The instrument is based on the principle of one-way stable thermal conductivity. When the upper and lower sides of the sample are at different stable temperatures, we measure the heat flow through the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces to calculate the thermal conductivity.It meets the requirements of high precision test of material thermal conductivity of material detection research department.
Instrument reference standard: GB / T3399 " Plastic thermal conductivity test method, Heat protection plate method, GB / T3139-2005 (test method for thermal conductivity of fiber reinforced plastics) (test method for FRP thermal conductivity), GB / 10294-2008 (determination of steady state thermal resistance and related properties of protective thermal plate method), Requirements for the thermal conductivity measurement of extruded polystyrene foam in GB / T 10801.1-2002 (molded Styrofoam) and GB/T10801.2-2002 (extruded Styrofoam (XPS)).Main test plastic, glass, fiber, polyurethane foam, thermal insulation materials, heat insulation materials, etc.It is widely used in colleges and universities, scientific research units, quality inspection departments and manufacturers of material analysis and testing.
