在研究铁尾矿粉掺入沥青混凝土中的力学性能和路用性能的基础上,分析了铁尾矿粉掺量对沥青胶浆-集料粘附性的影响,并开展了不同铁尾矿粉掺量下沥青混凝土的TG和DSC实验.结果表明,综合不同铁尾矿粉掺量作用下沥青混凝土胶浆基本物理性能指标的变化规律,得到在铁尾矿粉掺量为60%时,沥青混凝土各项指标达到较佳值,且...
TG-DSC通过标样与待测样的能量差进行分析,TG-DTA通过标样与待测样的温度差进行分析。也就是说DTA只能...
至于DSC 曲线,你需要画辅助线,来确定热容变化的基线,然后确定放热,吸热产生的焓变。当然这是一个精确...
The goal of the research was to examine the thermal degradation of pomegranate peel to determine its pyrolytic behavior for bio-energy generation. Initial characterizations (proximate analysis, ultimate analysis, biochemical analysis, and higher heating value) were performed before thermal deterioration to ...
The occurrence and development of CSC can be evaluated by TGA and DSC experimental parameters [28–30]. According to the experimental results of thermal analysis, kinetic calculations are carried out, and the activation energy is held as the basis for identifying the spontaneous combustion tendency ...
However, the exothermic energy of the isomerization reaction of polyisoimides is often so small that it can hardly be detected or analyzed as a function of time using typical thermal analysis techniques like DSC and TG/DTA [6]. Furthermore, the isomerization reaction of polyisoimides may take...
RESULTS: We received 1,061 completed questionnaires from nurses in 12 countries. Participants were mainly female (81%), their average age being 42.69 (SD... TG Payne - 《British Journal of Tuberculosis & Diseases of the Chest》 被引量: 9发表: 1942年 ...
不同加热速率对氧化钪与硫酸铵混合物TG-DSC曲线的影响,结果表明硫酸铵热分解过程分为三段,氧化钪可以降低硫酸铵分解温度,氧化钪和硫酸铵共热可以生成 N H 4 3 Sc (S O 4 ) 3 ,N H 4 Sc (S O 4 ) 2 , Sc 2 (S O 4 ) 3 三种化合物,TG-DSC测试的加热速率过小会忽略细微变化,过大会引起峰...
Karacan and Kok [7] investigated the pyrolysis behavior of crude oils and their SARA fractions using DSC and TG with heating rate 10 °C/min. The weight loss and reaction enthalpies of individual fractions suggest that each fraction contains its individual reaction pathways which are independent...
In DSC the largest cellulose dehydration peak shifts of +39 and +21°C were recorded for DL-tartaric and citric acids. In acids studied, polycarboxylic acids with one or more hydroxyl groups are more strongly interacting with cellulose in the solid state. The strong interactions of these acids...
