ANALYSIS OF FRACTURES IN DRIED CERAMICS SATURATED WITH SURFACTANT SOLUTIONS

摘要：

　　Main goal of this work was to investigate the effect of surfactants on reduction of material fracture during intensive drying of clay-like materials.The dodecyl sulfate sodium salt (SDS) and the fluoric (FC 4430) surfactants were mixed with different amount of distilled water and used for wetting the clay before forming the samples.The acoustic emission (AE) method was applied to monitor on line the development of crack formation in dried material.It was stated that application of surfactants in a prescribed amount may significantly reduce the drying induced stresses and fractures of the material during intensive drying and in this way to improve the quality of dried products.
