Thermal softening treatment

A proper and detailed analysis would require correctly following the fiow of the molten or thermally softened polymer through the nozzle-sprue-runner-gate system into the cavity. This treatment is a complex and formidable task for the following reasons ... 

Thermal treatment at 250°C and higher (annealing) converts the metastable precipitates to the equhibrium AI2CU precipitates (9), and the product softens.

The book opens with a paper on the structure and composition of wood to define the material under discussion and then considers molds, permeability, wood preservation, thermal deterioration and fire retard-ance, dimensional stability, adhesion, reconstituted wood boards such as fiberboard and particleboard, plywood, laminated beams, wood finishes, wood-polymer composites, and wood softening and forming. A final paper treats the common theme of wastewater management. Only one of the papers presented at the meeting is not included in this volume, and its subject of conventional wood preservation methods is adequately treated in detail elsewhere (e.g., Nicholas, D. D., Ed Wood Deterioration and Its Prevention by Preservative Treatments, 2 vols., Syracuse University Press, 1973). 

A second already mentioned application is the metallization of polymer films. As shown in Fig. 3.78, is the thermal treatment of a TMC-polycarbonate film onto which gold metal clusters were deposited [164], Upon annealing above Tg, the metal particles are in parts sunken into the softened film, thereby reducing the surface roughness. It was also concluded that the embedded clusters were covered with a thin polymer layer.
