From the research results of various aspects, although the research methods are different, there is one thing in common, that is, the aging process of gypsum plasters can make the phase change process stable, improve the physical and mechanical properties of gypsum plasters, and can be normally used in the production of building gypsum and products.

　　熟石膏陈化过程的长短、陈化效果的好坏，与所选用的陈化方式、熟石膏堆积料层厚度、颗粒大孝环境湿度等都有直接关系。工业生产中常用的陈化方式有自然陈化法和机械陈化法。机械陈化法要增加设备，如采用风动、螺旋冷却陈化设备或回转冷却四川石膏粉，陈化时间短、效率高，但设备投资和能耗均高。石膏生产线自然陈化法是靠自然条件来陈化到达稳定熟石膏质量的目的、自然陈化过程中料层不能太厚，否则陈比作用不平均，冷空气和余热的交流不充沛，难以使熟石膏的相变过程趋于稳定，所以，自然陈化时应加以人工搅拌料层。自然陈化周期长，效果差。环境湿度大对加快陈化有利。

　　The length of the aging process and the effect of the aging are directly related to the selected aging method, the thickness of the accumulated material layer of the gypsum, and the humidity of the environment. Natural aging and mechanical aging are commonly used in industrial production. The mechanical aging method needs to increase equipment, such as wind-driven, spiral cooling aging equipment or rotary cooling of Sichuan gypsum powder. The aging time is short and the efficiency is high, but the equipment investment and energy consumption are high. The natural aging method of gypsum production line relies on natural conditions to achieve the purpose of stabilizing the quality of hydrated gypsum. The material layer should not be too thick in the process of natural aging. Otherwise, the effect of aging ratio is uneven, the exchange of cold air and waste heat is not sufficient, and it is difficult to stabilize the phase transformation process of hydrated gypsum. Therefore, the material layer should be artificially stirred during natural aging. The natural aging period is long and the effect is poor. High humidity is good for aging.

　　为了进步陈化效果，有人提议在熟石膏中参加少量的水强迫陈化，即在烧后的熟石膏中参加少量的的水充沛搅拌．在水的沸点以上使熟石膏吸湿后，再依据需求停止枯燥。还有向熟打膏喷吹雾状水而使其陈化的办法；为了促进上述办法的完成，又提出厂添加氢氧化钠，氢氧化钙等石膏助熔剂的办法。

　　In order to improve the aging effect, it is proposed to take part in a small amount of water forced aging in the gypsum plaster, that is to say, take part in a small amount of water sufficient mixing in the burnt gypsum plaster, and make the gypsum plaster absorb moisture above the boiling point of water, and then stop boring according to the demand. In order to promote the completion of the above method, the method of adding gypsum flux such as sodium hydroxide and calcium hydroxide is put forward.
