Introduction to Gypsum Retarder

Gypsum retarder is a crucial additive in the gypsum - based construction materials industry. Gypsum is a widely used building material due to its excellent fire - resistance, sound - insulation, and easy workability. However, gypsum sets relatively quickly after mixing with water, which can be a problem in large - scale construction projects or when complex shaping is required. Gypsum retarders are used to delay the setting time of gypsum, allowing more time for handling, pouring, and finishing of gypsum products. They work by interacting with the gypsum crystals during the hydration process, preventing or slowing down their growth and thus extending the working time of the gypsum mixture.
