Problems solved by technology

Ethylene oxide, methyl bromide, and sulfuryl fluoride are all efficient fumigants, but ethylene oxide is an explosive substance and has mutagenicity; methyl bromide has poor bactericidal ability, and according to the Montreal Protocol, methyl bromide It will be banned in our country; due to its hydrophobicity, sulfuryl fluoride is difficult to penetrate into water-containing eggs, so the ability to kill eggs is poor, and the deposition of fluoride has the risk of poisoning human bones

Embodiment 1

[0022] Cultural relic material: paper

[0023] Disease: Aspergillus flavus

[0024] Fumigant: citronellal (purchased from AladdinChemistry company, mass fraction is 96%)

[0025] Fumigation process: open the fumigation box with a volume of 0.4m 3 , put 1g of citronellal and paper at the same time, close the fumigation box and pass high-purity nitrogen gas, adjust the flow rate to 5L / min, adjust the temperature to 35°C, and the relative humidity to 55%, until the temperature and humidity in the box remain stable and the nitrogen purity If it is above 99.9%, close the air outlet and air inlet, and start fumigation. The fumigation time is 24 hours. After the end, the fumigation box is opened, and the paper is taken out and placed in the cultural relic preservation box.

Embodiment 2

[0036] Cultural relic material: silk

[0037] Diseases: clothes moth, small round beetle, black beetle

[0038] Fumigant: citral (purchased from Sinopharm Chemical Reagent Co., Ltd., with a mass fraction of 95%)

[0039] Fumigation process: open the fumigation box, open the fumigation box, the volume is 0.4m 3 , put 1g of citral and silk at the same time, close the fumigation box and pass high-purity nitrogen gas, adjust the flow rate to 5L / min, adjust the temperature to 35°C, and the relative humidity to 60%. After the nitrogen purity in the box is above 99.9%, Close the air outlet and air inlet and start fumigation. The fumigation time is 8 hours. After the fumigation box is finished, the silk is placed in the cultural relic preservation box. Clothes moth killing rate is 100%. Under the situation of the same treatment, the killing rate of citral to the small round beetle and the black beetle is also 100%. If only nitrogen is used for fumigation under the same temperatur...

Embodiment 3

[0051] Cultural relic material: bamboo and wood

[0052] Disease: Black beetle

[0053] Fumigant: cinnamaldehyde (purchased from Sinopharm Chemical Reagent Co., Ltd., the mass fraction is 95%)

[0054] Fumigation process: open the fumigation box, the volume is 0.4m 3 , put 1g of cinnamaldehyde and bamboo and wood at the same time, close the fumigation box and pass in high-purity nitrogen, adjust the flow rate to 5L / min, adjust the temperature to 35°C, and the relative humidity to 60%. When the nitrogen purity in the box is above 99.9% , close the air outlet and air inlet, and start fumigation. The fumigation time is 8 hours. After the fumigation box is opened, the bamboo and wood are placed in the cultural relic preservation box. The kill rate of the black beetle is 100%. If only nitrogen is used for fumigation under the same temperature and humidity conditions, the fumigation time is 1-2 weeks; only cinnamaldehyde is used for fumigation under the same temperature and humi...

Abstract

The invention discloses a novel method for disinfecting cultural relics by fumigation, which can be applied to prevention and control of pest mildew diseases of collected and exhibited cultural relics by a museum. The method is characterized in that flammable, combustible, environment-polluted and toxic fumigants such as ethylene oxide, bromomethane and the like are replaced by one or more out of safe, nontoxic and environment-friendly plant fumigants such as cinnamyl aldehyde, citronellal, geranialdehyde and the like, and composite high-purity nitrogen is used for fumigating the cultural relics, so that the efficacy of plant components can be improved; the temperature and the humidity during fumigation are adjusted, so that the cultural relics made of different materials are maintained under a relatively stable condition, and damage to the main bodies of the cultural relics is avoided.

Description

technical field [0001] The invention relates to a disinfection method, in particular to a method for fumigation and disinfection of cultural relics. Background technique [0002] Insect fungus disease is one of the main diseases of cultural relics, especially organic cultural relics. The research on the safe and pollution-free disinfection technology of the cultural relics in the collection, including the cultural relics that have suffered insect mold diseases and cultural relics before storage, is an important research direction in the scientific and technological work of the protection of historical and cultural heritage in my country. Since cultural relics are precious witnesses of material cultural heritage, and their texture is often relatively fragile, widely used physical insecticide methods such as high-temperature / low-temperature insecticide, microwave insecticide, and drying dehydration insecticide methods will have a greater impact on the physical properties of th...
