石膏粉廠家分享怎么促進熟石膏的陳化！

來源：http://www.wavc.cn 日期：2019-11-15 發布人：

　　從各方面的研討結果來看，固然研討辦法有所不同，但有一點是共同的，即熟石膏經過陳化過程能夠使其中的相變過程趨于穩定，改善熟石膏的物理力學性能，可以正常用于建筑石膏及制品生產。

　　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.

　　熟石膏陳化過程的長短、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、顆粒大孝環境濕度等都有直接關系。工業生產中常用的陳化方式有自然陳化法和機械陳化法。機械陳化法要增加設備，如采用風動、螺旋冷卻陳化設備或回轉冷卻四川石膏粉，陳化時間短、效率高，但設備投資和能耗均高。石膏生產線自然陳化法是靠自然條件來陳化到達穩定熟石膏質量的目的、自然陳化過程中料層不能太厚，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程趨于穩定，所以，自然陳化時應加以人工攪拌料層。自然陳化周期長，效果差。環境濕度大對加快陳化有利。

　　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.

　　為了進步陳化效果，有人提議在熟石膏中參加少量的水強迫陳化，即在燒后的熟石膏中參加少量的的水充沛攪拌．在水的沸點以上使熟石膏吸濕后，再依據需求停止枯燥。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.
