Abstract
The present invention relates to the use of a soluble magnesium compound for adjusting, in particular reducing, the viscosity of an aluminum sulfate suspension.
Claims19
A method for adjusting a viscosity of an aluminum sulfate suspension,
- the method comprising as alternative (1), the steps of:
- a) initially charging an aqueous preparation of aluminum sulfate and
- b) mixing in a soluble magnesium compound
- c) optionally mixing in further aluminum sulfate,
- to obtain an aluminum sulfate suspension,
- or
- the method comprising as alternative (2), the steps of:
- a) initially charging an aqueous preparation of a soluble magnesium compound and
- b) mixing in aluminum sulfate to obtain an aluminum sulfate suspension, and
- wherein, with regard to both alternatives (1) and (2), no organic acids are charged or mixed in.
7 more elements

- a) 22-46% by weight of aluminum sulfate (Al2(SO4)3;
- b) optionally 0.01-15% by weight of aluminum hydroxide (Al(OH)3);
- c) 0.035-10.4% by weight of magnesium oxide;
- d) optionally 0.001-5% by weight of calcium oxide;
- e) optionally 0.001-10% by weight of iron;
- f) optionally 0.001% to 5% by weight of silicon dioxide;
- g) optionally 0.001-20% by weight of at least one of an alkali metal aluminate and an alkaline earth metal aluminate;
- h) optionally 0.1-15% by weight of alkanolamine;
- i) optionally 0.01-10% by weight of fluoride;
- j) and a remainder being water,
- wherein the accelerator is free from organic acids.
