Embodiment
, below will be in the embodiment of the present invention to make the purpose, technical scheme and advantage of the embodiment of the present invention clearer
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, according to normal condition or manufacturer
It is recommended that condition carry out.Reagents or instruments used without specified manufacturer, is the routine that can be obtained by commercially available purchase
Product.
The light cellular partition board and its manufacture craft of the embodiment of the present invention are specifically described below.
A kind of light cellular partition board provided by the invention, it is counted including following raw material by ratio of weight and the number of copies：Cement 20~28
Part, 12~20 parts of flyash, 2~6 parts of gypsum, 40~48 parts of grain slag, 7~15 parts of water, 1~3 part of water-reducing agent and air entraining agent
0.001~0.005 part.
Grain slag, i.e. blast-furnace cinder, are the water quenching waste residues discharged in blast furnace ironmaking production process, are that China is main at this stage
Melting waste slag.Chemically component is seen, it is mainly SiO2, Al2O3 and Ca O, belongs to phyllosilicate material.Often produce the pig iron
The discharge capacity of blast furnace slag changes with the difference of the grade of ore and smelting process during 1t, and the pig iron per ton produces 0.3~1.2t
Blast furnace slag.With the development of China's steel and iron industry, the discharge capacity of blast furnace slag increasingly increases.In some embodiments of the present invention
In, the particle diameter of grain slag is not more than 5mm, and grain slag powder within the range, which is spiked into, makes the performance of cement more superior in cement.
Flyash, is the fine ash that catching is got off from the flue gas after coal combustion, is that the primary solids of coal-burning power plant's discharge give up
Thing.The main oxides of power plants flyash form：SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 etc..With electricity
Power industrial expansion, the flyash discharge capacity of coal-burning power plant increase year by year, become the larger industrial residue of the current discharge capacity in China it
One.Substantial amounts of flyash is untreated, will produce airborne dust, pollutes air；River can be caused to silt up if being discharged into water system, and its
In toxic chemical substance can also damage to human body and biology.Flyash resourcebility is utilized, as mixing for concrete
Material is closed, can effectively alleviate environmental pressure, environmental protection and energy saving.
Water-reducing agent, is a kind of under conditions of maintaining concrete slump to be basically unchanged, can reduce the mixed of mixing water amount
Solidifying soil additive.Belong to anion surfactant mostly, there is lignosulfonates, naphthalene sulphonate formaldehyde polymer etc..Add
There is peptizaiton to cement granules after concrete mix, its workability can be improved, reduce unit consumption of water, improve concrete
The mobility of mixture；Or unit cement consumption is reduced, save cement.
Air entraining agent, to improve the workability of concrete mix, water-retaining property and cohesiveness, improves concrete flowability,
A large amount of equally distributed, closure and the additive of micro-bubble stablized are introduced during the mixing and stirring of concrete mix.
A kind of preparation process according to light cellular partition board provided by the invention, it includes：By 20~28 parts of cement, fine coal
1~3 part of 12~20 parts of ash, 7~15 parts of water and water-reducing agent are mixed into the first slurry, and air entraining agent is added in the first slurry
0.001~0.005 part, 2~6 parts of stirrings of 40~48 parts of grain slag and gypsum obtain the second slurry, by the second slurry pouring molding,
Steam curing, then draws finished product.
Further, in some embodiments of the invention, after obtaining the first slurry, air entraining agent mixing, bleed are first added
Agent can fully introduce uniform bubble, the density of the first slurry and/or the second slurry is kept within the specific limits, be to protect
Demonstrate,prove the essential condition of wallboard lightweight.Preferably, the mixing time after the first slurry addition air entraining agent is 3~5 minutes, the stirring
Time is too short to cause that bubble is insufficient, and overlong time, bubble is easily broken, so that cause last small product size to diminish,
Weight increase.
Further, in some embodiments of the invention, the mixing time of the second slurry is 2~5 minutes, the second slurry
Mixing time after material, i.e. addition grain slag and gypsum is 2~5 minutes, and the mixing time is too short to cause mixing uneven,
Overlong time is easy to cause drum rupture.
Further, in some embodiments of the invention, by the second slurry pouring molding, 30 are rested after pouring molding,
Minute, make cementitious material final set, prevent from causing to destroy internal structure when steam curing.
Further, in some embodiments of the invention, when the above-mentioned steam-cured time is 4~6 small, steam is supported
The temperature of shield is 60 °~80 °, and heating duration is preferably grown should not be short, and rising sharply and die-offing for temperature can all cause material internal structure
Stress variation destroys structure.
The feature of the present invention is described in further detail with reference to embodiments.
