Abstract

a presente invenção se refere a um método para a acetilação contínua de elementos de madeira. a acetilação é conduzida com um meio de acetilação em uma pressão de pelo menos 0,15 mpa (1,5 barg) em um ambiente substancialmente livre de oxigênio. alternativamente, o método de acordo com a invenção compreende as etapas de: (a) alimentar elementos de madeira em um ambiente substancialmente livre de oxigênio para um reator de acetilação contínua, e (b) tratar os elementos de madeira com um meio de acetilação no reator de acetilação contínua sob condições de reação de acetilação de madeira, em uma pressão de pelo menos 0,15 mpa (1,5 barg). o processo de acordo com a presente invenção permite a acetilação de elementos de madeira até um alto teor de acetil de um modo muito eficiente, sem comprometer a qualidade do material. os elementos de madeira acetilados podem ser usados na produção de placas de fibra de densidade média com qualidades superiores tais como estabilidade dimensional e durabilidade.
