Calcium chloride desiccant is the desiccant with the best hygroscopic effect among all desiccants. It can be applied to life, such as shoes, bags, furniture, electronic instruments, hardware, handicrafts, etc., as well as maritime container transportation, container desiccant, etc. So what is the chemical change process in its absorption process? Will there be leakage?
The moisture absorption process of calcium chloride desiccant is as follows:
1、 Powder before moisture absorption
Calcium chloride itself is white powder inside before moisture absorption.
2、 Start to absorb moisture
Moisture absorption will slowly permeate from the four sides to the middle, and there will be obvious color changes.
3、 Agglomeration occurs
Because when calcium chloride is hygroscopic, it will produce chemical reaction, and slowly harden from powder to caking, which will appear at this time.
With more and more moisture, a semi-fluid state is gradually formed inside the desiccant, and the moisture in the air can still be absorbed at this time.
5、 Solidify into a gel
At this time, the calcium chloride desiccant slowly solidified into jelly like colloidal substances, and the hygroscopic state began to close to saturation, but it could still be absorbed.
6、 Hygroscopic finish
After moisture absorption, the inside is like jelly, with no water and no leakage.
Therefore, calcium chloride desiccant is a safe, non-toxic, environmentally friendly and efficient desiccant.
