pecific surface: refers to the surface area per gram of silica gel, including the sum of internal micropore surface area and external surface area
Unit: m2 / g
Pore volume: the total volume of pores per gram of silica gel.
Unit: mg / g (ml / g)
Pore diameter: refers to the diameter of micropore inside silica gel.
Unit: angstrom (A0) or nanometer (nm) 1nm = 10a0
Adsorption capacity: silica gel at a certain relative humidity adsorption of water vapor to saturation, at this time adsorption of water vapor is called adsorption capacity.
Unit:%
Bulk density: the ratio of the mass of silica gel to the volume of space it accumulates.
Unit: g / L
PH value: itself defined as the negative logarithm of hydrogen ion concentration. Silica gel pH value refers to the pH value of silica gel aqueous solution containing a certain proportion after certain conditions treatment.
Specific resistance: it is an indicator of the purity of silica gel. The specific resistance itself is defined as the resistance of the solution at a distance of 1cm. The specific resistance of silica gel refers to the dissolution of water-soluble electrolyte in silica gel after certain treatment conditions, and the specific resistance of solution is measured by conductivity. The higher the specific resistance, the lower the quality of water-soluble electrolysis.
Unit: ohm. Cm (Ω. Cm)
Wear rate: it is an index of wear resistance of silica gel. It refers to the loss of silica gel abrasion under certain conditions.
Unit: %
Non bursting rate in case of water: it refers to an index of water resistance of water-resistant silica gel.
Unit:%
