Novel treated filler or pigment or mineral for paper, in particular pigment containing natural caco3, method for making same, compositions containing them and uses |
摘要 |
The invention concerns a pigment, filler or mineral containing a natural calcium carbonate, treated with one of more providers of H3O+ ions and gaseous CO2, allowing a reduction in the weight of paper for a constant surface area without loss of physical properties when it is used as a pigment or coating filler for the said paper. In particular, the invention concerns a pigment, filler or mineral containing a natural calcium carbonate or dolomite or mixtures of talc and calcium carbonate, of kaolin and carbonate or carbonate alone or in combination with natural and/or synthetic fibres or similar, treated with one or more medium-strong or strong providers of H3O+ ions in the presence of gaseous CO2. Applications are particularly in the paper industry, obtaining in particular good sheet properties i.e. a reduction its weight for a given surface area. |
