Rapid and non-destructive detection device for soluble salt content of cultural relics

Abstract

The invention provides a detection device for rapid and non-destructive detection of the soluble salt content of a cultural relic. The detection device comprises a soft contact layer in contact with the surface of the cultural relic, a transparent sealing box connected with the soft contact layer and used for controlling moisture in contact with the surface of the cultural relic, a vacuuming unitfor controlling the degree of vacuum in the transparent sealing box, a deionized water supply unit for supplying deionized water to the transparent sealing box, and a testing unit for testing the soluble salt content of a solution in the transparent sealing box. A scientific basis is provided for prevention of cultural relic damage caused by too high soluble salt content and further soluble salt removal.

Description

technical field [0001] The invention relates to the field of cultural relics protection, and more specifically relates to a fast and non-destructive detection device for the soluble salt content of cultural relics. Background technique [0002] The splendid civilization of the Chinese nation for thousands of years has left us with many cultural relics that attract worldwide attention, such as stone, ceramic, earth ruins, murals, etc., as well as organic cultural relics such as silk, paper cultural relics, lacquered wood and bamboo ware. It is a priceless non-renewable cultural heritage and historical resource. [0003] These precious historical relics absorb a certain amount of soluble salt solution during the process of burying the soil or contacting the soil, and the dissolution-crystallization of these soluble salt solutions after contacting the atmospheric environment further causes the "crisp powder" of the cultural relics, "Powdering" damage. So for these cultural re...

Problems solved by technology

The paper strip detection method is mainly to gently stick a paper strip soaked in water on the surface of the cultural relics, take it off after a certain period of time, and use ion chromatography to detect the ion concentration of the soaking aqueous solution. In this method, the paper strip soaked in water will bring salt into it. Inside the cultural relics, the salt content on the surface of the cultural relics tested is lower than the actual value; while the micro core sampling method is to take the cultural relic samples with a diameter of about 5mm and a depth of 2mm through drilling holes and bring them back to the laboratory for testing and analysis. Directly cause damage to cultural relics, and due to the inhomogeneity of cultural relics, the drilled part may not represent the test results of the entire sample
