Definition and difference of wet real density and wet apparent density of resin?
The cation resin is often more humid than the anion resin.Apparent density: the accumulated density of a resin when it expands sufficiently in water. This value is generally between 0.6 and 0.85.
Resin usually refers to softening or melting range after heating. When softening, it tends to flow under external force. At normal temperature, it is solid, semi solid, and sometimes liquid organic polymer. Broadly speaking, any polymer compound that can be used as plastic material for processing raw materials is called resin. Resin is the main raw materials for the manufacture of plastics, paint is also used the system (the main film-forming material, coating such as alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in the Yangtze River Delta and Pearl River Delta are also relatively strong in the paint industry, such as Changxin chemical, Nuplex resin, three resin, Ying DSM syntech resins), adhesives, insulating material, synthetic resin in industrial production, is widely used in separation and purification of impurities in liquid, with macroporous adsorption resin, ion exchange resin, and some special resin.
Wet density: the density of resin particles when a resin expands sufficiently in water. This value is generally between 1.04 and 1.3.
