Construction Materials Fire Resistance Thermal Conductivity Testing
Equipment
Scope of application:
Thermal conductivity of dry test pieces of clay and sand, the
thermal resistance of the sample should be greater than 0.1m2.K /
W.
A thermal flow meter is used to detect the thermal conductivity and
thermal resistance of clay, sand, etc., and the computer is used to
realize automatic detection and generate an experimental report.
The instrument adopts a stable hot surface temperature on the side
of the sample, and the heat is transferred to the cold surface
(room temperature) through the sample, and the transferred heat
flow is measured to calculate the thermal conductivity and thermal
resistance. Specially equipped with geotechnical sample cylinder
and specific heat capacity test device, which can be used for
thermal conductivity analysis and specific heat capacity
determination of clay, sand and other soils.
