Abstract

MéTODO E EQUIPAMENTO PARA A EXTRAçãO DO MATERIAL DE ENCHIMENTO UTILIZADO NA FABRICAçãO DE PEçAS DE MATERIAIS POROSOS E NOVOS MATERIAIS POROSOS VIABILIZADOS POR ESTA TéCNICA. Esta invenção trata de um método para se retirar material de enchimento polimérico de dentro de peças que se quer que tenham estes espaços vazios de porosidade. Este procedimento de extração por dissolução, reduz os custos e complicações ambientais e melhora a qualidade alem de prover a peça de uma camada protetora já ao termino do processo de extração do polímero, sendo que a solução do polímero extraído pode ser vendida a outras empresas e gerar abatimento de custo ao invés de ser queimado como no processo antigo para a fabricação de metais porosos. Este novo processo inventado ira gerar uma redução no custo de produção de metais porosos como o Alumínio e viabilizar a produção de peças de metais porosos com pontos de fusão mais baixos e de metais mais reativos como exemplo, os alcalinos, os quais antes não sobreviveriam a etapa de queima do polímero, sendo que, justamente por não queimar o polímero de enchimento e sim dissolver este material delicadamente, este processo viabiliza a criação de novos materiais porosos a base de outros polímeros, sejam eles termoplásticos, termofixos ou elastómeros, ou de cerâmicas, ou de derivados de cimento ou mesmo vítreos. Aqui é apresentado um equipamento desenvolvido para otimizar a produção e a viabilizar em larga escala, sendo que o sistema opera em bateladas. é aqui também apresentado um sistema de produção e comercialização de metais porosos onde a empresa produtora do material poroso fornece em formas padronizadas em de chapas e tarugos, e a empresa produtora da peça final a corta e prensa em estampo para chegar a forma final. Como a porosidade é grande, perder um pouco dela é vantajoso se comparado aos custos de usinagem mecânica e ao tempo requerido, uma prensagem é muito rápida. Antes deste processo, havia a queima de poliestireno que tem suas limitações. Com este novo processo de dissolução do material de enchimento, torna-se possivel aplicar uma vasta gama de pares polímero-solvente a produção de peças porosas sendo que, as reivindicações pedem pelo processo como um todo e algumas das possíveis combinações pois seria muito dificil conseguir listar todas. Há também os novos materiais porosos a base de cerâmicas, polímeros, cimentos e vítreos sendo que as reivindicações pedem pelo processo para a produção com as variações possíveis de pares polímero-solvente e por estes novos tipos de materiais.METHOD AND EQUIPMENT FOR EXTRACTION OF FILLING MATERIAL USED IN THE MANUFACTURING OF POROUS MATERIALS AND NEW POROUS MATERIALS FEASIBLE BY THIS TECHNIQUE. This invention relates to a method for removing polymeric filler material from parts that are intended to have these porosity voids. This dissolution extraction procedure reduces environmental costs and complications and improves quality as well as providing the part with a protective layer at the end of the polymer extraction process, and the extracted polymer solution can be sold to other companies and generate cost savings instead of being burned as in the old process for the manufacture of porous metals. This new invented process will lead to a reduction in the cost of producing porous metals such as Aluminum and make it possible to produce lower melting porous metal parts and more reactive metals such as alkaline, which previously would not survive. The polymer firing step is that precisely because it does not burn the filler polymer but dissolves this material delicately, this process enables the creation of new porous materials based on other polymers, whether thermoplastic, thermoset or elastomer, or ceramic. , or cement or even glassy derivatives. Here is presented equipment designed to optimize production and make it feasible on a large scale, and the system operates in batches. Also presented here is a porous metal production and marketing system where the porous material producing company supplies in standardized sheet and billet forms, and the end-piece producing company cuts and presses it into the final form. As the porosity is large, losing a little of it is advantageous compared to the mechanical machining costs and the time required, a pressing is very fast. Prior to this process, there was burning polystyrene that has its limitations. With this new process of dissolving the filler material, it becomes possible to apply a wide range of polymer-solvent pairs to the production of porous parts and the claims call for the process as a whole and some of the possible combinations as it would be very difficult to achieve. list all. There are also new porous materials based on ceramics, polymers, cements and vitreous and the claims call for the process for production with the possible variations of polymer-solvent pairs and for these new types of materials.
