Effects of weathering on the roughness of Pinus sp. particleboards
2018Co-Authors: Maria Fátima Do Nascimento, Andre Luis Christoforo, Cristiane Inácio De Campos, Diego Henrique De Almeida, Francisco Antonio Rocco LahrAbstract:Abstract The aim of this research was to evaluate the influence of the period of exposure (0, 1, 2, 3 and 4 months), the type of preservative agent (CCA and CCB) and the surface coating type (castor oil based Polyurethane Resin; water-based open pore coating with sunscreen) in the roughness values (Ra) of particleboards manufactured with wood Pinus sp.and castor oil based Polyurethane Resin, as well as to investigate the possibility of roughness estimation as a function of the measurements of colorimetric parameters (L*, a* and b*). The results of the roughness values (between 0.07 µm and 2.82 µm) were lower than 12.5 µm, which categorizes the panels produced in the N10 class of ABNT NBR 8404 (1984) standard, thus showing the potentiality of the composites manufactured. The use of the castor oil based Polyurethane Resin coating gave the lowest values of roughness and the roughness values of the aged panels during the four months were statistically equivalent, evidencing the good performance of the fabricated materials. The good quality obtained from the multivariable regression models (R2 = 77.02%) show the possibility of estimating the roughness by colorimetric parameters.

Results related to modulus of rupture (MOR) and modulus of elasticity were determined. Four proportions polyol/pre-polymer were evaluated: 0.75:1; 1:1; 1:1.25; 1:1.5. Results showed improvement in MOR and MOE with increase of pre-polymer component. Proportion 1:1.25 (poliol: pre-polymer) was considered the most interesting once employs the least amount of the petroleum-derived component.

medium density fiberboard manufactured with castor oil based Polyurethane Resin
Revista Vértices, 2013Co-Authors: Sergio Augusto Mello Da Silva, Andre Luis Christoforo, Tulio Hallak Panzera, Francisco Antonio Rocco LahrAbstract:Este trabalho objetivou avaliar a viabilidade da producao de paineis MDF fabricados com madeiras das especies Pinus caribaea e Eucalyptus grandis e Resinas poliuretanas mono e bicomponente derivadas do oleo de mamona, com base nas recomendacoes da norma europeia Euro MDF Board (EMB/ IS-2:1995). Os paineis desenvolvidos com ambas as Resinas foram confeccionados com parâmetros de fabricacao distintos, em razao de testes preliminares desenvolvidos. Com excecao da absorcao de agua apos 24 horas dos materiais fabricados com a madeira Eucalyptus grandis, todas as demais variaveis resposta atenderam aos requisitos do documento normativo europeu, evidenciando a potencialidade dos materiais fabricados. Entretanto, pelos valores significativamente superiores obtidos das propriedades mecânicas aliados aos excessivos valores da absorcao de agua, de maneira a contribuir com a possivel fabricacao dos paineis em escala industrial, novas pesquisas devem ser desenvolvidas, com o objetivo de testar novos valores para os parâmetros de fabricacao, que possibilitem a reducao dos teores das Resinas utilizados.
