Our orange silica gel indicator is not impregnated with

cobalt chloride, it is the latest product that can replace

the blue silica gel indicator. The composite dyeing agent

without pollution to the environment has been successrully

adopted during the manufacturing process of the orange

silica gel indicator. In this way , it has prevent the

cobalt chloride from polluting the environment from the

very beginning.

orange silica gel indicators have much more adsorption

capacity than that of the blue Indicating silical gel. The

orange silica gel Indicator has won unprecedented

acknowledgement and praise from the clients since its

introduction in European and American markets.

Characteristics
1. Since the collid grains are minute (10-20nm) and have relatively large specific surface area, the grains themelves are colorless and transparent , so they do not affect the natural color of the materials to be covered.
2. With low viscosity, it can soak the places where water soaks, therefore, if presents excellent dispersion and permeability when being mixed with other substances.
3. When the moisture contained in silica sol are evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between ***** is a good adhesive.
Use:
1. Used as the cohesive agent for various fireproof ***** has high bonding strength and high heat-resisting performace(1500-1600℃), etc.
2. Used in coating ***** makes the paints ***** also possesses features, such as anti-contamination, dustproof, anti-aging, fireproof, etc.
3. Used in precision casting of thin covers to increase the cover trength, improbe the casting smooth ***** molding quality is better than that of water ***** can be used to replace ethyl silicate for molding so as to reduce the costs and help improve the operating conditions.
4. Having large specific surface area, silica sol can be used for making catalst and as catalyst carrier.
5. Used in paper-making ***** be used as the anti-glutinous agent of cellophane, pre-treatment agent of photegraphic paper, skidproof agent of cement bags, etc.
6. Used as sizing agent in textile industry.when used with oil agent to process wool and rabbit hair, it helps improve the processing of wool and rabbit hair, reduce broken ends, eliminate flyings, thus improve the finished product rate and increase the ecomomic returns.
7. Used as the treatment agent of silicon steel plates, dispersing agent of kinescopes and skidproof agent of floor waxes, etc.
