EXSTAR 7000系列TG/DTA配備的水平橫立式雙秤桿設(shè)計(jì)能夠提供無(wú)偏移的基線,對(duì)于外在環(huán)境所造成的干擾,包括溫度擾動(dòng)、熱流效應(yīng)等因素,它都能有高度的抗干擾效能;此外,在精工的升溫速率控制熱分析(CRTA)系統(tǒng)下,使熱重分析檢測(cè)能夠兼具彈性應(yīng)用的同時(shí),更具備了優(yōu)異的高度效能表現(xiàn)。
TG/DTA 可以測(cè)得以下各項(xiàng)數(shù)據(jù):
- 重量變化
- 相變化
- 成份比例分析Compositional Analysis
- 熔點(diǎn)Melting
- 裂解溫度Decomposition Temperature
- 玻璃轉(zhuǎn)移溫度Glass Transition Temperature
- 熱穩(wěn)定性Thermal Stability
- 氧化誘導(dǎo)時(shí)間 O.I.T.(Oxidative Induction Time)
- 揮發(fā)性測(cè)試Measurement of Volatiles
- 玻璃陶瓷相變化點(diǎn)Phase Transformation and Properties of glass ceramics
- 填充物比例分析Filler Content
- 阻燃性研究Flammability Studies
