MINERAL FIBRES CAPABLE OF DISSOLVING IN A PHYSIOLOGICAL MEDIUM. |
摘要 |
<p>The present invention relates to mineral fibre composition which can dissolve in contact with a physiological medium. The composition of these fibres includes the following components, in accordance with the following proportions by weight: - SiO2 48 to 67% - Al2O3 0 to 8% - Fe2O3 0 to 12% - (total iron expressed in this form) - CaO 16 to 35% - MgO 1 to 16% - Na2O + K2O 0 to 6.5% - P2O5 0 to 5% - taking into consideration that these compositions are also defined by the fact that the contents of these components comply with the following ratios: Na2O+P2O5>/=2%Fe2O3+Al2O3</=12%CaO+MgO+Fe2O3>/=23%.</p> |
