质流仪
摘要：
本发明是有关于一种质流仪，用以量测一水泥系材料的流变性，该质流仪包括：一外桶，用以储置该水泥系材料；一转杆，其一端是伸入于该外桶内；一转速控制器，用以调整该转杆的转速；以及至少一可调式叶片组，其可更换地套接于该转杆，该可调式叶片组具有至少两叶片。本发明借由外桶与可调式叶片组，可调式叶片组为可更换地套接于一转杆，可调式叶片组的半径(r1)与外桶的半径(r0)的比值(r1/r0)是介于0.1～0.6，当转杆的最低转速为0.001rad/s以上，可定速量测其扭矩，如此可大幅减少可调式叶片组的叶片对水泥系材料的扰动，并消除颗粒与叶片间的滑移现象，并同时能以最小的剪应力定义为降伏剪应力。本发明应用于量测水泥系材料的降伏剪应力与粘度，可获得优异的效果。
摘要（英）：

This invention relates to one flow meter to test one concrete materials flow property, which comprises the following parts: one outer barrel to store concrete materials; one rotation bar sticking to outer barrel; one rotation speed controller to adjust the rotation bar speed; at least one adjusting leaf set to change the rotation bar with at least two slices. This invention can change the adjust leave through outer barrel and adjust leaf and the outer barrel diameter r0 is between 0. 1 to 0. 6 to test its torque at minimum rotation speed more than 0. 001rad/s.
