差示扫描量热仪 (差示扫描量热法) is a thermal analysis method to measure the relationship between the power difference and temperature between the input sample and the reference under the programmed temperature control. It is often used to measure the melting heat, crystallinity and isothermal crystallization kinetics parameters of polymers, and to determine the glass transition temperature Tg. Polymerization, 养护, 交联, decomposition and other reactions were studied. The reaction temperature or reaction temperature zone, reaction heat and reaction kinetic parameters were measured.The measurement method of differential scanning calorimeter (差示扫描量热法) is to place the sample in the furnace of the instrument, change the sample through a certain temperature control program, and draw the change curve of the material under the temperature change through the software, and then analyze the corresponding peak value change, obtain the corresponding measurement data, and analyze the characteristics of different materials. The operation is convenient and simple, while the precision is high, the measurement accuracy is high.
