摘要

Process for manufacturing blocks of synergistic products, characterized in that a homogenizing operation is carried out, by means of a mixing machine, of an amount of an absorbent product and a high-power insecticidal substance, of the group comprising dimethyl-dichloro- vinyl-phosphate (ddvp), dimethyl-trichloro-phenyl-phosphorothionate or other phosphorus insecticides, alone or mixed, and even in admixture with other conventional low-vapor-tension insecticides, to which mixed product is added polyvinyl chloride (fvc) ) without plasticizer, depending on the support for the active material, with the possible addition of a coloring substance, a perfume and/or a disinfectant, whereby the insecticide acts as a plasticising agent of the fvc, while the product, absorbent increases the power vaporizing absorbent of that insecticide and of the perfume, deodorant or disinfectant, the said mixture being then applied in an extrusion machine. Use that provides a continuous block of the prepared product, equipped with longitudinal holes through, called to increase the evaporation surface of the active materials it contains, with long persistence, after which and after a cooling action of the continuous block, this is subject of fractioning into expandable portions of suitable length, in which the resulting pieces are subject to final actions impregnation of punching, engraving and packaging.
