Product Description Product DescriptionORANGE 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 gelOrange 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 mmDetailed PhotosIndicative silica gel, orange to dark green:Non-indicative white silica gel:Indicative silica gel, blue to pink:Product Parameters PROPERTIESORANGE SILICA GELChemical CompositionSiO2 - 97%, Al2O3 - 2%, Organic Indicator - <0.01%Color IndicationOrange-Brown-GreenAssay-as SiO297-98%AppearanceSpherical Beads / Round ShapeCHEMICAL PARAMETER:-PH value'4-8Loss on Drying%Max 5 %Adsorption Capacity at 100% humidityMin 30 %Bulk Density800 gm/ltrOrganic Indicator<0.01 wt. %Size3 - 5 mmQualified Ration Partical Size %98 % minQualified Ration of Spherical Partials %95 % min Adsorption CapacityRH=20%Min. 08-09 %RH=35%Min. 13-14 %RH=50%Min. 22-24% Color Variation at RHRH=20%Light Brown to YellowRH=35%Light Brown to GreenRH=50%Light Blackish to GreenPHYSICAL PARAMETER:-Surface Area700 m3/gPore Volume0.4 cm3/gCrush Strength>200 NAttrition Rate>200 NChemical Formula of Orange Silica GelSiO2 + H2O + C25H30ClN3 Advantages & Benefits of Orange Silica Gel :-1Indicating status of silica gel without cobalt chloride.2Non - toxic and non flammable silica gel3Environmental friendly type4Acceptable worldwide especially in European countries.5Higher absorption Capacity at low RH ApplicationsBreatherDesiccantA 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 filtrationSilica 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. ChemistrySilica 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.CertificationsPackaging & Shipping What Our Partners SaidR&D Strength-Lab equipments
