开发了一个理论模型来模拟硬质泡沫的聚氨酯发泡过程。在该模型中，通过 MATLAB 求解多个常微分方程，并且该模型能够通过输入泡沫配方信息来预测温度分布。这项关于泡沫建模的初步研究重点是适合作为时间函数的实验温度数据的反应动力学参数。该模型能够准确地模拟单多元醇聚氨酯配方的温度分布，并能够根据纯组分动力学参数准确预测混合物的温度分布。这项工作的主要目标是加快通过模拟开发新泡沫配方的能力，特别是将新的生物基多元醇纳入配方中。 (C) 2013 Wiley periodicals, Inc. J. Appl。聚合物。科学。 130：1131-1138，2013
A theoretical model was developed to simulate the polyurethane foaming process for a rigid foam. In the model, multiple ordinary differential equations were solved by MATLAB and the model was able to predict temperature profiles by inputting foam recipe information. This initial study on foam modeling focusses on reaction kinetic parameters that were fitted to experimental temperature data as a function of time. The modeling was able to accurately model temperature profiles of single-polyol polyurethane formulations and was able to accurately predict temperature profiles of mixtures based on pure component kinetic parameters. A primary goal of this work is to expedite the ability to develop new foam formulations by simulation-especially for incorporation of new bio-based polyols into formulations.
