Blue self-indicating silica gel、Color-variable Silica Gel and Non Cobalt Color-variable Silica Gel

Executive standard:National chemical industry standardHG/T2765.4—2005.

秒速时时彩 Principle: Suitable for silica gel as raw material, made by the leaching of cobalt chloride blue gel indicator, color silica gel and other process of cobalt free color silica gel。

Appearance: The color of the corresponding varieties expressed.

Character: blue silica gel with Co salt. Performance and application are generally the same as the pores spherical silica gel and can display indicating humidity. Under the dry condition is blue or light blue, with the increase of moisture adsorption, gradually turned into pink. At 20% relative humidity is usually blue or light blue, while 35% it is purple, and when 50% , the color is pink.

Use: Blue gel indicator is mainly used to indicates the degree of saturation and desiccant seal packing materials, precision instruments and meters of space within the medium relative humidity。

Allochroic silica gel is mainly use desiccant and indicator for general instrument and meter of seal packing materials and moisture。

Co-free allochroic silica gel usually work as substitution for Blue gel indicator and Allochroic silica gel.

All three of these products are suitable for the power industry, power plants, transformer factory and repair shops) of transformer thermal siphon device room air breathing apparatus, and the color shows different degree of moisture absorption。

Suitable for in the laboratory, laboratory reagent, moisture absorption effect, and the color shows different moisture absorption rate.
