DISPERSANTS When producing ceramics, energy costs have a considerable share in the overall expenses of the final product. Deflocculants help to save water and energy resources, increasing the production output. The slip properties (viscosity, thixotropic behaviour, structural viscosity, dilatancy, rheopexy and Newtonian flow behaviour) can be adjusted according to the customer’s requirements.
The efficiency of the pressure casting process, as well as the cost effectiveness of conventional slip casting, are dependent on the output per unit time, which in turn depends on the casting rate. The use of filtration agents leads to the agglomeration of fine particles, and a more even de-watering of the casting slip is the result. A regular density and a uniform shrinkage allow the production of a homogeneous cast that is free from internal stresses. Separation and sedimentation phenomena are prevented significantly. Furthermore, filtration agents confer good interlocking at transitions from hollow casting to core casting, and better removal from the mould.
Biocides are required for the application of organic additives and/or raw materials to counteract their deterioration caused by micro organisms such as bacteria, yeasts or fungi, and consequently to guarantee long-term stability.
An increasing use of robots and the production of complicated geometries have lead to a growing demand for improved component strength. For this purpose, our temporary binders are employed to increase the green strength, dry modulus of rupture and edge strength.
