3. C-type silica gel
[Characteristics] C-type silica gel, also known as coarse pore silica gel, is ivory translucent ground glass, divided into spherical and blocky shapes, with an average pore size of 8.0-10.0nm, a pore volume of 0.80-1.0ml/ g, a specific surface area of 300-400m2/q, a specific heat of 0.92KJ/ kq .℃ and a thermal conductivity of 0.167 kJ/m.
[Main uses] The main raw materials of silica gel cat litter: after further drying and screening, it can be used as desiccant, adsorbent and catalyst carrier; it can also be used as moisture-proof, rust-proof, gas dehydration and purification and catalyst carrier, and can also absorb harmful elements in water; Removing organic acids and polymers from insulating oil; It is also the basic raw material for further processing fine silica gel products. It has large pore size and small specific surface area, and is characterized by high humidity and high adsorption, that is, when the relative humidity is greater than 50%, the adsorption is good; The advantage is that the total adsorption capacity is large, but the disadvantage is that the adsorption is slower than that of type A silica gel.
