Product Details

TThe main raw materials of coal-based spherical activated carbon are various wood chips, coconut shells or pitch. The raw materials are relatively wide, spherical in shape, roughly gray-black in color, odorless, and of course non-toxic. The production process is generally carried out by crushing, mixing, spherical, drying, carbonization, and activation. Like other activated carbons, the main feature of spherical activated carbon is its adsorptivity, and its adsorption is mainly divided into two categories: physical adsorption and chemical adsorption. Physical adsorption mainly uses its porous nature to give it a certain specific surface area, thereby producing its strong adsorption effect. Chemical adsorption is mainly due to the fact that coal-based spherical activated carbon is not only composed of carbon, but also has many functions of oxygen and hydrogen. Such as carbonyl, carboxyl, phenols, lipids and other substances, these substances can form chemical bonds with certain substances, and then play a role in what we call chemical adsorption. Of course, coal-based spherical activated carbon not only has the characteristics of adsorption, but also has the characteristics of small particles, high filling degree, good fluidity, high strength, and high wear resistance.
