Abstract
The invention relates to a manufacturing method of a large-aperture honeycomb building block, and belongs to the technical field of artificial stone in chemistry. The manufacturing method of the building block comprises the following steps that (1) materials are prepared; (2) the raw materials are fed into a planetary stirring machine to be stirred for 5 to 7 minutes; (3) the raw materials subjected to material mixing are injected into a mold die cavity defined by left and right die molds; (4) the pressure is applied to mixed materials in the mold die cavity by a hydraulic machine at the hydraulic pressure of 150 to 250kg/cm<2>, so that the raw materials in the mold die cavity are pressurized and compactly formed; and then, the left and right die molds are fixed into a whole; and (5) the left and right die molds fixed into a whole and the building block formed after pressure application are put into a constant temperature and constant humidity box for maintenance under the maintenance conditions of the humidity being 90 to 100 percent and the temperature being 20+/-2 DEG C; the mold is removed after the maintenance is performed for 8 hours; after the demolding, the building block is continuously maintained in the maintenance box; and the finished product is obtained after the set period is reached. The manufacturing method of the building block has the advantage that polystyrene particles and sludge generated by domestic sewage plants can be used for manufacturing the light-weight building block without secondary pollution.
Description
Technical field
The present invention relates to a kind of large aperture honeycomb building block manufacture method, belongs to artificial stone technical field in chemistry.
Background technology
A large amount of sanitary sewage disposals are filled out in current city --- precipitating sludge Jing after pressure, filter predrainage moisture content still 60-85% it
Between（Containing the crystallization water）Sludge silt because wherein containing the harmful substance such as heavy metal, various places government forbids to fill on the spot, though it is useful
Chemical method dehydration fed to boiler is burned or disposed by cement plant, but its amount of clearing up is far from meeting yield.
It is the also difficult crystalloid water for evaporating of exposure in the sun to be full of big portion in 80% moisture content in domestic sewage factory sludge
Body, even if be exposed to the sun can only also dissipate a small amount of crystalloid water body, and is up to 80% town domestic sewage factory sludge to moisture content
To reduce its moisture content（Even if by 80% to 60% moisture content）, the input of its required energy and fund seriously loses more than gain,
And secondary pollution is also extremely difficult avoids.Therefore, disposal and the recycling of reasonable environmental protection how are carried out to sludge, is individual very big
Problem.
Meanwhile, according to the applicant understood, modified styrene polymer is widely used, and has brought many convenience, but due to
Waste polystyrene is difficult to compress and degrades, and the environmental pollution that causes to used foamed plastics of people lacks and enough recognizes
Know, used used foamed plastics product arbitrarily abandoned, polystyrene has the characteristic such as ageing-resistant, difficult degradation, anticorrosive again,
Serious harm is caused to environment, also becomes a great problem of garbage disposal.
The content of the invention
The technical problem to be solved in the present invention is not enough for prior art, proposes that a kind of comprehensive utilization domestic sewage factory is produced
Raw sludge and waste polystyrene are producing the light-duty large aperture honeycomb building block manufacture method of non-secondary pollution.
The present invention is that the technical scheme for solving above-mentioned technical problem proposition is：A kind of large aperture honeycomb building block manufacture method,
It is characterized in that：Comprise the following steps：
1）Following components raw material is selected by mass：Component one：Sludge and dry coal that the domestic sewage factory of aqueous 60%-80% is produced
Lime-ash half-and-half blends the compound after stirring：36-60 parts；Component two：It is broken into the dry building waste bits powder of below 15mm：
30-60 parts；Component three：Cement：25-36 parts；Component four：Polystyrene ball particle 0.7-1.1 parts of 1.0-1.2mm particle diameters；
2）By above-mentioned raw materials input planetary stirring machine stirring 5-7 minutes；
3）Raw material after batch mixing is injected in the mold cavity surrounded by left right model mould；
4）By hydraulic press the compound in mold cavity is pressed with the hydraulic coupling of 150-250kg/cm2, in making mold cavity
Raw material pressurization and densification shaping, are then integrally fixed on left right model mould；
5）The left right model mould being integrally fixed and the building block after pressing formation are placed in climatic chamber and are conserved, curing condition
For humidity：90-100%, temperature is 20 ± 2 DEG C, and maintenance removes mould in 8 hours, and building block after the demoulding continues to be conserved in curing box,
Get product to setting age.
The working mechanism and beneficial effect of large aperture honeycomb building block manufacture method technical scheme disclosed in the invention described above is old
State as follows：
1）The sludge and dry coal lime-ash produced by the domestic sewage factory by the aqueous 60%-80% of 36-60 parts half-and-half blends stirring
Afterwards, with the 1.0- of dry building waste bits powder, the cement of 25-36 parts and 0.7-1.1 parts for being broken into below 15mm of 30-60 parts
The polystyrene ball particle of 1.2mm particle diameters carries out dispensing, by hydraulic press with the hydraulic coupling of 150-250kg/cm2 by mould
Compound densification shaping in die cavity, makes to combine densification between brick body material granule, has concurrently during sludge crystallization water participation hydrated cementitious wet
The profit effect of watering；Easily incorporated and perpendicular solid cement products is formed after fully wrapped around other material of cement, make to be diluted to dry powder
Material counts micro heavy class nuisance and polystyrene ball particle contained by the sludge powder for only accounting for 9% or so and is blocked and be difficult to analyse
In the Behavior of Hardened Cement Paste of solution, it is possible to use it is relatively light while and not causing secondary to environment that sludge and polystyrene produce building block overall weight
Pollution；2）The processing method of this solidification, is not only able to the annual produced dredging silt of a large amount of process and waste plastic foam,
And and substantially reduce the permeability of solidified after-product, while avoid that pernicious gas is produced because of air storage, greatly
The environmental pollution that both discarded objects bring is eliminated, very big social benefit is produced.
The change of above-mentioned technical proposal is：In the step 1）In, also constitute including following components by mass:Plastics
Or steel fibre：0-7 parts.
There is steel fibre due to referring and synthesizing, the high-quality product of high intensity mixing of steel fiber can be made.
The change of above-mentioned technical proposal is：In the step 4）The compacting rate of the densification shaping of compound in middle mold cavity
It is for 1.4-1.6：1.
