Description

The method that heat-conducting type zeolitic silica ceramic fine bead prepares the porous sponge brick that catchments
Technical field
The present invention relates to the method that heat-conducting type zeolitic silica ceramic fine bead 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 the water of using in drought and water shortage season, it is significant.
The content of the invention
For zeolitic silica cenosphere as base-material, silica has a strong crushing resistance, and chemical property is stable, not with Water reacts, and the smaller specific surface area of sized zeolite particles is bigger, and adsorption capacity is stronger, and zeolite can adsorb ammoniacal nitrogen in water, have Machine thing and heavy metal ion, the performance also with ion exchange and acidproof heat-proof, the pH value of water is adjusted, can be by sponge brick table Face is thermally conducted in soil, and using sodium metasilicate as binding agent, cement increases mechanical strength and bonding for the porous sponge brick that catchments Effect, the resin fibre of flyash and polyvinyl alcohol high water absorption is strong water absorbent, using dilatant slurry, reduces the density of slurries, One face of the manufactured porous sponge brick that catchments is in dovetail channel-shaped, and the porous moisture for catchmenting the absorption of sponge brick enters dovetail groove, by The effect of gravity flows into collector pipe again, and collector pipe links together the porous sponge brick that catchments, and rainwater catchment is into collecting-tank.
Its technical scheme is:The method that heat-conducting type zeolitic silica ceramic fine bead 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 zeolitic silica perforate 60~75wt% of porcelain microballon, 5~15wt% of sodium metasilicate of modulus 3.2~3.5,3~10wt% of flyash of loss on ignition 1.1% and poly- Vinyl alcohol high hydroscopic resin 0.5~2.0wt% 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 zeolitic silica perforate hollow ceramic microspheres are put into feed bin, and distributing device, cloth are sent into by elevator Zeolitic silica perforate hollow ceramic microspheres are 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 surfaces of zeolitic silica perforate hollow ceramic microspheres, the hollow pottery of zeolitic silica perforate Porcelain microballon enters in inside spin drum agitation device with governing belt balance, makes each zeolitic silica perforate hollow ceramic microspheres Sodium metasilicate is all uniformly adhered in outer surface, and sodium metasilicate is inorganic bond, is hydrophilic, and cohesive force is strong, intensity is higher, acidproof Property, heat-resist, compound is 15~20wt% of cement, particle diameter is that 100~250 μm of zeolitic silica perforate hollow ceramics are micro- 60~75wt% of pearl, 5~15wt% of sodium metasilicate of modulus 3.2~3.5, the 3~10wt% of flyash and polyethylene of loss on ignition 1.1% Alcohol high hydroscopic resin 0.5~2.0wt% of fiber, then compound is sized mixing with 0.5~0.7 ratio of mud, ash is compound, finally The aluminium powder cream that compound gross weight is 0.2~1.0% is added, hydration reaction generation bubble, forms the porous slurries for expanding water suction, The weight of sponge brick is reduced, polyvinyl alcohol high hydroscopic resin fiber has extremely strong water imbibition, the sponge brick pressure resistance after water suction Spend constant;
The preparation of the porous sponge brick that catchments of 3rd step, heat-conducting 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 zeolitic silica perforate hollow ceramic microspheres:First by 80~200 μm of zeolites of particle diameter, 200~400 μm two Silica is by weight 70~85:20~30 compounds stir, and the percentage by weight sum of two kinds of components is 100%, is mixed Close material to size mixing by 0.5~0.7 ratio of mud, the compound that ash forms for two kinds of compositions of zeolite and silica, by centrifugal rotary Turn injection at a high speed and form microballon, then through 800~950 DEG C of expansions, 1000~1500 DEG C fire, quick cooling, formed wall thickness 50~ 100 μm, particle diameter is 100~250 μm of zeolitic silica perforate hollow ceramic microspheres, by high-temperature firing, forms modification Zeolitic silica composite ceramics resistance to compression microballon, the component of material is different, and the chemical property of modified material is also different, dioxy SiClx has strong crushing resistance, and chemical property is stable, and the smaller specific surface area of sized zeolite particles is bigger, and adsorption capacity is stronger, zeolite energy Ammoniacal nitrogen, organic matter and the heavy metal ion in water are enough adsorbed, the performance also with ion exchange and acidproof heat-proof, adjusts water PH value, sponge brick surface can be thermally conducted in soil.
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, zeolite can adsorb ammoniacal nitrogen, organic matter and the heavy metal ion in water, also with ion exchange and acidproof resistance to The performance of heat, adjusts the pH value of water, sponge brick surface can be thermally conducted in soil.
