Kangbeijing's Plasma Technology Applied in Gansu Provincial Museum for cultural relics Protection

The Gansu Provincial Museum, a core institution for cultural heritage protection and display in Northwest China, has recently made innovative progress in preventive cultural relics protection by introducing Kangbeijing's plasma air purification and disinfection technology. This move aims to address the microbial threats in the cultural relics storage and display environment through scientific and technological means, providing a non - corrosive and sustainable protective barrier for fragile cultural relics.

Gansu is located on the ancient Silk Road and houses a large number of organic - material cultural relics such as painted pottery, bamboo slips, and silk fabrics. These relics are extremely sensitive to temperature and humidity changes and are vulnerable to mold erosion. For instance, bamboo and wood slips can be completely damaged by mold within 10 days in an environment with humidity exceeding 60%. Although the Gansu Provincial Museum has controlled the environmental parameters within 18 - 22°C and humidity 40 - 60% through a constant temperature and humidity system, extreme weather may still cause fluctuations, accelerating microbial growth. Moreover, traditional chemical fumigation methods, although capable of killing molds, have risks such as corroding the surface pigments of cultural relics and leaving chemical residues, which go against the principle of "minimum intervention" in cultural relics protection.

Kangbeijing's plasma air purification and disinfection technology, based on the Dielectric Barrier Discharge (DBD) principle, ionizes air to release high - density positive and negative ion clusters, which actively attack the cell membranes and genetic materials of microorganisms, achieving broad - spectrum disinfection. Its technical characteristics highly match the needs of the Gansu Provincial Museum:

1.Non - corrosive and Material - compatible: During the plasma disinfection process, no ozone (concentration below 0.1mg/m³) or chemical residues are produced, avoiding oxidative damage to sensitive materials such as the glaze of painted pottery and the fibers of calligraphy and paintings.

2.Dynamic Environment Adaptability: The equipment can monitor environmental parameters in real - time and adjust the ion release intensity according to temperature and humidity changes, maintaining continuous purification in enclosed spaces such as exhibition cabinets and storage rooms. For example, for painted pottery cultural relics, the technology can precisely inhibit the activity of mold spores while avoiding physical damage caused by condensation in traditional freezing methods.

3.Human - machine Co - existence and Intelligent Management: The equipment can operate without isolating cultural relics or clearing the site, and supports remote monitoring and data tracing, seamlessly connecting with the museum's intelligent management system.

The Gansu Provincial Museum has applied Kangbeijing's technology in three major scenarios, comprehensively improving the micro - environment control level of cultural relics:

1.Cultural relics Storage: For high - risk cultural relics such as ancient books and silk fabrics, the continuous ion release from the plasma module reduces the concentration of mold spores in the air of the storage room by more than 90%. Combined with optical fiber spectroscopy detection technology, early warning of microbial activity can be achieved.

2.Exhibition Cabinets and Halls: In popular exhibitions such as the "Special Exhibition of Wei and Jin Dynasty Portrait Bricks in Gansu," the equipment is embedded in the ventilation system of exhibition cabinets, forming a local purification barrier. Data shows that within three months after the exhibition opened, the microbial contamination rate on the surface of exhibits decreased by 76%, and there was no feedback of discomfort from visitors due to disinfectant odors.

3.Restoration Studios: During the cultural relics restoration process, dust and microorganisms generated are likely to cause secondary pollution. Kangbeijing's technology provides a clean working environment for restorers through circular disinfection, while avoiding the interference of chemical disinfectants on restoration materials (such as ancient - style paste).

The practice of the Gansu Provincial Museum provides triple demonstration value for the cultural relics industry:

1.Technology Integration and Innovation: The combination of plasma disinfection with Internet of Things and environmental monitoring technologies promotes the shift of cultural relics protection from "passive restoration" to "active prevention."

2.Cost - effectiveness Optimization: Kangbeijing's equipment does not require frequent consumable replacement and has a power consumption of less than 50 watts, significantly reducing the operation pressure of grass - roots museums.

3.Standardized Promotion Potential: The Gansu Provincial Museum, in collaboration with Kangbeijing, has formulated the "Technical Specification for Plasma Disinfection in Museums," providing a reusable technical standard for the industry and facilitating the technological upgrading of similar institutions such as the Dunhuang Academy and Tianshui Maijishan Grottoes.

In the future, the Gansu Provincial Museum plans to expand the plasma technology to more complex application scenarios:

1.Emergency Protection at Archaeological Sites: For the temporary storage environment of unearthed cultural relics, develop portable disinfection equipment to inhibit the proliferation of microorganisms during the transfer of cultural relics.

2.Cross - sectoral Collaborative Innovation: Cooperate with medical institutions to further improve the biosafety level of the cultural relics display environment by drawing on the air purification standards of operating rooms.

3.Public Science Popularization Empowerment: Through transparent display cabinet visualization technology, show the plasma disinfection process to the public and spread the concept of scientific cultural relics protection.

The introduction of Kangbeijing's plasma technology by the Gansu Provincial Museum is not only a revolution in traditional anti - mildew methods but also a vivid practice of the concept of "co - existence of technology and humanity" in the field of cultural relics protection. Through precise and harmless environmental control, the museum has built an "invisible shield" for thousands - year - old cultural relics and explored a modern protection path that balances safety, economy, and sustainability for the industry. In the future, with the integration of more innovative technologies, the goal of prolonging the lifespan of cultural relics will be achieved more quickly, and the contemporary value of cultural heritage will be activated at a deeper level.
