Abstract
1. Способ получения поглощающих кислород элементов защитного покрытия, заключающийся в том, что на ядра из карбоната кальция наносят полимерную оболочку путем послойной адсорбции противоположно заряженных полиэлектролитов, в качестве которых используют полистиролсульфонат натрия и полидиаллилдиметиламмоний хлорид, удаляют ядра из полученных микрокапсул путем их растворения, помещают микрокапсулы в водный раствор флуоресцентного красителя трис-2,2-бипиридил дихлорида рутения при рН 9-10 и выдерживают до приобретения микрокапсулами ярко-оранжевой окраски, соответствующей окраске раствора. ! 2. Способ по п.1, отличающийся тем, что в качестве ядер из карбоната кальция используют монодисперсные сферические коллоидные частицы карбоната кальция. ! 3. Способ по п.1, отличающийся тем, что растворение ядер из карбоната кальция осуществляют путем выдержки микрокапсул в водном растворе двунатриевой соли этилендиаминтетрауксусной кислоты. 1. The method of producing oxygen-absorbing protective coating elements, which consists in applying a polymer shell to the calcium carbonate cores by layer-by-layer adsorption of oppositely charged polyelectrolytes, using sodium polystyrenesulfonate and polydiallyldimethylammonium chloride, removing the cores from the obtained microcapsules by dissolving them, and placing microcapsules in an aqueous solution of fluorescent dye tris-2,2-bipyridyl dichloride ruthenium at pH 9-10 and incubated until acquisition by microcapsules on-orange color corresponding to the color of the solution. ! 2. The method according to claim 1, characterized in that monodispersed spherical colloidal particles of calcium carbonate are used as nuclei from calcium carbonate. ! 3. The method according to claim 1, characterized in that the dissolution of the nuclei from calcium carbonate is carried out by holding the microcapsules in an aqueous solution of disodium salt of ethylenediaminetetraacetic acid.
