Previous issue date: 2011-06-06 / It presents a new type of insulation for ductwork hot water, which can be used in solar
systems for heating water, which consists of a composite of different compositions
based on plaster, cement and EPS ground, palm and water. This composite has as its
main features easy assembly and manufacturing processes and low cost. Comparative
results will be presented on the tests of materials and thermal tubes proposed. Four
formulations were used to manufacture tubes with three diameters 70, 65 and 42mm. It
was also tested conventionally used for elastomeric foam insulation to 110 ? C, for a
comparative analysis with the composite pipe insulator proposed. It will demonstrate
that the cost of manufacturing of such tubes is competitive with alternative elastomeric
foam tested, but results of the composite tube to the temperature range studied, are
lower. Another drawback of the composite insulator tube is its large mass. It would be
important to test such a composite for greater levels of temperature to a diagnostic
technique competitive with conventionally used insulators. A positive factor of using
the proposed composite-tube would be the recycling of EPS so damaging to the
environment, representing an environmentally friendly application of science / Apresenta-se um novo tipo de isolamento t?rmico para tubos condutores de ?gua
quente, que pode ser utilizado em sistemas solares para aquecimento de ?gua, que
consiste de um comp?sito, de diferentes formula??es, ? base de gesso, cimento , EPS
triturado, dend? e ?gua. Tal comp?sito tem como principais caracter?sticas seus f?ceis
processos de fabrica??o e montagem de baixo custo. Ser?o apresentados resultados
comparativos relativos aos ensaios t?rmicos e de materiais dos tubos propostos. Foram
utilizadas quatro formula??es para a fabrica??o dos tubos, com tr?s di?metros 70, 65 e
42mm. Foi tamb?m testada a espuma elastom?rica convencionalmente utilizada para
isolamento t?rmico at? 110?C, para uma an?lise comparativa com o tubo comp?sito
isolante t?rmico proposto. Demonstrar-se-? que o custo de fabrica??o de tais tubos
alternativos ? competitivo com a espuma elastom?rica ensaiada, por?m os resultados do
teste de resist?ncia t?rmica do tubo comp?sito, para a faixa de temperatura analisada,
s?o inferiores. Um fator positivo da utiliza??o do tubo-comp?sito proposto seria a
reciclagem do EPS t?o danoso ao ambiente, representando uma aplica??o cient?fica
ambientalmente correta
