Senluo Co., Ltd. uses normal pressure and low oxygen to regulate insecticides to accurately solve the pain points of collections.

In recent years, the country and the government have attached great importance to the work of antiquities, from attaching great importance to the protection of antiquities to paying full attention to the protection, inheritance, and utilization of antiquities. The 2024 government work report proposed for the first time “strengthening the systematic protection and rational use of antiquities.”

As precious antiquities that bear witness to human history, from archaeological excavation, cleaning, analysis and research, to preservation and storage, they are all affected by temperature, humidity, light, air pollutants, etc. in the external environment. Among them, the problem of insect mold is a serious threat to antiquities. One of the factors of longevity.

Traditional pest control services are difficult to meet the needs of collections

For a long time, collection staff have tried a variety of methods to protect ancient books and museum collections and control pests and mold, such as chemical fumigation, freezing, radiation, vacuum nitrogen filling, etc.

Although chemical fumigation is highly effective in killing insects, chemicals are often highly toxic and can cause environmental pollution and endanger human health. Volatilizing agents can remain, which may cause corrosion and damage to antiques or books. Long-term use of chemicals Pesticides will cause pests to become resistant to pesticides, thus affecting the effectiveness of pesticides.

Although freezing insecticide can kill pests in various forms and is environmentally friendly and pollution-free, this method is cumbersome to operate and is not suitable for all material collections. For collections of paintings, calligraphy and paintings, once the temperature recovery speed is not controlled well during the freezing process, it is very easy to damage the antiquities due to surface condensation.

For radiation insecticide, ultraviolet radiation can quickly destroy the cells of organisms and has a killing effect on various organisms. However, at the same time, higher intensity radiation will reduce the mechanical strength of paper collections and cause the pigments of writing to fade. Affects the durability of books and archives. The biggest problem with vacuum nitrogen filling for insecticide is that the vacuum operation will cause damage to ancient artifacts and fragile files in the cavity.

Only by fully considering the material characteristics, preservation conditions and batch requirements of the collection can we protect the collection more scientifically and maintain its integrity and value during long-term preservation. Whether it is chemical fumigation, freezing, radiation, or vacuum nitrogen filling for insecticide, it can play a certain role in the protection of library and museum collections and the prevention and control of pests and mold. But at the same time, these methods also have their own shortcomings, either polluting the environment or damaging the antiquities. At this time, we can’t help but ask: Is there a better method that can not harm the antiquities and avoid environmental pollution, such as If there is demand, can the disinfection be completed in large quantities?

Normal pressure and low oxygen regulation for insecticide, a new plan for insect and mold control

This has to mention the atmospheric pressure and low oxygen regulation insecticidal equipment and services of Tianjin Senluo Technology Co., Ltd. (hereinafter referred to as: Senluo Technology Co., Ltd.). As a forward-looking innovation in insecticide technology, Senluo Co., Ltd.’s normal-pressure and low-oxygen regulated insecticide relies on a new generation of intelligent gas control technology in highly enclosed environments (referred to as “CATHSE” technology). It is based on an airtight enclosure structure and uses Clean nitrogen is used as an insecticidal gas to replace the original air in the airtight space, reducing the oxygen concentration to 0.5% and below, isolating the oxygen source that insects and mold sources rely on to survive, and achieving the purpose of pest and mold control. At the same time, with the assistance of temperature and humidity control technology, gas cleaning technology, intelligent monitoring and information technology, we create a constant humidity, low oxygen, and clean microenvironment to achieve the ultimate goal of harmless insecticide.

In fact, low-oxygen technology has been used for a long time in the prevention and control of insects and mold in books and ancient books. In the 1990s, the Getty Research Institute in the United States demonstrated the impact of low-oxygen environments on the survival conditions of common pests in museums. Since 2013, Senluo has jointly carried out a number of experimental studies on low-oxygen regulation technology with the Institute of Archives Science and Technology of the State Archives Administration, the National Library, and Renmin University of China in terms of slowing down the aging and deterioration of paper, killing insects and inhibiting bacteria, etc. , time and time again, it has been proven with clear data that the normal pressure and low oxygen controlled insecticide method has wide application value. Among them, “Research on the Application of Low Oxygen Conditioning Technology in the Prevention, Control and Storage Protection of Paper Archival Insects and Mold” won the “Second Prize for Outstanding Scientific and Technological Achievements of the State Archives Administration in 2018”.

