Research on the Application of Melamine Sulphonate（MS） in Monolithic Refractories

Through research on the application of MS in monolicthic refractiories,the authors found that the absorptive style of MS is Lang-muir constant temperature absorption,the maxmium absorption is 20 mg/g in the mono-lithic refractories with pure calcium aluminte cement as binder,When the additive quantity is between 0.5% to 1.0%,the cold crushing strength of castable refractoies is 100% to 230% more than ordinary sample ,the modulus of rupture is 80% to 200% more,the bulk den-sity is 6% to 9.5% more and the porosity decrease by 15% to 36% than ordinary sampl,The authors consider tha MS is a kind of excellent high molecular compound in monolithic refractories.
