Title The melting and flowing properties of the thermoplastic
material under the lateral thermal radiation
Abstract
The thermoplastic material is widely used because of its easy and cheap. But now it brings new problem to fire Prevention for its particularity in the fire. The purpose of this work is to research the melting and flowing properties of the thermoplastic material under the lateral thermal radiation. We designed and set up that experimental device. Based on this device, we can research the melting and flowing properties of the thermoplastic material under the different thermal radiation, we demarcate thermal radiation of different section, and different points of the same section. By comparing the melting and flowing of the thermoplastic material, it is concluded that the closer of the distance the faster the melting and flowing getting on while other conditions are the same. When the hole appears, we write down the time , it is not only the faster but also the more serious it is getting on, and the hole is bigger when we cut off the heat. The results show that it is helpful for studying the melting and flowing of the thermoplastic material.
