STRENGTHENED GLASS VESSEL (VERSIONS) AND GLASS VESSEL STRENGTHENING METHOD (VERSIONS) Russian patent published in 2019 - IPC C03C17/25 C03C17/32 B82Y40/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a method of producing strengthened glass vessels. According to the first version, the surface of the vessel is coated with at least one reinforcing layer having thickness of 5–50 nm, containing tin dioxide or titanium dioxide, and single-wall carbon nanotubes, with content of 0.05–1 wt%. At that, reinforcing layer is applied on hot end of process line on surface of molded vessel, having surface temperature of 450–750 °C. According to the second version, the surface of the vessel is coated with at least one reinforcing layer having thickness of 40–100 nm, containing a polymer base in the form of modified polyethylene, and single-wall carbon nanotubes at their content of 0.05–0.2 wt%. Reinforcing layer is applied at the cold end of the processing line, at the vessel surface temperature of 80–120 °C.

EFFECT: high strength of glass vessels.
