Abstract

The invention belongs to the technical field of measurement molds and methods, and particularly relates to measurement equipment for measuring the thermal conductivity of particles and application and a method of the measurement equipment. The measuring equipment comprises a measuring mold (5) and particles with to-be-measured thermal conductivity, wherein the measuring mold (5) is filled with the particles; wherein the measuring mold (5) comprises a hollow mold body (51) which is vertically through and a bottom plate (52) which is arranged below the mold body (51), the measuring mold is made of Teflon, and the mold body (51) and the bottom plate (52) are designed in a split type or an integrated type. The innovation point of the invention is that the inventor tries to measure the thermal conductivity of the tobacco particles by using a heat flow method, and designs a suitable measurement mold for measuring the thermal conductivity in accordance with the actual application state of the tobacco particles, and the test method is accurate and rapid.

Description

technical field [0001] The invention belongs to the technical field of measuring molds and methods, and in particular relates to a measuring device for measuring the thermal conductivity of particles and its application and method. Background technique [0002] Thermal conductivity is a physical quantity that reflects the thermal conductivity of a material, and represents the thermal conductivity of a material. The thermal conductivity of a material is not only closely related to the types of substances that make up the material, but also to its microstructure, temperature, pressure and impurity content. In scientific experiments and engineering applications, the thermal conductivity of materials used needs to be accurately measured by experimental methods. The test methods of thermal conductivity are divided into two categories: steady-state method and transient method (also known as unsteady-state method). State methods include: hot wire method, probe method, hot plate m...
