Abstract

General conclusions are made based on the results of experimental and theoretical investigations of the decomposition kinetics of various polymeric materials in a wide range of heating rates. It was found that the decomposition process of the investigated materials proceeds within confined temperature intervals. Kinetic equations are suggested to describe the thermal decomposition processes of polymers and natural coals, based on the characteristic revealed.

Zusammenfassung

Aus den Resultaten experimenteller und theoretischer Untersuchungen der Zersetzungskinetik verschiedener polymerer Materialien in einem weiten Bereich der Aufheizgeschwindigkeit wurden allgemeine Schlussfolgerungen gezogen. Es wurde festgestellt, dass die Zersetzungsprozesse der untersuchten Materialien innerhalb begrenzter Temperaturintervalle verlaufen. Kinetische Gleichungen zur Beschreibung der thermischen Zersetzungsprozesse von Polymeren und natürlichen Kohlen werden vorgeschlagen, die auf den ermittelten charakteristischen Daten beruhen.

Резюме

Дано обобщение резул ьтатов экспериментальных и теоретических иссле дований кинетики терморазло жения ряда полимерны х материалов в широком диапазоне с коростей нагрева. Установлено, что процесс терморазложения исс ледованных веществ п ротекает в ограниченных темпе ратурных интервалах. Предложены кинетиче ские уравнения для описания процесс ов терморазложения п олимеров и природных углей с уче том обнаруженных закономерностей.
