The ceramic fiber blanket is made of silk fiber by the silk fiber forming process, and the double-sided needle punching process is fiber interweaving to produce a ceramic fiber blanket which is insulated, heat-insulated and fire-resistant. In the process of producing ceramic fiber blankets, ceramic fiber blankets without binders can maintain good flexibility and tensile properties even when used in neutral, chemical and partial reduction environments. Good thermal stability period is widely used in steel, chemical, metallurgical and other industries. In the identification of the fineness of the ceramic fiber blanket, it is usually used to identify by measuring its volume. The ceramic fiber blanket with a weight of about 100 kg per cubic meter will not exceed 100 kg. This method is more suitable for consumers to use in the field at the time of purchase. Of course, this method may have certain deviations. If consumers want more accurate data, they can go to the specified detection unit to identify.
The ceramic fiber blanket not only has the characteristics of heat preservation, heat insulation and fire resistance, but also has the characteristics of sound insulation and noise prevention. The inner fiber of the ceramic fiber blanket is fluffy and interlaced, and there are a lot of tiny pores. It is a typical porous sound absorbing material and has good sound absorption characteristics. Therefore, the ceramic fiber blanket can be used as a sound absorbing body on a ceiling or a wall surface to absorb noise in the room and reduce reverberation time. The attractive properties of ceramic fiber blankets are related not only to thickness and bulk density, but also to factors such as cover material and structural structure. In the construction application, it is also necessary to take into consideration various aspects such as cost, beauty, fire prevention, moisture resistance, dust, and aging resistance.
