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。However, 28 - day strength of concrete increase with amount of tartaric acid and na1p2o7 increase
而酒石酸和焦磷酸鈉在其適宜摻量2倍的情況下，混凝土28d強度略有升高。Influence of sodium hexametaphosphate on dispersion behavior of nano hydroxyapatite in water
六偏磷酸鈉對納米羥基磷灰石水中分散行為的影響In water, the apparent viscosity of composite particles is much lower than that of uncoated graphite with the same solid content ; composite particles have good dispersion effect under different ph value with dispersant agent of sodium hexametahposphate. through the analysis of tg - dtg curve, the oxidation resistance of composite particles has been greatly improved
復合粉體水漿體的表觀粘度比相同質量固含量的未處理石墨大大降低，而且在以六偏磷酸鈉為分散劑時，復合粉體在不同的ph值條件下都取得了很好的分散效果。The effects of five common set - retarders on setting time of cement paste and concrete and strength of concrete are studied. to cement paste, amount of set - retarders added in cement has a critical value
論文分別研究了木鈣、糖鈣、酒石酸、焦磷酸鈉和蔗糖共五種常用緩凝劑對水泥凈漿凝結時間、混凝土凝結時間及強度的影響。分享友人
