Glove case definition and classification
A glovebox is a sealed chamber device mainly used to protect water and oxygen-sensitive materials from external environmental interference, or to safeguard operators from experiments and industrial production processes. The glovebox industry has gradually developed with the increasing demands of high-end manufacturing for production environments. In scientific research institutions, university laboratories, R&D departments of innovative enterprises, and high-end manufacturing production processes, gloveboxes are essential protective equipment. Currently, the glovebox industry has developed towards a highly integrated and intelligent direction.
01
Inert atmosphere glove box
Inert atmosphere glove boxes create a water-free, oxygen-free, or dust-free sterile inert atmosphere environment to protect materials sensitive to water and oxygen from external influences. Inert atmosphere glove boxes are widely used in scientific research experiments involving the handling of materials sensitive to water and oxygen in an inert atmosphere, as well as in high-end manufacturing fields. In scientific research experiments, inert atmosphere glove boxes can protect materials sensitive to water and oxygen, ensuring the accuracy of experimental results and reducing safety risks. In high-end manufacturing, inert atmosphere glove boxes are crucial for safe production and ensuring product quality. For example, the electronics industry is highly sensitive to micron-level particles because these particles can cause short circuits between metal layers, leading to production disruptions or defective products and reducing product yield. The glove box effectively controls particles below the micron level, ensuring product quality; in lithium battery production, the middle-stage cell assembly requires the use of glove boxes to strictly control oxygen content, humidity, dust, etc., to avoid the impact of water molecules, oxygen, or dust on battery performance.
02
Protective gloves case
Protective glove boxes are used to handle toxic, radioactive, and other substances, preventing operators from coming into direct contact with harmful materials and protecting against radiation to the human body. The glove box maintains a negative pressure environment inside, which prevents harmful substances from leaking out in case of minor leaks, minimizing the risk of hazardous material spills. In addition, such glove boxes are usually equipped with high-efficiency particulate air filters (HEPA) at the exhaust port to avoid the emission of harmful substances. Protective glove boxes are widely used in fields such as nuclear material research, isotope pharmaceuticals, and hazardous chemical handling.
Among them, inert atmosphere glove boxes belong to traditional equipment, while inert atmosphere protection intelligent equipment and radiochemical grade sealed chambers are considered high-end intelligent equipment. In an inert atmosphere environment, the characteristics of high-end intelligent equipment include: 1) The power system cannot be placed inside the glove box; it requires power transmission through magnetic fluids, magnetic coupling, etc.; 2) The space inside the operating box is small, demanding that integrated equipment be compact and precise; 3) It needs to be capable of rapid disassembly and assembly. Therefore, there are essential differences between inert atmosphere protection intelligent equipment and radiochemical grade sealed chambers and traditional artificial intelligence devices.

Analysis of the Basic Structure of Standardized Gloveboxes
The construction of a standardized inert atmosphere glove box includes the glove box body, control system, gas purification system, transition chamber, detector, and vacuum pump, among other parts. The glove box body is the main space for experiments and production. The window of the box is usually made of hard transparent material to provide good visibility. At the top or side of the box, there are outlet filters, lighting, operation display screens, and an automatic control system, etc. At the bottom, inlet filters, circulating fans, gas purification systems, etc., are installed synchronously. On the front window of the glove box, there are glove ports for sealing and connecting flexible operation gloves. The gloves are fixed in the grooves of the glove ports by sealing rings, and operators enter the box through the gloves to operate. The purification column in the gas purification system is located at the bottom of the glove box. The transition chamber is located on the side of the glove box body, facilitating the transfer and movement of substances inside the box with the outside world. The detector is used to detect the atmospheric environmental parameters inside the glove box to ensure the smooth progress of experiments and production. The vacuum pump is mainly used for evacuating components of the glove box and maintaining the set pressure inside the glove box.

