Thermal conductivity is a physical parameter used to describe the thermal conductivity of a material, and there are many ways to measure it. Some of the commonly used methods include:
1.Thermal conductivity method: This is a method of determining the thermal conductivity by measuring the conductive heat flow of a material. Generally, a heat conduction instrument is used to maintain different temperatures on both sides of the material to be measured, and the conduction power of heat flow through the material is measured, and the thermal conductivity can be obtained by calculation.
2.Hot Plate Method: The hot plate method is a commonly used method for measuring thermal conductivity. In this method, the material to be measured is sandwiched between two hot plates, so that the heat flow is conducted from one hot plate to the other, the temperature and conduction power of the hot plate are measured, and the thermal conductivity can be obtained by calculation.
3.Heat flux meter: The heat flux method is an indirect method of measuring thermal conductivity. In this method, the material to be measured is used as a thermal insulation layer, and the thermal conductivity can be obtained by calculating the change of heat flow through the material.
The above are several common methods for measuring thermal conductivity, each with its own measurement principle and range of use. For specific measurement principles and operation methods, please refer to the instruction manuals and related literature of various measuring equipment.
