A The repair methods for glove box leakage mainly include glove repair or replacement, transition chamber sealing repair, and box leakage repair. For damaged gloves, minor repairs or replacement with new gloves can be carried out. The repair of the transition compartment seal requires the replacement of damaged sealing strips or adjustment of the cabin door position to ensure good sealing. Box leakage repair includes interface sealing repair and box crack repair, with specific methods including replacing damaged sealing gaskets and repairing cracks with sealant. After the repair is completed, it is necessary to conduct another leak check to ensure successful repair.

A The methods to determine the location of the glove box leakage mainly include visual inspection and pressure testing as auxiliary inspections. The appearance inspection requires a careful examination of the overall condition of the gloves, transition compartment, and glove box, including whether the gloves are damaged, whether the sealing strip of the transition compartment door is intact, and whether there are cracks or loose parts in the glove box. The auxiliary inspection of pressure testing is divided into positive pressure testing and negative pressure testing. By using a vacuum pump to adjust the pressure inside the glove box and observing the pressure changes, the leakage location can be determined.

A When replacing the sealing gasket of the glove box, it is necessary to ensure that the sealing ring is installed in place and not twisted or folded. If glue is used to fix it, it should be applied according to the instructions and wait for it to dry and solidify. During the process, ensure that the gloves and interface positions are correct; After the replacement of the sealing ring, a leakage test is required to avoid leakage caused by incorrect installation of the sealing ring.

A When replacing the sealing gasket of the glove box, the appropriate sealing gasket should be selected according to the model of the glove box and the usage environment. Glove box sealing gaskets are usually made of materials such as rubber or silicone, which have good elasticity and sealing properties. If the glove box comes into contact with chemicals or is in a special environment such as high temperature, it is necessary to choose gasket materials that can adapt to the corresponding conditions, and ensure that the specifications of the gaskets match the glove box.

A As a precision laboratory equipment, the glove box has very specific requirements for power supply to ensure its stable and safe operation. Normally, the power supply voltage required for glove boxes is 220 volts AC, which is the standard voltage for most industrial and laboratory environments. In addition, the frequency of the power supply is also very important. For glove boxes, the recommended frequency is generally 50 hertz, which matches the grid frequency of many countries. Maintaining the correct voltage and frequency is crucial for the stable operation of the electronic control system, sensors, and possible additional equipment (such as purification systems) inside the glove box. If the voltage or frequency is unstable, it may cause a decrease in equipment performance and even damage internal components.

A Different models of glove boxes may have different functions and configurations. The standard glove box needs to have the basic function of providing a water and oxygen free environment. The lithium battery glove box experimental machine integrates various functional components such as renewable organic solvent adsorbers, HF adsorbers, cooling equipment, and ovens, specifically designed for lithium battery and supercapacitor research. The glove box in the OLED field is equipped with high-precision filtering systems and gas control systems, as well as experimental equipment and tools specifically designed for OLED preparation and testing. In addition, there are welding series glove boxes, 3D printing glove boxes, and glove box evaporation machines, each with specific functions and configurations to meet the needs of different fields and experiments.

A There are significant differences in size and workstation between glove boxes of different models. Small portable glove boxes are small in size and have limited internal space. They are usually single station and suitable for simple small-scale experiments. The medium-sized standard glove box has a moderate size and a large internal space, mostly with single or double workstations, suitable for most routine laboratory operations and small-scale production activities. Large multifunctional glove boxes have larger dimensions and spacious interior spaces, often serving as multi station glove boxes, suitable for large-scale scientific research projects and industrial production. In addition, there are multi station glove boxes, such as double-sided dual station, single-sided dual station, etc., which allow multiple people to operate simultaneously or perform parallel processing of different steps for collaborative action.

A To extend the service life of the glove box, attention should be paid to the correct operation method of the glove box and the timeliness and quality of its maintenance. Strictly follow the recommendations of the glove box supplier to use the glove box correctly. For example, during operation, operators should avoid excessive stretching of gloves, contact with sharp tools, and rough movements, otherwise it may cause glove damage and affect the sealing of the glove box. Regular maintenance operations should be carried out, such as timely replacement of aging sealing gaskets and purification materials. If the purification materials are not replaced for a long time, the adsorbent will become saturated and unable to effectively remove impurities, which will lead to a decrease in performance; Regularly inspect and clean the interior of the box, pipelines, valves, vacuum pumps, and other components to remove dust, impurities, and chemical residues, and prevent component blockage and corrosion; Regularly calibrating sensors and controllers can ensure the accuracy of environmental control.
