YI、TCJT-30型差示掃描量熱儀概述：
TCJT-31型差示掃描量熱儀應用范圍有：對材料氧化誘導時間的測定，高分子材料的固化反應溫度和熱效應、物質(zhì)相變溫度及其熱效應測定、高聚物材料的結(jié)晶、熔融溫度及其熱效應測定、高聚物材料的玻璃化轉(zhuǎn)變溫度等。實驗對象為：固態(tài)、液態(tài)、粘稠試樣，除了氣體。將試樣和參比物分別放入坩堝，置于爐中進行程序加熱，改變試樣和參比物的溫度。若參比物和試樣的熱容相同，試樣又無熱效應時，則二者的溫差近乎為“零”，此時得到條平滑的曲線。隨著溫度的增加，試樣產(chǎn)生了熱效應，而參比物未產(chǎn)生熱效應，二者之間產(chǎn)生了溫差，在DTA曲線中表現(xiàn)為峰，溫差越大，峰也越大，溫差變化次數(shù)越多，峰的數(shù)目也越多。峰頂向上的峰稱為放熱峰，峰頂向下的峰稱為吸熱峰。
Overview of tcjt-30 differential scanning calorimeter:
Tcjt-31 differential scanning calorimeter can be used to measure the oxidation induction time of materials, the curing reaction temperature and thermal effect of polymer materials, the phase transition temperature and thermal effect of materials, the crystallization, melting temperature and thermal effect of polymer materials, and the glass transition temperature of polymer materials. The experimental objects are: solid, liquid, viscous samples, except gas. Put the sample and reference material into the crucible respectively, and then put them into the furnace for programmed heating to change the temperature of the sample and reference material. If the heat capacities of the reference material and the sample are the same, and the sample has no thermal effect, the temperature difference between them is almost "zero", and a smooth curve is obtained. With the increase of temperature, the sample has thermal effect, while the reference material has no thermal effect, there is a temperature difference between them, which shows as a peak in the DTA curve. The larger the temperature difference, the larger the peak, the more times the temperature difference changes, and the more number of peaks. The peak upward is called exothermic peak, and the peak downward is called endothermic peak.
