I. product introduction:
The oxidative induction time testing machine is a technique of measuring the temperature difference between the material and the reference object at the temperature of the process control, and can also measure the time of the oxidation of the material.
The differential thermal analysis curve is the relationship between the temperature of the sample and the temperature (delta t) with the temperature or time.
In dta test, the change of the sample temperature is caused by the heat or exothermic effect of phase transition or reaction.
Such as phase transition, melt, the change of crystalline structure, boiling, distillation, EVAporation and dehydrogenation reaction, fracture or decomposition reaction, oxidation and reduction reaction, the destruction of the lattice structure and other chemical reactions.
