Method for dehydrating water saturated bamboo strips

Abstract

The invention relates to a method for dehydrating water saturated bamboo strips, belonging to the technical field of dehydration protection of cultural objects. The method comprises the steps of: respectively soaking the water saturated bamboo strips for a certain time by using alcohol with different concentrations, and then re-soaking the water saturated bamboo strips by using hexadecanol and an absolute ethyl alcohol solution which have different ratios so as to ensure that water in the water saturated bamboo strips is gradually replaced and further achieve the purpose of dehydrating, wherein writings on the dehydrated bamboo strips can be clearly displayed, better stability is achieved under the condition of temperature and humidity fluctuation, anisotropic shrinkage rate is stabilized within 5 percent, the problem of getting damping caused by moisture absorption of a water-soluble filling material can not caused; and the method has the advantages of repeatable operability, can allow for unforeseen circumstances for future re-treatment of the bamboo strips, and is especially suitable for the dehydration of the water saturated bamboo strips.

Description

technical field [0001] The invention relates to a dehydration method for saturated bamboo slips, which belongs to the technical field of dehydration protection of cultural relics. Background technique [0002] Bamboo slips are pieces of bamboo or wood on which characters are written in ancient times. Among them, the bamboo slips are called bamboo slips or simply slips, and the wooden slips are called wooden slips or simply slips, collectively called slips. Judging from the information we know today, Bamboo slips are text carriers that exist all over the world. It is as close as Japan and South Korea in the ancient Han cultural circle, as far as Britain in ancient Rome, as well as Italy and Switzerland. By the beginning of this century, nearly 100,000 slips and slips had been found in Japan, thousands of wooden slips written in ink and writing from the Roman period were also discovered in Vindaland Castle in England, and dozens of water-saturated wooden slips were also disco...

AI Technical Summary

Problems solved by technology

[0004] Although the ethanol-ether continuous immersion method adopted by the British Museum can make the characters that cannot be read by the naked eye appear, but this method is not ideal for decayed and fragile wooden slips. Water Bamboo Slips are even more difficult

For the dehydration methods of saturated bamboo slips such as PEG filling, the color is darker and the writing is not clear after dehydration. Therefore, we must develop new dehydration technology to solve the dehydration protection problem of a large number of saturated bamboo slips.
