The flow properties of kaolin used for paper coating are very important. Both low-shear and high-shear viscosity measurements are made at 70-71 % solids. Low-viscosity kaolins are required for paper coating because the kaolin coating color must flow easily as it is applied to the paper surface, not leaving streaks or blotches, which can be ...

as Plaster of Paris (POP) [5]. The hardening trend is also normal because gypsum's major role as an additive to cement is usually to prevent flash-setting and thus ensure improved hardness development with time as the hydration processes responsible for hardness proceeds. These desirable effects are usually achieved with small amounts

Properties and Uses of Plaster of Paris Chemistry

Properties and Uses of Plaster of Paris Chemistry

Properties of Plaster of Paris. (i) It is white powder. (ii) When it is mixed with water, crystals of gypsum are produced and set into hard mass. The setting process is exothermic, i.e., heat is evolved. The setting process may be catalysed by sodium chloride while it can be retarded by borax or alum.
