Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of ancient ivory reinforcement, in particular to a reinforcement method and device for unearthed ancient ivory in a humid environment. BACKGROUND
[0002] Ivory was a symbol of status and wealth in ancient times. China has a long history, and some ancient ivory and ivory ware cultural relics have been discovered and unearthed. The main features of the above-mentioned unearthed ancient ivory cultural relics in China are: first, long time span and wide distribution; second, mainly ivory ware cultural relics, but few whole ivory cultural relics; third, few ivory ware cultural relics unearthed at one time; and fourth, their functions are mainly for decoration and practical use.
[0003] In recent years, a large number of ancient ivory cultural relics have been discovered at the Sanxingdui site in Guanghan. The quantity, cultural value and particularity of these cultural relics are unprecedented in the world. However, some of the ivory is entirely charcoal gray, possibly having been burned, and covered by an ash layer containing a large amount of bamboo and charcoal debris. The ash layer absorbs a large amount of moisture, and the soil layer contains 60% water, which is 40% more than the normal water content of soil. The ivory has been immersed in a humid environment for a long time, the enamel has been reduced, and the overall texture is relatively soft. After the enamel is damaged, a large amount of water and soil from the external environment will penetrate into the ivory, even approaching a saturated state, and the ivory will begin to rot and become muddy. If the ivory is unearthed and the external environment is too dry, it will easily crack and then powder, so the protection of ivory is difficult.
[0004] Because these discovered ivory is stacked with bronze and other relics, they cannot be backfilled and stored. As for the storage method after the extraction of the ivory, one is to store it in a "low-temperature and high-humidity" environment, but it is easy to breed mold. Two is to bury the ivory in moist sand to maintain humidity and reduce cracking, but it is not conducive to exhibition. How to effectively protect these valuable and rotten ancient ivory cultural relics for a long time while allowing the public to appreciate the appearance of ancient ivory is still a big problem that needs to be solved urgently.
[0005] A patent with the patent number CN101386549A discloses a surface treatment method for paraffin-protected unearthed ancient ivory cultural relics. This method uses chloromethane and paraffin to reinforce the ivory, but chloromethane is a toxic substance that is extremely volatile and has a high safety risk. A patent with the patent number CN112852291A discloses a preparation method for organic silicone rubber for ancient ivory protection. This method uses organic silicone rubber to reinforce the ivory, but this method only keeps the ivory in the silicone rubber like amber, without deep reinforcement, and is easy to breed mold. SUMMARY
[0006] The application aims to provide a reinforcing method and device for unearthed ancient ivory in a humid environment, and solve the technical problem that the enamel of ivory is reduced due to long-term immersion in a humid environment, and the ivory is prone to cracking and pulverization due to a dry external environment, thus being difficult to protect.
[0007] The application discloses a reinforcing method for unearthed ancient ivory in a humid environment, comprising the following steps:
[0008] The plastic modification is performed first, and then the deep reinforcement is performed;
[0009] The plastic modification is performed first, and then the deep reinforcement is performed;
