性狀：
藍色硅膠分為藍膠指示劑、變色硅膠和藍膠，外觀為藍色或淺藍色玻璃狀顆粒，根據顆粒形狀可分為球形和塊狀兩種，具有吸濕后自身顏色由藍色變紅色的特性。
用途：
1.主要用于儀器、儀表、設備等在密閉條件下的吸潮防銹，同時又能通過吸潮后自身顏色由藍變紅直觀指示出環境的相對濕度。
2.與普通硅膠干燥劑配合使用，指示干燥劑的吸濕程度和判斷環境的相對濕度。
3.作為包裝用硅膠干燥劑，廣泛用于精密儀器、皮革、鞋、服裝、食品、藥品和家用電器等。

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.
