With the continuous advancement of science and technology, in addition to traditional shaped refractory insulation materials, ceramic fiber has gradually become a new type of refractory insulation material for industrial furnaces with a wide range of uses.
Ceramic fiber, also known as aluminum silicate, is a fibrous lightweight refractory material with light weight, high temperature resistance, low thermal conductivity, and small thermal melting. Ceramic fiber products include: ceramic cotton, ceramic fiber blanket, ceramic fiber shell, ceramic fiber board, ceramic fiber calcium silicate board.
Ceramic fiber products 1: ceramic fiber blanket. This product is processed by high-temperature melting of raw materials or silk-spinning acupuncture, and is processed by double-sided acupuncture. The color is white, and it integrates fire resistance, heat insulation and heat preservation. The use of ceramic fiber blankets in a neutral, oxidizing atmosphere can maintain good tensile strength, toughness and fiber structure. It has heat insulation and fire protection, low heat capacity, low thermal conductivity, excellent chemical stability, excellent thermal stability, excellent tensile strength and sound absorption performance, and is not easy to corrode. It is mainly used for high-temperature pipelines, industrial kiln wall linings, backing materials, thermal energy equipment insulation, high-temperature environment filling insulation, kiln masonry expansion joints, furnace doors, roof insulation and sealing, etc.
Ceramic fiber products 2: ceramic fiber shell. The raw material of the aluminum silicate shell is aluminum silicate, which is made of collodion felt and processed by mold processing, drying, curing, molding and other processes. Features: 1. Low thermal conductivity and low heat capacity. 2. Good shock resistance and good thermal stability. 3. Excellent processing performance. 4. Make the construction more convenient and faster. The specifications, inner diameter and density of aluminum silicate shells can be made according to customer needs. Widely used in heat preservation of heat pipes in chemical industry, coking, power plants, ships, heating and so on.
Ceramic fiber products 3: ceramic fiber tube sheet.
Ceramic fiber board is made of ceramic fiber of corresponding material as raw material, and is made by dry forming process of ceramic cotton board. It has the characteristics of thermal insulation, fire prevention, good toughness, light bulk density and corrosion resistance. Moreover, it does not expand when heated, is easy to construct, and can be cut at will. It is mainly used as an ideal energy-saving and environmentally friendly material for kilns, pipes and other insulation equipment.
Nowadays, ceramic fiber products have become the main energy-saving and thermal insulation materials for more high-temperature kiln projects. Not only that, but also in the “insulation and decoration integrated board” and “structural insulation integrated steel wire grid board”, the role of ceramic fiber is also It began to stand out. For example, the inner core is made of ceramic wool board. The ceramic wool insulation and decoration integrated board not only makes the outer wall play a decorative role, but also effectively guarantees the indoor temperature, and plays the role of heat insulation and fire prevention.
