Thermotropic phase transition material tester

Abstract

The invention discloses an infrared thermo-control phase transition film tester; an infrared thermo-control phase transition film has the following characteristics: below the phase transition temperature point, the infrared thermo-control phase transition film has high infrared ray transmittance property, and above the phase transition temperature point, the infrared thermo-control phase transition film has high infrared ray barrier property, so that by use of the thermotropic phase transition material tester, film interface temperature can be increased or decreased by regulation a power-adjustable infrared radiation source or spraying of a refrigerant via a refrigerant nozzle, film infrared transmittance power and temperature values can be respectively measured by an infrared irradiance probe and a temperature probe, test values are can be displayed by an infrared irradiance and transmittance display unit and a temperature display unit, infrared lamp power is adjustable between 0-275W, infrared ray test range is 760nm-2500nm, and temperature measurement range is 0-100 DEG C. The infrared thermo-control phase transition film tester can measure infrared ray real-time infrared transmittance and temperature values of films, glass, organic materials and other materials at different temperatures, has the function of heating and cooling, and is easy to operate, high in precision, light in weight and low in price.

Description

technical field [0001] The invention relates to a device for testing infrared temperature-controlled phase-change films. The test device can be used to measure the phase-change temperature points of temperature-controlled phase-change films, glass, organic materials and other substances and the infrared transmittance at different temperatures . Background technique [0002] At present, thermal phase change materials have been paid more and more attention in the field of energy saving and emission reduction, and have begun to be applied. However, due to the complexity of performance testing of thermal phase change materials, four-probe testers were mainly used in the past; full-band spectrophotometers or X-ray diffraction and other methods are used for testing, and the testing equipment is expensive and the operation is complicated, which affects the application and promotion of thermally induced phase change materials to a certain extent. The invention has the characteristi...
