Ceramic fiber blanket has high thermal efficiency, and nano-ceramic fiberboard can improve the particularity of chemical substances. Its application has been constantly improved. Nowadays, people are increasing its application, and it will also report to customers the saving of raw materials and energy. It is tough at high temperature, where the load-bearing capacity is relatively high. It has high air velocity, easy to damage mechanics, strong corrosion resistance of ceramic fiber blanket, and can be well used in high temperature and other environments. Therefore, ceramic fiber blanket is welcomed by people.
