Accompanying drawing explanation
Below in conjunction with accompanying drawing to the further detailed description of the utility model:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
In figure: 1 dialyzate carrier, 2 cement-based material powder thin layer plates, 3 connecting medias, 4 rules, 5 articles holding tables, 6 upper covers, 7 base plates.
Embodiment
As depicted in figs. 1 and 2, a kind of filter paper method measures the device of cement powder dynamic contact angle, cement-based material powder dynamic contact angle is measured based on thin layer capillary dialysis principle, comprise articles holding table 5, containing the container holding dialyzate carrier 1 is placed on articles holding table, connecting media 3 and dialyzate carrier contact, the connecting media be in outside container is held for the A riding over cement-based material powder thin layer plate 2, cement-based material powder thin layer plate is placed on articles holding table, and the size of connecting media meets at least can the overing number cement-based material powder thin layer plate A requirement of holding completely.Between dialyzate carrier and powder thin layer plate, arrange connecting media, object is dialyzate evenly, is stably penetrated on powder thin layer plate, to reach the good object of measurement result repeatability.The A end of cement-based material powder thin layer plate can be any one end.
Connecting media is the good and medium of uniform in material of dialysis, and dialyzate carrier is hold the good medium of dialyzate.Connecting media is individual layer filter paper, two layers of filter paper or multi-layer filter paper.Dialyzate carrier is filter paper.
Measurement mechanism for measuring cement-based material powder dynamic contact angle also comprises for the openable closed case providing enclosed environment is tested in dialysis, and case has transparent roof panels.In figure, case comprises upper cover 6 and base plate 7.
