A method of making a finished product such as a building board includes the steps of forming a mixture of an expanded mineral such as exfoliated vermiculite and a thermosetting resin, pressing the mixture at a temperature in the range of from 100 to 220 ~C inclusive to form a green product with a density in the range of from 200 to 650 kg/m3 inclusive, firing the green product in a kiln to its transition temperature to burn off substantially all of the organic constituents of the green product and thereby establish inorganic induced coherence to form the finished product, and allowing the finished product to cool.
L'invention concerne un procédé de fabrication d'un produit fini, tel qu'un panneau de construction, consistant à former un mélange d'un minéral expansé, tel que de la vermiculite exfoliée, et d'une résine thermodurcissable, à presser le mélange à une température comprise entre 100 et 220 ·C compris en vue de former un produit vert dont la densité se situe entre 200 et 650 kg/m?3¿ compris, à chauffer ledit produit vert dans un four jusqu'à sa température de transition afin de calciner la quasi-totalité des constituants organiques du produit vert, ce qui permet d'établir une cohérence inorganique induite pour former le produit fini, et enfin à laisser refroidir le produit fini.
