According to Shenzhen Mingwei Industrial, the color-changing silica gel desiccant is an indicator adsorbent with high added value and high technical content. It is a high-end adsorption desiccant. Its main function is to remind us whether the desiccant absorbs moisture.

Principle of discoloration silica gel desiccant:

The color-changing silica gel desiccant contains cobalt chloride, which is non-toxic and harmless, and has a strong adsorption effect on water vapor in the air. At the same time, it can display different colors by changing the amount of cobalt chloride crystal water contained. The blue color before moisture absorption gradually turns into light red with the increase of moisture absorption, so as to achieve the function of moisture absorption indicator.

It is used in conjunction with ordinary silica gel desiccant to indicate the degree of moisture absorption of the desiccant and determine the relative humidity of the environment.

Because the color-changing silica gel desiccant is indicative, it is widely used in food and medicine, precision instruments, clothing, shoes, and household appliances.

The above is an introduction to the function of color-changing silica gel desiccant. For more desiccant information, please visit: http://www.amingwei.com/
