The utility model discloses a diamond miropowder finished product quality inspection device's theory of operation is: under the condition of standard water temperature and capacity, a certain amount of diamond micro powder is added for natural sedimentation, so that the sedimentation time is certain under the condition of the same granularity. The fall time of the qualified materials can be obtained through calculation of a formula and accumulation of data, if the fall time of the finished product to be tested is inconsistent with the qualified time, the finished product to be tested can be judged to be unqualified, water washing and other processes are still needed, and the finished product is qualified and is subjected to next finished product operation such as drying and the like only if the fall time meets the requirement.
Derivation of a settling velocity formula of a finished product with qualified granularity: the natural sedimentation classification is to classify the particle size by controlling the sedimentation height and the sedimentation time according to the principle that the particles with the same specific gravity have different sedimentation speeds in the liquid due to different particle sizes. The particles are subjected to three forces in the liquid, namely gravity due to the inherent mass of the particles, buoyancy of the liquid and resistance of the medium to the particles. The settling velocity of the particles is related to the contact area of the particles with the medium, the viscosity of the liquid, the frictional resistance to the movement of the particles in the medium, and the like.
The famous physicist Stokes, in 1851, correctly determined the frictional resistance to which spherical particles move in a medium, and derived the resistance formula (2-1):
Rc＝0.3πμdv (2-1)
in the formula: rcThe resistance to the movement of the spherical particles in the medium;
μ is the liquid medium viscosity (Pa · s);
d is the particle diameter (cm);
v is the sedimentation velocity (cm/s).
When the particles reach equilibrium in solution, i.e. gravity equals buoyancy plus resistance, there are
Another expression (2-2) of the Stokes formula is simplified:
in the formula: g is gravity acceleration (980 cm/s)2)；
Delta is the particle density (g/cm)3)；
Delta' is the liquid density (g/cm)3)；
μ is the liquid viscosity (Pa · s);
d is the particle diameter (cm).
Today, the (2-2) formula is still the theoretical basis for classification and measurement of the granularity of the micro powder internationally.
The density delta of the artificial diamond is 3.52g/cm3Density of the settled liquid water δ ═ 1g/cm3Viscosity μ 0.01Pa · s (293K) and acceleration of gravity g 980cm/s2Substituting into formula (2-2) to obtain
v＝13665.6d2
And the settling time of the finished product with qualified granularity can be converted according to the settling height.
