摘要

摘要:本研究介绍了巴尔沙木材废料的高级表征，以评估其作为定向刨花板(OSB)面板原材料的潜在用途。为此，对巴尔沙木颗粒进行了化学、热学和微观结构表征，然后生产和表征了蓖麻油聚氨酯树脂(Pu-Castor oil)凝聚的OSB。结果表明，巴尔沙木材废料的木质素含量低于用于OSB板工业生产的松木木材的木质素含量，表明需要更高的树脂含量来确保颗粒的完美团聚。显微结构分析表明，巴尔沙木具有作为蓖麻籽油OSB组成原料的特点。物理力学表征表明，根据EN 300:2006指南，该材料可归类为OSB 1型，适合在内部环境中应用。

Evaluation of Balsa wood (Ochroma pyramidale) waste and OSB panels with castor oil polyurethane resin

ABSTRACT This research presents an advanced characterization of Balsa wood waste to evaluate its potential use as raw material for Oriented Strand Board (OSB) panel. For that, chemical, thermal and microstructural characterization of the Balsa wood particles were performed followed by the production and characterization of OSB agglomerated with castor oil polyurethane resin (Pu-Castor oil). The results indicated that the lignin content of the Balsa wood waste was lower than the content found in Pinus spp. wood, used in the industrial production of OSB panels, demonstrating the need for higher resin contents to ensure a perfect agglomeration of the particles. Microstructural analysis indicated that the Balsa wood presented characteristics to be used as a constituent raw material of OSB with Pu-Castor oil. The physical-mechanical characterization indicated that the material can be classified as OSB type 1 in accordance with the EN 300:2006 guidelines and is suitable for application in internal environments.
