Step 4：Particle, mesopore molecular sieve, aerosil and the gelling agent of 0.60-1.60mm obtained above is put into stirring
In machine, and suitable quantity of water is added and stirs evenly, slurry injects in mold, after the forming under the pressure of 5.0-10.0MPa, pressurize 3min
Demoulding, dry 48 obtained crude green bodies；
Step 5：Crude green body after drying is entered into klining at firing temperature is 1130 DEG C -1190 DEG C, keeps the temperature 1.5-4.5h, the burning
It is at temperature concrete operations:Heating rate is 1.5 DEG C/min when less than 400 DEG C, at 400-800 DEG C heating rate be 1.0 DEG C/
Min is 3 DEG C/min after 800 DEG C, and keeps the temperature 1.5-4.5h to get to the sound-absorbing porous material for building.
