Thermal Performance of Aviary Prototypes Fitted With Osb Panel Ceiling Made of Balsa Wood Wastes

Abstract

This study describes the potential of using an OSB panel ceiling, made of Balsa wood wastes agglomerated with a polyurethane resin based on castor oil, in prototypes of aviaries covered with fiber cement tiles. For the study, the internal temperature, relative humidity and the thermal comfort indexes, such as the environmental thermal index of productivity for broilers (IAPfc) and enthalpy, were measured and a Fuzzy logic classification system was used. The data were collected during the spring and summer, for 15 days. The results indicate that the presence of ceiling provided a reduction in the radiation transfer to the interior of the aviary prototypes, reflecting on the reduction of the ambient temperature and the thermal comfort indexes measured during spring and summer. Based on the Fuzzy classification system and on the data obtained, it can be concluded that there is a small difference between the aviaries with and without a ceiling.

Environmental evaluation of experimental heat-treated oriented strand board

“…According to Ferro et al (2018), since changes in the resin type could decrease the technical properties of the panels, it is firstly mandatory to assess the effects of the bioresins on the physic-mechanical properties of the manufactured boards. However, the technical performance of H_OSB has already been successfully evaluated in the work of Sugahara et al (2022b) and the potential of use of the polyurethane adhesive derived from castor oil in wood panels has already been established in several other studies (Barbirato et al 2019b(Barbirato et al , 2020Sugahara et al 2019Sugahara et al , 2022a.…”

Study of the Influence of Heat Treatment on OSB Panels Produced with Eucalyptus Wood in Different Layer Compositions

“…The castor oil polyurethane adhesive is a formaldehyde-free resin [22] from renewable origins, derived from the Ricinus Communis L. plant, which is abundant in Brazil. Moreover, due to the fact that it is highly water resistant compared to Urea-formaldehyde (UF) [25], it has shown good performance for adhesion of wood particles on panels [22,24,25,29,31,32].…”

Sandwich panel of oriented particles with unconventional and waste materials

“…Balsa has been used by companies in the nautical and aeronautical sectors for its light weight and high mechanical properties for low-density wood. Recent studies (BARBIRATO et al, 2019a(BARBIRATO et al, , 2018(BARBIRATO et al, , 2019bCABRAL et al, 2018) have investigated this type of wood for the production of OSB panels.…”
