Abstract

The effects of the experimental conditions (sample size, heating rate, static and dynamic atmosphere) were studied on the value of the flash-ignition temperature (T i) obtained with a modified derivatograph able to measureT i simultaneously with the TG, DTG, DTA and T curves. The effects of various parameters are discussed and the optimum conditions determined.T i for bleached cotton fibre was found to be 270±1 °C.

Zusammenfassung

Es wurde der Einfluß experimenteller Bedingungen (Probengröße, Aufheizgeschwindigkeit, stehende und bewegte Atmosphäre) auf den Wert der Entzündungstemperatur (T i) untersucht, welche mittels eines zur gleichzeitigen Messung vonT i sowie der TG, DTG, DTA und T-kurven modifizierten Derivatographen bestimmt wurde. Der Einfluß verschiedener Parameter wurde besprochen und Optimumbedingungen festgestellt. Für gebleichte Wolle wurde einT i-Wert von 270±1 °C gemessen.

РЕЗЮМЕ

Изучено влияние эксп ериментальных услов ий (размер образца, скоро сть нагрева, статическая и динами ческая атмосферы) на з начение температуры вспышки-воспламенения (Тi), измеренной с помощ ью модифицированног о дернватографа, позво ляющего измерятьТ i одновременно с ТГ, ДТГ, ДТА иT-кривыми. Обсужд ено влияние различных па раметров и определен ы оптимальные условия. Найдено, что для отбел енного хлопкового волокна т емператураt i равна 270±1°.
