Instrumento de condutividade térmica DRH-600

1.Visão geral:

The instrument is based on the principle of unidirectional stable heat conduction. When the upper and lower sides of the sample are at different stable temperatures, the heat flow through the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces of the sample are measured to calculate the thermal conductivity. The instrument is designed for the test of thermal insulation materials with low thermal conductivity, and meets the high precision test requirements of the material testing research department for thermal conductivity of thermal insulation materials. Padrões de referência de instrumentos: GB/T3399-82 “Método de teste de condutividade térmica plástica, método de placa de calor”, GB/T3139-2005 (método de teste de condutividade térmica de plástico reforçado com fibra) (método de teste de condutividade térmica de plástico reforçado com fibra de vidro), GB/10294-2008 (material de isolamento térmico resistência térmica em estado estacionário e características relacionadas à determinação do método de placa quente protetora) e assim por diante. Principalmente testar plástico, vacuum glass, fibra, espuma, pó, glue and other materials. Amplamente utilizado em faculdades e universidades, unidades de investigação científica, quality inspection departments and production plant material analysis and testing.
