| 摘要 | The present invention is directed to a colloidal aqueous silicate dispersion containing silica and alumina, the molar ratio between silica and alumina being 2 - 12, as well as to a method for its preparation. Said method is characterized by dissolving a particulate mineral material, such as a mineral wool or fibre product containing silica and alumina in a molar ratio of 2 - 12 in an aqueous solution, nucleating and stabilizing the so obtained solution, and optionally adjusting the dry matter content of the dispersion so obtained. The said dispersion can also be made to gel. The invention is also directed to the use of the dispersion as a binder. | ||||||
