Abstract
A polynucleate aluminum hydroxy silicate-sulphate compound (PASS) having the following average composition:
Al A(OH)B(SO4)C(SiOX)D(H2O)E
wherein A is 1.0;
B ranges from 0.75 to 2.0;
C ranges from 0.30 to 1.12;
D ranges from 0.005 to 0.1;
X is greater than 2.0 but less than or equal to 4.0 such that 3 = B + 2C + 2D (X-2);
E is larger than 4 when the product is in aqueous form. The compound is useful for water treatment and other applications where an aluminum hydroxide gel system is required, but the compound is especially useful as a drainage and retention aid and size promoter for use in papermaking. The compound, in aqueous solution, has a long storage life.
