Ceramic fiber products can significantly enhance equipment performance during long-term use by providing excellent thermal insulation, reducing heat loss, and maintaining operational temperatures. They help in energy conservation by minimizing heat transfer, which can lead to reduced fuel consumption and lower emissions. Additionally, they protect equipment from extreme temperatures, reducing the risk of thermal stress and fatigue, which can extend the lifespan of machinery. However, it's important to monitor the condition of ceramic fiber products over time, as they can degrade due to continuous exposure to high temperatures, leading to a loss of insulating properties and potential safety hazards. Regular maintenance and replacement are crucial to maintain optimal performance and safety.
