Abstract

The invention relates to a method for charging shielding gas into a cultural relic experiment chamber. The method comprises the step that the shielding gas with the determined concentration in a gas source device is charged into the cultural relic experiment chamber to completely replace air in the cultural relic experiment chamber, so that the concentration of the shielding gas in the cultural relic experiment chamber reaches the needed concentration. According to the method, the final concentration of the shielding gas in the cultural relic experiment chamber is equal to the concentration of the shielding gas coming from the gas source device, and therefore the concentration of the shielding gas in the cultural relic experiment chamber is easily guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of cultural relics protection, and in particular relates to a method for filling protective gas into a cultural relics experimental cabin. Background technique

[0002] At present, at the archaeological excavation site, that is, when the cultural relics have just been unearthed, effective preventive protection measures or equipment are not adopted, and the cultural relics at the excavation site cannot be protected and processed in time, which will cause the unearthed cultural relics to be damaged by oxygen, humidity, polluting gases, and harmful organisms. And mold and other factors cause oxidation, deterioration and other damage.

[0003] The Chinese patent with the authorized announcement number CN201536872U discloses an active nitrogen-enriched cultural relics protection system, including a protection space for placing cultural relics (equivalent to a cultural relics experiment cabin), a nitrogen generato...
