Product introduction
Aluminum silicate refractory mortar includes clay based refractory mortar, mullite based refractory mortar, high alumina based refractory mortar and so on. accordingly, the matrix materials of aluminum silicate refractory mortars are clay clinker fines, sintered or fused mullite fines, high alumina bauxite clinker fines, sintered or fused corundum fines. During making aluminum silicate mortar, some quantity of soft clay, bonder and additives are added into the matrix. The function of soft clay is to improve the workability of the mortar, such as spread ability and adhesion ability, etc. Silica micro powder can be used to replace soft clay to enhance workability
Binding agent is required to improve the strength of aluminum silicate refractory mortar. There are two types of binders: 1) silicate series, i.e. water glass with different modulus of (SiO2/Na2O). 2) Phosphate series, such as acidic aluminum phosphate and polyphosphate, etc. The quantity of binders is decided by applications. Generally speaking, the more the binder, the higher the sintered binding strength. But at high temperature, the case is the opposite, because binders appear liquid phase at high temperature.
