As chapas drywall desempenham diferentes papéis de maneira excelente. Conheça alguns modelos e entenda como eles podem suprir suas necessidades.
Hydration of Anhydrite: Gypsum might also form through the hydration of anhydrite (CaSO₄). Anhydrite is often a calcium sulfate mineral that lacks the drinking water molecules existing in gypsum. When subjected to h2o, anhydrite undergoes a hydration response, incorporating h2o molecules into its framework and transforming into gypsum.

Despite the fact that gypsum can kind apparent clear crystals, it always takes place as large white chalky deposits.
