REGENERATIVE PRODUCT FOR ISOLATING RESPARATORY APPARATUSES Russian patent published in 2015 - IPC A62D9/00 B01J20/04 B01D53/62 

FIELD: chemistry.

SUBSTANCE: product for air regeneration has the following composition, wt %: potassium superoxide 88, magnesium sulfate 6-10; silicon dioxide, synthesised from chrysotile asbestos, 6-2. Regenerative product of the given composition provides high absorption of carbon dioxide and even release of oxygen per weight unit during the entire tome of product operation in cartridge of isolating respiratory apparatus, as well as high degree of service when it is exploited in isolating respiratory apparatus in comparison with analogues due to improvement of conditions of water vapour and carbon dioxide diffusion into volume of product granules. It makes it possible to increase time of protective action of isolating respiratory apparatus with the same weight-size characteristics. In addition, isolating respiratory apparatus, equipped with claimed regenerative product, has lower temperature of circulating air at inhalation and considerably lower aerodynamic resistance to user's respiration.

EFFECT: more comfortable conditions for user, and makes it possible to considerably extend group of people able to use said respiratory apparatuses.
