Abstract
The high strength fly ash haydite producing process belongs to the field of fly ash utilizing and new building material technology. The high strength fly ash haydite is produced with fly ash, clay, saw dust and coal powder, and through mixing in a stirrer, adding certain amount of water glass and controlling water content of about 20 %, pelletizing, sintering and cooling. The high strength fly ash haydite product has granularity of 3-5mm, bulk density of 800-900kg/cu m, and compression strength of 10-20 MPa, and may be used as aggregate of wall board.
Description
Technical field
The invention belongs to utilization of fly ash and building material industrial technology field, particularly a kind of manufacture method of high strenght flyash ceramic sand.
Background technology
Flyash is the waste of heat power plant, and discharge capacity is very big, if handle badly, can bring very big harm to environment.At present, also do not have to produce specially the technology and the equipment of flyash ceramic sand, existing flyash ceramic sand all screens, and limited amount, and shape irregularity substitute the granule sandstone fully and also have certain difficulty very much.Thus, the invention of flyash ceramic sand is imperative.
Summary of the invention
Technical problem to be solved by this invention is: develop a kind of small, evengranular flyash ceramic sand, have the building material aglite of lightweight, high-strength, insulation and fire-resistant characteristics.
Making method of the present invention is as follows:
With flyash, clay, fine sawdust, coal dust, water glass batching, its cooperation ratio is as follows by weight:
Flyash: 75%～80%
Clay: 12%～20%
Fine sawdust: 2%～5%
Coal dust or flue dust 3%～7%
Water glass: 0.5%～2%
Wherein used flyash is the fines of collecting in the boiler of power plant flue gas; Used clay is for pulverizing the back granularity less than 40 purpose clay powders; Fine saw art and coal dust (or flue dust) are less than 40 purpose powder.
Blending process
1) after scope took by weighing according to the above ratio with flyash, clay, fine sawdust, coal dust, putting together mixed;
2) water glass is made into 0.02%～0.03% the aqueous solution;
3) spray into a certain amount of aqueous solution for preparing, mix material, the control water ratio is between 15%～25%;
4) material that stirs being put into the flat-die nodulizer granulates;
5) made grain is put into the disk balling machine balling-up;
6) ball that is become is put into the sintering oven roasting, when the control sintering temperature reaches between 900 ℃～950 ℃, be incubated 20～30 minutes, continue then to give birth to temperature, when reaching 1200 ℃～1300 ℃, be incubated 30～60 minutes, sintering finishes;
7) after sintering finished, kiln internal cooling to 550 ℃～600 ℃, the kiln discharge naturally cooling was finished.
Preparation process is:
Get material → batch mixing → and material → granulation → moulding → sintering
Equipment used is all prior art in the above manufacture method, and raw materials used all being very easy to obtains.
The invention has the beneficial effects as follows: the flyash ceramic sand of producing has lightweight, high-strength, insulation and advantage such as fire-resistant, to a certain extent, alternative generation the granule sandstone, and surface attachment layer oxide film, water-intake rate is very low, add it and can improve the water resistance of material, weight reduction, improve the density uniformity of material, combine with heat pressing process, can improve the workability of material greatly, used the wallboard of this pottery sand, block, cutting edge or boring, ailing all be very easy to, and be and very reliable.The product grade is 3mm～5mm, and particle is regular, the uniformity coefficient height, and its packing density of particle is generally at 800kg/m
3～900kg/m
3, apparent density is 1000kg/m
3～1100kg/m
3, cylindrical compress strength is 10Mpa～20Mpa.
