In the market, the price of civilian moisture-proof cabinets is much cheaper than that of industrial moisture-proof cabinets. Some customers have questions. Since civilian-use moisture-proof cabinets can also achieve the purpose of moisture-proof, why do we have to choose industrial moisture-proof cabinets? Is the civilian moisture-proof box really suitable for industrial storage materials? Let's analyze together with questions.
1. Civil moisture-proof boxes, most of their dehumidification systems use simplified semiconductor condensation chip dehumidification technology. The main goal is to prevent the storage of items that are sensitive to moisture such as cameras, lenses, antiques, and documents, and prevent items from being caused by moisture. Abnormalities such as mildew and deterioration. The dehumidification capacity of semiconductor condenser chips is very limited, and the relative humidity requirement is generally below 50%RH. Therefore, the civilian moisture-proof box is only suitable for storage requirements in small areas or low humidity requirements. The industrial moisture-proof box generally requires the storage of the corresponding humidity of the MSD according to the different humidity sensitivity levels specified by the IPC. In the new version of the IPC standard, it is stipulated that MSD of level 3 and below needs to be stored in a moisture-proof box below 10% RH for moisture-proof storage. And above grade 3, such as grade 4, grade 5, and grade 5a, the humidity must be stored below 5%RH.
2. Dehumidification speed of industrial moisture-proof cabinet. A big difference between the use of moisture-proof cabinets in industry and the use of traditional moisture-proof boxes is the increase in the number of door openings and closings. Traditional civilian moisture-proof boxes generally may not be able to open the door once a day, so there is no requirement for the dehumidification speed. However, the use of industrial moisture-proof cabinets has greatly improved the number of door openings and closings. Therefore, it is necessary for industrial moisture-proof cabinets to have a good dehumidification speed to ensure that industrial moisture-proof cabinets can be in place most of the time. Under the required ultra-low humidity conditions.
3. Civilian moisture-proof boxes mostly use civil temperature and humidity liquid crystal display instruments, which cannot be distinguished normally under humidity lower than 20%RH, and the error is large, and the life of temperature and humidity instruments is generally short, the failure rate is high, and the annual error of temperature and humidity is relatively small. Large, unable to achieve accurate control of the fixed value. In industrial storage, due to the higher and higher requirements for the low-humidity capability of industrial moisture-proof boxes, the importance of display accuracy is even more demonstrated. If a humidity below 5%HR is required, but the display accuracy is -5%RH or higher, then this equipment basically cannot meet the requirement below 5%RH. Generally, the display accuracy of industrial moisture-proof cabinets will be within -3%RH, and even higher to -2%RH.
