High Alumina Refractory Mortars Power Shape Mortars
The Description:
High aluminum fire mud is a kind of resistant material product after mixing water into paste mud, which can also be called high aluminum refractory mud, and is the joint material of high aluminum fire brick.
High alumina pyroclay is a powder bulk material composed of high bauxite clinker, soft clay, binder and admixture, which belongs to semi-finished product. It belongs to hydraulic bonded refractory mud. When it is used, it is stirred with water and has a qualitative strength and high temperature resistance effect after heating. Its particle size is based on the requirements of use, generally using 180-200 mesh, is the product of high aluminum brick masonry joints.

Application:
High Alumina Refractory Mortars Power Shape Mortars used in thermal insulation layer(preheater,decomposing furnace,tertiary duct,kiln hood,coller,etc)
The Feature:
1, the chemical stability of high aluminum refractory mud is good, at high temperature and furnace gas, slag does not react chemically, does not produce erosion, not easy to peel and powder, can maintain its protective effect for a long time.
2, high aluminum refractory mud has good thermal stability, strength and wear resistance at high temperature are not reduced, it is not easy to soften, crack and flake, and can maintain its physical and mechanical properties for a long time.
3, high aluminum refractory mud has low water absorption, low water absorption at high temperature, high porosity, good slag resistance, strong erosion resistance, and can maintain its use effect for a long time.
4, high aluminum refractory mud volume stability and load softening temperature is high, good volume stability at high temperature, will not be affected by heat deformation and use effect.
5, high aluminum refractory mud has low thermal conductivity, low thermal conductivity at high temperature, which can reduce the heat loss of the furnace lining and reduce the production cost.
