The Study of Infrared Heating on PET Bottles by Experiment and Adaptive Finite Volume Method

摘要

Stretch-Blow moulding (SBM) fabricate process is a well known method to produce PET bottles.During the construction procedure,PET surface temperature distribution controlled by infrared heating is the key factor about manufacture technique for the better quality of PET.This paper focuses on how to measure and estimate temperature distribution on the surface of semi-transparent polymers so that we can make sure the proper position and intensity of the infrared lamb.We use infrared camera to detect the real temperature distributions and C++ object-oriented programming to estimate the infrared radiation (IR) results by adaptive finite volume method (Adaptive FVM).The numerical results have been compared with experimental results and the consequence is satisfied.Multiple lambs' cases and the interior temperature distribution in PET will be discussed in future.
