LRPY-III High Temperature Vertical Expansion Analyzer Thermal Dilatometer
LRPY-III High-Temperature Vertical Expansion Analyzer Thermal Dilatometer
1.Description:
This instrument is used to test the thermal expansion properties of inorganic materials such as corundum, glass, refractory materials, molding materials, ceramics, glazes, graphite, and carbon, as well as metal products. It provides essential testing methods for scientific research and teaching. It can measure the linear expansion coefficient, bulk expansion coefficient, and plot the corresponding change curves. Detection can be conducted either without load or with load as per requirements.
2.Standard
GB/T 3810.8-2016 specifies the method for determining the linear thermal expansion of ceramic tiles. GB/T 16535-2008: Fine Ceramics - Test Method for Linear Thermal Expansion Coefficient: The Lever Method. GB/T 16920-2015: Determination of the Average Linear Thermal Expansion Coefficient of Glass. GB/T 3074.4-2016: Determination of the Thermal Expansion Coefficient of Graphite Electrodes. GB/T 7320-2018: "Test Method for Thermal Expansion of Refractory Products".
