Processes for preparing cellulose products, such as paper products which include substantially simultaneously or sequentially adding at least one aluminum compound and at least one silicate to a cellulose slurry, to a cellulose slurry such as a paper slurry. In, particular, the present invention is directed to processes for preparing the cellulose products, such as paper products which include substantially simultaneously or sequentially adding at least one aluminum compound and at least one monovalent silicate or water- soluble metal silicate complex to a cellulose slurry, such as a paper slurry. Compositions containing at least one aluminum compound and at least one water-soluble metal silicate, and cellulose products, such as paper products containing at least one water-soluble metal silicate complex.
Cette invention concerne un procédé de fabrication de produits cellulosiques, tels que des articles en papier, qui consiste à ajouter de façon sensiblement simultanée ou séquentielle au moins un composé d'aluminium et au moins un silicate à une suspension cellulosique épaisse, de papier par exemple. Plus précisément, La présente invention concerne des procédés de fabrication de produits cellulosiques, tels que des articles en papier, qui consistent à ajouter de façon sensiblement simultanée ou séquentielle au moins un composé d'aluminium et au moins un silicate monovalent ou un complexe de silicate de métal hydrosoluble à une suspension cellulosique épaisse, de papier par exemple. L'invention concerne également des compositions renfermant au moins un composé d'aluminium et au moins un silicate de métal hydrosoluble, et des produits cellulosiques tels que des articles en papier renfermant au moins un complexe de silicate de métal hydrosoluble.
