      <abstract xml:lang="ru">
        <p>Выполнен комплексный анализ эффективности использования натрий-карбоксиметилцеллюлозы (Na-КМЦ) в производстве влагопрочной бумаги. Na-КМЦ – это водорастворимая анионная модификация целлюлозы, получаемая этерификацией целлюлозы хлорацетатом натрия в щелочном растворе. Образующийся полимер отличается высоким уровнем гидрофильности благодаря наличию карбоксильных (-COO⁻) и гидроксильных (-OH⁻) групп, что обеспечивает высокую растворимость этого соединения в воде и формирование стабильных коллоидных растворов. Исследовано влияние Na-КМЦ на процесс подготовки бумажной массы и эксплуатационные свойства конечной продукции. Показано, что применение Na-КМЦ оказывает комплексное положительное воздействие на физико-механические, оптические и барьерные свойства бумаги. Na-КМЦ вступает в реакцию с такими компонентами бумажной массы, как древесные и синтетические волокна, наполнители и клеящие вещества, и за счет этого усиливает адгезивные свойства и улучшает общую структуру бумаги. Na-КМЦ проявляет комбинированный эффект в многокомпонентных системах, повышая активность и эффективность других химических веществ – влагопрочных смол и пигментов. В ходе работы установлены количественные соотношения, объясняющие зависимость качества бумаги от расхода Na-КМЦ. Область применения результатов охватывает производство белых видов бумаг с высокими эксплуатационными характеристиками, особенно в условиях требований снижения экологической нагрузки на стоки. Методика может быть адаптирована под действующие производственные линии целлюлозно-бумажных предприятий.</p>

        <p>The paper presents a comprehensive analysis of the effectiveness of sodium carboxymethylcellulose (Na-CMC) in the production of wet-strength paper. Na-CMC is a water-soluble anionic cellulose derivative produced by the esterification of cellulose with sodium chloroacetate in an alkaline solution. The resulting polymer is highly hydrophilic due to the presence of carboxyl (-COO⁻) and hydroxyl (-OH⁻) functional groups, which ensures the compound's high solubility in water and the formation of stable colloidal solutions. This study investigated the effect of Na-CMC on the paper pulp preparation process and the performance properties of the final product. The use of NA-CMC has been shown to have a comprehensive positive effect on the physical and mechanical, optical, and barrier properties of paper. NA-CMC reacts with paper pulp components such as wood and synthetic fibers, fillers, and binders, thereby enhancing the paper's adhesive properties and improving its overall structure. Na-CMC is effective in multi-component systems; it enhances the activity and performance of other chemical substances, such as moisture-resistant resins and pigments. The study revealed quantitative relationships that explain how paper quality depends on the amount of NA-CMC consumed. The results are applicable to the production of high-performance white papers, particularly in terms of reducing the environmental impact of wastewater discharges. The method can be adapted to existing production lines at pulp and paper mills.</p>
