Abstract:

Article Preview

The paper studied the time depended crystallinity in a PE cast during the cooling process in mold. According to the competition theory between crystallization and its decomposition in HDPE polymer, a thermodynamic model and the differential equation for crystallization by cooling HDPE polymer was set up. A deference method was applied to solve the differential equation. The temperature and crystallinity were given in form of contour lines for an axial symmetric thick workpeace, and criterion based on the surface crystallization was proposed to determine the correct stripping time in a casting process. The model and the method are capable of calculating temperature and crystal concentration at any time and any mass point in a cast body, and are helpful for the choice of appropriate casting technology.
