Temperature effects on degradation

Regarding the mechanical behavior of all plastics, hot and cold temperatures cause softening and stiffening, respectively, as would be expected. For geotextiles, high [Pg.224]

Conf. on Environmental Degradation of Materials in Nuclear Power Systems-VIalet Reactors, Monterey, USA, 9-12 Sept. 1985, American Nuclear Society, pp. 448-55 (1986)... [Pg.1326]

Levels of three individual degradation products and the total amount of degradation impurities were monitored at timepoints of 1, 2, 4, 8, 12, and 24 weeks. Statistical software was used to analyze the data and derive models for the rates of degradation as a function of the temperature and sample water content. The analysis showed that temperature and water content were both significant in their effect on degradation rate (Table 4). The... [Pg.250]

Sande (98) reported that temperature is not expected to affect the absorption of photons as such, and no additional energy is needed for the reaction to take place. However, the temperature will affect subsequent chemical degradative reactions in the usual manner as described by the Arrhenius equation. If a secondary thermal reaction is involved, a temperature effect on the overall reaction quantum yield would be expected. A change in the viscosity of the liquid as a result of increase of room temperature can influence the rate of photochemical degradation. [Pg.361]
