Resumo: | The objective of this work was to produce and characterize particleboards manufactured with pine wood and pistachio shell. Three mix proportions of 25, 50 and 75% were used, and for the control, panels manufactured with 100% pistachio shell were adopted. The panels were produced with a nominal density of 0.75 g cm-3. The properties analyzed were: apparent density, water absorption, thickness swelling, modulus of rupture, modulus of elasticity and perpendicular traction. The chemical characterization of the particles showed that the extractives content of pistachio was higher than the content obtained for pine wood. There was no significant difference for physical properties and all values obtained for IE 24 h, of panels composed of a mixture of particles (T1, T2 and T3) were contemplated by the Brazilian standard. Significant differences were found for mechanical properties, as well as a decrease in strength. The MOR of the panels made up of 25% pistachio and 75% pine wood showed a satisfactory value, as the standard requires a minimum value of 11.00 MPa and the panels reached an average value of 11.38 MPa. For perpendicular traction, the T1 and T2 treatment panels met the standard requirement, reaching values above 0.35 Mpa. |

Foram utilizadas três proporções de mistura de 25, 50 e 75%, e para o controle adotou-se painéis constituídos com 100% de casca de pistache. Os painéis foram produzidos com densidade nominal de 0,75 g cm-3. As propriedades analisadas foram: densidade aparente, absorção de água, inchamento em espessura, módulo de ruptura, módulo de elasticidade e tração perpendicular. A caracterização química das partículas evidenciou que o teor de extrativos do pistache foi superior ao teor obtido para a madeira de pinus. Não houve diferença significativa para as propriedades físicas e todos os valores obtidos para IE 24 h, de painéis compostos por mistura de partículas (T1, T2 e T3) foram contemplados pela norma brasileira. Constataramse diferenças significativas para as propriedades mecânicas, bem como um decréscimo na resistência. O MOR dos painéis constituídos com 25% de pistache e 75% de madeira de pinus evidenciaram valor satisfatório, pois a norma exige um valor mínimo de 11.00 MPa e os painéis atingiram valor médio de 11.38 MPa. Para tração perpendicular os painéis dos tratamentos T1 e T2 atenderam a exigência da norma, atingindo valores superiores a 0.35 MPa.Universidade Federal Rural de Pernambuco (UFRPE)2022-02-11T15:57:23Z2022-02-11T15:57:23Z2021-05-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfBRITO, F.
