GASKET Russian patent published in 2008 - IPC F16D69/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to components used for separation of stacked porous plates in production process. Circular gasket is made of carbon material whereon an adhesive coat layer is applied and incorporates opposed first and second surfaces. Note that at least one of the said surfaces has multiple radial channels each passing between the gasket inner and outer radial sides to inter-joint them. Method of preparing circular carbon fiber blanks for chemical filtration in vapor phase consists in stacking the aforesaid carbon fiber blanks. Between every two circular blanks, a circular metal screen cushion is laid so as to make stacked circular blanks and circular gaskets form interfaces of internal space inside a stack. Every aforesaid circular gasket comprises adhesive coat layer applied thereon to prevent sticking of circular carbon blanks. Method of producing one-piece circular carbon-material gasket consists in forming one-piece circular carbon-material gasket with opposed first and second surfaces and radial channel and applying adhesive coat layer on the said circular gasket.

EFFECT: updating production process.