Based on the production needs of downstream applications, glove box manufacturers need to adjust the structural dimensions of glove boxes, add parts and equipment, and expand functions on top of standard glove boxes to adapt to different industry requirements.
01
Control system
The control system mainly consists of a control module, display screen, differential pressure sensor, hermetic valve actuator, frequency converter, lighting, alarm module, switch, power supply, etc. It can perform positive and negative pressure control, hermetic valve opening and closing, lighting control, and can record parameters such as pressure and water oxygen value inside the glove box in real time. The differential pressure of the glove box is controlled automatically by collecting the relative pressure difference between the box pressure and the external environment for air extraction and replenishment control. In case of failure of the glove box structure, rapid air extraction and replenishment operations can be carried out to effectively reduce the risk of internal and external leakage. The alarm system can give audible and visual alarms for the pressure difference of the glove box, etc.
02
Gas purification system
The gas purification system includes two adsorption materials - molecular sieves and copper catalysts. Molecular sieves absorb moisture, while copper catalysts react with oxygen to remove water and oxygen from the inert atmosphere. Due to the limited filling capacity of molecular sieves and copper catalysts, the purification system will become saturated after a certain period of time, at which point the automatic regeneration program can be initiated. By continuously changing procedures such as vacuum level, heating, and gas flow, the moisture content of the molecular sieves will decrease, and the oxidized copper catalysts will be reduced to their original state, thereby restoring the purification capacity of the gas purification system.

Analysis of the working principle of the glove box
The working principle of glove box dehumidification and deoxygenation is based on the closed-loop circulation purification process of the gas purification system. In this process, the working gas inside the glove box is circulated in a closed loop through pipes and a circulating fan, and is controlled and monitored by a PLC. When the working gas passes through the purification system, molecular sieves and copper catalysts in the system adsorb moisture and oxygen respectively. As the number of cycles increases, the water and oxygen content in the working gas inside the glove box gradually decreases, eventually reaching a target of less than 1 ppm. When the purification column is saturated with adsorption, the operator can regenerate it for reuse. The closed-loop circulation purification process ensures that the atmosphere inside the glove box remains dry and anaerobic, creating an inert atmosphere environment that meets experimental or production requirements.

Analysis of Technical Standards for Gloveboxes
The main indicators for evaluating the work results of glove boxes constructing a completely sealed inert atmosphere environment are leakage rate and water oxygen content. The leakage rate directly affects the water oxygen content in the inert atmosphere inside the box. As a basic working platform, glove boxes provide strong support for operators to complete experiments and production that have no special requirements for water or oxygen.
01
Leakage rate
The leakage rate is one of the key indicators for measuring the sealing performance of glove boxes, directly determining whether the glove box can establish the required airtight environment. The leakage rate refers to the speed at which gas leaks into/out of the glove box per unit time under specific pressure, usually described in cubic centimeters per hour (Vol/h) of leakage volume per box.
The classification of leakage rates in the glove box industry mainly refers to EJ/T 1096—1999 'Classification of Sealing Performance and Its Test Methods for Sealed Enclosures'. This standard stipulates that for sealed enclosures with a controlled inert atmosphere (Class 1 sealed enclosures), the hourly leakage rate should not exceed 5x10⁻⁴ Vol/h. Currently, the glove box industry generally adopts this Class 1 sealed enclosure testing standard, which means that the leakage rate should not exceed 5x10⁻⁴ Vol/h as an industry standard.

02
Water oxygen content
The water oxygen content is affected not only by the leakage rate but also by factors such as the purification effect of the purification system. The purification effect depends on the structure of the purification column, purification materials, gas flow rate, heating temperature of the purification column, purification procedure, etc.

Global and Chinese history of handbag cases
The development history of the global glove case industry can be summarized into three stages: exploration, growth, and development.
-
exploration phase
During World War II, due to the need for research on radioactive military materials, early glovebox products were born. The main principle of early glovebox products was to continuously fill the box with inert gas to provide an inert environment. Although it could meet the basic needs of scientific research, there were problems such as unstable water and oxygen content and high usage costs, which limited the accuracy and referenceability of experimental results to some extent. Therefore, gloveboxes did not achieve large-scale application at this stage.
-
growth period
During this phase, researchers improved the overall design of the glove box, significantly enhancing its performance. German engineers Hellmut Föllerter and Gerhard Hinrichs invented a glove box consisting of 'glove box body, transition chamber, gloves, and gas purification system,' giving rise to the initial prototype of modern glove box equipment. Additionally, Aranki et al. proposed using transparent vinyl transparent material as the glove box window, which expanded the field of view and facilitated precise experiments and production by operators.
-
development phase
With the development of science and technology, the application fields of glove boxes have further expanded, being widely used in industries such as new materials, nuclear technology, biomedicine, lithium batteries, solar cells, special welding, 3D printing, etc. Looking ahead, with further scientific and technological development, production and experimentation will place increasingly stringent requirements on the environment, and glove boxes will gradually be applied in more high-end fields.
The glove box industry in China started relatively late compared to European and American countries. In its early stages, the industry faced issues such as inconsistent technical standards, immature parts, and high costs. However, benefiting from the rapid economic growth in China and the dividends of new energy transformation, the glove box industry in China has now matured, with a rapidly growing market trend. China's glove box manufacturing technology is basically synchronized with the world's advanced level and has reached international advanced standards in the manufacture of high-performance complex large-scale glove boxes. As an important basic working platform, the glove box market in China has expanded rapidly due to the development of industries such as lithium batteries and photovoltaics. While the construction of new production lines in downstream industries has brought considerable incremental demand for glove boxes, the automation upgrade of downstream industries has also driven the procurement demand for intelligent glove box equipment.
Looking at the development history of gloveboxes, they have evolved from simple structures to complex ones; their application fields have expanded from limited use in the nuclear industry to general scientific research and high-end manufacturing; and their production process has progressed from standardization to customization to high-end intelligent equipment.

