What is the sphericity of resin?
Ion exchange resins are generally spherical in shape. The percentage of resin particles that are spherical among the total number of particles is called the sphericity ratio. For the exchange column water treatment process, the higher the sphericity, the better; it should generally be above 90%.
Ion exchange resins are generally spherical in shape. The percentage of resin particles that are spherical among the total number of particles is called the sphericity rate. For the exchange column water treatment process, the sphericity should be as high as possible, generally exceeding 90%. The method for determining the sphericity of resin spheres involves first drying the resin at 60°C and weighing it, then slowly pouring it onto the upper surface of a glass tilted at 10° to allow the resin to roll freely downward in a dispersed manner. The resin that has rolled down is then weighed again; the percentage of the latter value relative to the former value represents the sphericity
