摘要
Methods and systems are provided for preparing a heat resistance accelerator (HRA) slurry. Also provided are methods and systems for introducing a HRA slurry to an aqueous dispersion of calcined gypsum in a discharge apparatus downstream of a stucco mixer in which the dispersion was prepared. These methods and systems are useful in the production of various gypsum products such as board including wallboard and ceiling tiles.
