摘要

process for manufacturing bricks and structural blocks, sealing and decorative, cast or solid for civil works and their respective formula. This patent application aims at the manufacture of bricks and structural blocks, sealing and decorative, cast or solid to be used in civil works of any kind, belongs to the field of industrial production, produced by thermoplastic injection process or pressing and the state of the art provides for the production of bricks, blocks and related fittings from cementitious, clayey, ceramic and natural silicate mixtures; More specifically, the process for the manufacture of bricks and blocks now being presented initially comprises the treatment of recycled polymeric raw material, passing it through a process of removal of metals, abrasives and other contaminants, and then milling them in the process. The sequence is mixed and homogenized and then passed through a kiln-drying process and then sent to the injection process in a plastic injection molding machine under controlled temperature conditions. If the complementary method is used, using new polymeric raw material, it goes straight to the thermoplastic injection process. The same new or recycled materials may undergo a pressing process to obtain the same structural, sealing or decorative, cast or solid bricks or blocks.
