Discussion on influencing factors of combustion heat value results of low calorific value materials
For some building materials with low calorific value and intended to achieve Class A combustion performance,the combustion heat value is a mandatory item in their evaluation.However,due to the low calorific value of the materials,it is not easy to ignite during the test,and the accurate test results cannot be obtained.Therefore,it is necessary to use manual intervention to make the sample completely burn.Aiming at the crucible test method in the test standard,this paper explores the influence factors in the test process,such as the shape of the sample,the shape of the additive benzoic acid,the relative placement of the above two during the test and their mass ratio,and determines the test methods that help the sample to burn completely.
