What are the types of ceramic fiber products?

Ceramic fiber products are a kind of fibrous lightweight refractory material, its diameter is generally 2-5μm, the length is mostly 30-250mm, and the fiber surface is smooth and cylindrical. Due to its lightweight, high-temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and mechanical vibration resistance, it is widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, glass, electronics,,s and other industries.

What are the types of ceramic fiber products?

The main types of ceramic fiber products include ordinary aluminum silicate fiber, high aluminum silicate fiber, aluminum silicate fiber (Cr2O3, ZrO2), polycrystalline alumina fiber, and polycrystalline mullite fiber. In recent years, foreign countries have successfully developed (or are developing) some new ceramic fiber varieties, such as forsterite fiber, ceramic fiber (SiO2-CaO-MgO system and Al2O3-CaO system), etc. Ceramic fiber cotton, felt, blanket, module, paper, cloth, belt, rope, etc.

Ceramic fiber blanket

Ceramic fiber blankets (fiber modules) are mostly made of self-melting, continuous melting and continuous spinning production processes to produce long fibers, which are interwoven by double-sided needle punching and can be directly used as flame-hot surfaces. They integrate fire resistance, heat insulation, and thermal insulation. They can maintain good strength and toughness in neutral, oxidizing, and reducing gases for long-term use. Fiber modules made of this fiber blanket do not contain binders and have good thermal stability. They are widely used in thermal insulation and heat-resistant fields such as petrochemicals, metallurgy, and electricity.

Ceramic fiber board

Ceramic fiberboard is made of ceramic fiber, binder, and additives through pulping, molding, curing, and drying. Ceramic fiberboard is flexible, easy to cu,t, and high in strength. It is a new energy-saving and environmentally friendly product with low thermal conductivity and low heat storage. It is widely used in the backing of walls and ceilings of various heating equipment and is a heavy refractory material. Ceramic fiber cloth and tape are mainly used for fire doors, industrial furnace insulation, high-temperature pipes, and containers. Ceramic fiber rope is mainly used for expansion joints of various industrial furnaces, winding insulation of high-temperature pipes, and insulation of steel structure joints.

Ceramic fiber paper

Ceramic fiber paper is made of ceramic fiber, binder, and additives, and is made through pulping, molding, curing, and drying processes. It is an ideal material for sealing and heat insulation. It can be used for thermal insulation of various thermal kiln expansion joints, high-temperature gaskets, and other parts. In addition, ceramic fiber can also be used for filtration and catalyst carrier materials, filling materials and friction materials, thermal insulation coatings, reinforcement materials, etc.

High silica fiber product

High silica fiber is also a kind of ceramic fiber that performs excellently. It is a glass fiber with high SiO2 content made by acid treatment and heat treatment of ordinary alkali silicate glass fiber. Its long-term use temperature is above 1000℃.

Quartz fiber

Quartz fiber produced by the melting method is a kind of ceramic fiber with excellent performance, but it is generally not used as thermal insulation material due to its high price. Coating Si and Al on quartz fiber can further improve its thermal insulation performance. Used quartz fiber products can also be recycled by crushing the waste quartz fiber insulation products, mixing them with water and binder, and molding them into high-temperature insulation products.
