PZY-III-1417 Non metallic Material Vertical Expansion Coefficient Tester Introduction: This instrument is used to test the expansion coefficient of composite materials such as non-metallic materials, graphite, ceramics, rubber plastics, etc. at a certain temperature. It can display displacement changes in digital or pointer format. The appearance is vertical, which is convenient for testing the expansion coefficient of large sample materials. Technical parameters: 1. Maximum furnace temperature: -200-100 ℃, 1000 ℃, 1400 ℃, 1600 ℃ can be selected by the customer. 2. Heating rate: adjustable from 0.1 to 20K/min, with conventional rates controlled below 5K/min. Customized instructions for special requirements, experimental process control parameters, including PID parameters and online communication methods. The entire process can be adjusted, set, and locked as needed by intelligent instruments. Modify interface parameters through the upper computer. 3. Measurement range and error of expansion value: ± 5mm ± 0.1%. 4. Temperature control accuracy: ± 1 ℃ temperature recording value error ≤ ± 0.5%; The heating elements are different at different temperatures, Different temperature control methods; Low temperature is cooled by liquid nitrogen or other cold sources. 5. Resolution for measuring expansion value: 1um; 6. Sample size: 50mm (max) in length, 10-20mm (max) in diameter. The specifications of the sample can be customized by the user. 7. Test atmosphere: vacuum (10-1mbar), static, dynamic; Inert or reactive gases can be customized according to different vacuum requirements. 8. Sample status: solid, powder (with dedicated testing mold). 9. Sample holder: Quartz, alumina, etc. (selected according to different temperature requirements). 10. Used for accurately measuring the expansion or contraction of large specimen materials during heat treatment, suitable for testing materials such as ceramics, graphite, building materials, glass, refractory materials, metals or alloys. Can complete research on thermal expansion coefficient, softening temperature, glass transition temperature, phase transition, density change, sintering rate control (RCS), etc.
