Effect of the structural characteristics of anionic additive on the properties of coal water slurry;

We also take into account the content of crude protein in order to optimize the best manufactural techniques for new anion chemical additives.

According to the electric charge distributing the soil particle surface and the mechanism of swelling-shrinking of expansive soil,one kind of cationic additive was synthesized by the author.

The paper introduced the reaction mechanism of the cationic additives in the coating color for ink-jet printing paper, their development status at home and abroad and application prospects.

In this study, three kinds of poly dimethyl diallyl ammonium chloride (Poly-DMDAAC) synthesized in laboratory are applied as cationic additives in ink-jet printing paper coatings and the objectives are to evaluate the effects of cationic additives in coating formulations on high sheared apparent visco.

The synthetic product poly-DMDAAC was subsequently prepared based on free radical solutions polymerization, which was then applied as cationic additives in ink-jet paper coating.
