  • Patent number: 7300974
    Abstract: The invention relates to the selection of a natural calcium carbonate crushed to a high degree of fineness, possibly treated with one or more fatty acids or one or more of their salts or mixtures thereof, and its use as a rheology regulator for polymeric compositions. The specific surface area is 14 to 30 m2/g measured according to the BET method to ISO 4652, and the oil absorption is greater than 16 measured according to ISO 787-V (Rub-out method). The conditions of mixing of the constituents and manufacture are improved, as well as the properties of the final product.

  • Publication number: 20040020410
    Abstract: 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.

  • Patent number: 6627413
    Abstract: The present invention discloses a process for quantitative and/or qualitative determination of the microbial contamination of suspensions, emulsions or dispersions containing minerals and/or pigments and/or fillers and/or fiber materials wherein following the addition of one or more substances which can be degraded by microorganisms, mixing and optionally subsequent incubation a sample of the suspensions, emulsions or dispersions is centrifuged to separate the microorganisms from the minerals and/or fillers and/or pigments and/or fiber materials and the number and/or size and/or type of the microorganisms is determined in the aqueous supernatant phase after one or more incubations.
