Аспекти виготовлення композиційного матеріалу при застосуванні червоного шламу

A composite material was developed with the polymeric binder at the elevated concentration of a technogenic raw material, 75 % by weight of red mud, as the filler. Dependence of indicators of composite properties on the content of the filler at the differentiation of varieties of polymer binders was established. When applying the binder Acronal 290 D, the water absorption minimum is 3.2–3.5 % by weight, the maximum is 5.0–5.3 % by weight. When applying Pliolite AC-4, the water absorption minimum is 0.83–0.96 % by weight, the maximum is 3.0–3.2 % by weight. When replacing the binder from the aqueous dispersion with the varnish dispersion, it is observed that water absorption level decreases by two times, but the character of dependence of this indicator on concentration of the filler remains unchanged. Analysis of hydrophobicity as a factor of improvement of operational properties of the composite showed that the maximum values of wetting angle of 130–136 degrees are registered at the concentration of the filler of 75 % by weight.We established features of the porous structure of the composite as a factor of influence on its properties. Total porosity and development of its varieties depend on the type of the polymeric binder. Indicators of total porosity are at the level of 9.3–11.8 % against 8.6–23.9 %, and the indicators of open porosity are at a significantly lower level of 0.96–3.15 versus 3.49–5.32 over the same range of changes in the concentrations of the filler when using Pliolite AC-4 compared to Acronal 290 D.It was shown that the developed material is distinguished by decorative (red color) and physical-technical characteristics that are important for modern architecture, which contributes to solving comprehensively the tasks on extending the range of composites and on the industrial waste disposal.Рассмотрена возможность увеличения объемов утилизации отходов производства глинозема – красного шлама путем использования в качестве наполнителя для изготовления полимерного композиционного материала.

Research and Science Today No. 2(6)/2013

RESEARCH AND SCIENCE TODAY is a biannual science journal established in 2011. The journal is an informational platform that publishes assessment articles and the results of various scientific research carried out by academics. We provide the authors with the opportunity to create and/or perfect their science writing skills. Thus, each issue of the journal (two per year and at least two supplements) will contain professional articles from any academic field, authored by domestic and international academics. The goal of this journal is to pass on relevant information to undergraduate, graduate, and post-graduate students as well as to fellow academics and researchers; the topics covered are unlimited, considering its multi-disciplinary profile. Regarding the national and international visibility of Research and Science Today, it is indexed in over 30 international databases (IDB) and is present in over 200 online libraries and catalogues; therefore, anybody can easily consult the articles featured in each issue by accessing the databases or simply the website
