METHOD FOR TREATING GYPSUM CALCINATION PRODUCT
To provide a method of conditioning stucco, which reduces a level of anhydrite and dihydrate salt in stucco and increases a proportion of hemihydrate.SOLUTION: A method of conditioning stucco comprises the steps of: supplying stucco particles to a reaction vessel, the stucco particles comprising calcium sulphate hemihydrate and/or anhydrite, as well as calcium sulphate dihydrate salt; and conditioning the stucco particles at a temperature of at least 100°C and a humidity of at least 70%. During the step of conditioning the stucco particles, the bulk density of the stucco particles within the reaction vessel is at least 1 g/cm.SELECTED DRAWING: None
【課題】スタッコ中の無水石膏および二水塩の濃度を低減し、半水和物の割合を増加させる、スタッコを調節する方法の提供。【解決手段】スタッコを調節する方法は、硫酸カルシウム半水和物および／または無水石膏、並びに硫酸カルシウム二水塩を含むスタッコ粒子を反応槽に供給するステップと、少なくとも１００℃の温度、少なくとも７０％の湿度でスタッコ粒子を調節するステップと、を備える。スタッコ粒子を調節するステップの間、反応槽内のスタッコ粒子のかさ密度は少なくとも１ｇ／ｃｍ３である。【選択図】なし
