Silica Gel Blue

Silica Gel Blue semi-transparent glassy substance containing an indicator as “Cobalt Chloride” a heavy metal salt. When free from moisture the Granules or beads are dark blue in colour. As the beads take up moisture, they turn to light blue gradually & When they turn pink, When the gel has absorbed approximately 8 % percent of its weight in water the coloured crystals will turn from blue to pink making an easy visual indicator of whether the gel has become saturated with moisture. It indicates that the gel needs to be replaced or regenerated. The indicating silica gel will still adsorb up to 40% of its weight in water vapour just like the non-indicating In fact, it is mainly used as an indicator for the extent of dehumidification and moisture absorption in the sealed vessel and Silica Gel Breather Industry. Blue Silica Gel is also known as Indicating Silica Gel, Self Indicating Silica Gel, Blue Desiccants, Moisture Absorber.

Blue silica gel regeneration after water absorption

Thermal Heating within temperature limit is very important factor for removal of moisture from BLUE SILICA GEL. Under fully control of electric heating furnace 100-120℃ for blue gel indicator. While other silica gels can be kept in various temperature range, during regeneration should not exceed the following limits:

Coarse porous silica gel should not be higher than 600℃.
Fine porous silica gel should not be higher than 200℃.
Blue gel indicator agent (or discolored silica gel) should not be higher than 120℃.
Silica-aluminium gel must not be higher than 350℃.
The water content of regenerated silica gel is generally controlled below 2% and can be reused.

Dehumidifying and dehydrating agent, air condition, drying of compressed air and other gases, and liquids such as refrigerants and oils containing water in suspension.

One of the most effective adsorbent and desiccant, activated alumina, is a highly porous form of aluminum oxide. Alumina balls are known for their powerful crushing strength and high adsorption rate, which can withstand abrasion and thermal shock. RXSOL BRAND ACTIVATED ALUMINA manufactures activated alumina balls with varying sizes ranging from 1 – 3 mm, 3 – 5 mm, and 5 – 8 mm.

Silicon dioxide, Silica (SiO2), is the best solution for moisture-induced damages caused to products. RXSOL offers Blue, Orange, and White-colored beads in various sizes from 1-3mm, 2-4mm, 2-5mm, 3-5mm, 3-6mm, and 4-8mm. Blue silica gel beads contain an indicator called cobalt, and it is dark blue when it is moisture-free. Silica gel orange beads are used for moisture absorption at the industrial level. White beads have a higher surface area and can absorb more moisture.

RXSOL is a well-known manufacturer of silica gel crystals. We supply blue and white crystals of various mesh sizes from 1-3, 3-4, and 5-8. The blue crystals are semi-transparent and contain cobalt. When they reach maximum moisture absorbing capacity, they turn pink. While silica gel doesn’t contain any indicators, they turn to milky white color when it absorbs moisture.
