Optimal thickness of the coating Shell of silicon carbide based on the study of barrier function

Justification of optimum thickness of a covering "Armour" from silicon carbide on the basis of studying of its barrier function to potentially dangerous products of migration from stomatologic the polimetilmetakrilatnykh ofplastic for basis of artificial limbs on the example ofstomatologic polimetilmetakrilatny plastic ("Ftoraks" of Stoma, Ukraine") with the different thickness ofa covering (800, 1600 nanometers) proved protective properties of a covering "Armour" from silicon carbide which reduces migration levels from bases of the artificial limbs made of them, potentially dangerous connections. The covering "Armour" 800 nanometers thick by 1,45 times passes less MMA in comparison with the samples unprotected by a covering, and 1600 nanometers thick (approximately by 49 times) is 2-6 times less than maximum concentration limit. Reducing levels of migration ofpotentially dangerous products, especially with a covering of 1600 nanometers, the covering "Armour" reduces chemical risk factor of use of the materials "Ftoraks" on appointment.
