General performance
Compliant with GB-T11986-98 Technical Specification for Measuring
the Angle of Rest of Surfactant Powder and Particles.
The product meets the requirements of easy use and maintenance,
safety and reliability, economic rationality, and practical beauty.
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-T11986-98.
Installation of instruments
The guide rod of this instrument bracket is divided into four
adjustable sliding sleeves, starting from the top, which are the
movable sliding sleeve of the mixing device, the fixed sleeve at
the 60 degree taper of the glass funnel, the movable sliding sleeve
at the 10mm discharge port, and the movable sliding sleeve of the
ruler
Release and remove the movable sliding sleeve of the mixing device,
fix the glass funnel through the 60 degree taper and the lower
discharge port through the 10mm fixed sleeve of the discharge port,
and visually adjust it to be perpendicular 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
