Antimony impregnated graphite ring is a special composite sealing element made by impregnating antimony or its alloy into a graphite matrix.
1. Product Introduction
Antimony impregnated graphite ring is a special composite sealing element made by impregnating antimony or its alloy into a graphite matrix. This material combines the excellent properties of graphite, such as high temperature resistance, corrosion resistance and self-lubrication, with the strength and wear resistance of antimony alloys, thus showing excellent performance in certain specific industrial applications.
2. Materials and characteristics of antimony impregnated graphite ring
Material composition
Antimony impregnated graphite ring is mainly composed of high-purity graphite matrix and antimony alloy impregnant. The graphite matrix is based on its high thermal conductivity, good electrical conductivity and chemical stability, while the antimony alloy impregnant is filled into the pores of the graphite matrix through the impregnation process and tightly combined with the graphite matrix to form a composite material that is both hard and elastic.
Characteristics
(1) High temperature resistance: The graphite matrix has excellent high temperature resistance and can maintain stable performance for a long time under high temperature environment. The antimony alloy impregnant can also maintain stable performance within a certain temperature range, further enhancing the high temperature resistance of the antimony impregnated graphite ring.
(2) Corrosion resistance: The graphite matrix has good corrosion resistance to most chemical media and can resist the erosion of various corrosive media such as acids, alkalis, and salts. The antimony alloy impregnant also enhances its ability to resist chemical erosion, allowing the antimony impregnated graphite ring to operate stably for a long time in corrosive media.
(3) Self-lubrication: Graphite itself has good self-lubrication and can reduce wear and friction heat during friction. The addition of antimony alloy further enhances this lubricity, making the antimony impregnated graphite ring perform well in the sealing of rotating and reciprocating moving parts.
(4) Excellent sealing performance: The antimony impregnated graphite ring has a smooth surface and precise dimensions, and can form a tight fit with the matching material to achieve a good sealing effect. At the same time, its self-lubrication can also reduce the friction and wear of the sealing surface and extend the service life.
3. Application fields of antimony impregnated graphite rings
Antimony impregnated graphite rings are widely used in the following fields due to their unique properties:
Petrochemical: In the petrochemical industry, antimony impregnated graphite rings are often used as sealing components of equipment such as pumps, valves, and compressors. It can withstand high temperature, high pressure and corrosive media to ensure the normal operation of the equipment.
Power industry: In the power industry, antimony impregnated graphite rings are used for sealing and lubricating parts of equipment such as turbines and generators. Its high temperature resistance, corrosion resistance and good lubricity enable these equipment to operate stably in harsh working environments.
Mechanical manufacturing: In the field of mechanical manufacturing, antimony impregnated graphite rings are used as bearings, seals and other parts. Its excellent wear resistance and sealing performance can reduce the friction, wear and leakage problems of equipment and increase the service life of equipment.
4. FAQ

A: Antimony impregnated graphite rings have excellent high temperature resistance and can operate stably for a long time under high temperature environment. The specific high temperature resistance temperature depends on the performance of the graphite matrix and the antimony alloy impregnant.
Q: What is the corrosion resistance of antimony impregnated graphite rings?
A: Antimony impregnated graphite rings have good corrosion resistance to most chemical media and can resist the erosion of various corrosive media such as acids, alkalis and salts. The specific corrosion resistance depends on the performance of the graphite matrix and the antimony alloy impregnant and the type of medium in contact.
Q: How to maintain the antimony impregnated graphite ring?
A: The maintenance of the antimony impregnated graphite ring mainly includes regular cleaning, checking whether the sealing surface is worn or damaged, and replacing the damaged antimony impregnated graphite ring. During use, the antimony impregnated graphite ring should be avoided from direct contact with hard objects to avoid scratching the surface. At the same time, it is also necessary to keep it dry and clean to extend its service life.
