Abstract:The thermal deformation Vicat softening temperature tester is mainly used to measure the thermal deformation temperature and Vicat softening point temperature of non-metallic materials(plastic,rubber,nylon,electrical insulating,etc.). This paper studies the calibration method of the Vicat softening temperature tester for thermal deformation,and analyzes the uncertainty of the calibration results of the temperature deviation.

Key words:Vicat softening temperature;heating rate;temperature deviation

熱變形維卡軟化溫度測定儀主要用于非金屬材料,如塑料、橡膠、尼龍、電絕緣等材料的熱變形溫度及維卡軟化點(diǎn)溫度的測定,它由金屬試樣架、裝有負(fù)荷板的負(fù)載桿、壓針頭組件、千分表(位移測量儀器)、測溫儀器、加熱裝置等組成(見圖1)。(剩余2150字)
