Aluminum silicate fiber, also known as ceramic fiber, is a new type of lightweight refractory material. Clinker is used as raw material, melted through resistance or electric arc furnace, and blown into fiber production process.
This material has the advantages of light weight, high temperature resistance, thermal stability, low thermal conductivity, small heat capacity, good mechanical vibration, good heating and insulation performance, and good expansion. It is made of aluminum silicate fiber board, aluminum silicate fiber felt, aluminum silicate fiber felt, and aluminum silicate fiber felt products through special treatment. Model sealing materials have the characteristics of low thermal conductivity, high temperature resistance, light weight, long service life, high tensile strength, good elasticity, and non toxicity. They are a new type of material that replaces asbestos and are widely used for insulation and heat preservation in industries such as metallurgy, power, machinery, and chemical engineering.
Technical features:
Low thermal conductivity, low heat capacity, high thermal stability and resistance to thermal shock, high compressive strength, good toughness, excellent corrosion resistance, and excellent processing performance.
Composite aluminum magnesium silicate insulation material is made of materials such as palygorskite, sepiolite, bentonite, ceramic fibers, etc. Using mechanical materials as the main raw material. Composite insulation materials are alkaline materials made of aluminum magnesium silicate with a pH value above 9, which can corrode steel and non-ferrous metal materials.
The density of the composite aluminum magnesium silicate insulation material is: superior grade equal to or less than 180kg/m3, first-class grade equal to or less than 220kg/m3. The National Building Materials Testing Center has tested the product with a thermal conductivity of 0.080-0.082 at 350 ℃ (the international standard/t17371 specifies a thermal conductivity of 0.11 at 350 ℃), so it has greater advantages in high-temperature insulation materials. Under the same conditions,
The market for magnesium aluminum silicate insulation materials with similar material thickness can range from 3-20%. The insulation performance, especially high temperature and excellent thermal performance, reduces the thickness of the insulation layer and also reduces the amount of land.
