性状：
蓝色硅胶分为蓝胶指示剂、变色硅胶和蓝胶，外观为蓝色或浅蓝色玻璃状颗粒，根据颗粒形状可分为球形和块状两种，具有吸湿后自身颜色由蓝色变红色的特性。
用途：
1.主要用于仪器、仪表、设备等在密闭条件下的吸潮防锈，同时又能通过吸潮后自身颜色由蓝变红直观指示出环境的相对湿度。
2.与普通硅胶干燥剂配合使用，指示干燥剂的吸湿程度和判断环境的相对湿度。
3.作为包装用硅胶干燥剂，广泛用于精密仪器、皮革、鞋、服装、食品、药品和家用电器等。

Blue Silica Gel
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 conditions. After absorbing moisture, it turns from blue to red, visually indicating the relative humidity of the given environments.
2. 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. It is widely used as silica gel drier for the packing of precision instruments, leathers, shoes, clothes, foodstuffs, medicines and household
electric appliances, etc.
