Abstract
The present invention relates to a method for manufacturing the building material with the urban garbage, the urban building material is done with primary crushing and sorting to sort the fiber material and the mineral material, the fiber material is secondary-crushed to short thread and the mineral material is secondary-crushed to fine particle, fiber material 5-10 parts (weight part, the following are same), mineral material 40-60 parts, low-water cement 20-30 parts, other material 0-30 parts and appropriate water are taken, the fiber material, mineral material and other material are mixed to uniform, then the low-water cement is added and mixed to uniform, the water is added and stirred to slurry, the mixture is placed into the mold for vibration molding or extrusion molding, and forming the building sheet material product after natural curing. The method of the invention can use part component of the urban pollutant, the material resource is saved and the final discharge amount of the urban pollutant is reduced, and the method can be used for preparing building materials of hollow brick, hollow block, partition plate and the like.
Description
Technical field
The present invention relates to adopt municipal wastes to make the method for building materials, belong to environment protection and building material field.
Background technology
Municipal wastes comprises multiple composition, comprise plastics, paper, cloth, fresh and dried plant, wooden unit, glass, pottery and sandstone dust or the like, intractability is big, at present except the material that wherein can directly recycle is on a small quantity recycled, other major parts all adopt the mode of landfill and burning to handle, but 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 improvement is also very big.Therefore people begin to attempt gradually municipal wastes is carried out sorting, carry out different processing according to the different material that sorts out then, particularly resemble the material that iron, plastics, fiber etc. can act on industrial raw material and progressively obtain reclaiming and utilizing.But the most of material in the municipal wastes is not still effectively utilized at present.
Summary of the invention
Be to enlarge the material scope of recycling in the municipal wastes, the method that provides partial material in a kind of building waste to be used to make material of construction of the present invention adopts this method the part in the municipal wastes can be converted to useful product.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of method that adopts municipal wastes to make building materials, it carries out primary fragmentation and sorting to the urban architecture material, sub-elect fibre material and mineral materials, the fibre material secondary breaking is become short silk, the mineral materials secondary breaking is become fine particle, get fibre material 5-10 part (mass parts, down together), mineral materials 40-60 part, low-water cement 20-30 part, unclassified stores 0-30 part, water is an amount of, with fibre material, mineral materials and unclassified stores mix, and add low-water cement again and mix, and add water and stir pulping, insert vibratory compaction or extrusion forming in the mould, form the building slab section product after the natural curing.
Because it is bigger to come from the material proportion of municipal wastes in the raw material of the present invention, can reduce resource consumption in a large number, reduce the final quantity discharged of municipal wastes, turn waste into wealth; Because adopt low-water cement as jointing material, its cohesive force is strong, the consumption of cement is few, the quality product height, and the holllow building block ultimate compression strength of making as required, can be made hollow brick, holllow building block and partition plate etc. more than 7.5MPa.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Referring to Fig. 1, the invention provides a kind of method that adopts municipal wastes to make building materials, it carries out primary fragmentation and sorting to the urban architecture material, sub-elect fibre material and mineral materials, the fibre material secondary breaking is become short silk, the mineral materials secondary breaking is become fine particle, get fibre material 5-10 part (mass parts, down together), mineral materials 40-60 part, low-water cement 20-30 part, unclassified stores 0-30 part, water is an amount of, with fibre material, mineral materials and unclassified stores mix, adding low-water cement again mixes, add water and stir pulping, insert vibratory compaction or extrusion forming in the mould, form the building slab section product after the natural curing.
Described primary fragmentation can adopt jaw crusher, this crusher in crushing is more even than the raw meal particle size after big, simple in structure, the fragmentation, and simple in structure, the working cost and the maintenance cost of equipment itself are relatively large, are suitable for the material fragmentation of this composition of municipal wastes and character complexity.
Can two steps will be divided in the primary fragmentation in case of necessity, the first step adopts above-mentioned jaw crusher fragmentation, bulk crushing is become fritter, second step was adopted impact crusher and/or roll crushing crusher machine, wherein impact crusher is suitable for hard in the fragmentation, soft, crisp, toughness, fibering material, and roller crusher is suitable in the material that hardness is bigger broken and in small, broken bits.The selection of these disintegrating apparatus can be determined according to the specific nature of rubbish.
Described sorting can be multipass sort, adopt pneumatic separating or air jigging that rubbish material is divided into heavy material and light material earlier, again heavy material is carried out the sorting of secondary jigging and mineral materials is isolated in magnetic separation, light material is carried out the sorting of secondary air jigging isolate fibre material.
The secondary breaking of described mineral materials can be adopted roller crusher or ball mill.
The secondary breaking of described fibre material can be adopted roller crusher, impact crusher or shear crusher.
Described low-water cement can adopt the 425# low-water cement.
Described unclassified stores can comprise flyash, under the situation of above-mentioned material proportion, the addition of described flyash can be 0-30 part, because flyash has certain hydraulicity and binding property, not only play filling effect, and with respect to the mineral materials that comes from municipal wastes, it also has certain effect to intensity.
Described unclassified stores can also adopt various other mineral particles such as metallurgical tailings sand.
Described unclassified stores can also comprise hardening accelerator and/or water reducer, add hardening accelerator and help the demoulding early, enhance productivity, add water reducer and help reducing water consumption, improve degree of compactness and intensity, the composition of hardening accelerator and water reducer and consumption can be selected for use according to the testing data and the description of use of various hardening accelerator and water reducer according to prior art.
Below, provide the embodiment of several material proportions, unlisted hardening accelerator and water reducer in these prescriptions, the user can be according to actual needs and the prior art that relates to hardening accelerator and water reducer freely select for use.
