    The tanks (5 mm) spray water for 5 min at a rate of 20 ml / min.
    The obtained granules are dried to a residual moisture content of 10%.
    Thus, wet, non-sticky and instantly soluble granules having the following characteristics are obtained;
    Size, mm 0.5-1 mm
    Weight 0.35
    The degree of aeration,% 60
    In the absence of an additive, complete dissolution of the granules occurs only after 50 minutes.
    PRI mme R 2. 200 g of xanthan powder are mixed in a mixer with 9 g of sodium polymethylenemethylnaphthalene sulfonate and 1 g of sodium dioctylsulfosuccinate. The mixture of powders is placed in a granulator, moistened, granulated, and then dried in example 1. The characteristics of the soil (size, specific gravity, degree of aeration) are identical to those obtained in example 1.
    The granules of examples 1 and 2 are tested from the point of view of their dissolution rate: a solution is prepared in a beaker, filled in with weak stirring (magnetic rod) in one portion without any precautions 0.5 g of granules in 100 g of water containing 50 g / l NaCI and 5 g / l CaCl2 H2O20. Stirring is continued until a constant viscosity is obtained.
    Relative viscosity is measured using a Brookfield viscometer (speed 30 rpm, engine 2-20 ° C).
    Froze They operate with different granulometric compositions under conditions similar to that of lvlepy 1, but water is replaced by an aqueous solution containing various wetting and dispersing additives. The concentration of the solution is set to obtain the compositions shown in the table.
    The following wetting agents are used: sodium dioctyl sulfosuccinate, sodium dodecylbenzenesulfonate, polyoxyethylene containing nonylphenol 10, palm oil glycerides, OE-OR fatty alcohols.
    Dispersing agents: copolymer of malein-diisobutylene anhydride, having a mol. about 10,000 weight, sodium polymethylene naphthalene sulfonate.
    Wet dispersing agent: polyoxyethylene containing tri- (1-phenylethyl) phenolic phosphate containing 16 OE.
    Using the obtained granules, solutions up to 500 bph are prepared. xanthan in
    water containing 100 g / l NaCI + 10 g / l CaCl2X2H20.
    The compositions of the granules and the results obtained are tabulated (the water consumption in all 5 examples was 50% by weight of xanthan gum).
    Formula and 3 o barrels
    1. A water-soluble composition that has thickening properties, contains xanthan gum, a target additive and water, characterized in that, in order to increase the safety of use of the composition and ensure a high rate of its dissolution in water,

    0 sodium, polyoxyethylene nonylphenol, palm oil sugars glycerides, SdS-fatty alcohols containing polyoxyethylene and prlioxypropylene residues, diisobutylene copolymer with
    5 maleic anhydride (potassium salt), sodium polymethylene naphthalene sulfonate, oxye ™ len-tri) - (1-phenylethyl) phenol phosphate and oxyethylene alkylphenol phosphate in the following ratio of components, wt.%:
    0 xanthan gum 85.5-89, IN indicated target additive 0.9-4.5; water 10, the composition being in the form of granules with an average size of 0.5-1 mm.
    2. A method of obtaining a water-soluble 5 composition with thickening
    blending xanthan gum with a targeted additive, characterized in that, in order to increase the safety of the use of the composition and ensure
    0 high rate of dissolution in water; one or more compounds selected from the group comprising sodium polymethylene methyl naphthalene sulfonate are used as the target additive,
    5 dioctylsulfonate phenol phosphate and oxyethylene alkylphenol phosphate,
    5, the mixing is carried out at a xanthan gum: target ratio 95-99: 1-5 weight ratio by spraying water onto a fluidized bed of xanthan gum powder using water in a quantity of 50% by weight of xanthan gum.
    the target additive is then added to the xanthan gum powder or water, and the resulting granules are dried to a residual moisture content of 10%.
