化工部晨光化工研究院一分院研制成功的RJF—D型低温热机械分析仪,在化工部科技局主持下,于84年6月28日在北京通过技术鉴定並定型。该仪器由主体炉子、形变量转换放大器、高低温程序控制器、双笔记录仪等组成,是一台研究高分子合成材料在受力(或不受力)情况下机械形变与温度关系的仪器,可以用来测量材料的平均线膨胀系数、玻璃化温度、流动温度和维卡温度等物性参数。
Ministry of Chemical Industry Chenguang Chemical Research Institute, a branch successfully developed RJF-D low temperature thermal mechanical analyzer, under the auspices of the Bureau of Science and Technology Ministry of Chemical Industry, in June 28, 84 in Beijing through the technical appraisal and stereotypes. The instrument consists of the main furnace, deformation converter, high and low temperature program controller, dual pen recorders and other components, is a study of polymer materials under stress (or force) under the condition of mechanical deformation and temperature of the instrument , Can be used to measure the material’s average linear expansion coefficient, glass transition temperature, flow temperature and Vicat temperature and other physical parameters.
