What is the difference between the national standards for ceramic fiber products and ordinary aluminium silicate?
Ceramic fiber products (aluminum silicate fiber products) in recent years, ceramic fiber products (aluminum silicate fiber products) in the application of high temperature sintering furnace expanding, ceramic fiber products (aluminum silicate fiber products) refractory felt and blanket products, the highest use temperature up to 1649 DEG C. Ceramic fiber products (aluminum silicate fiber products) to heat insulation effect is good, easy to use, especially small heat storage characteristics, widely used in various kilns, greatly demonstrated high energy efficiency. Ceramic fiber products (aluminum silicate fiber products) (1) ceramic fiber products (aluminum silicate fiber products) varieties and properties of ceramic fiber products (aluminum silicate fiber products) is the most important indicator of fiber diameter and thermal stability. Al2O3SiO2 fiber is commonly used in ceramic industry. It is divided into different application range according to the content of Al2O3, and Cr2O3 material is introduced into it to improve its refractory and oxidation resistance.
Generally high alumina content, iron oxide and other impurities of low fiber products are pure white, the introduction of chromium oxide fiber is sold with milk yellow tone color. The average diameter of ceramic fiber products (aluminium silicate fiber products) is 22 - 33 microns. High fiber, small density, low thermal conductivity, high temperature. If the fiber is coarse and dense, the use is not satisfactory. The thermal stability index of ceramic fiber products (aluminum silicate fiber products) is more important. The range of Al2O3SiO2 fiber contraction in various products of 1260 C line is 35 - 88%. The amount of shrinkage is also directly related to thermal stability. Ceramic fiber products (aluminum silicate fiber products) as ceramic fiber products (aluminum silicate fiber products) with low thermal conductivity, low density, light weight, light steel frame are used in the design and construction of kilns supporting structure, so that the development of ceramic kiln kiln into the "lightweight" era. The fiber has small heat storage and is suitable for quick heating and cooling firing.
