● Compliant with GB-T11986-89 Technical Specification for Measuring
the Angle of Rest of Surfactant Powder and Particles.
● The product meets the requirements of convenient use and
maintenance, safe and reliable, economic and reasonable, practical
and beautiful.
● Installation, debugging, and usage methods of the instrument
● Confirm that the experimental platform for placing this
instrument is in a horizontal state,
● Install the instrument according to the assembly diagram and
technical specifications for measuring the angle of repose of
surface active agent powder and particles in GB-T11986-89.
Installation of instruments:
● There are four adjustable sliding sleeves on the guide rod of the
instrument support. From the top, they are the movable sliding
sleeve of the mixing device, the fixed sleeve at the 60°taper of
the glass funnel, the movable sliding sleeve at the 10mm of the
outlet, and the movable sliding sleeve of the scale
● Loosen and remove the movable sliding sleeve of the mixing
device, pass the glass funnel through the fixed sleeve at the
60°taper and the lower discharge port through the fixed sleeve at
the discharge port 10mm, and make it vertical to the base.
● Place a container with an inner diameter of 100mm and a height of
25mm at the center point with reference to the bottom plate scale
● Adjust the height value between the discharge port under the
glass funnel and the bottom plate by 100mm.
● Adjust the appropriate height visually above the fixed mixing
device and glass funnel, and fix it.
● Complete the test according to the standard requirements
