摘要
从真空绝热板(VIP)的绝热机制出发,建立了VIP的使用寿命评估模型,利用该模型对玻璃纤维芯材VIP的使用寿命进行预测。基于Arrhenius定律,建立了VIP的加速寿命模型,通过试验确定加速寿命模型中的参数及VIP的激活能,利用该模型可以预测VIP在不同温度下的使用寿命。通过试验样品的长期跟踪数据来验证两种寿命模型的可靠性。探讨了提高VIP绝热性能及延长使用寿命的方法。本研究工作对VIP关键技术突破及工艺参数优化提供了一定的理论依据和技术支持。
According to thermal insulation mechanism of vacuum insulation panels（VIP）,service life evaluation model of VIP was established and service life of VIP with glass fiber core materials was predicted by the model.Accelerated aging model of VIP was proposed based on Arrhenius law,these parameters of which were determined by aging experiments.In addition,the activation energy of VIP was also obtained.The service life of VIP at different temperatures can be predicted by accelerated aging model.The reliability of two models was verified by the tracking test results of test sample.The methods of improving the thermal insulation performance and prolonging the service life of VIP were discussed.The scientific research work in this paper provides theoretical basis and technical support to optimize key technology and process parameters of VIP.
