Device for strengthening weathered stone cultural relics through activating calcium hydroxide by low-temperature plasma in carbon dioxide atmosphere and method

Abstract

The invention provides a device for strengthening weathered stone cultural relics through activating calcium hydroxide by low-temperature plasma in a carbon dioxide atmosphere and a method. Accordingto the device and the method, setting forth from low-temperature plasma physics and cultural relic preservation principles, a low-temperature plasma technology is applied to the field of preservationof cultural relics, particularly the field of strengthening the weathered stone cultural relics through activating the calcium hydroxide. According to the device and the method, the calcium hydroxideis activated and strengthened through introducing a low-temperature plasma source of carbon dioxide gas, the carbonization and precipitation of the calcium hydroxide can be achieved in 1min to 2min, and the action of strengthening the weathered stone cultural relics is exerted, so that the device and the method have the characteristics of safety, high efficiency, nondestructiveness and no side effect.

Description

technical field [0001] The invention relates to the field of cultural relics protection, in particular to a device and method for strengthening weathered stone cultural relics by activating calcium hydroxide with low-temperature plasma in a carbon dioxide atmosphere. Background technique [0002] At present, the materials used for the reinforcement of weathered stone cultural relics mainly include inorganic materials, organic materials, and organic-inorganic composite materials. Among them, although organic materials have better short-term reinforcement effects, such materials will become brittle and yellow after long-term aging, and their mechanical properties will decline. At the same time, because the film formed in the cultural relics is airtight, the surface of the cultural relics will eventually swell, pulverize or even fall off. In short, the compatibility of such materials is poor. Inorganic materials represented by calcium hydroxide have been extensively studied i...

AI Technical Summary

Problems solved by technology

However, the traditional method of strengthening stone cultural relics with calcium hydroxide also has disadvantages such as slow carbonization speed and low efficiency, which greatly restricts this reinforcement method.
