Electronic instruments can be protected from moisture by desiccant. There are two kinds of desiccant for electronic products on the market.

1, silica gel desiccant

2, montmorillonite desiccant

The moisture-proof effect of desiccant should be considered from the aspects of dryness, performance and use environment, and the following points should be considered in the selection of desiccant electronic products:

1. The selected desiccant is not corrosive.

2. The selected desiccant is not easy to produce dust.

These two points are very important. When desiccant is used in electronic products, it is usually placed in a packaging bag. Because the working environment of desiccant is relatively sealed at this time, the use effect is better.
