METHOD FOR HERMETIC SEALING OF CYLINDRICAL AND SPHERICAL SHEETS OF COMPOSITE MATERIALS

摘要

manufacture of pipes, vessel and other products of composite materials operating in chemically aggressive and abrasively active media. SUBSTANCE: method provides for connection of the protective layer of rubber with the construction layer of glass-reinforced plastic. Layers of low-density material are wound on the protective coating of rubber wound on a metal mandrel with an applied antiadhesion layer. A construction layer is formed over it with subsequent polymerization of the shells, providing for a strong (up to 12 kgf/cm) adhesion binding of protective coating-glass-reinforced plastic. EFFECT: strong and reliable adhesion binding between layers.
