atomization rate of about 1.5ml / min. The atomized water vapor 303 and condensed water 304 carrying soluble salts migrate from the surface of the cultural relics simulation sample to the inside, so that the concentration of salt on the surface of the cultural relics simulation sample With the absorption and migration of atomized water, it decr...

Embodiment 3

[0046] First, the operation is the same as in Example 2. After 2.0 hours of atomization treatment, change the atomization cup, then measure 100ml of deionized water, place it in a 200ml beaker, then measure 1.0% (vol%) curing agent PS, pour it into After fully mixing with a magnetic stirrer in deionized water, add the mixed liquid into the atomization cup of the ultrasonic nebulizer, and adjust the distance between the nozzle of the nebulizer and the simulated sample of cultural relics to be about 5.0cm. There are no obvious condensed water droplets on the surface of the simulated sample. Turn on the atomizer and atomize the simulated cultural relic sample at an atomization rate of about 1.5ml / min. The atomized water vapor and condensed water carrying soluble salt will flow from the surface of the simulated cultural relic sample to the inside Migration, so that the concentration of salt on the surface of the simulated sample of cultural relics decreases continuously with the ad...

Abstract

The invention relates to an atomizing vapor salt controlling technology. The technology comprises the following steps: putting water-based liquid into an atomizer; adjusting a distance between a nozzle of the atomizer and samples of cultural relics to be 5.0 cm to 20.0 cm, and atomizing the samples of cultural relics for 1.0 hours to 24 hours at an atomization rate of 1.0 ml / minute to 5.0 ml / minute to ensure that the atomized water vapor carrying soluble salt on the surfaces of the cultural relics to migrate toward the inner part of the cultural relics. According to the technology disclosed by the invention, different water-based atomizing vapor salt controlling protection technologies and plans can be provided according to the cultural relics of different materials, the current situations of the cultural relics, the categories and contents of salt in the cultural relics and environment conditions in which the cultural relics are located.

Description

technical field [0001] The invention belongs to the technical field of water and salt migration regulation for cultural relics protection, and specifically relates to an atomized steam salt control technology, which is used to regulate the behavior of water and salt migration and crystallization in cultural relics, especially extremely fragile silicate cultural relics (including murals, The migration of water and salt in grottoes, earthen ruins, ceramics, etc.). Background technique [0002] Cultural heritage is an extremely important cultural element that distinguishes China from other countries. It is an important carrier of China's excellent traditional culture and carries the self-confidence of Chinese culture with a history of more than 5,000 years of civilization inheritance. Cultural self-confidence is the value of a nation and a country to its own culture. fully affirmed and actively practiced, and has firm confidence in the vitality of its culture. [0003] However...
