摘要： The present invention relates to the technical field of building additives, and in particular to a preparation method of modified starch ether for improving the open time of a ceramic tile adhesive. The method includes (1) chemical modification: mixing starch, alkalizer, alcohol and inhibitor, then adding a plurality of etherifying agents, and conducting etherification at 10°C to 90°C for 2 h to 20 h to achieve the chemical modification and obtain starch ether; and (2) physical modification: mixing the starch ether obtained in step (1), thickener, retarder and water reducer for a certain period of time to achieve the physical modification. The modified starch ether prepared by the preparation method is used in a ceramic tile adhesive to significantly improve the binding performance and the open time of the ceramic tile adhesive, which cannot be achieved by the existing starch ether products and methods.

摘要： The invention is designed for the efficient cross-linked cationic starch flocculant of the broad flocculation window, which during the flocculation of suspensions is able to bind soluble anionic pollutants, and for method of production of such flocculant. Cross-linked cationic starch is obtainable by cross-linking and cationization of starch in one-stage or two-stage process. The flocculant is obtained by dispergation of microgranules of cross-linked cationic starch with use of shear forces in water or aqueous mixture with multifunctional alcohols after swelling of modified starch in the dispersion medium up to the balance state. A degree of substitution of the discrete submicro-, nanoparticles of the modified starch flocculant according to cationic groups is from 0.15 to 0.28, accessibility of its cationic groups for polyanions is between 15 and 40 percent.
