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.

　　熟石膏陳化過(guò)程的長(zhǎng)短、陳化效果的好壞，與所選用的陳化方式、熟石膏堆積料層厚度、顆粒大孝環(huán)境濕度等都有直接關(guān)系。工業(yè)生產(chǎn)中常用的陳化方式有自然陳化法和機(jī)械陳化法。機(jī)械陳化法要增加設(shè)備，如采用風(fēng)動(dòng)、螺旋冷卻陳化設(shè)備或回轉(zhuǎn)冷卻四川石膏粉，陳化時(shí)間短、效率高，但設(shè)備投資和能耗均高。石膏生產(chǎn)線自然陳化法是靠自然條件來(lái)陳化到達(dá)穩(wěn)定熟石膏質(zhì)量的目的、自然陳化過(guò)程中料層不能太厚，否則陳比作用不平均，冷空氣和余熱的交流不充沛，難以使熟石膏的相變過(guò)程趨于穩(wěn)定，所以，自然陳化時(shí)應(yīng)加以人工攪拌料層。自然陳化周期長(zhǎng)，效果差。環(huán)境濕度大對(duì)加快陳化有利。

　　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.

　　為了進(jìn)步陳化效果，有人提議在熟石膏中參加少量的水強(qiáng)迫陳化，即在燒后的熟石膏中參加少量的的水充沛攪拌．在水的沸點(diǎn)以上使熟石膏吸濕后，再依據(jù)需求停止枯燥。還有向熟打膏噴吹霧狀水而使其陳化的辦法；為了促進(jìn)上述辦法的完成，又提出廠添加氫氧化鈉，氫氧化鈣等石膏助熔劑的辦法。

　　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.
