As the production technology of electronic products becomes more and more intelligent, the integration of various materials and devices becomes higher and higher, which leads to the need for better moisture-proof measures. Therefore, the use of moisture-proof cabinets has long become one of the standard equipment in various factories. In order to meet the storage needs of various products, the function and performance of the moisture-proof cabinet are also strengthened. At present, physical dehumidification and moisture-proof cabinets and nitrogen cabinets are commonly used in industry. So, what are the differences between them?
Physical dehumidification and moisture-proof cabinets mainly use physical adsorption molecular sieves to drain water out of the cabinet through a specific method, and this cycle makes the humidity in the cabinet reach a low-humidity environment. The physical dehumidification and moisture-proof cabinet is characterized by easy use, direct plug-in and use, intelligent adjustable humidity, good dehumidification effect, low power consumption, no noise, no thermal effect, and no magnetic hazard. It is suitable for most occasions.
Nitrogen-filled moisture-proof cabinet, also known as nitrogen cabinet, mainly uses intelligent nitrogen-filling device to fill with nitrogen, which can achieve moisture-proof and low-humidity and anti-oxidation effect. The use of nitrogen cabinets is mainly for the anti-oxidation storage of various oxidation-sensitive materials and devices.
The difference between the two is actually mainly in performance and functionality. In terms of performance, the physical dehumidification and moisture-proof cabinet can be set to medium humidity, low humidity and ultra-low humidity according to storage requirements, and the low humidity capacity can also reach a relatively good state. But in terms of dehumidification speed, it is far from being compared with a nitrogen tank. The nitrogen cabinet is used with nitrogen and has the ability to quickly dehumidify. It can quickly drop the humidity to below 5% RH. It only takes about 5-10 minutes to open and close the door. It is suitable for frequent door opening and closing occasions. Functionally, the physical moisture absorption function can still be used to continue dehumidification after the power is cut off, and the humidity will not rise more than 10% within 24 hours. The nitrogen cabinet mainly uses the humidity setting value to control the air intake, which can improve the cleanliness of the cabinet and has the effect of anti-oxidation.
It can be seen from the above that physical dehumidification and nitrogen-filled dehumidification have their own advantages and disadvantages. Different types of moisture-proof cabinets can play their different roles. As long as the storage effect can be selected, it is appropriate.
