Estudo das propriedades de transporte de água e íons em tintas de acabamento à base de poliuretana alifática e poliuretana acrílica, novas e após envelhecimento sob radiação UV.
(Universidade Federal de São Carlos, 2005-08-26)
The present work has as objective the comparative study between anticorrosive painting systems with two types of vehicle - aliphatic polyurethane and acrylic polyurethane - loaded with different concentrations of iron oxide ...
Resistência de linha de solda em moldados por injeção de compósitos de polipropileno com talcos e fibra de vidro.
(Universidade Federal de São Carlos, 2003-07-03)
The presence of weld lines in injection moulded reinforced thermoplastics
contributes towards substantial reduction in mechanical properties, due to
unfavourable orientation of the reinforcement in the weak plane of the ...
Análise da superfície de porcelanatos polidos por meio de microscopia de força atômica
(Universidade Federal de São Carlos, 2010-05-24)
The porcelain stoneware tile is a ceramic product that has presented a great increase on production, since it had excellent technical properties and raised aesthetic performance. To improve its aesthetic characteristics, ...
Processamento e transformações de fase em ligas para armazenagem de hidrogênio processadas por moagem reativa.
(Universidade Federal de São Carlos, 2004-07-20)
In the present work, the phase transformations in metallic materials processed by reactive milling were investigated. The as-milled samples were characterized by X-ray diffraction, transmission and scanning electron ...
Desenvolvimento de nanoblendas poliméricas PMMA/SAN
(Universidade Federal de São Carlos, 2012-08-03)
The motivation for this work was the idea that nanoblends are fundamentally dependent on the high interaction between the phases in the mixture. The strategy adopted in this study was based on the use of two polymers that ...
Reciclagem química de PET proveniente de filtros industriais pós-consumo
(Universidade Federal de São Carlos, 2006-03-10)
The PET filter bag is used in the separation of the particulates materials of the gas produced in the aluminum industry. It had been submitted a chemical recycling. Almost industries make the disposal of these materials ...
Tenacificação de polipropileno com elastômeros olefínicos para aplicações com requisitos de transparência ótica
(Universidade Federal de São Carlos, 2011-07-19)
The polypropylene is a versatile polymer but has lack of impact resistance. The polypropylene toughness is obtained thorugh the adition of elastomers that cause the loss of the blend stiffness. Many studies were performed ...
Resistividade elétrica de cerâmicas de alumina a temperatura ambiente e a 600oC
(Universidade Federal de São Carlos, 1992-03-10)
Alumina (Al2O3) ceramic specimens have been prepared via traditional ceramic process, namely, powder analyses, classification and conditioning, uniaxial cold pressong and sintering. DC electrical resistivity measurements ...
Identificação das variáveis que ocasionam a variação de tonalidade utilizando a técnica de decoração por cilindros de silicone gravados a laser
(Universidade Federal de São Carlos, 2015-11-30)
A major problem in the production of ceramic tiles for coating is the variation of
tonality. The determination of their origin within the entire production process and to
minimize its occurrence by the manufacturer is ...
Estudo do método de mistura das suspensões precipitadas (MPS) para a síntese de catalisadores de tungstênio suportado em zircônia (WOx/ZrO2)
(Universidade Federal de São Carlos, 2017-11-16)
Zirconia-supported tungsten oxide (WOx/ZrO2) is one of the main acid catalysts. The development of new methods for its preparation has been widely studied lately. This thesis presents a study of a new synthesis method, ...
