3.Blue Silica Gel Function
1.Mainly used for absorbing moisture, anti-rusting of instruments, gauges and equipment in the enclosed conditions.
2.After absorbing moisture, it turns from blue to red, visually indicating the relative humidity of the given environments.
3.When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moisture and judges the relative humidity of a given environment.
4.It is widely used as silica gel drier for the packing of precision instruments, leathers, shoes, clothes, foodstuffs, medicines and household electric appliances, etc
Mainly applying field:
Tea Leaf / Foodstuff /Drug/ Dress / Military /Electron /Leather ware/ Art ware/ Furniture etc
