MENDES, Rafael Farinassi et al. The adhesive effect on the properties of particleboards made from sugar cane bagasse generated in the distiller. Rev. de Ciências Agrárias [online]. 2009, vol.32, n.2, pp.209-218. ISSN 0871-018X.
The objective was to evaluate the effect of the adhesive type and its different contents on sugar cane bagasse particleboards. The panels were produced using Urea-Formaldehyde (UF) and Phenol-Formaldehyde (PF) adhesives. Three adhesive contents were tested: 6, 9 and 12%. The boards were made by using an 8-minute press closing time, pressure of 40kgf/cm², and temperature of 160ºC for the UF adhesive and 180ºC for the PF adhesive. It was concluded that: The UF adhesive was statistically equal or better than PF adhesive considering all properties evaluated. The adhesive contents of 9 and 12% were statistically equal, but both were superior to 6% considering the physical properties. The mechanical properties did not present statistical differences, except for rupture modulus. The best panels were produced using UF at 9%, but they did not attend the norm CS 236-66 for mechanical properties, therefore it is necessary manipulations of the processing variables.
