Through the subsequent 300 s as the platens gradually reached the set target temperature. On top of that, the HDPE films in the surface absorbed power for the duration of the melting procedure, decreasing the surface temperature. At the one-quarter position beneath the mats’ surface, the temperature was much greater than that at the core, and this temperature distinction decreased with time.

Effects of Moisture Content material on Heat Transfer Figure 4 illustrates the effect of moisture content on the core temperature and onequarter position temperature, and no apparent influence was observed. Owing for the closure from the hot press platens, the mat surface temperature swiftly enhanced to 150 in 20 s and may be described applying the Dirichlet boundary condition. The surface temperature continued to improve to 160 for the duration of the subsequent 300 s because the platens gradually reached the set target temperature. Additionally, the HDPE films in the surface absorbed power throughout the melting approach, decreasing the surface temperature. At the one-quarter position under the mats’ surface, the temperature was substantially higher than that in the core, and this temperature distinction decreased with time. The heat was transferred from the greater temperature region to the reduce temperature one particular, and the heat gradually transferred from the surface towards the core.Figure four.
