The number of stainless steel meshes determines the size of the filler particles

The particle size of the filler is generally graded by the percent number given to it through a certain stainless steel wire mesh. For example, 99.8% of the particles pass through 127.95 mesh (325 mesh) stainless steel mesh. The fineness of this filler is called 325 mesh. Corresponding to the number of stainless steel wire meshes, micrometers are also used to express the fineness of fillers. If the distance between the stainless steel wires constituting the stainless steel wire mesh is 44 μm, the filler through the stainless steel wire mesh can also be referred to as a 44 μm diameter filler. Particles larger than 44um in diameter cannot pass through the stainless steel wire mesh, but particles smaller than 44um can pass through the stainless steel wire mesh and mix together.

Because of this, in fact, the particle size of the filler used is not equal to. There are two requirements for the particle size of the filler: one is the uniform particle size, and the other is the particle size distribution. - The average particle size is generally about 5um, and the maximum particle size is not suitable for exceeding 20um. The appearance of the particles should be smooth. Particles of more than 20 μm will have a bad influence on the quality of the product. The particle size of the filler has a certain relationship with the oil absorption value. The larger particle size and uniform particle size of 8um packing have a smaller overall appearance and a lower oil absorption value. They are easily infiltrated by natural resins and can have a long amount of participation, such as calcium carbonate, dioxygenated silicon and coarse talcum powder.

Fine fillers and fillers with a uniform particle size of 5 μm or less have high surface or surface size and oil-absorbing values. The viscosity of a natural resin system for a given filler mass increases, and the amount of participation is limited, such as clay, Fine talc, precipitated calcium carbonate and so on. The particle size distribution of the particles also has a tight influence on the filler application. If the particle size of the filler particles is spread widely, then the smaller particles can be embedded in the life volume particles, and the medium and constant volume particles can be equally embedded in the larger particles, so that the filler can be arranged more urgently, so that the minimum amount of natural resin is required. You can fill the hole between the particles.
