摘要

Invention patent: b "process for the preparation of an absorbent product from a material clay mineral, the product adsorbent thus obtained.Device for applying a princu00ecpio active to an environment or desired location and method for pest control in an environment " d .The present invention relates to a process for the preparation of an absorbent product from a material clay mineral.Can be used for release of an active principle in adsorbed to an environment or desired location.Characterized by the fact that comprises a step of laminating the material clay mineral, followed by a stage of initial extrusion of rolled material and a step of calcining the material ext.Rudado.The product thus obtained is a ceramic product adsorbent granules with low density, with loose density less than 1.10 g / cm3 and with good mechanical strength.With a wear resistance less than 1%.In another aspect the invention refers to a device for release of active principles to a particular environment comprising the product adsorbent of clay mineral described above.
