GB／T 8301--2008／ISO 35：2004
6.1.1 Latex container, flat bottomed cylinder, height at least 90 mm, inner diameter 58 mm ± 1 mm, cylinder wall thickness approximately 2.5 mm, inner surface should be smooth
Sliding. Both polymethyl methacrylate and glass containers are suitable.
6.1.2 Mixing device, comprising a vertical stainless steel shaft with a conical shape and a length sufficient to reach the bottom of the latex container (6.1.1). axis
The lower end has a diameter of approximately 6.3 mm and is connected to a smooth stainless steel disc in a horizontal shape at its precise coaxial position
20.83 mm ± 0.03 mm, thickness 1.57 mm ± 0.05 mm. Throughout the entire test process, the mixing speed of the mixing device should be maintained at
At a speed of 14000 r/min ± 200 r/rain, the shaft swing should not exceed 0.25 mm.
6.1.3 Latex container (6.1.1) bracket, the bracket should ensure that the axis of the rotating shaft is concentric with the axis of the latex container, and should also ensure that the mixing disc
The distance between the bottom of the container and the inner surface of the bottom of the latex container is 13 rtlITI ± 1 mm.
6.2 Flat bottomed dish
The transparent diameter shall not be less than (145 ± 20) mm, and the depth shall not be less than 20 ml of Ti, which can meet the requirements of conducting several experiments in the same flat bottomed dish.
6.3 Sharp Rod
A pointed rod made of glass or other materials such as stainless steel, with no required size, as the pointed rod is used to hold a small drop of glue
