石膏砂浆收缩膨胀仪使用方法

先将标准棒置于工作台上,拧动调整螺丝使之近似垂直。

将测量框架置于标准棒的顶头,调整螺杆和螺母,使百分表对准零位(或记下百分表之刻度)。

将制作养护好的试件两端擦拭净,然后放置在工作台上,然后把测量框架套在试件上,并左右移动表框,使试件与测量框架的测量头准确地接触,此时即可开始读数,并记录下表盘上的刻度值。

如果实验不是连续进行或实验历时较久后,则在测试前须先在标准棒上校准测量框架。

Plaster shrinkage dilatometer use method
★ First place the standard rod on the workbench and turn the adjustment screw to make it approximately vertical.
★ Place the measuring frame on the top of the standard rod, adjust the screw and nut, and align the dial indicator to the zero position (or note the scale of the dial indicator).
★ Wipe the ends of the cured test piece and place it on the workbench. Then place the measuring frame on the test piece and move the bezel left and right to make the test piece and the measuring head of the measuring frame touch accurately. The reading can be started and the scale value on the lower panel is recorded.
★ If the experiment is not continuous or the test lasts longer, the measurement frame must be calibrated on the standard bar before testing.

 

石膏砂浆收缩膨胀仪使用注意事项:

使用时,忌用手直接与标准棒接触,应持外外套部分,以防止标准棒受人体手温的影响。

仪器用毕后,应将测量框架的测量头和百分表探拭净,并涂以钟表油;测试过程中,应使百分表的测头缓慢而平稳地与试件接触,不允许冲击和碰撞,严禁将百分表测杆顶过A大量程范围,以免影响表的灵敏度和使用寿命。

SP-175 gypsum shrinkage expander use precautions:
★ When using, avoid contact with the standard rod directly by hand, and hold the outer jacket part to prevent the standard rod from being affected by the human hand temperature.
★ After the instrument is used, the measuring head and dial indicator of the measuring frame should be cleaned and coated with watch oil. During the test, the probe of the dial indicator should be slowly and smoothly contacted with the test piece. For impact and collision, it is strictly forbidden to push the dial indicator over the A large range, so as not to affect the sensitivity and service life of the watch.
