Properties of aluminum silicate fiber

Properties of aluminum silicate fiber

Aluminum silicate fiber is a kind of fibrous lightweight refractory material, excellent performance in the field of industrial high temperature insulation.

High refractoriness: above 1580℃;

Small volume weight: light volume density to 128Kg/m³:

Low thermal conductivity :1000℃ can be as low as 0.13w/(m.K), good insulation effect;

Small heat capacity: intermittent furnace rising and cooling fast and energy saving;

Fiber porous structure: good thermal shock resistance, no oven; Compressible, good elasticity, to create the whole furnace lining; Heat insulation sealing gasket;

Good sound absorption: different decibels have good noise reduction ability;

Good chemical stability: generally do not react with acid and base, not affected by oil corrosion;

Long service life;

Various product forms: loose cotton, rolled felt, rigid board, cloth belt rope, suitable for different application fields;

Special-shaped shapes can be customized.

Ordinary ceramic fiber is also called aluminum silicate fiber, because one of its main components is alumina, and alumina is the main component of porcelain, so it is called ceramic fiber. Adding zirconia or chromium oxide can further increase the temperature of ceramic fiber.

Ceramic fiber products refer to the use of ceramic fiber as raw materials, through processing made of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance advantages of industrial products, specially used in a variety of high temperature, high pressure, easy wear environment.

Ceramic fiber products are a kind of excellent refractory materials. It has the advantages of light weight, high temperature resistance, small heat capacity, good thermal insulation performance, good thermal insulation performance, no toxicity and so on.

There are more than 200 ceramic fiber manufacturers in China, but the production process of ceramic fiber with the classification temperature of 1425℃ (including zirconium fiber) and below is only divided into two kinds of silk blanket and spray blanket.
