Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

e effect of the concentration and charge of the water-soluble polyelectrolytes on the kinetics of aggregation of kaolin particles was studied.It has been shown that the rate of stirring affects formation, size and strength of flocs.e rate of aggregation and the size of the mineral particle forming floccules increase with the increase of reagent concentration and the charge density of the polyelectrolyte.At low concentrations (2.75-3.8mg/g) of individual polyelectrolytes (FO 4800 SSH, FO 4650 SSH) and content of binary mixtures of polyelectrolytes in the ratio of 1: 9 by mass (0.77 mg/g), the flocculation of mineral suspension increases.Mineral suspension is stabilized at the increase of concentration (>5.5 mg/g).
