JH-II-4 Non-metallic material expansion coefficient tester
Introduction: The coefficient of expansion of non-metallic materials is used to test the coefficient of expansion of non-metallic materials, graphite, ceramics, rubber and plastics and other composite materials at a certain temperature. It can display the displacement change in digital or pointer type. The appearance is vertical to test the expansion coefficient of large-scale materials. technical parameter: 1. Limit furnace temperature: -200-100°C, 1000°C, 1400°C, 1600°C can be selected by customers.
2. Heating rate: 0.1-20K/min can be set, the conventional rate is controlled below 5K/min, special requirements are customized instructions, experimental process control parameters, including PID parameters and online communication methods. Arbitrary adjustments, settings, and locks are realized in the whole process by smart meters. The interface parameter modification is realized by the upper computer (computer). 3. Measuring range and error of expansion value: ±5mm ±0.1%. 4. Temperature control accuracy: ±1℃ temperature record value error≤±0.5﹪; different temperature has different heating elements and different temperature control methods; low temperature uses liquid nitrogen cooling or other cold sources. 5, the resolution of measuring the expansion value: 1um; 6. Sample size: length 50mm (max), diameter: 10-20mm (max), the specification of the sample can be set by the user, and special customization. 7. Test atmosphere: vacuum (10-1Pa), static, dynamic; inert or reactive gas, different vacuum requirements can be customized. 8. Sample state: solid, powder (with special test mold). 9. Sample holder: quartz, alumina, etc. (selected according to the required temperature). 10. The expansion coefficient of non-metallic materials is used to accurately determine the expansion or contraction of large specimen materials during the heat treatment process. It is suitable for testing materials such as ceramics, graphite, building materials, glass, refractory materials, metals or alloys. It can complete the research of thermal expansion coefficient, softening temperature, glass transition temperature, phase transition, density change, sintering rate control (RCS), etc.
