ApplicationNo./PatentNo.: 2007 102026 18
The invention relates to a new use of sodium silicate solution, phosphoric acid solution and refractory mud, which is mainly used for masonry under special conditions or masonry in special kilns. The new use of sodium silicate solution or phosphoric acid solution is as refractory slurry binder. The refractory mud comprises refractory powder and external binder, and is characterized in that the binder is sodium silicate solution or phosphoric acid solution, the addition amount of which is 30-60% of the weight percentage of the refractory powder, the concentration of the sodium silicate solution is 50-90%, and the concentration of the phosphoric acid solution is 50-80%. Sodium silicate solution or phosphoric acid solution has good viscosity at room temperature, which can improve the cohesiveness of refractory slurry and solve the problem of brick falling in special kiln construction. Effectively solve the problem of fast drying of fire mud when building refractory bricks with large porosity; The sintering performance of refractory mud is better, which can ensure the kiln to have better integrity at high temperature.
