Product introduction:
Blue silica gel is a high-grade desiccant with hygroscopic function and indicates the moisture absorption state through color change. Its main component is cobalt chloride, which has high added value and technical content and belongs to high-grade adsorption desiccant. The appearance of blue silica gel is blue or light blue glass-like particles, which can be divided into spherical and blocky according to the shape of particles.
Ingredients and working principle:
The main component of blue silica gel is cobalt chloride (CoCl₂), and its color changes with the change of moisture absorption. Anhydrous cobalt chloride (CoCl₂) is blue, and the color gradually changes to pink as the moisture absorption increases. This color change makes it an ideal indicator adsorbent.
Product application:
1) Food, medicine and electronic products: Blue silica gel desiccant is widely used in these fields to help protect products from moisture. Its hygroscopic performance is excellent, and it can quickly absorb and lock moisture in a low humidity environment, and intuitively reflect the relative humidity of the environment through color changes.
2) Laboratory and industrial production: In the laboratory, blue silica gel desiccant is used for dehumidification and moisture prevention to ensure the stability of the experimental environment. In industrial production, it also plays an important role in protecting equipment and products from moisture damage.
3) Precision instruments and electronic products: Since blue silica gel desiccant can intuitively display the relative humidity of the environment, it is widely used in the storage and transportation of precision instruments, effectively preventing equipment damage caused by moisture.
