Tartaric Acid
-
In the gypsum board manufacturing process, Tartaric Acid is added to the slurry mixture along with other additives to help control the setting time of the gypsum. It works by slowing down the chemical reaction between the gypsum and water, which extends the setting time and allows for a more uniform distribution of the mixture.
Tartaric Acid is a retarder additive that delays the chemical reaction between gypsum and water. It does this by reacting with the calcium ions in the gypsum to form a complex that slows the response between the gypsum and water. This delay in the reaction allows for more time to work with the material during production and can help improve the final product’s overall quality.
In addition to its retarding properties, Tartaric Acid is also used as an additive in gypsum board manufacturing to improve the workability of the slurry mixture. It helps to reduce the amount of water needed in the manufacturing process, leading to a denser and stronger board.
