Description
Technical field
The present invention relates to aerated bricks technical field, more particularly to a kind of system for adding the steaming-free air-adding brick for burning till plating slag mud
Preparation Method and preparation method thereof.
Background technology
Radiation is present in whole cosmic space, and source radiation has man-made radiation and natural radiation, and natural radiation includes universe
Ray, gamma-rays, radon, alpha ray, man-made radiation include being produced in the field application processes such as nuclear power, military affairs, education, scientific research, medical treatment
Raw various rays, cancer, leukaemia, bone marrow cancer, malignant tumour, thyroid gland machine can be induced by receiving these ray chronic exposures
Can a variety of incurable diseases such as disorder, while can also inducing plant gene mutation, harm the crops growth.Radiation On Human body in order to prevent
Injury, the building block generally in architectural process using radiation shield concrete or with radiation proof function.At present, the anti-spoke in China
Penetrating concrete technology of preparing includes 2 kinds：First, the high density materials such as barite, iron ore are used as the heavy concrete that gathers materials；
Second, use mineral admixture exploitation low porosity, the high performance concrete of high solidity.The former is due to natural radiation protection collection
Expect that density is big, the problem of mixture homogeneity is poor is being also easy to produce during construction casting；The quality of the latter's often shielding material declines
Weak pattern number is relatively low, need to improve the thickness of radiation shield concrete layer, makes its dead weight increase, and cost improves.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, there is provided a kind of 1 add burns till the non-evaporating of plating slag mud
Preparation method of aerated bricks and preparation method thereof.
The present invention is achieved by the following technical solutions：
1st, a kind of preparation method for adding the steaming-free air-adding brick for burning till plating slag mud, including step in detail below：
（1）The plating slag mud of zinc containing chromium crushed stand-by after 200 mesh sieves；Polyvinylpyrrolidone is dissolved in the 20-24 times of water measured,
It is heated to being completely dissolved forming solution, then solution is mixed with the plating slag mud of zinc containing chromium, suitable water content is controlled, then will
Mixture is sent into granulating disc and is granulated, and obtains plating slag mud particle；
（2）Plating slag mud particle is put into drying box to be put into roaster after when dry 2-3 is small at 100-105 DEG C, is being filled
Under the oxygen atmosphere of foot, pre-burning 40-60 minutes is carried out to be heated to 400-500 DEG C under anthracitic combustion, is continued with one
Fixed heating rate is continuously heating to 1080-1180 DEG C, roasts 50-60 minutes, cooled to room temperature after the completion of sintering, powder
It is broken, 200 mesh sieves are crossed, obtain burning till plating slag mud powder；
（3）By cement, lime, gypsum, flyash, burn till plating slag mud powder, polypropylene fibre is added to according to a certain percentage
In agitated kettle, dry mixed adds waterglass, the triethanolamine of 0.3-0.4 ‰ of mixture quality 0.1-0.12% after 4-5 minutes
And suitable water, certain ratio of water to material is controlled, is quickly stirred 1-2 minutes with 800-1000 revs/min of speed and obtains slurry；
（4）Foam stabilizer is dissolved in the 5-6 times of deionized water measured, then adds aluminium powder, is mixing uniformly to form aluminium powder suspension
Liquid, is rapidly joined step afterwards（2）In slurry, stirring is poured into mould after 40-60 seconds, in 60-65 DEG C of steam curing box
In it is quiet stop 4-5 it is small when after cut off crust and form removal, finally by air-entrained concrete building block in relative humidity 80%, thermostat temperature 80
Continue to be put into standard curing room maintenance 28 days after when maintenance 5-6 is small under the conditions of DEG C.
