Abstract

L'invention concerne un procédé de fabrication permettant de limiter considérablement le dégagement de formol labile des éléments de particules lignocellulosiques encollés avec une résine à base de formol. Le procédé permet également de laisser refroidir lentement les éléments en sortie de presse sans dégradation de leurs propriétés mécaniques. Le procédé consiste à associer aux constituants de base des éléments un dérivé de métal alcalino-terreux, et de préférence un sel de baryum ou de calcium.
