Abstract
The invention relates to a hollow thermal-insulation block as well as the manufacturing method thereof, the main raw materials of the block comprise light burned magnesium powder, magnesium chloride solution, mineral materials derived from municipal refuses, agricultural wastes, fly ash and hydrochloric acid, and the mixture ratio is as follows: 200 parts of the light burned magnesium powder, 40 to 75 parts of the magnesium chloride solution at 28 to 32 DEG, 1 to 2 parts of the industrial hydrochloric acid with the content of 36 to 38 percent, 80 to 120 parts of the mineral materials derived from the municipal refuse, 20 to 30 parts of the agricultural waste, and 50 to 80 parts of the fly ash. The manufacturing comprises the following steps: preparing the raw materials, preparing the slurry, casting and natural curing. The method can adopt a large quantity of mineral materials derived from the municipal refuse and the agricultural waste, thereby realizing the recycling of the waste materials, facilitating the mineral resource conservation and the environmental protection.
Description
Technical field
The present invention relates to a kind of building block, its part material derives from municipal wastes and agricultural wastes, has realized the recycling of refuse, belongs to building material field and field of environment protection.
Background technology
The manufacturing of material of construction at present consumes Mineral resources in large quantities, for saving Mineral resources, people begin constantly demand in the mode that recycles of waste, wherein widely used is utilization of coal ash, owing to contain certain activeconstituents in the flyash, it is added in the grout not only can plays certain filling effect, save the cement consumption, and product performance is improved, because the development of these technology, flyash also changes a kind of useful material that can sell into by a kind of waste of payment processes expense that needs.
But, the recycle mode that does not then still find for municipal wastes and agricultural wastes, except the material that can directly recycle was on a small quantity recycled, remaining most of material all was to adopt the mode of landfill and burning to handle in the present municipal wastes.These treatment technologies all have very important defective, for example landfill needs occupied ground, and can bring pollution to underground water body and air, burning then needs consumes energy, and also contain obnoxious flavour and suspended particulate in its flue gas, the difficulty of administering is also very big, and agricultural wastes except some areas as the fuel, the value of its utilization and utilize degree all little.
Municipal wastes comprises multiple composition, comprise plastics, paper, cloth, fresh and dried plant, wooden unit, glass, pottery and sandstone dust or the like, a kind of feasible processing mode is that municipal wastes is carried out sorting, carry out different processing according to the different material that sorts out, particularly resembling the material that iron, plastics, fiber etc. can act on industrial raw material progressively obtains reclaiming and utilizing, remaining most of material is except clay, basically all be bulk or the granular mineral material that constitutes with oxide compound and inorganic salt, these compositions are not effectively utilized at present.And the biological degradation in the process of the organism wherein methane-generating pit, the methane-sludge of formation also needs one and finally utilizes mode.
Summary of the invention
For overcoming the defective of prior art; the invention provides the manufacture method of a kind of hollow heat-insulation building block and this building block; this building block can be a large amount of the employing municipal wastes in mineral materials and agriculture waste material powder; realized the recycling of these waste materials; help saving mineral wealth, help environment protection.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of hollow heat-insulation building block, its raw material comprises methane-sludge, clay, flyash, come from the Mineral feedstock of municipal wastes and come from the biomass material flyash of agricultural wastes, various raw material relative weight ratios are: methane-sludge 60-80 weight part, clay 40-60 weight part, flyash 30-40 weight part, come from municipal wastes Mineral feedstock 20-35 weight part, come from the biomass material 60-80 weight part of agricultural wastes.
A kind of preparation method of environment-friendly light brick comprises the following steps:
(1) gets the raw materials ready, choose various materials, pulverize and sieve;
(2) batching and stirring take by weighing various raw materials according to above-mentioned relative weight ratio, add water and stir in the pair roller stirrer, and water content is advisable with 25-28% in the wet feed of formation;
(3) ageing entered the ageing of ageing storehouse 36-72 hour;
(4) extrusion molding of agent brick machine is adopted in compression moulding;
(5) airing, to water content be 10-11%;
(6) sintering temperature should be controlled at 1060-1100 ℃;
(7) cooling, naturally cooling.
The present invention has effectively utilized city garbage specification to handle the Mineral feedstock that the back forms, come from the methane-sludge that the biomass material of agricultural wastes and biogas form in handling, realized the final recycling of these materials, eliminated to handling the soil that these materials take or the energy of consumption, and part has substituted existing raw mineral materials, realized the recycle of physical resources, reduced destruction to physical environment and natural resources, help the Sustainable development of economic society, combustiblesubstance spontaneous combustion in sintering process in the raw material, help improving the internal structure of building block, form hollow heat-insulation building block.
