Ceramic Fiber Paper

Raw materials

The main raw material of ceramic fiber paper is ceramic fiber, which is an inorganic fiber material obtained by high-temperature melting and fiberization of natural minerals or chemical raw materials such as kaolin, silica, and alumina. These raw materials have the characteristics of high purity, high temperature resistance, and good chemical stability, which lays the foundation for the high performance of ceramic fiber paper.

Production process

First, the ceramic fiber raw materials are pre-treated by opening and combing to make them loose fibers. Then, the fibers are mixed evenly with an appropriate amount of binders, additives, etc. to make fiber slurry. Then, the papermaking technology in the papermaking process is used to make the fiber slurry into wet paper sheets with a certain thickness and strength on the papermaking machine. Finally, through post-treatment processes such as drying and curing, the moisture and volatiles in the paper sheets are removed, and the binder is cured, thereby obtaining ceramic fiber paper with certain properties.

Performance characteristics

1. Excellent high temperature resistance: It can be used for a long time in high temperature environment and can withstand high temperature above 1000℃. The operating temperature of some high-performance ceramic fiber papers can reach 1200℃ - 1400℃, which makes it widely used in high temperature industrial fields.

2. Low thermal conductivity: It has extremely low thermal conductivity and can effectively prevent heat transfer. It is an excellent thermal insulation material. This feature can help industrial equipment and pipelines reduce heat loss, reduce energy consumption, and improve energy utilization efficiency.

Good chemical stability: It has good corrosion resistance to most acids, alkalis and other chemical substances, is not easily corroded by chemical substances, can maintain stable performance in harsh chemical environments, and can be used for thermal insulation protection of equipment and pipelines that contact chemical media in chemical, metallurgical and other industries.

3. Good flexibility: It has certain flexibility and processability, and is easy to cut, fold, curl and other processing operations. It can be made into products of various shapes and sizes according to different usage requirements, which is convenient for installation and use. It can be used in some parts that require flexible installation, such as the bends of pipes and the sealing parts of equipment.

4. Low bulk density: The bulk density is generally between 180 - 400kg/m³, which is lighter than other traditional insulation materials. This is not only convenient for construction and installation, but also can reduce the weight of equipment and structures. It has obvious advantages in some occasions with weight requirements.
