Benefits of technology

The present invention relates to an improved design for a seal used in electronic devices. This improvement includes reducing the amount of water needed by the seal while maintaining its performance. Additionally, there may also include adding certain materials like boron nitrides or polytetrafluoroethylene resins to improve thermal conductivity without affecting fluidity. By mixing these materials together, the resulting mixture has better properties than just one component alone.

Problems solved by technology

This patent describes a technical solution for improving the performance of a joint between two parts of a pipe system when subjected to high temperatures during operation. One part of the pipeline is equipped with a special type of gasket called a heat-resistant sheet. Another part of the pipeline is protected against damage caused by excessive pressure waves generated by the engine's movements. Additionally, the patent suggests adding another layer of anti-friction material onto the surface of the gasket to reduce frictional sound and improve its effectiveness over time.

Abstract

Provided is a gasket capable of maintaining a high sealing property under a high temperature, in which a gasket basic substance and coverture are not sublimated or decomposed when the gasket is used under a high temperature above 500° C. The gasket for a high-temperature joint includes a gasket basic substance formed by filling a heat-resistant filler mainly composed of diatomaceous earth into gaps of a meshed metallic reinforcing member, and coverture made of a heat-resistant antifriction material mainly composed of a mixture of boron nitride and polytetrafluoroethylene resin for covering a surface of the gasket basic substance.
