100kN電炭制品抗壓抗折強度試驗機,依據JB/T8133.8-2013,JB/T8133.7-2013和JB/T8133.1-2013設計制作,測定電炭制品抗壓強度和抗折強度性能。JB/T 8133.8-2013電炭制品抗壓強度試驗步驟:電碳制品試樣10x10x10mm,每邊允許誤差±0.04mm。兩相鄰面成直角。角度偏差±15′。試樣平行度公差爲0.04mm。試樣不應有掉邊、掉角、裂紋和凸起等缺陷。試驗時應緩慢加載。試驗速度4mm/min~10mm/min。試驗力加載方向應平行于模壓制品壓力方向,垂直于擠壓制品軸線方向。jnshiyanji;直至試樣完全破裂爲止,讀取破壞力F。
JB/T8133.7-2013電炭制品抗折強度試驗步驟:負荷壓頭刀口半徑4.5mm±0.5mm,支撐刀口半徑1mm±0.5mm。兩支撐刀口應在同一平面內且平行,負荷壓頭刀口應平行于兩支撐刀口,能在兩支撐刀口平行面的垂直方向上下移動,並且位于中間位置。hrjtest;兩支撐刀口間距根據電碳制品試樣調整,抗折強度試樣尺寸10x10x64mm,跨距50.0mm;抗折強度試樣尺寸4x8x32mm,跨距25.6mm;均勻緩慢加載,時間不少于5s,直至試樣斷裂,讀取此時抗折破壞力。
