Low-temperature rapid partial freezing preservation technology for cultural relics

Abstract

The invention provides a low-temperature rapid partial freezing preservation technology for cultural relics. According to the technology, an ice crystallization state of biological cells in a low-temperature state is researched by adopting a high-technology biotechnology, the low-temperature and ultralow-temperature technology, and innovative partial freezing liquid with natural components are applied, and the cultural relics to be frozen-stored are directly frozen and stored in the partial freezing liquid by using an innovative freezing curve. According to the variety and the size of objects,freezing preservation of the cultural relics is completed within 6-15 minutes, or 15-30 minutes. The technology has the advantages that the cell membranes in the frozen-stored cultural relics are notfrozen-cracked, and are in an organism partial freezing state, and then the frozen-stored cultural relics are kept in a cold storage mode, so that the quality of the cultural relics is fresh and alive; the low-temperature rapid partial freezing technology is an innovative partial freezing storage technology in the world, the cultural relic cells are kept from being broken, and conversion of the cultural relic polysaccharide substances is increased. The fresh cultural relics can still keep fresh and alive even after being stored for more than 10 years under the cold storage condition on the basis of the freezing curves of the fresh cultural relics in the shortest time.

Description

1. Technical field [0001] The invention relates to the technical field of low-temperature preservation of cultural relics, and proposes a low-temperature rapid micro-freezing preservation technology for cultural relics. 2. Background technology [0002] We have found that in nature, the somatic cells of hibernating animals have a natural antifreeze mechanism, such as frogs, loach, crucian carp, and other animals and aquatic animals that live in subtropical and frigid regions. The polysaccharide antifreeze substances of somatic cells have a sharp increase in the number of double bonds of fatty acid molecules in their subcellular membranes. The antifreeze is studied from the perspective of cell dynamics, so that the somatic cells are not frozen due to the drop in external temperature. Crystal frost heaves and ruptures; organisms preserve their living bodies by keeping their body cells in a slightly frozen state, and recover and revive when the temperature rises. The evolution...

AI Technical Summary

Problems solved by technology

In the industrialized production process of cultural relics freezing and cold storage, when the temperature of the freezing equipment drops, ice crystals are first formed between the cells of the cultural relics, and as the temperature gradually decreases, ice crystals are formed in the cells again, which leads to an increase in the pressure inside and outside the cells balance, thereby destroying the protoplasm and cell membrane, resulting in cell lysis and death
