Description

technical field [0001] The invention relates to the technical field of heat conduction materials, in particular to a high-temperature heat conduction material, a preparation method thereof and an application in an incinerator combustion chamber. Background technique [0002] The incinerator is a kind of harmless treatment equipment commonly used in the harmless treatment of medical and domestic waste and animals. Its working principle is to use coal, fuel oil, gas and other fuels to burn the objects to be treated in the incinerator at high temperature. Incineration and carbonization. According to its working materials, the combustion chamber of the furnace body is an indispensable part of the incinerator. During the incineration process of objects, the temperature in the combustion chamber of the furnace body will usually be relatively high, and a large amount of heat will be generated in the combustion chamber of the furnace body during the incineration process. A large am...
