ZH1450 comprehensive thermal analyzer Introduction: The ZH1450 comprehensive thermal analyzer mainly measures physical and chemical changes related to heat, such as the melting point, melting heat, crystallization and crystallization heat, phase change reaction heat, thermal stability, glass transition temperature, adsorption and desorption, composition analysis, decomposition, combination, dehydration, additives and other changes of substances for research. characteristic: 1. Equipped with a fully automatic temperature and quality calibration system. 2. Can maintain a constant temperature for 72 hours at any temperature point. 3. It has the functions of drawing step cooling curves and calculating crystallization kinetics. 4. It can complete special data processing such as DTA peak area, enthalpy calculation, data comparison, multiple algorithm calculation of activation energy, glass transition temperature, and comparative method measurement of specific heat; Corresponding software can also be provided in a timely manner based on the calculation formula or method provided by the user. 5. The entire measurement process is automatically completed and automatically plotted. During the process of collecting samples by the system, screenshots can be taken at any time based on the output 6. According to user needs, a constant temperature controller interface and a constant temperature gas chromatography-mass spectrometry connector can be reserved. The constant temperature band has stable performance and can be used for secondary detection of tar and various reaction gases. Temperature control range: 25-450 ℃, temperature control accuracy: ± 0.1 ℃. 7. Vacuum unit interface can be reserved (the instrument itself has vacuum sealing measures). After selecting a vacuum unit, it can reach 2.5 × 10-2pa 8. Reserved interface for exhaust gas treatment unit: The exhaust gas treatment unit consists of a condenser and a gas-liquid separator installed on the exhaust channel of the sealed chamber of the heating furnace. The residue generated by the reaction is discharged through a channel to the condenser for cooling treatment, and then passed through a separator for collection. Technical parameters: Temperature range: Room temperature to 1550 ℃ Temperature resolution: 0.1 ℃; Temperature accuracy: 0.1 ℃ Heating rate: 0.1 ℃~100 ℃/min (customizable) Two temperature control modes for furnace body: 1. Control the temperature rise based on the sample thermocouple 2. The temperature is controlled by the furnace thermocouple, and the two working modes can be switched freely through software settings. TG range: 1mg~200mg (adjustable from 0-5g by replacing the support rod); Resolution: 0.1 µ g; Noise:<0.1 µ g. DTA range: ± 10 µ v to ± 2000 µ v (without range control); Resolution: 0.01 µ v DSC range: ± 1mW to ± 500mW; accuracy: ± 0.1 µ W. Software function: The horizontal axis can select temperature or time as a ruler; The vertical axis can choose absolute weight or percentage as the ruler; Can complete routine data processing for DTA, TG, DTG, and DDTG. Atmosphere control system: using a mass flow controller, the two stable and steady flow gases can be automatically switched during the experimental process, with high accuracy, good repeatability, and fast response speed. It can be customized with an atmosphere control system that is resistant to various corrosive gases. Atmosphere: Inert, oxidizing, reducing, static, dynamic
