Kostyrya M. The polyurethane thickening modification on the basis of building shear stream model

The investigation object - polyurethane thickenings of the pigment printed composition. The investigation subject - the polyurethane thickenings modifying on the basis of building shear stream model. The tasks putting in the work are solved with use of the theoretical and experimental investigation methods by means of the mathematical implement and the information technologies. A rheological mathematical model of polyurethane thickenings was first constructed. The model takes into account the shear thickening effect and enables: to carry out thickenings modification and to receive thickenings with necessary rheological properties, to offer more ecological system of solvents for thickening. The offered theoretically reasonable modification ways enable: to receive thickenings with necessary rheological behaviors on the printed equipment, to expand the thickening's assortment for the textile industry, to increase quality of the textile production. The introduction on the finishing manufactures of the tex tile industry is planned.
