- The binder itself should have good fluidity. In general, the fluidity of the binder is negatively correlated with the number of molecular weights, and also has a certain relationship with the distribution of molecular weights.
- The binder has good wettability with the ceramic powder. The addition of the binder can make the powder have a certain fluidity, provided that the two have good affinity and wettability. It can be improved by adding some surfactants (such as stearate, titanate, silane, etc.), the principle is to act as an interface bridge between the powder and the binder, reduce the viscosity when the two are mixed, and improve the fluidity .
- The diversity of binder components, considering the improvement of the fluidity of injection molding and the subsequent degreasing process, the binder composed of multi-component organic substances is usually used. In the degreasing process, the multi-component binder is divided into steps During the process, the component with the lowest melting point is separated from the green body first, forming tiny air bubbles, which is helpful for the discharge of the following binder components.
- The binder system should have good thermal conductivity and low thermal expansion coefficient. In addition, the binder should also be non-toxic and harmless, environmentally friendly, non-volatile and non-moisture absorption, and repeated heating performance. invariant characteristics.
