LRPY Vacuum Expansion Apparatus Dilatometer
LRPY Vacuum Expansion Apparatus Dilatometer
1.Description:
This instrument is used to measure the expansion and contraction properties of metal materials, ceramics, glass, glazes, refractory materials and other non-metallic materials during the heating and baking process at high temperatures. It can be equipped with either an atmosphere protection system or a vacuum system according to user requirements. The vacuum degree is -0.09 MPa.
2.Standard
GB/T 3810.8-2016 specifies the method for determining the linear thermal expansion of ceramic tiles; GB/T 16920-2015 specifies the method for determining the average linear thermal expansion coefficient of glass; GB/T 3074.4-2016 specifies the method for determining the thermal expansion coefficient (CTE) of graphite electrodes; GB/T 7320-2018 "Test Method for Thermal Expansion of Refractory Products"; GB/T 4339-2008 "Determination of Thermal Expansion Characteristics Parameters of Metallic Materials", etc.
