Zirconia Ceramic Gland Plate

Alias: High-Temperature Resistant Electrically Insulating Ceramic Sealing Washer / Wear-Resistant Zirconia Ceramic Shaft Sleeve / Sealing Ring

Description：

Zirconia ceramic compression rings, high-temperature insulating ceramic sealing gaskets, and wear-resistant mechanical shaft sleeves have excellent thermal shock resistance, corrosion resistance, high-temperature stability, and wear resistance. It is widely used in the manufacturing of components such as compression rings, sealing washers, and mechanical shaft sleeves. In fields such as chemical, aerospace, and energy, the application of zirconia ceramics improves the performance, reliability, and stability of equipment, especially in situations requiring high temperature resistance, insulation, and wear resistance.

Features:

— Thermal shock resistance

Thermal shock resistance, also known as thermal stability, thermal shock stability, thermal shock resistance, etc., refers to the ability of a material to resist damage when subjected to rapid temperature changes. Specifically, when a material experiences extreme temperature changes in a very short period of time, thermal stress occurs inside it, which can lead to cracking, peeling, or shattering of the material. Zirconia ceramics have excellent thermal shock resistance, can withstand thermal stress caused by temperature changes, and reduce cracks and damage caused by thermal shock.

— Corrosion resistance

In industry, corrosive media are often exposed, such as acid-alkali solutions, corrosive gases, etc., and zirconia ceramics have excellent corrosion resistance, can be used stably for a long time in harsh environments such as strong acids and alkalis, and are not easily damaged by corrosion.

— High temperature stability

In a high-temperature environment, materials may undergo various chemical reactions, such as oxidation, reduction, decomposition, etc., and will also undergo physical changes, such as phase transitions, lattice structure changes, etc., resulting in loss of stability or deformation, embrittlement and other problems; Zirconia ceramics have excellent high-temperature stability and can maintain stable physical and mechanical properties in high-temperature environments for a long time.

— Abrasion resistance

While traditional material components are subject to severe wear and tear under high-speed rotation and high-load work, zirconia ceramics have excellent wear resistance and can maintain stable performance in high-friction and high-wear environments.

Applications:

1. Chemical industry

1.1 Seal applications

In the chemical production process, a large number of seals are required to ensure the tightness of the equipment and prevent media leakage. Corrosion-resistant and high-temperature sealing gaskets made of zirconia ceramic can withstand working conditions in high-pressure and high-temperature environments, ensuring the safe operation of equipment.

1.2 Valves and piping systems

Valves and piping systems in chemical equipment are subject to the flow and pressure of the medium, so they need to have good corrosion resistance and high temperature resistance. Valves and pipe components made of zirconia ceramic can operate stably for a long time under corrosive media and high temperature conditions, reducing equipment maintenance costs and downtime.

2. Aerospace field

2.1 Aero engine components

In aero engines, a large number of high-temperature and wear-resistant parts are required to ensure the stable operation of the engine. Sealing rings, bushings, and other components made of zirconia ceramic can withstand high-temperature and high-speed operating conditions, improving performance and reliability.

2.2 Aerospace devices
