Average particle size
That solid particles dispersed in a group-scale geometry.
Can be calculated through a variety of mainly arithmetic average, geometric average, to reconcile the average size and average quality of the average law.
Average particle size of said particles has the following methods:
Linear average diameter: average diameter of a simple linear
Length than the average diameter of the area: there is the same surface area and diameter than the average diameter of particles
The average diameter of the area: its surface equal to the average particle surface area of all particles of average diameter of particles
Volume average diameter: particle size and have the same number of average diameter
Sauter mean diameter: there is the same size and surface area ratio of the average diameter of particles
The quality of the average diameter: diameter at the above or below the cumulative percentage of the same quality (50%)
What is meant by "the size of the average diameter D (4.3)":
Refers to the particle size and shape of the particles the same as the total volume (weight) the same particles, but a hypothetical particle size uniformity of the particle size particle size.
What is meant by "average Sauter diameter D (3.2)":
Refers to the particle size and shape of the particles the same as the total volume (weight) the same, with a total surface area of the same size and uniform particle size of a hypothetical particle size.
1, the average particle size is defined as: di = ΣdiXiΣXi = D (K +1, K) K = 3 that the volume of express 2 surface area, said one length, that the number of 0. Therefore, table 1 D [4 , 3] are the size of the distribution of average diameter
2, the average particle size is the size of the average particle size due to the value in engineering design often used to calculate the heat transfer area of computing from the next. D = 0.1 1d21 + 2d22 +. ... + nd2n where: d1. ... Dn - sub-sieve particles of average particle size at all levels
3, the average particle size refers to the so-called accounting for more than 50% weight of the particle size can be. With such a one or two or more components of the annealing-based release agent to add some useful anti-corrosion agents harmless
