Abstract
The invention discloses a recycling method of solid waste produced during autoclaved aerated concrete block production. The method is characterized in that the solid waste is crushed and is subjected to dry milling in a ball mill with lime, such that a cementing material is obtained; during autoclaved aerated concrete block production, the cementing material is used as a calcareous material for replacing lime with an equal mass. With the method, solid waste recycling is realized, production cost is reduced, factory solid waste stacking space is reduced, and solid environment pollution is alleviated. The method has a good environment-protection effect.
Description
Technical field
The present invention relates to during a kind of steam pressure sand aerated concrete block is produced the recycling method of the solid waste produced, is a kind of production method utilizing solid waste production steam pressure sand aerated concrete block in particular.
Background technology
Steam pressure sand aerated concrete block is a kind of material of construction, it is for main raw material with siliceous material (quartz sand) and calcareous material (lime and cement), with the vesicular structure that aluminium powder cream is formed through chemical gas generation method for foaming agent, complete hydrothermal synthesis reaction by steam press maintenance thus obtain the silicate concrete building block of the physical and mechanical properties such as certain ultimate compression strength.Steam pressure sand aerated concrete block is in process of production because the poor prognostic causes such as technique, operation, machinery produce waste product, usually this waste product is referred to as solid waste, the essence of this solid waste and steam pressure sand aerated concrete block is identical, and its main component is: CaO-SiO

2o system.This solid waste can do lagging material, but does merely lagging material and can not be consumed far away, and this solid waste is deposited in stockyard for a long time and not only wastes and stack place, also creates a kind of environmental pollution.
Summary of the invention
The present invention is the weak point for avoiding existing for above-mentioned prior art, the recycling method of the solid waste produced in providing a kind of steam pressure sand aerated concrete block to produce.
The recycling method of the solid waste that steam pressure sand aerated concrete block of the present invention produces in producing, its feature is: solid waste joined in lime and obtain agglutinate, agglutinate, cement, quartz sand, foaming agent and suds-stabilizing agent are joined in stirred pot according to certain proportioning, through cast, quiet stop shaping, cutting, steam press maintenance, produce steam pressure sand aerated concrete block.
The recycling method of the solid waste that steam pressure sand aerated concrete block of the present invention produces in producing, its feature is to carry out as follows:
(1) solid waste is broken into the fragment that particle diameter is not more than 50mm, then adds in ball mill together with lime according to 10% ~ 20% of lime weight and dry grind, obtain the agglutinate of 0.08mm square hole sieve screen over-size≤15%;
(2) quartz sand of 0.08mm square hole sieve screen over-size≤25%, silicon content 91 ~ 98% and powdery phosphogypsum are added water according to mass ratio 35:1 mix, make the mixed mortar of proportion 1.54 ~ 1.58kg/L;
(3) by mixed mortar 78.65 ~ 79.65 parts, agglutinate 10.48 ~ 11.1 parts, cement 6.64 ~ 9.25% parts: foaming agent 0.617 ~ 0.647 part and suds-stabilizing agent 0.06 part add in stirred pot successively, stir, mixing cast slip is obtained;
(4) described mixing cast slip is stopped shaping, cutting, steam press maintenance through quiet, obtain steam pressure sand aerated concrete block.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention solid waste is as the main raw material of production steam pressure sand aerated concrete block, solid waste does not directly participate in hydration reaction, mainly utilize the stability of its internal structure as the aggregate of reaction, be filled in hydrated product in steam pressure sand aerated concrete production process inner, improve the stability of aggregate needed for whole hydration reaction.
2, present invention achieves solid waste recycling to turn waste into wealth, not only solve solid waste and stack problem, more solve the puzzlement of solid waste environmental pollution.
Embodiment
Utilize the working system of solid waste production steam pressure sand aerated concrete block in the embodiment of the present invention, technical process comprise solid waste process, mixed mortar make, batching stir, quiet stop shaping, cutting, steam press maintenance.What the present invention produced is B06 level steam pressure sand aerated concrete block.
1, solid waste process: solid waste is broken into by jaw crusher the fragment that particle diameter is not more than 50mm, enter ball mill according to the 10-15% of lime weight together with lime to dry grind, the material gone out after mill is called agglutinate, its fineness≤15% (0.08mm square hole sieve), is stored in agglutinate in agglutinate storage tank for production and application.
2, mixed mortar makes: adopt the quartz sand of fineness≤25% (0.08mm square hole sieve), silicon content 91 ~ 98% and powdery phosphogypsum to add water according to 35:1 and mix, make the mixed mortar of proportion 1.54 ~ 1.58kg/L, be stored in mortar jar for production and application.
3, batching stirs: by mixed mortar 78.65 ~ 79.65 parts, agglutinate 10.48 ~ 11.1 parts, cement 6.64 ~ 9.25 parts: aluminium powder cream 0.617 ~ 0.647 part and suds-stabilizing agent (gas concrete special additive) 0.06 part add stirred pot successively, and after stirring, cast enters mould vehicle.
4, quiet stop shaping: in mould vehicle mixing cast slip through getting angry, multiviscosisty, hardened forming, obtain the base substrate with cutting hardness.
5, cut: specification as required carries out rip cutting and crosscut cutting to base substrate, after cutting, removing billet surface scrap stock, organize into groups into autoclave.
6, steam press maintenance: base substrate starts steam press maintenance operation after entering autoclave, autoclave pressure, first to autoclave vacuum pumping, was at the uniform velocity pumped into-0.06MPa at 20 ~ 30 minutes by (1); (2) carry out boost operations after exhausting vacuum, within 1.5 ~ 2 hours, be warming up to 1.2MPa; (3) constant voltage operation, keeps autoclave internal pressure 1.2MPa8 hour; (4) reduced pressure operation, is down to 0MPa by pressure uniform in 1.5 hours stills.Steam press maintenance becomes steam pressure sand aerated concrete block.
