http://www.iqe.es/en/products/defloc-ceramic-deflocculant-additives WebThe dispersed clay platelets spontaneously form flocs due to the attraction between negative face and positive edge charges. This interaction results in suspension gelation and an increase in viscosity. As a chemical deflocculant is added to flocculated mud, the positive edge charges are covered, and attraction forces are greatly reduced.
WebJul 22, 2024 · The sodium silicate is a thick liquid salt solution that forms a thin skin that, with applied heat, quickly hardens on the surface, encasing the soft and therefore, still malleable, clay cylinder beneath.
