Description

Technical field [0001] The invention relates to a thermal protection material catalytic coefficient testing device and a thermal protection material catalytic coefficient testing method. Background technique [0002] The process of breaking molecules into atoms and rearranging and combining atoms to form new substances is called a chemical reaction. The reaction is often accompanied by phenomena such as luminescence, heat generation, discoloration, and precipitation. The speed of a chemical reaction is usually measured by the chemical reaction rate, which is expressed by the amount of reactant or product in a unit time. The rates of different chemical reactions vary greatly. For example, the explosive reaction is almost instantaneous, while the reaction rate of elemental gold in the air and oxygen is very slow, almost no reaction. Therefore, in order to speed up or slow down the chemical reaction rate, some chemical reaction processes can be carried out as expected. Add a cert...
