Product name:
Color-variable silica gel
According to different color can be divided as:
Blue silica gel (PY-BLUE), including:
(1). Spherical blue gel
(2). Granular blue gel
Color-variable silica gel, including:
(1). PY-P (purple particle, raw material Alumina silica gel)
(2).PY-O (orange particle, raw material type A silica gel)
Properties: With silicon dioxide as the chief ingredient, the product color varies as humidity changes: after adsorb the humidity, blue particles will change to light blue till the end to light red; purple particles will change to light orange-red till the end to light orange-yellow; orange particles will change to light brown-green till the end to light blackish-green.
Characteristics:
(1). Blue silica gel contains cobalt chloride. After absorbing moisture, it turns from blue to red, visually indicating the relative humidity of the given environments. So the product can be used as industry and household moisture absorption desiccant.
(2). Color-variable silica gel performs all the functions of blue silica gel, does not contain cobalt chloride and is therefore innocuous and pollution-free
Mainly used:
For drying and indicating humidity.
In precision instruments, medicine, petrol chemicals, foodstuff, clothing, leather, electric appliances, other industrial gases, etc.
Sizes: 1-3mm、2-5mm、3-5mm 、3-6mm
