Do household appliances need a desiccant to prevent moisture? According to the general situation, refrigerators, freezers, air conditioners and the like are used with desiccant appliances, mainly to prevent moisture and ice capillary blockage and dirty blockage in the system piping.
In addition to the need for moisture resistance in home appliances, most electronic parts require a desiccant. Many circuit boards in electronic products are more afraid of moisture, so they will be dried and stored at the factory to prevent damage from moisture. Most of these products choose silica gel desiccant (transparent round bead particles). Silica gel is the most environmentally friendly and safe desiccant among all types of desiccant. Silica gel desiccant is insoluble in water and any solvent, non-toxic and odorless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. At the same time, silica gel is the only desiccant that has passed the US FDA certification and can be used in direct contact with drugs and food.
There are two types of moisture-proof desiccants for electronic appliances:
The moisture-proof effect of the desiccant should be considered from the drying, its own performance, and the use environment.
