Modeling of the water-conservating screen of hydrogel in soil solutions of various mineralization
Water-swelling polymer hydrogels are among the promising meliorative means that expand the possibilities of controlling the water regime of soils. Hydrogels repeatedly increase their volume as a result of swelling, have a high water-absorbing capacity, but do not dissolve. In the article are considered the possibilities of application of moisture-swelling polymers RYTIN-10 - sodium base and B-415K - potassium base, as water-retaining screens in soil solutions of different mineralization. It was established that the kind of moistening (gravitational or capillary saturation) does not affect the swelling ratio of Ritin-10 and B-415K. The multiplicity of the swelling of B-415K is much greater than the swelling ratio of Ritin-10 and has undoubted priority in use for soil loads (depth of deposition) to 36 g/cm<sup>2</sup>.
