mso-hansi-font-family:"Times New Roman"">混凝土回弹仪钢钻 "Times New Roman"">回弹仪标准钢钻
mso-hansi-font-family:"Times New Roman"">一、用途:
mso-hansi-font-family:"Times New Roman"">回弹仪标准钢钻是对混凝土,砂浆,砖等回弹仪进行校验的检验工具。
mso-hansi-font-family:"Times New Roman"">二、混凝土回弹仪钢钻概述:
mso-hansi-font-family:"Times New Roman"">回弹仪标准钢钻各部件由优质钢及优质工具钢制成。砧芯与砧体的配合面【莫氏锥度4 mso-hansi-font-family:"Times New Roman"">号】经精细研磨而成,砧心面硬度为HRC58-62。
mso-hansi-font-family:"Times New Roman"">三、使用方法:
mso-hansi-font-family:"Times New Roman"">回弹仪标准钢钻一般放置在水平面上校验回弹仪,回弹仪垂直向下作弹击实验,校准回弹仪的率定值。混泥土回弹仪在本刚砧上作弹击实验 "Times New Roman"">的平均率定回弹值为【N "Times New Roman"">】=80+2;砂浆回弹仪在本刚砧上作弹击实验的平均率定回弹值为【N mso-hansi-font-family:"Times New Roman"">】=74+2 "Times New Roman"">。
mso-hansi-font-family:"Times New Roman"">四、混凝土回弹仪钢钻注意事项:
mso-hansi-font-family:"Times New Roman"">回弹仪标准钢钻作为检验工具,被弹击试验5000 mso-hansi-font-family:"Times New Roman"">次-8000 "Times New Roman"">次后,可将砧芯连同砧体在平面磨平整再用,但砧芯硬度仍需保持HRC58-62 "Times New Roman"">,否则不得再用。回弹仪标准钢钻HB-59 "Times New Roman"">。
mso-hansi-font-family:"Times New Roman"">五、存放:
mso-hansi-font-family:"Times New Roman"">钢砧平时保存在干燥防尘处,以防锈蚀,弹击试验面不得随意磕碰, mso-hansi-font-family:"Times New Roman"">以保证检验工具的标准状态。
