Moisture-proof cabinets, as the name suggests, are cabinets that are designed to prevent moisture. What is the difference between a nitrogen cabinet and a moisture-proof cabinet?
Nitrogen cabinet is a traditional anti-oxidation storage device, which can be configured with different control functions according to application requirements, and is used in microelectronics, semiconductor and other industries. Do you know the difference between a nitrogen dry box and a moisture-proof cabinet? Nitrogen cabinets are traditionally used as anti-oxidation storage devices, and moisture-proof cabinets are anti-oxidation storage devices that have emerged in recent years. So what are the benefits of anti-oxidation storage in electronic moisture-proof cabinets today? What is the difference between anti-oxidation storage in nitrogen cabinets? In the past, moisture-proof cabinets were mainly used for moisture-proof storage, and anti-oxidation storage was rarely used. For the oxidation of items, the oxidation reaction mainly occurs when oxygen in the air contacts metal materials. The anti-oxidation method of the nitrogen cabinet is to create an oxygen-free environment in the cabinet to achieve the anti-oxidation effect. In fact, in addition to the reaction of oxygen, the catalytic effect of moisture is also obvious, so electronic moisture-proof cabinets will be used to create a low-humidity environment for storing metal materials to prevent oxidation.
In terms of effect, the oxygen-free environment created by the nitrogen cabinet is definitely a better way to prevent oxidation, while the anti-oxidation of the moisture-proof cabinet only reduces the oxidation reaction to a relatively low level, so it has no effect on the product. At first glance, the effect of the nitrogen cabinet is undoubtedly better, but in fact the operation of the equipment cannot reach the ideal state. Even if the nitrogen concentration in the nitrogen cabinet can reach 90%, it is ideal, but the 90% nitrogen concentration will also produce oxidation reactions. Similarly, the anti-oxidation storage of electronic moisture-proof cabinets also requires relatively good performance of the equipment. In order to achieve good anti-oxidation effects, the moisture-proof cabinets need to have fast and ultra-low humidity functions. If it is below 5%RH and has the performance of quick recovery of humidity in 5-10 minutes, it can achieve the same anti-oxidation effect as the high-purity large-flow nitrogen cabinet.
Such as dry cabinet for electronic components, optical instruments, tea, etc. Now there are many brands of moisture-proof cabinets on the market. It can be said that its appearance has greatly improved people's home life. In the future, there is no need to worry about things being damp due to long storage time. Because its technology has been improving, there are more and more types of moisture-proof cabinets. At present, there are mainly electronic moisture-proof cabinets and nitrogen moisture-proof cabinets. According to their moisture-proof items, they can be divided into three types: ordinary electronic moisture-proof cabinets, low-temperature baking moisture-proof cabinets, and professional camera moisture-proof cabinets. Different types of moisture-proof effects are different. At present, there are many brands of moisture-proof cabinets on the market. These brands have different products and have been recognized by consumers in different fields.
Nitrogen cabinets create a low-oxygen, low-humidity inert gas environment by injecting high-purity nitrogen, effectively preventing chemical reactions in precision electronic components, semiconductor devices and other items that are sensitive to oxidation and moisture. The core is that nitrogen replaces air, reducing the oxygen concentration to below 1%, and with a sealed design to ensure long-term storage stability. In contrast, moisture proof cabinets use high-efficiency dehumidification technology (such as molecular sieves or condensation dehumidification) to accurately control the relative humidity in the cabinet within the range of 1%-60%RH, which is suitable for storing items that are sensitive to humidity but not high in oxygen requirements, such as optical instruments or chemical reagents. Both have different focuses in the technical path: nitrogen cabinets emphasize all-round protection, while moisture proof cabinets focus on humidity management. Companies can choose the appropriate solution based on the characteristics of the material.
The selection of nitrogen cabinets or moisture proof cabinets requires a comprehensive consideration of the sensitivity of the stored items, production environment requirements and budget. Nitrogen cabinets are suitable for storing high-value materials that are sensitive to both oxidation and humidity, such as IC chips and precision alloys. They need to be equipped with a nitrogen supply system and consider operating costs; moisture proof cabinets are more suitable for scenarios with limited budgets or only humidity control, such as PCB boards and laboratory samples. They are easy to install and have low maintenance costs. It is recommended that B-end customers evaluate:
1) the storage cycle and environmental standards of the items;
2) the matching of equipment capacity and factory space;
3) whether it is necessary to comply with ISO or ESD standards. Kunshan Gaoqiang provides customized consulting to help companies optimize storage solutions and ensure production efficiency and material safety.
