Insulation castable is a low volume density of refractory castable, with low volume density, small thermal conductivity, good thermal insulation effect and other characteristics. It is mainly made of aluminate cement, high aluminum fine materials, additives and other raw materials.
The high quality insulation castable has many advantages, such as good workability, strong adhesion, long construction operation time, strong impermeability and no need of acidizing treatment. Moreover, it can ensure the compactness and fullness of the mortar seam of the masonry, and significantly improve the air tightness, integrity and corrosion resistance of the lining, it is an ideal cementing material for lining of high chimney, high temperature flue and air duct.
This type of refractory castable volume light, high compressive strength, acid and acid gas corrosion resistance, heat insulation, heat preservation, low water absorption. It is widely used in electric power, petrochemical, metallurgy, kiln and other industries. Also can be used in nonferrous metallurgy industry such as acid – resistant pool and acid – resistant engineering. Generally used as a refractory lining and double lining insulation and similar thermal equipment insulation insulation castable.
When making and using insulation castable, it should be prepared according to the design, and then carry out the test of normal temperature compressive strength and volume density inspection. Only after passing the test can it be put into use. We have a professional technical team in the production and construction of the castable, experienced, service in place, welcome to have the need to purchase customers to consult our products.
