This kind of silica gel has a blue indicating dye that turns light pink over time to signal when the silica gel is complete and no longer able to absorb moisture until reactivated – infinite reactivation periods are possible.
Under airtight settings, colour-changing silica gel is used to absorb moisture and resist corrosion on instruments, metres, and appliances. Simultaneously, by shifting the colour from blue to red after absorbing moisture, it may directly reflect the relative humidity of the region.
To signify the degree of moisture absorption of the desiccant and assess the relative humidity of the atmosphere, colour-changing silica gel is used in combination with regular silica gel desiccant. Precision tools, leather, shoes, garments, food, medication, and kitchen appliances all use silica gel desiccants as packaging desiccants.
Reactivate the blue silica gel until it has become light pink in colour
Heat the beads for 3-4 hours in an oven at 105° to 115°C. Enable the silica gel beads to cool fully before storing them in an airtight jar before you're able to use them again.
Remarks: Silica gel has a high potential for absorbing moisture. As a result, it should be kept in a dry place. Between the box and the land, there should be a shelf. Please close the packing bag as soon as possible after opening it to avoid air absorption for a prolonged period of time. In the dampness. In regular circumstances, leftover colour-changing silica gel may be stored for one year. During transportation, avoid fog, moisture, and exposure.
