Casquillo cerámico de nitruro de boro de 300 mm de diámetro

En Casquillo cerámico de nitruro de boro de 300 mm de diámetro is a high-performance ceramic component, which is made of high-purity boron nitride (BN) material, and has excellent high temperature resistance, corrosion resistance, insulation and self-lubricating properties. This bushing is specially designed for extreme working conditions, and is suitable for high temperature, high pressure and strong corrosive environments. It can effectively replace traditional metal or ordinary ceramic bushings, significantly improving equipment life and operating stability.
Key characteristics
-Resistencia a altas temperaturas: it can work stably in an environment above 1000 ° C for a long time, and can withstand temperature up to 1800 ° C in a short time.
-Bajo coeficiente de dilatación térmica: excellent thermal stability, reducing the risk of deformation or cracking caused by temperature changes.
-Inercia química: It has strong resistance to most acids, alkalis, molten metals and corrosive gases.
-Self lubrication: low friction coefficient (0.2~0.4), reduce wear and prolong service life.
-Alto aislamiento: excellent electrical insulation performance, suitable for electronic, semiconductor and other industries.
-Alta resistencia mecánica: high compressive and bending strength, suitable for high-pressure environment.
