This is necessary in order to ensure the adhesion of the gypsum core to the cardboard and, as a result, to give the sheets the required mechanical and physical properties. The use of various kinds of modified starches in the production technology of PBS makes it possible to achieve the required adhesion with fluctuations in the phase composition of the binder and deviations in the drying mode of products. Considering this, it becomes obvious that the characteristics of modified starches have a significant effect on the quality of PBS. The study of existing standards regulating the quality indicators of starch derivatives showed the absence of parameters reflecting the effectiveness of their use in the production technology of PBS. In this paper, the structural features of the most widely used types of modified starch are considered. The paper summarizes information about the mechanism of adhesion of the gypsum core to cardboard, the factors influencing this process, the mechanisms of starch destruction and oxidation, and also offers a list of quality indicators of starch derivatives and the requirements for them. It is shown that the effectiveness of the use of modified starches in the production of PBS is achieved by regulating the direction and depth of the processes of destruction and oxidation.</p></abstract><trans-abstract xml:lang="ru"><p>Технологический процесс производства ГКЛ требует тщательного контроля фазового состава используемого гипсового вяжущего, а также соблюдения режимов сушки листов. Это необходимо с целью обеспечения сцепления гипсового сердечника с картоном и, как следствие, придания листам требуемых механических и физических свойств. Использование в технологии производства ГКЛ различного рода модифицированных крахмалов позволяет достичь требуемого сцепления при колебаниях фазового состава вяжущего и отклонениях в режиме сушки изделий. С учетом этого становится очевидным значимое влияние характеристик модифицированных крахмалов на качество ГКЛ. Изучение существующих стандартов, регламентирующих показатели качества производных крахмала, показало отсутствие параметров, отражающих эффективность их применения в технологии производства ГКЛ. В представленной работе рассмотрены структурные особенности наиболее широко используемых типов модифицированного крахмала. В работе обобщены сведения о механизме сцепления гипсового сердечника с картоном, факторах, влияющих на данный процесс, механизмах деструкции и окисления крахмала, а также предложен перечень показателей качества производных крахмала и требования, предъявляемые к ним. Показано, что эффективность применения модифицированных крахмалов при производстве ГКЛ достигается путем регулирования направленности и глубины протекания процессов деструкции и окисления.</p></trans-abstract><kwd-group xml:lang="en"><kwd>modified starch</kwd><kwd>PBS</kwd><kwd>destruction</kwd><kwd>oxidation</kwd><kwd>calcium sulfate semi-hydrate</kwd><kwd>gypsum binder</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>модифицированный крахмал</kwd><kwd>ГКЛ</kwd><kwd>деструкция</kwd><kwd>окисление</kwd><kwd>полугидрат сульфата кальция</kwd><kwd>гипсовое вяжущее</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jiang T., Duan Q., Zhu J. et al.
