More Information
Summary:MMVF fibers having a low alumina content are formed from a melt made in a furnace by melting a mineral charge which comprises novel mineral briquettes made by compression molding a particulate mineral material having an alumina content below 4 % and a binder that is substantially free of aluminium and that comprises lignin. The briquettes preferably contain vegetable or other fibres to improve green strength. On forme des fibres vitreuses synthétiques (MMVF) possédant une faible teneur en oxyde d'aluminium à partir d'un bain de fusion réalisé dans un four et consistant à faire fondre une charge minérale comprenant de nouvelles briquettes minérales de ferro-alliage produites par moulage par compression d'un matériau minéral particulaire possédant une teneur en oxyde d'aluminium inférieure à 4 % ainsi qu'un liant sensiblement dépourvu d'aluminium et comprenant de la lignine. Ces briquettes contiennent de préférence des fibres végétales ou autres afin d'améliorer la résistance à l'état vert.
