Description

The method that absorbent-type medical stone kaolin clay microballon prepares the porous sponge brick that catchments
Technical field
The present invention relates to the method that absorbent-type medical stone kaolin clay microballon prepares the porous sponge brick that catchments, belong to material Technology is led.
Background technology
Due to EI Nino and La Nina Phenomenon, there is extreme change in the weather in China, and rainfall distributed pole is uneven, south Northern drought and waterlogging are uneven, and rainfall is also extremely unequal in same area, 1 year, and water shortage has restricted expanding economy and the people Life, rationally using existing precipitation, by cell road surface, road, the effective precipitation in public leisure square rationally collect, store, Utilize, alleviate drought and water shortage season use water, the thermal capacity of water is big, can absorb heat also can heat release, improve miniclimate.
The content of the invention
There is well plastic by the use of the hollow clay microballon of medical stone kaolin perforate of perforate as base-material, kaolin Property, the smaller specific surface area of medical stone particle diameter is bigger, and adsorption capacity is stronger, and medical stone is to heavy metal ion adsorbed in water, essence On be that heavy metal cation in cation and water in medical stone swaps, adsorbed by ion exchange medical stone in water Heavy metal cation, adjust the pH value of water, using sodium metasilicate as binding agent, cement is strong for the porous sponge brick increase machinery that catchments The resin fibre of degree and cementation, flyash and polyvinyl alcohol high water absorption is strong water absorbent, using dilatant slurry, reduces slurries Density, a face of the manufactured porous sponge brick that catchments is in dovetail channel-shaped, it is porous catchment sponge brick absorption moisture enter swallow Stern notch, collector pipe is flowed into again by the effect of gravity, collector pipe links together the porous sponge brick that catchments, and rainwater catchment is to catchmenting Chi Zhong.
Its technical scheme is:The method that absorbent-type medical stone kaolin clay microballon prepares the porous sponge brick that catchments, first Step, the dispensing of the porous sponge brick that catchments:15~20wt% of cement, particle diameter are 100~250 μm of hollow potteries of medical stone kaolin perforate Native 50~75wt% of microballon, 5~15wt% of sodium metasilicate of modulus 3.2~3.5,5~10wt% of flyash of loss on ignition 1.1%, poly- second Enol high hydroscopic resin 0.5~3.0wt% of fiber, the percentage by weight sum of above each component is 100%;
The preparation of second step, the porous sponge brick expansion water suction slurries that catchment:Sample by the percentage by weight of the first step, first will Particle diameter is that 100~250 μm of hollow clay microballons of medical stone kaolin perforate are put into feed bin, and distributing device, cloth are sent into by elevator The hollow clay microballon of medical stone kaolin perforate is evenly distributed on governing belt balance by glassware, and spray thrower is by modulus 3.2~3.5 Sodium metasilicate be uniformly sprayed at the outer surface of the hollow clay microballon of medical stone kaolin perforate, the hollow pottery of medical stone kaolin perforate Native microballon enters inside spin drum agitation device with governing belt balance, makes the outer of the hollow clay microballon of each medical stone kaolin perforate Sodium metasilicate is all uniformly adhered on surface, and sodium metasilicate is inorganic bond, is hydrophilic, and cohesive force is strong, intensity is higher, acid resistance, Heat-resist, hydrophilicity does not influence caking property, and compound is 15~20wt% of cement, particle diameter is 100~250 μm of medical stone height 50~75wt% of the hollow clay microballon of ridge soil perforate, 5~15wt% of sodium metasilicate of modulus 3.2~3.5, the fine coal of loss on ignition 1.1% 5~10wt% of ash, polyvinyl alcohol high hydroscopic resin 0.5~3.0wt% of fiber, then compound is adjusted with 0.5~0.7 ratio of mud Slurry, ash is compound, is eventually adding the aluminium powder cream that compound gross weight is 0.2~1.0%, hydration reaction generation bubble, is formed more The slurries of hole expansion water suction, reduce the weight of sponge brick, and polyvinyl alcohol high hydroscopic resin fiber has extremely strong water imbibition, absorbed water Sponge brick compression strength afterwards is constant;
The preparation of the porous sponge brick that catchments of 3rd step, absorbent-type:Expansion water suction slurries prepared by second step stir Pour into the die trial of sponge brick press, by 1.2~2.0:1 volume ratio is suppressed, and ratio 1.2~2.0 is the volume before compacting, than Example 1 is the volume after compacting, through striking off, suppressing, being stripped, drying, is made the porous sponge brick that catchments, porous to catchment the one of sponge brick Individual face is in dovetail channel-shaped, and the porous moisture for catchmenting the absorption of sponge brick enters in dovetail groove, in collector pipe insertion dovetail groove, collector pipe A part of arc surface in embedded dovetail groove is openning shape, and another part arc surface is closed, and rainwater passes through porous sea of catchmenting Continuous brick collects, and into dovetail groove, is flowed into collector pipe again by the effect of gravity, collector pipe connects the single porous sponge brick that catchments It is connected together, the rainwater that collector pipe collects enters in collecting-tank.
The preparation of the hollow clay microballon of medical stone kaolin perforate:First by 80~200 μm of medical stones of particle diameter, 200~400 μm Kaolin is by weight 20~30:70~85 compounds stir, and the percentage by weight sum of two kinds of components is 100%, mixing Material is sized mixing by 0.5~0.7 ratio of mud, the compound that ash forms for two kinds of compositions of medical stone and kaolin, by centrifugal rotation Injection forms microballon at a high speed, then through 800~950 DEG C of expansions, 1000~1500 DEG C of firings, quick cooling, forms wall thickness 50~100 μm, particle diameter is 100~250 μm of medical stone kaolin perforate cenosphere, and kaolin has good plasticity and ductility, By high-temperature firing, the modified hollow clay resistance to compression microballon of the compound perforate of medical stone kaolin is formd, the component of material is different, The chemical property of modified material is also different, and the smaller specific surface area of medical stone particle diameter is bigger, and adsorption capacity is stronger, and medical stone is to water In it is heavy metal ion adsorbed, the heavy metal cation in cation and water substantially in medical stone swaps, pass through Ion exchange medical stone has adsorbed the heavy metal cation in water, adjusts the pH value of water.
The modulus of sodium metasilicate is most important, and when modulus is more than 3.5, with the increase of modulus, sodium metasilicate, which is hardened, to become fragile, and glues Knot property is deteriorated, and when modulus is less than 3.2, caking property declines.
Flyash is strong water absorbent, by high temperature sintering, there is higher activity.
A rainwater part for accumulation is pooled in collecting-tank by the porous sponge brick that catchments by collector pipe, and another part penetrates into Into soil, increase soil water content, in summer high-temperature season, the heat on surface can also be transmitted to by the porous sponge brick that catchments In soil, the temperature on sponge tile floor surface is reduced, the thermal capacity of water is big, and can absorb heat also can heat release.
The present invention has advantages below.
1st, the Materials Inorganic environment-friendly materials used in sponge brick are prepared, environment will not be damaged, the recyclable energy of sponge brick Secondary use.
2nd, it is strong water absorbent to prepare sponge brick flyash and the resin fibre of polyvinyl alcohol high water absorption, can absorb sponge brick table The moisture in face enters inside, when reaching certain amount, is dropped into the presence of by gravity in collector pipe.
3rd, aluminium powder cream is added in compound, forms the slurries of porous expansion, reduces the density of slurries.
4th, the heavy metal cation in the cation and water in medical stone swaps, and is adsorbed by ion exchange medical stone Heavy metal cation in water, adjust the pH value of water.
