For general silica gel desiccant, we set the effective time in the product within the use period, and the silica gel desiccant that has not been opened and sealed is valid within one year. The use time depends on the environment. The desiccant under high humidity conditions has a different time to absorb moisture than the Silica Gel Desiccant under low humidity conditions. When it reaches its moisture absorption capacity, it stops absorbing moisture.

Silica Gel Desiccant is the most common and widely used desiccant on the market now, so we can identify the quality of the manufacturer. First, we should take out a small package of packaged desiccant and disassemble it to see if the silica gel inside is a piece of desiccant. Good irregular round beads, whether there is a lot of powder or broken beads, and then, just check whether there are any impurities in glass beads. You can take a few packs of samples and keep them for a few days to see if the quality of each pack has increased, and by what percentage, so that we can roughly determine its quality.

Attapulgite mineral desiccant is also a new type of Silica Gel Desiccant that is being vigorously promoted in the market today, so first we can take some samples and observe them with our eyes. Touch it with your hand to see if it is dry, and then you can put it into water. The good quality attapulgite desiccant will heat up and melt as soon as it is put into the water. The poor quality attapulgite desiccant will not melt so fast and unevenly.

Silica Gel Desiccant is an efficient desiccant with a moisture absorption capacity of 200%. The price is relatively high, and it is generally used for moisture-proof special valuables. So how do we distinguish between good and bad quality? First of all, you can see if it is in the form of powder crystals, and if it is a desiccant by hand, it does not form lumps. Finally, you can take some samples and put them in water for testing.
