Redução da inflamabilidade da madeira de Pinus elliottii modificada com partículas de TiO2

Abstract: RESUMOA madeira é um material formado basicamente por polímeros, os quais são pouco resistentes a altas temperaturas e suscetíveis ao fogo. Em aplicações é desejável que esta madeira tenha um melhor desempenho quanto à ignição e perda de resistência mecânica devido à degradação térmica de seus componentes. O aumento de desempenho pode ser obtido pela modificação das propriedades térmicas madeira através de seu tratamento. Assim, utilizou-se o processo solvotermal assistido por micro-ondas para a modificação da… Show more

“…Therefore, the surface coverage of alumina did not confer any gain to neither physical nor mechanical characteristics of the treated pine wood. Previous studies reported similar mechanisms, for instance, Zanatta et al (2018), who treated a Brazilian pine wood with TiO 2 nanoparticles. They reported only changes related to surface features, such as color, moisture absorption, and flame retardancy.…”

“…Mathematical models prepared to predict the mass loss values based on the burning time can be consulted in the supplementary material. Zanatta et al (2018) affirmed that, when the outer layer of alumina particles is removed, those particles located inside the wood may act as a protective barrier, which reduces the flame spreading.…”

“…In a laboratory, different approaches are used, such as pressure, ultrasonic impregnation, solvothermal/ hydrothermal, microwave-assisted impregnation, dip-coating or a combination of several techniques. 18,[21][22][23][24] The reader is also referred to a comprehensive review on the sol-gel wood preservation. 25 Considering the numerous studies undertaken to produce universal formulation for wood protection, one can relate that there is still need for alternatives with fewer health and environmental concerns, whilst wood properties such as mechanical strength, re-retardancy, corrosion and photodegradation need to be preserved aer modication.…”
