摘要:
1. A method of stabilizing an aqueous mineral composition, comprising the step of: (a) adding at least one aldehyde-containing and / or aldehyde-releasing and / or phenolic and / or izotiazolinovogo biocide to said aqueous mineral composition, characterized in that: - said mineral comprises at least one component from the following: ground natural calcium carbonate, precipitated calcium carbonate, dolomite, surface-modified calcium carbonate, or a mixture thereof, - said method includes the step (b), which can be simultaneous and / or separate with respect to step (a), adding at least one primary alkanolamine with residual monohydric alcohol to said aqueous mineral composition - said biocide (s) is added to the aqueous composition in an amount corresponding to the interval from 90 to 1350 h / million based on the weight of the aqueous phase of said aqueous composition and- said primary alkanolamine (s) with residual monohydric alcohol is added to said aqueous composition in an amount corresponding to the interval from 600 to 1200 parts / million by weight of the aqueous phase of said aqueous kompozitsii.2. A method according to claim 1, characterized in that said aldehyde-containing and / or aldehyde-releasing and / or phenolic and / or izotiazolinovy ​​biocide (s) is added to the aqueous composition in a total amount of 100 parts / million to 1000 parts / million and preferably in an amount of 150 parts / million to 800 parts / million, calculated relative to the water in kompozitsii.3. A method according to claim 1 or 2, characterized in that the said biocide on the basis of the aldehyde is selected from the group consisting of formaldehyde, acetaldehyde, glyoxal, suktsinaldegida, glutarald1. Способ стабилизации водной минеральной композиции, включающий стадию:(а) добавления по меньшей мере одного альдегид-содержащего и/или альдегид-высвобождающего и/или фенольного и/или изотиазолинового биоцида к указанной водной минеральной композицииотличающийся тем, что:- указ
