Some Basic Knowledge of Particle refractory material refractory cementSize Test

Refractory material refractory cement size of the test is an experimental work to characterize the particle refractory material refractory cementsize characteristics of powder by special instruments and methods. The application of powder in our daily life and industrial and agricultural production is very wide. Such as flour, cement, plastics, paper, rubber, ceramics, medicine and so on. Different applications in the powder properties requirements are different, all reflect the powder characteristics, particle refractory material size distribution is an indicator of the most attention in all fields. So objectively reflect the Refractory material refractory cement size distribution of the powder is a very important job. Here I talk about the specific basic knowledge and basic methods about the size of the test.
Basic knowledge, refractory material refractory cement size of the test
1. Particle: geometry has a specific shape in a size range. The refractory material refractory cement size of the general in mm to nano particles, not only refers to the solid particles and droplets, oil droplets and other liquid particles.
2. Hugh: powder composed of particles of different sizes of particles.
3. Refractory material refractory cement Size: the refractory material refractory cement size of particles called particle refractory material refractory cement size.
4. The particle refractory material refractory cement size distribution: reflect with special instruments and methods of the different particle percentage of total powder. The interval distribution and the cumulative distribution of two forms. The interval distribution is also called differential distribution or frequency distribution, it said the percent content of a series of particles in the particle size range. The cumulative distribution is also called integral distribution, it said the percentage is less than or greater than a certain size particles.
The refractory material refractory cement size distribution of the said method
The table: a method by table method particle refractory material refractory cement size distribution, the cumulative distribution of one one listed. The graphic method in Cartesian coordinate system: using histogram and curve representation method for particle refractory material refractory cement size distribution. The function representation of particle  particle refractory material refractory cement size distribution by mathematical function. This method is generally used in the theoretical research. Such as the well-known Rosin-Rammler distribution is distribution function.
