Which desiccant is better to absorb moisture?

We know that there are many kinds of desiccant, different kinds of desiccant moisture absorption effect is not the same, in this we suggest that according to your own product characteristics, to choose the appropriate desiccant products, rather than blindly the strongest moisture absorption of the best.

Our common, is also the most used desiccant on the market is silica gel desiccant, silica gel desiccant - transparent particles, also with color, that is after special treatment, also known as the color changing silica gel desiccant, excellent silica gel moisture absorption rate at room temperature and humidity environment is about 30%, small particles or is not round, the kind of broken called broken beads, moisture absorption time is relatively fast.

There is a relatively high moisture absorption rate desiccant is calcium chloride desiccant, it is all desiccant in the hygroscopic effect, hygroscopic persistence of a strong desiccant, its hygroscopic rate is usually six or seven times that of silica gel, in shipping containers in the hygroscopic capacity can reach more than 300%. So it is often used for Marine container moisture-proof, after all, the sea due to the large temperature difference between day and night, the environment is seriously humid! It is more suitable for packaging space larger products moisture-proof.

Some food, medicine is not suitable for calcium chloride desiccant, so we in the choice of desiccant, the best according to their own product characteristics to choose the appropriate desiccant, so as to play the purpose of moisture-proof dehumidification.
