sodium tripolyphosphate 中文意思是什麼
-
Hi this thesis, the setting time of various retarders had been tested, in which three retarders with good retarding action, citric acid, sodium tripolyphosphate, bone glue are respectively chosen from three types of retarders, hydroxyl carboxylic acid type, phosphate type and protein type, and the strength and setting time of gypsum added with them are determined. effect of some factors, such as ph value, fineness of hemihydrate, type of gypsum on the retarding action of the retarders is also studied
本文對多種緩凝劑進行凝結時間測試，選擇效果良好的羥基羧酸、無機鹽和蛋白質類型的三種緩凝劑：檸檬酸、多聚磷酸鈉和骨膠，測定它們對石膏凝結時間、強度等宏觀性能的影響，並分別研究ph值、石膏細度和石膏種類等因素對它們的緩凝效果的影響。 -
Through the analyzing the macro - structure to micro - structure, the author considers that retarding mechanism of citric acid is that citric acid and ca in the gypsum form the complexant ion, and hinder the crystallization center of dihydrate crystal bigger ; that of sodium tripolyphosphate is that it combined with ca, hinders the dissolve of hemihydrate. formation and growth of crystallization center ; that of bone glue is the glue - protection and chemical absorption action of active group, which also retards the formation and growth of crystallization center
通過宏觀到微觀的分析，筆者認為，檸檬酸的緩凝作用的原因主要在於檸檬酸與鈣形成絡合離子，影響了二水石膏晶體的晶核長大過程；多聚磷酸鈉與鈣形成某種復鹽，對于石膏晶體的溶解、成核和長大過程均有強烈的阻礙影響；骨膠則在於膠體對半水石膏的包裹和活性基團的化學吸附，使二水石膏晶體的成核和長大困難。 -
