A proposta deste trabalho foi preparar nanocompósitos de polipropileno/compatibilizante/bentonita, pelo método de intercalação na fusão, utilizando como carga uma argila sódica comercial Argel, fornecida por uma indústria local, purificada e modificada organicamente com um sal quaternário de amônio empregando diferentes métodos de preparação. Ao longo do trabalho foram utilizadas duas matrizes e dois tipos de compatibilizantes: PP H103, PP H401, Polipropileno modificado com anidrido maleico (PP-g-MA) e Copolímero de etileno e álcool vinílico (EVOH), respectivamente. As argilas foram caracterizadas por difração de raios-X (DRX), espectroscopia de infravermelho (FTIR) e análise termogravimétrica (TG) visando determinar o método de preparação mais eficiente para obtenção das argilas organofílicas. Uma vez determinado o melhor procedimento para organofilização, na segunda parte deste estudo, avaliou-se o efeito do tipo e teor de argila organofílica, bem como o tipo e teor de compatibilizante nas propriedades de filmes de polipropileno. De acordo com os resultados preliminares deste estudo, há uma indicação de que os filmes de nanocompósitos PP/PP-g-MA/argila organofílica, contendo 1% de argila organofílica e 15% de polipropileno modificado com anidrido maléico (PP-g-MA) podem ser promissores para o mercado de embalagens e poderão em um futuro próximo serem usados como um novo produto por empresas nacionais.
The purpose of this work is to prepare nanocomposites of polypropylene/compatibilizer/bentonite, by melting intercalation, with a commercial sodium clay – Argel – as filler. This clay was organically purified and modified by different methods, with a quaternary ammonium salt. The clays were characterized by X-Ray diffraction (XRD), infrared spectroscopy (FTIR) and thermogravimetric analyses (TG) to determine the most efficient preparation method. Before that, in the second stage of this study, the influence of the type and contend of organoclay in the properties of the polypropylene films was measured; the same was done for the compatibilizer. The preliminary results indicate that the nanocomposites film with 1% of organoclay and 15% of polypropylene grafted with maleic anhydride show promise as packing materials and may be used, in the near future, as a new product by the national industry.

Texte intégralElectroosmosis removed 20-60% of the water with energy expenditures well below the energy required to vaporize the water. Higher voltages or currents removed more water. Removal rates were increased by the addition of CaCl$ sb2$. The lowest bed height (1 cm) gave the lowest energy of dewatering, but the final water removal was low. For constant voltage experiments with an initial field strength of 2.8 V/cm, bed heights around 2 cm gave the highest water removal. The initial solid content had little effect on the final solid content. The Helmholtz/Smoluchowski theory did not predict correctly the effects of electrolyte concentration, solid content and bed height on the rate of electroosmotic dewatering.

Resumo: O presente trabalho consiste na funcionalização do fluido de perfuração conhecido como bentonita (BN) com grupos funcionais sulfidril (SH) provenientes do reagente 3- mercaptopropil-trimetoxissilano (MPTS) e nanopartículas de prata (NPs/Ag), visando a inibição da biocorrosão por oxidação de bactérias. Para tanto, a argila do tipo bentonita, constituída principalmente do argilomineral montmorilonita, foi modificada através de rota de inserção de organossilano e nanopartículas de prata (NPs/Ag) em sua estrutura, sendo um processo favorecido pelo efeito redutor do grupo tiol, proveniente do silano. As amostras funcionalizadas em concentrações distintas de Ag foram testadas contra a ação da ferrobactéria do tipo Thiobacillus ferrooxidans. Para testar o efeito antibacteriano do material híbrido, utilizou-se metodologia em meio de cultura T&K, onde foi possível medir a capacidade de inibição da oxidação de Fe2+ a Fe3+ por unidade de tempo. O processo de modificação proposto permitiu a manutenção da estrutura original da bentonita, bem como a criação de nanopartículas de prata, cujo efeito antibacteriano inibiu a biocorrosão de Fe2+ obtendo, desta forma, fluido de perfuração funcionalizado com grande potencial de aplicação em obras de perfuração de poços tubulares profundos.
Abstract: This work proposes the functionalization of the drilling fluid known as bentonite (BN) with sulfhydryl functional groups (SH) from the reagent 3-mercaptopropyltrimethoxysilane (MPTS) and silver nanoparticles (Ag/NPs), to inhibit corrosion by bacteria that oxidize metal. Therefore, the type clay bentonite, consisting mainly of montmorillonite clay mineral, was modified through organosilane insertion route and silver nanoparticles in its structure, because this is a process favored by the reducing effect of the thiol group from the silane. Samples functionalized in different concentrations of Ag were tested against the action of ferrobactéria type Thiobacillus ferrooxidans. To test the antibacterial effect of the hybrid material, was used T&K methodology, where it was possible to measure the capacity to inhibit the oxidation of Fe2+ to Fe3+ per unit time. The planned modification process, permitted the maintenance the original structure of the bentonite, as well as the creation of silver nanoparticles, that due to the antibacterial effect, has inhibited biocorrosion of Fe2+, obtained in this way, a drilling fluid functionalized with great potential for application in drilling works of deep wells.
