Aqua, dispersing agent continues to mix uniformly in blender；Add mobility when electrodeless colloidal sol helps to improve mixture casting；
The additive amount that cement can be reduced improves the corrosion resistance and creep strength of inner lining material；Obtain good construction spirit
Active and uniform fine powder distribution, and ideal phase is formd at relatively low temperature, show good resistance to flaking
Can, mould material can be made to form fine and close institutional framework after firing, there is good waterproof effect, prevent the infiltration of chilled water (chw)
Thoroughly.Addition magnesia often causes volume expansion, and caused by being typically due to magnesia aquation, and volume expansion is in processing rank
Duan Youhui causes crack, and appropriate citric acid is added in castable can reduce the adverse effect and machine of the generation of magnesia aquation
Tool intensity increases 3 times compared with the sample of no citric acid.By apparent volume expansion test and thermogravimetric analysis evaluation it is found that
Under aquation experiment condition (50 DEG C, place 7 days under high humidity environment), the addition of citric acid reduces magnesia aquation rate.
Step 3: the mixture that step 2 obtains further is uniformly mixed by high speed kolleroang；
Step 4: can be poured as required after the water for the mixture aggregation weight 5-6% that step 3 obtains is mixed
Molding, will pour the maintenance carried out in the present wet environment of sample being poured in 20 hours, then 20 hours dry in air again, so
Afterwards again 100 DEG C dry 18 hours, finally 1000-1100 DEG C carry out 1.5 hours be burnt into.
Preferably, the incorporation time of the step 3 is 25-35 minute, in this time frame it is interior can achieve it is best
