Product Description

abrasive Si3N4 Silicon Nitride ceramic knot nut bolt

Reputation depends on quality, quality comes from Hard!


Silicon Nitride Ceramic:

Dry press forming: The presses of dry press forming technology are hydraulic or mechanical. They can be semi-automatic or fully automatic. The maximum pressure of the press is 200Mpa. The output can reach 15~50 pieces per minute due to the hydraulic press stroke pressure. Uniform, so the height of the pressed parts is different when the powder filling is different, and the pressure applied by the mechanical press varies depending on the filling of the powder, which may cause a difference in the dimensional shrinkage after sintering, affecting the quality of the product, and thus the powder particles during the dry pressing process. Uniform distribution is very important for mold filling.
There are three main parameters for determining the rate of sintering densification. The two main parameters of particle size, viscosity, surface grain size and liquid phase paste are mutually compatible. They do not work in isolation, but rather In order to better combine the liquid phase and the solid phase particles, the liquid phase viscosity should not be too high, and the bitterness is too high. It is possible to reduce the viscosity by adding an additive and improve the wetting ability between the solid and liquid phases, but the viscosity is not too low, so as to avoid When the particle diameter is large, the gravity is too large and the gravity flow deformation occurs, that is, the particle should be limited to a certain range, so that the surface tension is greater than the gravity. Therefore, in liquid phase sintering, fine particle raw materials must be used and the particle size of the raw materials must be reasonably distributed.
