Thermal degradation of polymers - Wikipedia

Webb( Thermogravimetric analysis) (TGA) refers to the techniques where a sample is heated in a controlled atmosphere at a defined heating rate whilst the sample's mass is measured. When a polymer sample degrades, its mass decreases due to the production of gaseous products like carbon monoxide, water vapour and carbon dioxide.

Thermal oxidizers are typically used to destroy hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from industrial air streams. These pollutants are generally hydrocarbon based and when destroyed via thermal combustion they are chemically oxidized to form CO2 and H2O. Three main factors in designing the effective thermal oxidizers are temperature, residence time, and turbulence. The temperature needs to be high enough to ignite the waste gas. Most organic … Webb1 okt. 2009 · The thermo-oxidative treatment was performed in an oven using 1.0 g of the milled polymer pellets placed on a glass slide and under an oxidative atmosphere, at 280 ± 10 °C during 2, 5, 15, 30, 60 and 120 min. The experiment was carried out in triplicate. Webb10 apr. 2015 · The thermal and thermo-oxidative degradation was studied under nitrogen and air, respectively at a heating rate of 20 °C/min from room temperature to 750 °C. The temperature of the transfer pipe was set at 215 °C while the TGA–FTIR sample cell was set at 245 °C to prevent the condensation of volatiles in the sample chamber. hyperion latest version

Webb1 juli 2024 · Interestingly, if the same degradation conditions are applied under air atmosphere, the thermo-oxidative degradation produces rheological responses markedly different compared to that observed after thermal degradation (i.e., degradation under nitrogen atmosphere) shown in Fig. 1. In microfabrication, thermal oxidation is a way to produce a thin layer of oxide (usually silicon dioxide) on the surface of a wafer. The technique forces an oxidizing agent to diffuse into the wafer at high temperature and react with it. The rate of oxide growth is often predicted by the Deal–Grove model. Thermal oxidation may be applied to different materials, but most commonly involves t…