At present, Senluo’s normal pressure and low oxygen regulated insecticidal equipment and services have been successfully used in the Palace Museum, the National Museum of China, the National Museum of China (Beijing, Xi’an, Hangzhou, Guangzhou), China National Silk Museum, Shanghai Library, Chongqing Hundreds of key cultural and museum institutions, including the Hongyan Museum of Revolutionary History and the Tianjin Museum, use effective methods to protect books, ancient books, and precious collections from pests and mildew. Based on the excellent performance of normal pressure low-oxygen controlled insecticide in practical applications, Wuhu Municipal Museum and Bengbu Municipal Museum both selected Senluo Co., Ltd. as a technical support partner based on their own needs and determined a flexible low-oxygen insecticide service plan.

Atmospheric pressure and hypoxia insecticide service, precise protection of museum antiquities

As a local comprehensive museum, the Wuhu Municipal Museum is responsible for the collection of antiquities, cultural inheritance, scientific dissemination, comprehensive services and other functions. In order to better effectively protect the collection, the museum will move a batch of furniture, paintings and calligraphy into a new warehouse. In view of the large volume Due to requirements such as disinfection, antiques of varying sizes, and placement based on on-site conditions, the Wuhu Museum conducted research on insecticide technology and finally chose the mature atmospheric pressure and low oxygen regulation technology of Senluo Co., Ltd.

Senluo Co., Ltd. combines various factors such as convenience, safety and insecticide service efficiency, and uses the method of setting up flexible air-tight tents on site to carry out disinfection. The air-tight tent can be sealed and disinfected on-site according to the location of the ancient objects; furniture, paintings and calligraphy can be placed in the same air-tight tent, without the need to classify and disinfect according to the material, and has better universality; during the insecticide period , the oxygen content in the airtight space is always maintained below 0.5%. After the insecticide is completed, all the indicated insects in the tent have been killed, and the pest mortality rate reaches 100%.

At the same time, when sterilizing furniture, calligraphy and paintings, Senluo Co., Ltd. also integrated digital intelligence solutions, using a remote intelligent multi-point monitoring system to realize real-time online monitoring, display, storage, and query of oxygen, temperature and humidity in each tent. With safe, environmentally friendly and convenient normal pressure and low oxygen adjusted insecticide services, it provides precise protection for the collections in the museum.

In order to better achieve preventive protection of antiquities, the Bengbu Municipal Museum needs to carry out pest control treatment on more than 700 precious calligraphy, paintings and books. Due to the fragility of calligraphy, painting and books, radiation or freezing insecticide may cause adverse effects such as fading of writing and loss of strength, while chemical fumigation and insecticide may threaten the environment and human body. Therefore, it is more harmless, environmentally friendly, and Smarter normal-pressure and low-oxygen controlled insecticide technology has become a priority for the Bengbu Museum.

Senluo Co., Ltd. built a flexible air-tight tent with an air exchange rate of 0.02d-1 and a volume of 30m³ for the Bengbu Museum, and completed the batch sterilization of calligraphy, paintings, and books. During the disinfecting process, the airtight space is always under normal pressure, which avoids damage to fragile paper antiquities caused by pressure changes; continuous monitoring data shows that during the killing period, the oxygen content in the tent is stably maintained below 0.5%, reaching 100 % disinfect. Relying on its advantages in technology and experience, Senluo successfully completed the disinfection task and successfully passed the acceptance of the Bengbu Municipal Museum.

The successful application of Senluo Co., Ltd.’s normal pressure and low-oxygen adjusted insecticide service in Wuhu Museum and Bengbu Museum has achieved effective protection of the collections in the museum, which not only confirms the effectiveness of low-oxygen technology in the field of antiquities protection with zero pollution, zero residue, and zero damage. It has practical effects and at the same time demonstrates the advantages of large-scale insecticide services, no space restrictions, and the ability to be deployed at any time when there is a need for disinfection. It is another breakthrough technological advancement in the field of preventive protection of cultural heritage.

In the future, Senluo Co., Ltd. will continue to increase investment in innovation, deeply solve the pain points of collection protection, create a more complete product system, and implement core technologies to promote industrial change and contribute to the development of Chinese culture based on the high standards and strict requirements of the birthplace of preventive protection technology.
