Description

Uenb is comprehended by the fact that mlteriadly adheres to the chalk melt singing at a slower ratio of alum, weight,%: Polyester foam 40-94,4. Gypsophilus spo4,3-28,0 Mepovalny spo1,3-32, О. The proposed multi-point material as a malevalnogo layer may contain water - and organic polymers, copolymers, opigomers, and fill. - inorganic pigments with a particle size of 0.1-30 microns. Condensation resins capable of polycondensation under production conditions or when operating the material may also be included in the facial mepal layer. In the proposed multilayer material, polyester base allows to obtain high physicomechanical, and coating layer has good printing properties. However, the melamine compositions do not have sufficient adhesion strength to the polyester base, which, in the process of exploitation, leads to spalling of the coating (with typographical text on it). The use as a base of a multi-layer material, having a coating consisting of a hydrophysicucleus and non-hydrophilizing components, provides high adhesion of the coating layer. The highest adhesion is achieved when the hydrophilization of the hydrophilizing component K-0-Ct + H5.0- 2 K-OH + CH3C is taken under the conditions of applying the coating layer. The resulting hydroxyl groups interact with the functional groups of the coating layer components and provide a high adhesion of the coating layer. The emergence of strong adhesive-cohesive bonds can, in this case, be caused by the formation of chemical bonds of the polycondensable resin, which is part of the chalky composition. The kinetics of the hydrophilic process of the 5% hydrophilizing component of the coating is achieved by changing the pH of the coating composition. The formation of C1 hydrophilic groups provides good adhesion due to the formation of hydrogen bonds and in the case of the use of patex coatings. 1 l of tuluchoni of two working surfaces, hydrophilic and coating, are applied on the sides of the base.

Smoothness is almost as good as the well-known material. Such a high smoothness index permits the use of the proposed material for printing both text and illustrations with raster or large-lined raster images, as well as for high linnatures. raster illustrations and especially for four-color reproduction. The good absorbency of the material proposed (approximately 3-4 times more than that of a known material) makes it possible to use traditional inks when printing and not to change the temperature regime of printing. The proposed material, due to its high physicomechanical properties and moisture resistance, can be used for high-speed types of furnaces. Making the multilayer material based on polyester film adjustable (by choosing the type of melap coating) printing properties allows typographical methods (offset, gravure printing, etc.) to obtain high-quality marine, topographic, geographical and other maps that have moisture resistance when processed for 24 h fresh and sea water, dimensional stability and resistance to aging. . It will be of particular use in aviation, astronautics, navy, geodesy, cartography and surveying when reproducing high-precision documentation for special purposes. Economic efficiency is achieved by increasing the lifetime of the prints from 2-3 to 1O years.
