Gas-filled protective display casing

Abstract

The invention relates to an aerated protective show frame which can store and show calligraphy and painting and cultural relics for ever, wherein the invention is characterized in that: putting matters into frame 1; putting frame 1 into pressure-resistant chamber 3; vacuuming the chamber 3; filling pure inert gas, to make show frame without oxygen, dust, steam, harmful air, microbe and mold; therefore, even the condition changes, the pressure will be same as atmosphere pressure, to avoid harmful physical, chemical and biological functions, to store and show matter with low cost.

Description

technical field [0001] The invention belongs to the category of security products, and relates to a device that can permanently preserve rare paintings and calligraphy and cultural relics, and at the same time can publicly display the preserved rare calligraphy and paintings and cultural relics. Background technique [0002] The precious calligraphy, paintings and cultural relics collected by museums and collectors are inevitably gradually aging and damaged due to the influence and erosion of harmful gases such as dust, water vapor, salt, oxygen, microorganisms, insect pests and sulfur dioxide in the environment. The preservation method of humidity is not only expensive, but also can only slow down, not prevent them from aging. There is also a preservation method of reducing oxygen and sealing at home and abroad. For example, the negative pressure calligraphy and painting preservation cylinder successfully developed by the Palace Museum of China in 2002 is one example. Nega...

Problems solved by technology

[0002] The precious calligraphy, paintings and cultural relics collected by museums and collectors are inevitably gradually aging and damaged due to the influence and erosion of harmful gases such as dust, water vapor, salt, oxygen, microorganisms, insect pests and sulfur dioxide in the environment. The preservation method of humidity not only costs more, but also can only slow down, not prevent them from aging

There is also a preservation method of reducing oxygen and sealing at home and abroad. For example, the negative pressure calligraphy and painting preservation cylinder successfully developed by the Palace Museum of China in 2002 is one example. Negative pressure, which can prevent pests, inhibit mold growth, slow down humidity changes, etc., so that calligraphy and painting scrolls can be preserved for a long time, but it cannot preserve oil paintings that are not resistant to folding and large cultural relics, nor can they be displayed publicly during preservation , unable to obtain due economic and social benefits
