Production processedit
Selection of forming method and bonding agent
There are many special ceramic forming methods. The forming method should be selected according to the shape of the product in production, and different forming methods require different binders.
Binders can be divided into lubricants, plasticizers, dispersants, surfactants (with dispersant and lubricating functions), etc. To meet the needs of forming, a combination of various organic materials is usually used. When choosing a binding agent, the following factors should be considered:
1) It is a necessary condition that the binder can be wetted by the powder. When the critical surface tension (yoc) or surface free energy (yos) of the powder is greater than the surface tension (yoc) of the binder, it can be well wetted.
2) A good binder is easy to be fully wetted by the powder and has a large cohesive force. When the binding agent is wetted by the powder, a gravitational force occurs between the mutual molecules, and the binding agent and the powder undergo red bonding (one-time binding). At the same time, in the binding agent molecules, cohesion is generated due to the orientation, induction, and dispersion effects (Secondary combination). Although water can fully wet poplar material, water is volatile, has a small molecular weight, and has low cohesion, which is not a good binder.
3) The molecular weight of the binder should be moderate. To fully wet, it is desirable that the molecular weight is small, but the cohesion is weak. As the molecular weight increases, the binding capacity increases. But when the molecular weight is too large, the cohesive force is too large and it is not easy to be wetted, and it is easy to deform the body. In order to help the movement of the chain segments in the molecule, a plasticizer should be appropriately added at this time to make the binder softer and easier to shape while it is easy to wet.
4) In order to ensure the quality of the product, it is also necessary to prevent the mixing of impurities from the binder, raw materials and preparation process, which will cause harmful defects in the product.
In the preparation of raw materials, mechanical methods such as pulverization and mixing are used to coordinate with binders and dispersants to achieve dispersion, and do not contain aggregated particles as much as possible. The binding agent is affected by the type and molecular weight, the properties of the particle surface and the solubility of the solvent, and it is adsorbed on the surface of the raw material particles, and plays a role of preventing the aggregation of the powdered raw materials through the three-dimensional stabilization effect. In the forming process, the binder gives the raw material plasticity, has a water retention function, and improves the strength of the formed body and construction workability. Generally speaking, since the binder hinders the sintering of ceramics, it should be decomposed and volatilized by heating in the debinding process. Therefore, it is necessary to select organic materials that can be easily scattered and removed and do not contain harmful inorganic salts and metal ions to ensure product quality
