Abstract
(EN) FIELD: chemistry. SUBSTANCE: invention relates to the technology of producing chemical substances used in rebreathers on chemically bound oxygen, and can be used in production of products for regeneration of air based on potassium superoxide. Regenerative product for rebreathers includes potassium superoxide and magnesium silicate, obtained from chrysotile asbestos, with ratio of components in the composition of the regenerative product, wt%: chamber potassium superoxide KO2 90–95; magnesium silicate MgSiO3 5–10. Method of producing a regenerative product for rebreathers involves mixing potassium superoxide with magnesium silicate, followed by molding a mixture, wherein magnesium silicate is obtained from chrysotile asbestos by exposure to temperature of 800±20 °C for 2-3 hours with subsequent grinding in a drum mill. After molding, the regenerative product can be thermally stabilized according to: heating to 200±20 °C at rate of 1–5 °C/min; exposure at 200±20 °C for 1–2 hours. Regenerative product of the presented composition provides, during operation in the composition of the rebreather, a low average and maximum volume fraction of carbon dioxide on inhalation, a low temperature of the regenerated air on inhalation and a longer time of protective action. EFFECT: this provides more comfortable conditions for the user and allows to significantly expand the range of persons who can use these rebreathers. 3 cl, 1 dwg, 2 tbl, 3 ex
(RU) Изобретение относится к технологии получения химических веществ, используемых в изолирующих дыхательных аппаратах (ИДА) на химически связанном кислороде, и может быть использовано в производстве продуктов для регенерации воздуха на основе надпероксида калия. Регенеративный продукт для изолирующих дыхательных аппаратов включает надпероксид калия и силикат магния, полученный из хризотилового асбеста, при соотношении компонентов в составе регенеративного продукта, мас.%: надпероксид камера калия KO2 90-95; силикат магния MgSiO3 5-10. Способ изготовления регенеративного продукта для изолирующих дыхательных аппаратов заключается в смешении надпероксида калия с силикатом магния с последующим формованием смеси, при этом силикат магния получают из хризотилового асбеста воздействием температуры 800±20°С в течение 2-3 ч с последующим размалыванием в барабанной мельнице. После формования регенеративный продукт может быть подвергнут термостабилизации по режиму: нагрев до 200±20°С со скоростью 1-5°С/мин; выдержка при 200±20°С в течение 1-2 ч. Регенеративный продукт предложенного состава обеспечивает при работе в составе ИДА низкий показатель средней и максимальной объемной доли диоксида углерода на вдохе, низкую температуру регенерируемого воздуха на вдохе и большее время защитного действия. Это обеспечивает более комфортные условия для пользователя и позволяет существенно расширить круг лиц, которые могут пользоваться данными дыхательными аппаратами. 2 н. и 1 з.п. ф-лы, 1 ил., 2 табл., 3 пр.
