METHOD BACTERIAL STABILIZATION OF GROUND WATER natural calcium carbonate and / or precipitated calcium carbonate and / or dolomite and / or mineral compositions containing surface-modified CALCIUM CARBONATE

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, glutarald
