A The low pressure inside the glove box may be caused by gas leakage, automatic air supply system malfunction, or gas circulation system malfunction. Soap bubble detection method can be used to apply soap solution to areas prone to leakage such as gloves, operating ports, box doors, pipeline interfaces, etc., to check for gas leaks and promptly repair the leak points. Secondly, if no leakage is found or the pressure is still too low after repair, it is necessary to add inert gas such as nitrogen or argon to the glove box. During this process, check whether the automatic gas supply system is working properly. If the above measures are ineffective, the gas circulation system should be checked, including whether the circulation fan is operating normally and whether the gas pipeline is blocked, and corresponding maintenance and cleaning measures should be taken.

A When the pressure inside the glove box is too high, emergency exhaust operation should be carried out immediately. Firstly, try opening the exhaust valve to quickly release excess gas and reduce the pressure inside the box. If the glove box is equipped with a foot pedal exhaust or manual exhaust device, it should be started immediately. If the exhaust valve cannot work properly or the exhaust speed is too slow, it is possible to consider opening a backup exhaust channel, such as an emergency exhaust hole. At the same time, after the pressure returns to normal, it is necessary to check whether the intake valve is not tightly closed or out of control, and whether the pressure sensor is malfunctioning, which may be the reasons for the high pressure. After taking these measures, attention should be paid to the subsequent inspection and repair of the system, as the glove box has automatic exhaust and inflation detection. If there is an abnormal increase, it must be a problem that needs to be investigated.

A Glove boxes generally use molecular sieves to remove moisture. The regular microporous structure of molecular sieves matches the pore size of water molecules and can selectively adsorb water. Water molecules are adsorbed on the surface of molecular sieves through physical adsorption. The circulating fan drives gas flow, and when the gas inside the glove box passes through the molecular sieve purification column, water molecules are adsorbed, thereby reducing the humidity of the gas inside the box. After treatment with a molecular sieve purification column, the humidity of the gas inside the glove box will gradually decrease, and the specific effect depends on the performance and usage time of the molecular sieve.

A By utilizing the good sealing and controllable inert atmosphere of the glove box, multiple scientific studies can be conducted on lunar soil powder samples. Using glove box gloves to observe and classify mineralogy without direct hand contact with lunar soil, a high-power optical microscope is used. At the same time, inert gas mass spectrometer, electron probe, and high-precision laser ablation inductively coupled plasma mass spectrometer are used to determine the content of inert gases such as helium-3 in lunar soil, analyze the chemical composition of minerals in lunar soil samples, and conduct micro area analysis of lunar soil samples to determine the content of major and trace elements. The use of glove boxes ensures the stability and purity of the research process, providing accurate research data for researchers.

A The composition and structure of lunar soil are of great research value, as the air and moisture on Earth can easily contaminate lunar soil and alter its characteristics. The glove box can be filled with inert gases such as nitrogen, maintaining a pure environment without water or oxygen inside, isolating air and moisture, avoiding oxidation, moisture, and other pollutants affecting the lunar soil sample, ensuring its original state and purity, laying a reliable foundation for subsequent accurate analysis, and enabling research to be based on uncontaminated lunar soil samples, ensuring the scientific and accurate nature of the research.
