Description

Technical Field

[0001] The utility model relates to the technical field of wooden cultural relics processing equipment, in particular to a dehydration device for dehydrating wooden cultural relics based on a glyoxal method. Background Art

[0002] Wood lacquerware has a long history in China. According to relevant ancient documents, it can be traced back to before the Shang and Zhou dynasties. However, according to recent archaeological excavations, such as the lacquered parts unearthed from Jingtou Mountain, it is proved that my country used lacquerware much earlier than the written records, and it has a history of at least 8,300 years. Due to the long-term corrosion of water, salts and microorganisms in the buried environment, the polysaccharide components (cellulose and hemicellulose) in the unearthed wood lacquerware have been seriously degraded, and the cell walls of the wood are also seriously damaged. Especially in areas with abundant groundwater, the moisture content of unearthed wood lacquerware can reach up to 1900%. If these water-saturated wood lacquerware are not scientifically dehydrated and reinforced before drying, they will be seriously deformed, cracked or even damaged.

[0003] The glyoxal dehydration method is to treat the lacquered wood with monomers, so that the monomers can completely penetrate into the wood, and then initiate a polymerization reaction under certain conditions to form a macromolecular polymer to support the wooden body. Glyoxal is the simplest dialdehyde. In aqueous solution, glyoxal exists in the form of hydrates. Its chemical properties are very active, and even under the influence of a little dust, it can cause its polymerization. The main component of wooden lacquerware is cellulose, and the molecular chain of cellulose contains many hydroxyl groups (-OH). The polyglyoxal hydrate in the reinforcement liquid also contains a large number of hydroxyl groups. Therefore, through the action of hydrogen bonds, the reinforcement liquid can easily penetrate into the interior of the wooden lacquerware and replace the water molecules therein. During drying, the hydroxyl groups on the glyoxal hydrates associate with the hydroxyl molecules on the wood cellulose to form a network structure, thereby strengthening and fixing the wooden body. In addition, glyoxal polymers can be dissolved in water under given conditions and are reversible. The glyoxal dehydration method is suitable for lacquered woodware of various shapes and ages, and has a high success rate. In addition, it can automatically adjust to a balanced state to adapt to the relative humidity conditions of the storage environment, so it has strong adaptability to climatic conditions.

[0004] Traditional methods for dehydrating, shaping and reinforcing water-saturated wooden lacquerware include natural drying method, alum method, sucrose method, resin method, PEG method, etc., but they have the disadvantages of narrow application range, acid absorption and deliquescence, easy mildew, poor permeability and low strength. Therefore, in view of the above shortcomings, a dehydration device based on the glyoxal method for dehydrating wooden cultural relics is proposed. Utility Model Content

[0029] Working principle: first put the dehydration bucket into the adjacent side of the two clamping blocks 12, then the clamping block 12 will be stressed when it is put in, then the connecting rod 11 will be driven to move under the force of the clamping block 12, then the moving block 10 will be driven to move outside the fixed column 8 under the movement of the connecting rod 11, then the strong spring 9 will be driven to contract under the movement of the moving block 10, and the strong spring 9 will generate a rebound force under contraction to provide a force to clamp the dehydration bucket and ensure the stability of the dehydration bucket, then put the wooden cultural relics in, and then put in the glyoxal solution, The wooden cultural relics are soaked, and then the sealing cover 3 is closed, so that the sealing ring 4 and the top inner wall of the barrel body 2 are closed to ensure the sealing of the barrel body 2, and then the containing plate 5 is pushed into the bottom end of the barrel body 2 to make the heating plate 6 work, and the hot air is dissipated into the interior of the barrel body 2 through the through hole 14 to heat the wooden cultural relics inside, and then the temperature detection meter 20 is used to ensure that the solution temperature is stable within the appropriate dehydration temperature range, and then the leakage detection meter 15 and the vacuum pump 31 are used to ensure the sealing of the barrel body 2 and the maintenance of the vacuum environment to promote the dehydration process.
