What are the bulk density, size and moisture content of the general plastic material?
Among them, the mass of the material has nothing to do with the particle size, but the larger particles have larger volume due to the presence of more voids between the particles. Small particles (powder) to the general packing is very tight, so the smaller bulk density.
The bulk density has something to do with particle size. The larger the particle, the smaller the bulk density of the same composition. This is because the accumulation of material quality, material bulk density = space volume. The bulk density is pseudo density.
Another density, independent of particle size, is the true density.Low-density polyethylene: true density of 0.910 ~ 0. 925g / cm3True density of linear low-density polyethylene 0.917-0.923 g/cm3
