Characteristics of differential thermal analyzer
The differential thermal analyzer is an instrument that measures the temperature difference between the substance and the reference substance as a function of the temperature under the program control temperature. It is composed of program control parts, furnace body and recorder, which can be controlled by computer and print test report. The phase diagram of molten salt is an important basis for studying the thermodynamic properties and structure of molten salt, and it is also the basic basis for the selection of electrolytes for molten salt electrolysis, electroplating and molten salt high-energy batteries. Differential thermal analysis is a widely used method to determine the phase diagram of molten salt. It is characterized by simple equipment, convenient operation, high test efficiency and good reproducibility and sensitivity.Differential thermal analyzers can be widely used to determine the characteristic temperature of substances and the heat absorbed or released during thermal reactions, including physical or chemical reactions such as phase change, decomposition, combination, solidification, dehydration, and evaporation of substances. It is widely used in the fields of inorganic, silicate, ceramics, mineral metals, aerospace temperature resistant materials, etc. It is an important instrument for thermal analysis of inorganic, organic, especially high molecular polymers, glass fiber reinforced plastics, etc.

Characteristics of differential thermal analyzer:

1. The instrument heating control system, PID temperature control program, high temperature control accuracy. During the sample collection process, the system automatically changes the range according to the output signal.

2. The perfect two-way voltage stabilization and steady flow atmosphere control system is controlled by a mass flow meter, which can change the gas type in the experiment.

3. The entire measurement process is automatically completed and automatically drawn. The software function can be used to complete DTA conventional data processing; special data processing (DTA peak area, enthalpy calculation, kinetic parameter calculation, data comparison, multiple algorithms to calculate activation energy, glass Chemical transformation temperature, comparison method to measure specific heat, etc.).

4. Users can use indium, tin, lead and other samples to calibrate the accuracy of the instrument's temperature, differential heat, and energy.

5. The automatic temperature control software is powerful and flexible, with a friendly user interface, rich data analysis functions and flexible temperature control program settings.

6. Large-screen LCD display, real-time display of the status and data of the instrument, two sets of thermocouples, one set of galvanic couples display the furnace temperature in real time (regardless of whether the heating furnace is working or not) and the other set of galvanic couples display the sample temperature at work.
