Silica gel desiccant should be the most common and widely used Moisture absorber refill tab on the market now. Then we can identify the quality of the Moisture absorber refill tab manufacturer. First, we should take out a small package of packaged desiccant and take it apart. Check whether the silica gel inside is a good irregular round bead, is there a lot of powder or broken beads, and then, just check whether there are any impurities in the 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 Moisture absorber refill tab that is 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.

Calcium chloride desiccant is an efficient biochemical Moisture absorber refill tab 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.
