A The glove box evaporation film coating all-in-one machine is integrated with a vacuum coating system and a glove box system. Thin film evaporation is completed in a high vacuum evaporation chamber, and samples are stored, prepared, and tested after evaporation in a high-purity inert gas atmosphere in a glove box. For example, by spin coating perovskite precursor solution in a nitrogen environment of a glove box, avoiding contact with water and air, the prepared perovskite cells can be directly transferred to the evaporation electrode in the evaporation chamber through a connected storage compartment. The entire experiment can be operated in an anhydrous and oxygen free environment, effectively avoiding problems such as component color difference and hot spot effect caused by uneven coating, thereby improving the performance and durability of solar cells.

A The use of glove boxes in metal 3D printing is mainly due to safety and process requirements. From a safety perspective, important materials for metal 3D printing, such as titanium and aluminum, are reactive metals that are flammable and burn quickly, producing extremely high temperatures and pressures. The small particle size of metal powder can be inhaled into the human body, posing a health hazard to operators. The glove box can provide a fully enclosed operating space, minimizing dust exposure and hazards to the greatest extent possible. In terms of process requirements, for example, titanium alloy is a poor conductor of heat, which is prone to heat accumulation during processing. Traditional machining is difficult and has a low yield rate. However, glove boxes can provide a specific inert gas atmosphere environment to meet the environmental requirements of titanium alloy 3D printing, which helps to improve the quality and performance of printed products, such as solving the problem of oxygen embrittlement of titanium alloy in 3D printing.

A 3D printed glove boxes play a crucial role in the metal 3D printing process. It provides a safe working environment for metal 3D printing and can effectively solve many problems in the 3D printing process. For example, it can provide a pure working atmosphere environment, forming a closed loop with multi-stage dust collection devices and circulation devices. Argon gas circulates in the closed loop, making the water and oxygen content in the system reach the target of less than 1PPM, achieving an ultra-high purity working atmosphere environment and reducing the adverse effects of oxygen on metal printing processes such as titanium alloys, such as oxygen embrittlement.

A The working gas inside the glove box usually does not need to be replaced frequently under normal circumstances, which means that the glove box does not need to be cleaned frequently. If the sealing of the glove box is good, the gas circulation system and purification system can work normally, and the working gas (such as inert gas nitrogen or argon) can be circulated inside the box. The gas circulation system will continuously make the gas flow inside the box and pass through the purification system to remove oxygen, moisture, and other impurities, thereby maintaining the stability of the environment inside the box. For example, when a high-quality glove box is used for lithium battery material research, as long as its gas purification system continues to operate effectively and the working gas can be maintained within a suitable purity range for a long time to meet experimental requirements, there is no need to replace the gas inside the glove box.

A Malfunctions in the gas circulation and purification system can lead to an increase in the gas consumption of the glove box. When the circulating fan is abnormal, motor failure, impeller damage or unstable speed will reduce the gas circulation efficiency, and impurities in the box cannot be treated in a timely manner. To ensure that the environment meets the requirements, the system will supplement more working gas; Blockage or leakage in the circulation pipeline can hinder the normal circulation of gas, causing gas in some areas to be unable to renew and impurities to accumulate. Leakage can directly lead to gas loss, requiring more gas to maintain the environment; The failure of purification materials, such as molecular sieve adsorption saturation and copper catalyst failure, cannot effectively purify gases. As a result, the water and oxygen content in the glove box increases, and the system will increase the supply of working gas to maintain the ideal environment.

A The increase in gas consumption of glove boxes is related to their sealing performance, and problems with the sealing of glove box equipment can lead to an increase in gas consumption. When there are small holes, cracks, or aging wear on the gloves, external air enters, and the system will replenish more working gas to maintain the indoor environment; If the sealing gaskets around the interface between the gloves and the box, the transition chamber door, and the pipeline interface are aged, damaged, or not installed properly, gas leakage will cause a decrease in pressure inside the box, and the gas supply system will increase the gas supply; If there are leakage problems such as welding cracks or small pores in the material of the box itself, it will also cause gas loss, leading to the system replenishing more gas to maintain pressure balance.
