What is the dehumidification principle of electronic moistureproof box?

Moistureproof box is simply defined as a metal plate box that can be dried to reduce the humidity in the box; A more complicated definition is the moisture-proof equipment that can keep the humidity in the sheet metal box lower than the external humidity and control it within a certain range.

Define the general storage in moistureproof box: cameras, lenses, lenses, film tapes, tea leaves, cigarettes, books and documents, cigarettes, medicines, leather products, etc. The storage range with stronger moisture-proof performance is wider, and ic, chips, electronic components, precision parts, instruments and meters, antique cultural relics and even seeds can also be stored.

Pay attention to the following points when purchasing moistureproof box:

1. Understand the principle of moistureproof box and know whether the stored items meet the storage requirements of moistureproof box.

I have been engaged in moistureproof box industry for so many years, although the principle of moistureproof in moistureproof box is very simple and easy to understand. But many customers still don't understand. Here I take the refrigerator as an example, and then briefly describe the principle of moistureproof box.

The principle of moistureproof box is the same as that of refrigerator, except that the single function of moistureproof box is to reduce humidity, while the single function of refrigerator is to reduce temperature. The working mode of the refrigerator is that when the outside temperature is 10℃, you need to reach 5℃ in the box, so as long as your refrigerator compressor is not broken, it is no problem to work at 5℃; Then when the outside temperature is-10℃, the cabinet needs to be heated when it reaches 5℃, and the refrigerator has no heating function. This is also the reason why the moistureproof box cannot be higher than the external humidity.

In addition, the customer set the humidity to 30%rh, and the box should work below 30%rh. This is the same as the principle that the car will brake at high speed and the car will move forward for a while.

2, understand whether the storage items need anti-static.

Because moistureproof box is widely used in electronic ic chips and other industries, and the storage of such items needs special attention to anti-static, which also makes it necessary to store these items with anti-static function in moistureproof box. Generally, white is ordinary moistureproof box, and black is anti-static moistureproof box.

3. Understand the specifications of the stored items and the effective volume of moistureproof box.

According to the factory topography, storage product specifications, quantity and other factors, it is best to choose moistureproof box suitable for your own storage size. According to their own storage needs and the reasonable requirements of manufacturers, determine the number of partition layers and the number of cabinet doors.
