Definitions

  • This invention relates to the field of gasket, particularly directs to a ready to use gasket.
  • a gasket is a mechanical seal that fills the space between two mating surfaces, especially between two flanges, generally to prevent leakage from or into the joined objects while under compression.
  • gaskets there are numerous types of gaskets, among which solid gaskets and form-in-place gaskets are two of the most common varieties of gasket.
  • Solid gaskets are formed of solid materials, typically cork, cardboard, fabric, graphite, metals etc. We call them solid gaskets (or solid material gaskets). Solid gaskets are easy to handle and user friendly, but they can not be used to achieve 100% sealing, because solid materials do not go into micro imperfections between two flange surfaces.
  • FIP gaskets form-in-place gaskets
  • FIP gaskets liquids or sealants that cure after the parts are assembled. Since liquids or sealants go into micro imperfections between surfaces, FIP gaskets can achieve 100% sealing. But FIP gaskets require dispensing equipments, usually along with robotic systems, which means more investment. Moreover, handling sticky liquids or sealants at assembly lines is troublesome.

  • gasket refers to a mechanical seal that fills the space between two mating surfaces, such as the facing surfaces of two flanges.
  • a gasket is generally used to prevent leakage from or into the joined objects while under compression. Gaskets allow "less-than-perfect” mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials, such as gasket paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or a plastic polymer (such as polychlorotrifluoroethylene). Gaskets for specific applications may contain asbestos. It is usually desirable that the gasket be made from a material that is to some degree yielding such that it is able to deform and tightly fills the space it is designed for, including any slight irregularities.

As a result, a ready to use gasket was obtained.
  • Example 3 using the ready to use gasket in assembling flanges
  • the metal surface to be in contact with the gasket was cleaned. Surface contaminants were removed, and surface treatments were conducted. Once the surface was dry, the release liner of the ready to use gasket was removed, and the gasket was mounted on the flange, with its exposed adhesive layer facing and in contact with the metal surface to be bonded. Afterward, the other release liner of the ready to use gasket was removed.
  • the above flange with a ready to use gasket was installed on a mating flange, with the ready to use gasket sandwiched between the mating surfaces of two flanges.
  • the ready-to-use-gasket prepared as described in example 2 was assembled to a sealing testing fixture and allowed 24 hours curing time at room temperature. After curing air pressure was applied to the test fixture, immersed in water and checked for any leakage. Up to an applied air pressure of 20bar, no leakage was observed. This indicates excellent sealing performance as compared to conventional gaskets dressed with grease or shellac.
