硫酸钙; 半水硫酸钙 制备方法及用途

制备方法

转窑煅烧法生石膏经粉碎至l~3 mm后加入间接加热的转窑中煅烧15 min,物料最终温度为140~150℃(煅烧医用石膏为115~125℃)。熟料粉碎,经筛选制得半水硫酸钙。 加压法生石膏经粉碎成15~20rnm后加到高压釜内,在加压,温度约120℃条件下蒸煮约7h,然后在120~220℃干燥,再经粉碎、筛分,制得α-半水硫酸钙

用途简介

用途α型在建筑上用作高强度石膏构件、石膏板、铸造模型及机械加工时的固定胶凝加工件。β型主要用于建筑材料、粉饰石膏构件、石膏塑像、陶瓷、精密机械铸件型模、粉笔、胶凝剂等方面。

硫酸钙; 半水硫酸钙 物化性质

外观与性状:
白色粉末
熔点:
1450ºC
沸点:
330ºC at 760mmHg
存储条件/存储方法:

置于阴凉、干燥的库房中。应防止受潮和雨淋,以避免结块变质。

稳定性相关:

常温常压下稳定,避免强氧化剂。难溶于水(20℃时0.3g/100ml水),溶于酸、铵盐、硫代硫酸钠和甘油。与水混合后形成塑性易浇砌浆体,隔一定时间后硬化成坚固石状体,并伴有微量的体积膨胀及放热。属于气硬性建筑胶凝物质。分α型和β型两种,α型俗称高强度建筑石膏,β型俗称熟石膏或烧石膏。工作中应保护呼吸器官,穿工作服、戴防护眼镜。遵守个人防护措施,工作场所应注意防尘和除尘。
