WATER-SWELLING POLYMER-MINERAL COMPOSITE AND METHOD OF OBTAINING IT. |
摘要 |
<p>A water-swelling polymer-mineral composite comprises bentonite clay and a linear polyanionic polymer, with molecular mass of 10<6> or more, taken at quantities at which the mass ratio between said polymer and the bentonite clay is 0.05 to 0.10. Said composite is obtained by mixing, in the presence of water, the bentonite clay and the linear polyanionic polymer, with a molecular mass of 10<6> or more, taken at quantities to give a mass ratio between the said polymer and the bentonite clay of 0.05 to 0.10. The resulting mixture is then dried until the solid desired product is obtained.</p> |
