Ruins/cultural relics cleaning, surface repair and cleaning
Time：2023-09-05 Category：【Industry dynamics】Read：239
The preservation status of cultural relics varies, including unearthed artifacts with various calcium and silica deposits, repaired artifacts with difficult-to-remove adhesives such as epoxy resin, and accumulated grease and dirt on heritage artifacts. In the process of cleaning cultural relics, aged epoxy resin is often the most difficult to remove, as it has strong adhesion, chemical stability, high strength, and low reversibility. Multiple approaches are needed to remove such substances, but many of the reagents used are highly toxic. Therefore, restorers have been seeking more environmentally friendly and convenient cleaning methods to improve the overall environmental friendliness and pollution-free nature of the entire cultural relic restoration process.
Dry ice cleaning is one of the emerging applications in recent years. Although it has been used in industries such as cultural relic cleaning and ship cleaning, its market share and impact have not been significant. With the increasing public awareness of environmental protection, the increasingly stringent national environmental protection regulations, and the continuous advancement of dry ice cleaning technology, this advanced processing method has once again received attention and become a new favorite in the industrial market.
In foreign countries, the use of dry ice cleaning for cleaning stone sculptures and cultural relics is already a mature technology.
