Abstract
The present invention discloses a brick making method by using basalt instead of clay, which is characterized in that the brick is made from the following raw materials of the weight percentage: 35 to 65% of basalt, 25 to 45% of flyash, 5 to 15% of coal gangue and 2 to 8% of straw; the brick is made by the following processing steps: (1) breaking and grinding the raw materials into powder; (2) evenly blending the raw materials to be made into pug with water; (3) making the pug into green bricks; baking the green bricks or drying the green bricks in the sun; putting the dried green bricks into a kiln and calcining the green bricks in an external combustion and internal combustion combined mode by using the combustibility of the raw materials of the flyash, the coal gangue and the straw; (6) cooling the green bricks to obtain the finished products of the bricks. The brick making method by using basalt instead of clay not only can save a large number of cultivated land resources, but also can obtain quality building bricks with high strength and high quality.
Description
Technical field
The present invention relates to a kind of brick-making method of building brick, be specifically related to a kind of brick-making method with the basalt instead of clay.
Background technology
Rapid development of economy makes the demand of building brick be doubled and redoubled, and especially a large amount of projects of tearing down and building makes that the demand of building brick is increasing in the city.And present building brick nearly all is to adopt clay to fire to form, and needs a large amount of diggings to plough, and causes a large amount of cultivated land resource losses and waste.Country has adopted measure at present, and restriction is protected rare cultivated land resource with clay-brickmaking.For this reason, many in recent years production firms and scientific and technical personnel are in exploitation new building brick product and the technology of concentrating on studies, to substitute traditional clay-brickmaking.By retrieval, it is 98113840.3 that Chinese patent has been announced a patent No. on February 20th, 2002, and name is called the patent of invention of " baking-free brick made with basalt ".It is raw material with basalt, cement, slag, boron mud, useless lime that this patent has proposed a kind of, the baking-free brick made with basalt that adopts the press type method to produce.This scheme is being brought into play positive role aspect the cultivated land resource saving, but because what adopt is that the physical technology of non-sintering is carried out brickmaking, the intensity of its finished bricks and quality still remain further to be improved.
Summary of the invention
The object of the invention provides a kind of brick-making method with the basalt instead of clay, and this method can be saved a large amount of cultivated land resources, can obtain high strength, high-quality high-quality building brick again.
For achieving the above object, the technical solution used in the present invention is: a kind of brick-making method with the basalt instead of clay, produce by following raw material proportioning and processing step:
(1), raw material and percentage by weight:
Basalt 35~65%;
Flyash 25~45%;
Gangue 5~15%;
Stalk 2~8%;
(2), processing step:
1., raw material smashed clays into power, smashing fineness is below the 3mm;
2., material powder is mixed, add water and make pug, carry out ageing then and handle, its time is 48~96 hours;
3., pug made adobe adopt vacuum extruder, its vacuum≤-0.092Mpa;
4., with brick blank drying or dry;
5., kiln is put in dry adobe, the method for utilizing the combustibility of raw meal coal ash, gangue, stalk to adopt external combustion and internal combustion to combine is carried out roasting, and sintering temperature is 950~1150 ℃;
6., after cool off finished product.
Related content and change interpretation in the technique scheme are as follows:
1, in the such scheme, the relatively good scope of the weight percent of raw material is:
Basalt 40~60%;
Flyash 28~42%;
Gangue 7~13%;
Stalk 3~7%.
2, the percentage by weight optimum range about raw material is:
Basalt 45~55%;
Flyash 32~38%;
Gangue 8~12%;
Stalk 4~5%.
Operating principle of the present invention is: in composition of raw materials, primary raw material substitutes original clay with basalt, and other raw material is respectively flammable flyash, gangue and stalk.In brickkiln in the roasting process, brick external body environment temperature is mainly provided by fuel such as fire coals, but because flyash, gangue and stalk are combustible, the combustible of mixing in the brick body during roasting provides calorific value simultaneously, and its internal combustion roasting order is: stalk → gangue → flyash.Such internal combustion roasting and external combustion roasting cooperatively interact, and can obtain high strength, high-quality high-quality building brick under the chemical reaction effect.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1, because primary raw material of the present invention adopts basalt to substitute original clay, can save a large amount of arable lands, effectively protect cultivated land resource.
2, because basalt when being volcano eruption, underground magma be sprayed onto meet in the air cold and form have certain chemically active poroid, a lightweight rock, claim float stone again.Adopt basalt to have advantages such as insulation, sound insulation, light weight, high-strength, good toughness, water absorption rate are low, non-efflorescing cementitious as the main material of building brick.Especially be fit to production high-quality, high-strength building brick.Through experiment test only the compressive strength rate common building improve 20~40% with brick.
3, the present invention is in roasting process, owing to adopt internal combustion and external combustion process combined method, the chemical reaction of producing during to burning is very favourable, has further improved product quality.
4, the present invention has reduced hear rate to greatest extent owing to adopt the UTILIZATION OF VESIDUAL HEAT IN of " internal combustion roasting method " and annular kiln, has improved the thermal efficiency.
Description of drawings
Accompanying drawing 1 is an embodiment of the invention process chart.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
