2. Materials and characteristics of Impregnated Metal Graphite Ring
Material composition:
Impergated Metal Graphite Ring is composed of high-purity graphite matrix and metal impregnant. The graphite matrix is based on its excellent chemical stability, self-lubrication and high temperature resistance, while the metal impregnant penetrates into the pores of the graphite matrix through a vacuum impregnation process to form a hard metal skeleton, thereby greatly improving the wear resistance and mechanical strength of the graphite ring.
3.Characteristics
(1) High wear resistance: The metal impregnant forms a strong skeleton in the graphite matrix, which makes the impregnated metal graphite ring have extremely high wear resistance and can operate stably for a long time under high load and high speed conditions.
(2) Good thermal conductivity: Graphite material itself has excellent thermal conductivity, and the metal impregnant further improves its thermal conductivity efficiency, so that the metal-impregnated graphite ring can quickly dissipate heat when subjected to high temperature, ensuring the temperature stability of the sealing surface.
(3) Excellent sealing performance: The metal-impregnated graphite ring has precise dimensions and a smooth surface, which can form a tight fit with the matching material to achieve a good sealing effect.
(4) Chemical stability: The graphite matrix has good chemical stability and can resist the erosion of various chemical media, ensuring the long-term stable operation of the metal-impregnated graphite ring under complex working conditions.
