Calcium Hydroxide (Ca(OH)2) or Hydrated Lime
Calcium hydroxide or hydrated lime are products of a chemical reaction between ground CaO and water. They are produced in a mixture tank, ground into powder (170-230 mesh), then put into packages or transferred to bulk trucks, and delivered to customers branded as ‘Rhinoceros’.
The composition and properties of the product, such as available Ca(OH)2, MgO, Fe2O3, SiO2, moisture content, and particle size, vary depending on lime raw material, reaction with water, and production process.
