crystal gypsum 中文意思是什麼
crystal gypsum
解釋
結晶石膏-
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。 -
Results of experiment show that the reason of strength decreasing of gypsum added with retarders is that the retarders reduce the supersaturation of liquid phase, and makes the crystal grain largen, and pore is followed to worsen, which lead to the strength drop to a large degree
實驗結果分析表明：在摻加緩凝劑后石膏硬化體強度下降的原因在於緩凝劑降低了石膏的液相過飽和度，使結晶顆粒變大，使石膏的孔結構惡化，最終導致了宏觀強度大幅度下降。 -
The scanning electron micrographs and the data of pore structure of gypsum and gypsum with the retarders also make us known the influence of retarders on the crystal morphology and pore structure, from which transformation of microstructure induced by retarders and the reason of which makes the strength drop a re analyzed. combined with the xps spectrum, the mechanism of action with the retarders are finally proposed
繼而通過對孔結構和石膏硬化體晶體掃描電鏡照片的觀測，獲得緩凝劑對石膏硬化體晶體形貌的影響和對孔結構的改變的信息，分析緩凝劑的帶來石膏的微結構的變化，以及摻加緩凝劑帶來石膏強度下降的原因所在。
