Low thermal conductivity, high quality, lightweight thermal insulation mullite brick
Low thermal conductivity, high quality, lightweight thermal insulation mullite brick, mainly based on aluminum silicate-based refractory materials, with some excellent performance, (especially high temperature creep performance) living in natural raw materials production Of the high aluminum products first.
Low thermal conductivity, high quality, lightweight thermal insulation mullite brick,Mullite composition AL203 in about 79%, Si02 in 21% is more appropriate, but there are a certain amount of raw materials in the impurity composition, at high temperatures will cause the composition of the composition, so as the impurity composition increases, will make vitreous and corundum And the molybdenum is formed into coarse grain structure, which makes the porosity of the product increase, the thermal shock stability and corrosion resistance are reduced, and cracks are likely to occur.
Low thermal conductivity, high quality, lightweight thermal insulation mullite brick ccording to the different use of temperature production of multiple grades of mullite lightweight insulation brick is divided into WAM23 / WAM26 / WAM28(JM23/ JM26/ JM28/ JM30), the use of temperature range from 1100C-1650C, the ratio of each product is specially designed to meet the different thermal and Physical requirements.
Characteristics of Low thermal conductivity, high quality, lightweight thermal insulation mullite brick
Low thermal conductivity, high quality, lightweight thermal insulation mullite brick with the characteristics of High strength, high impurity content; high temperature, can be directly exposed to the flame (this is very important), resistant to various atmosphere corrosion; low thermal conductivity, low melting; high strength, and excellent thermal shock resistance; high dimensional accuracy.Physical&Chemical Index Low thermal conductivity, high quality, lightweight thermal insulation mullite brick:
