导热系数是保温材料性能好坏的主要参数。随着我国基本建设事业的发展,科研、设计、生产等单位测定保温材料热物理性能的工作越来越广泛,因此,迫切需要我国自己制造精度高、稳定、可靠的导热系数测定仪。 1974年任务下达给天津建筑仪器厂,经与清华大学热能系、河南建筑工程材料科学研究所协作,仪器设计时参考了国内其他单位的设计方案,在加热板的平度和主、护热板温度自动跟踪等方面做了比较细致的工作,于1979年年底完成了三台“DRP-1型导热系数测定仪”样 Thermal conductivity is the main parameters of thermal insulation material performance is good or bad. With the development of China’s capital construction, more and more work is being done to determine the thermal physical properties of thermal insulation materials by scientific research, design and production units. Therefore, it is urgent for China to manufacture its own thermal conductivity detector with high precision, stability and reliability. In 1974, the task was awarded to Tianjin Construction Instrument Factory. After cooperating with the Department of Thermal Energy of Tsinghua University and Henan Institute of Building Materials, the design of the instrument was designed with reference to the designs of other domestic units. The flatness and main and hot plate Temperature automatic tracking and other aspects of a more detailed work done at the end of 1979 completed three “DRP-1 thermal conductivity detector” sample
