锥形量热仪测试固体材料燃烧温度分布的实验装置

在原有的样品燃烧盒基础上稍加改造,结合其特点再设计制作一套固定装置,相互组合成一套完整的实验测试装置。应用锥形量热仪的变热流辐射功率特点以及与多通道数据采集仪相组合,就可以同时把多支测温热电偶安装在样品燃烧盒的固定装置上,对固体板状材料内部温度分布进行测试。这种简捷、有效测定固体材料温度场分布的实验方法。

Experimental Device for Solid Material Combustion Temperature Distribution Test on Cone Calorimeter

In experimental tests,there is no precedent of timely testing and recording of the internal temperature distribution and the temperature gradient for testing materials in the cone calorimeter test function in the heating process.The sample combustion box is too simple,and the thermocouple is easy to loose,which often results in the poor reproducibility of the test data.Therefore,the sample combustion box is slightly modified based on the original sample combustion box.And in view of its characteristics,a set of fixtures was designed to form a complete set of experimental device.Applying the variable heat radiated power characteristics of the cone calorimeter,and combining multi-channel data logger phase,many thermocouples can be installed in the sample combustion box to test the internal temperature distribution of the solid plate material.This simple and effective experimental method for determination of solid materials temperature distribution is an advanced testing technique for the study of combustion,decomposition,weight loss,and the combustion process and mechanism of solid materials.
