Application example
Measure physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, crystallization and crystallization heat, phase transition reaction heat, thermal stability of products, curing/crosslinking, oxidation induction period, reaction kinetics, specific heat, etc. Note: the thermal stability test during oxidation induction period is applicable to G B/T 1 7 3 9 1-1 9 9 8.
Instrument principle
Differential scanning calorimetry (DSC) is a technique to measure the power difference between substance and reference under the control of programmed temperature. DSC series differential scanning calorimeter is mainly composed of heating furnace, host, microvolt amplifier, A/D converter, data acquisition system, gas flow control system, computer, printer and other components, supplemented by the switching of two channels of atmosphere, and the measurement results are processed by computer data processing system.
