Cultural relic cleaning device and method

Abstract

The invention relates to a cultural relic cleaning device and method. A gas tank and an air source are connected with the gas inlet end of a gas-liquid mixing pump in a parallel mode through a gas inlet pipeline and an air branch respectively, and a gas control valve and an air valve are arranged on the gas inlet pipeline and the air branch respectively. A cleaning liquid pool and a tap water source are connected with the liquid inlet end of the gas-liquid mixing pump in a parallel mode through a water inlet pipeline and a tap water inlet pipe respectively, and a water control valve and a tap water valve are arranged on the water inlet pipeline and the tap water inlet pipe respectively. The outlet of the gas-liquid mixing pump is connected with the inlet end of a mixing tank through a gas-liquid mixing fluid water inlet pipe, the outlet end of the mixing tank is connected with a water tank aeration head and/or a handheld aeration spray nozzle through a gas-liquid mixing fluid water outlet pipe, and the water tank aeration head is placed in a cleaning water tank. The cultural relic cleaning device and method avoid the damage to brittle cultural relics, enable the cultural relics to be kept in an oxygen-deficient environment all the time in the cleaning process, are high in efficiency, protect the environment, save water, reduce the cleaning cost, and are particularly suitable for cleaning the cultural relics made of brittle materials.

Description

technical field [0001] The invention relates to a cleaning device and cleaning method for cultural relics, which are suitable for cleaning various cultural relics with different textures, and are especially suitable for cleaning the cultural relics with fragile silk fibers, special paper and delicate and complex structures. Background technique [0002] Most of the cultural relics have experienced a long history and are very fragile in texture. Therefore, according to the basic principles of less intervention in the protection of cultural relics and the reversibility of protection and treatment, it is necessary to design suitable cleaning tools and cleaning solutions for different cultural relics. [0003] Traditional cleaning methods mainly include physical cleaning and chemical cleaning. [0004] Chemical cleaning includes: 1) Organic reagents such as acetone, etc. Due to their high volatility and high toxicity, these reagents are harmful to operators and the environment. ...

AI Technical Summary

Problems solved by technology

[0004] Chemical cleaning includes: 1) Organic reagents such as acetone, etc. Due to their high volatility and high toxicity, these reagents are harmful to operators and the environment. Although the effect is acceptable, it is not conducive to long-term development

2) Strong oxidizing reagents such as low-concentration hydrogen peroxide have general cleaning effect and relatively few gases that irritate the human body. Due to their strong oxidizing properties, there may be hidden dangers for low-temperature glazed porcelain and color pigments.

3) Ionic and non-ionic detergen
