Audited Supplier ORANGE SILICA GEL is a heavy metal free, environmental-friendly humidity indicator SILICA GEL for protection of goods and miscellaneous substances widely USED in Transformer Breathers & Air Dryer in Power Sector.
ORANGE SILICA GEL is an alumino-silicate gel in the form of hard Round Shape or Spherical Beads form, with a very high resistance to crushing and a low attrition rate. Orange Silica Gel has a longer life than most other adsorbents and can reduce operating costs in most applications. It is also known as Nontoxic Indicating Silica gel
Orange Indicating Silica Gel is a spherical/beads type with very high mechanical integrity. The degree of moisture uptake is indicated by a color change from orange to Green & Orange to Colorless at 6 - 8 % weight water absorption. Silica Gel Orange meets the world demand for a heavy metal free and environmental friendly indicating agent.
Orange Silica Gel Available Sizes: 1-3 mm, 2-4 mm, 3 - 5 mm
Non-indicative white silica gel:

Breather
Desiccant
A desiccant is a hygroscopic material used for maintaining dryness. For manufacturers, the purpose of silica gel is to be used as a desiccant. Silica gel also serves to keep the relative humidity inside a system of satellite transmission waveguide as low as possible. In compressed air systems of any industry, silica gel is also used to dry the air. Where a bed of silica gel beads is made for the air from the compressor discharge to flow through it. The silica gel beads are used for adsorbing the amount of moisture present in the air and preventing it from damaging at the point of use of the compressed air due to condensation. A similar kind of system is used for drying the compressed air on railway locomotives.
Water filtration
Silica gel has water absorption properties because of this property it is used in domestic water filters. Some minerals that are dissolved in water can be absorbed by the surface structure of silica gel. Because of the lack of regulations for products of the filtrations of domestic water, no studies give validation to the manufacturer claims regarding the effectiveness of the filtration system of sorbent silica gel.
Humidity indicator
The silica gel changes its colour slowly whenever it is doped with an indicator of moisture as it transitions from the anhydrous state which is a dry state to the hydrated state that is a wet state.
Chemistry
Silica gel in chemistry is applied in chromatography as a stationary phase. This gel is also applied to glass, plastic sheets and aluminium for thin-layer chromatography. Silica gel is also bound to chelating covalently. These materials possess the ability to remove the metal ions selectively from aqueous solutions. Chelating groups are able to make bonds (covalent bonds) to polyamines. This can also be combined with alkali metals and it forms an M-SG reducing agent. Silicon dioxide is not expected to biodegrade in soil and water.
