Blue Silica Gel
AddDate:2012/9/2
Characteristics
Shape: glass-like pellets or lumps. Color: blue or light blue.
Including blue gel indicator, chromotropic silica gel and blue silica gel. Turning from blue to red after absorbing moistures.
Use
1.Mainly used for absorbing moisture, anti-rusting of instruments, gauges and equipment in the enclosed condition. After absorbing moisture, it turns from blue to red, visually indicating the reletive humidity of the given enviroments.
2.When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moisture and judges the reletive humidity of a given enviroment. It is widely used as silica gel drier for the packing of precision instruments, leathers, shoes, clothes, foodstuffs, midicines and household electric appliances, etc. Technical Data
Size:1-3mm, 2-5mm,4-8mm.
Packaging: 25kg per compound bag or 170kg per drum.
Note: Packing and size may be customized per your specific requirements.
Blue silica gel si classified into blue gel indicator, allochroic silica gel and blue gel indicator whose appearance is blue and translucent glassy. As hygroscopic agent, it not only does hygroscopic effect but also shows the hygral change of seal packing space medium through changing into blue along with increasing hygroscopic capacity.