Analysis of the Current Development Status of the Global and Chinese Suitcase Industry
01 The Chinese glove box has achieved overtaking on curves, and its product performance has reached the international advanced level.
The overseas glove box industry started relatively early and has a first-mover advantage. European and American countries have an early industrialization process. The early development in fields such as chemicals, new materials, and nuclear industry has made the research, development, and production of new products and materials increasingly demanding on the production environment, leading to a rapid growth in glove box demand. European and American countries have a long history and rich experience in glove box manufacturing, and their glove box products usually demonstrate first-class levels in terms of airtightness, water and oxygen purification capabilities, performance stability, etc.
The development of the Chinese glove box industry has been rapid, with domestic leaders successfully breaking through with their high-quality products and cost-effective offerings. Since the birth of China's first fully functional purification glove box at the end of the 1990s, the Chinese glove box industry has gradually developed. After 2000, local Chinese glove box manufacturers were established one after another, including Midea, Itex, Weig Technology, etc. In the early days, Chinese glove box manufacturers gradually matured by digesting and absorbing the principles and manufacturing processes of European and American countries. With a deep understanding of the customized needs of downstream enterprises in the Chinese glove box market and mastery of glove box-related technologies, some domestic brands have now reached international industry-leading levels in terms of sealing performance, gas purification technology, and control of water oxygen content.
The market scale of China's glove box industry increased from 600 million yuan in 2018 to 960 million yuan in 2022, with a compound annual growth rate of up to 12.6% during this period. In the future, with the continuous improvement of automation in process industries, it is expected that by 2027, the market scale of China's glove box industry will reach 5.55 billion yuan, with a compound annual growth rate from 2022 to 2027 expected to be as high as 42.2%. Among them, domestic brands such as Microna achieved steady growth in market share in the international market between 2022 and 2023, increasing from 5.7% to 6%, while their share in the domestic market has significantly increased from 30% to 40%. This growth trend demonstrates the competitiveness of products and market acceptance, as well as the achievements of Chinese glove box manufacturers in global and domestic market strategies and brand building. In terms of cost, with the help of a mature industrial chain and economies of scale, the production costs of China's glove box products continue to decrease, making them highly competitive in price. The product performance and non-standard product customization capabilities are widely recognized by customers, and they have successfully entered the supply chains of leading enterprises in downstream industries such as nuclear industry and lithium battery.
02 The intelligent equipment glovebox has a wide range of applications, opening up a second growth curve for gloveboxes.
With the rapid development of industry, production demands have shifted from single machines to fully automated high-end intelligent equipment. By integrating automation equipment, information systems, and glove box intelligence, it is possible to achieve full-process atmosphere control in the production process, eliminate the impact of external environments during the production process, and greatly improve the production efficiency and product quality of industrial production lines.
Based on the scalability of the glovebox platform, glovebox manufacturers can integrate multiple technologies and functions, and achieve linkage with front-end and back-end production equipment, thereby providing complete customized and intelligent solutions. Some leading glovebox manufacturers with advanced technology and strong brand effects directly cooperate with downstream customers, offering one-stop solutions according to the customized needs of clients. This model will become one of the mainstream development directions for the glovebox industry in the future.
