PXZT Silica Gel with competitive price is your best choice.
Fine pored silica gel which is produced in our company is widely used in dehydration and epuration of industrial gas, liquid phase and desiccant. It can also be used as catalyst and catalyst carrier.
silica Gel is a substance used as desiccant, when the beads take up moisture the color will turn tight blue.
Silica gel, composed of solid micro-porous silica beads, are typically used as adesiccant. The numerous, interlocking pores on the beads work by creating a lower vapor pressure than the surrounding air, causing the water molecules in the surrounding air adhere to the silica beads.
Nature :
blue or light blue or small spherical particles that do not dissolve in water. Easy to absorb moisture and will gradually be transformed into pink. Moisture can use the color change direction and humidity. For industrial and household desiccant moisture.
Appearance: Transparent or translucent, glass-like pellet.Average pore diameter: 2.0-3.0 nm.
Specific surface area:650-800m2/gPore volume:0.35-0.45 ml/g.
specific heat:0.92KJ/kg.0C.Thermal conductivity:0.63KJ/m.hr. 0C.Use:Mainly used for drying and moistureproof, may also be used as catalyst carriers, adsorbents, separators and variable-pressure adsorbents, etc.
Sizes: 0.5-1mm, 0.5-1.5mm,0.5-2mm,1-2mm,2-4mm, 2-5mm,3-5mm,4-8mm, silica gel powder,etc.
