Definitions
- This invention relates to a composition for treating inorganic slurries and to a method of treating inorganic slurries with the aforesaid composition so as to maintain the slurries in a substantially homogeneous phase.
- inorganic slurries contain about 70% to 80% by weight of solids.
- Many inorganic slurries are known to be susceptible to bacterial contamination and it has been the practice to add one or more biocidally-active materials to the slurries in order to minimise such contamination.
- Phosphorus-containing compounds in particular tetrakis(hydroxyorgano)phosphonium salts (THP + salts) are known to be effective biocides.
- THP + salts tetrakis(hydroxyorgano)phosphonium salts
- Experimental work carried out by the applicants has shown, for example, that the addition of a solution of tetrakis(hydroxymethyl)phosphonium sulphate (THPS) to a calcium carbonate-based slurry can give rise to a reduction in bacterial count of 10 4 in 2 hours.
- THPS tetrakis(hydroxymethyl)phosphonium sulphate
- composition comprising a THP + salt and a dispersant will provide continuing preservation against bacterial contamination, while at the same time maintaining the slurry in a substantially homogeneous phase.
- the present invention provides a composition for treating an inorganic slurry, the composition comprising:
- the THP + salt is preferably tetrakis(hydroxymethyl)phosphonium sulphate.
- the THP + salt may be tetrakis(hydroxymethyl)phosphonium chloride, phosphate, nitrate or oxalate.
- a preferred example of a dispersant of the type (b)(i) is a compound having one tertiary nitrogen atom, such as a sodium salt of nitrilo-tris(methylene phosphate), particularly the tetra-sodium salt.
- Preferred examples of dispersants of the type (b) (ii) include those oligomers having the general H(CH 2 OM.CH 2 OM).PO 3 M 3 , wherein M is a cationic species such that the oligomer is soluble in water and n is a number greater than 1.
- a preferred example of a dispersant of the type (b)(iii) is a homopolymer of acrylic acid, especially a homopolymer having a molecular weight in the range 2000 to 5000.
- Preferred examples of dispersants of the type b(iv) include sodium tripolyphosphate.
- the present invention provides a method of treating an inorganic slurry to maintain the slurry in a substantially homogeneous phase, the method comprising the addition to the slurry of an effective amount of a composition according to the first aspect of the present invention.
- the inorganic slurry may, for example, comprise a calcium carbonate-based slurry.
- the inorganic slurry may comprise a pigment slurry, a clay slurry or a cement slurry.
- the ratio of THP + salt to dispersant in the composition is about 2:1 (as active ingredients).
- the composition may be added to the slurry in an amount in the range 10 ppm to 1000 ppm (by weight of the slurry), for example about 750 ppm (by weight of the slurry).
