(2) stir: Xian Jiashui stirs separately, and then mix and blend also adds other surplus stocks in the raw material by weight;
(3) cast: the slurry that step (2) is stirred adds in the stock mould, obtains the brick idiosome;
(4) rest: the brick idiosome of step (3) is put into the chamber of resting, rest chamber sealing thermal insulation 45-48 ℃, rested time 3-3.5 hour;
(5) cutting: the brick idiosome that step (4) is rested is put into and is processed into certain desired size on the cutting machine;
(6) steam-cured: that the green compact of above-mentioned steps (5) at 0.8-1.1Mpa vapor cure 16-18h, are namely got the aerated bricks finished product.
Described modified straw ash is that straw ash is admixed the calcium lignin sulphonate agitating with dioctyl maleate, 1-2% that is equivalent to powder weight 1-2% is even, and oven dry is ground into 180-250 order powder and obtains.
Beneficial effect of the present invention:
The present invention is by adopting municipal sludge and modified straw ash as the composition of aerated bricks, and is with low cost, turns waste into wealth, and consumption is large, has protected environment; Reduced energy consumption; Modified kaolin has been optimized starting material, and the aerated bricks that makes is heat insulation all good with sound-proofing properties, and existing aerated bricks is significantly improved; Simultaneously the present invention is by the optimization of C/C composites materials, and intensity of the present invention, frost resistance are significantly improved.
