Description
Technical field
The present invention relates to a kind of method that adopts solid waste material produce autoclaved lime-sand brick.
Background technology
Be described as the Pujiang all of crystal, crystal processing with foreign materials and sale have become one of Main Economic source of huge numbers of families.It flourish, rich vast farmers brother, has cultivated large quantities of social able person, has also driven the development of the relevant industries such as logistics transportation, packaging, has promoted the socioeconomic development of Pujiang.But due to crystal industry own characteristic, as state of the art require lower, areal distribution point is many, it is large to measure, wide, cause whole industry irrational distribution; The crystal processing with foreign materials of Pujiang County, taking family workshop type production as principal mode, causes the addressing of most of crystal processing enterprise improper, and environment protection treating facility is not in place, and the three wastes of generation produce considerable influence to surrounding environment, cause the ecotope of Pujiang increasingly to worsen.
The three wastes that glass quartz processing produces mainly refer to the glass waste, waste residue and the waste water that in the glass quartz course of processing, produce.Wherein, glass waste and waste residue, be referred to as again crystal solid waste.But along with crystal adds day by day increasing of workshop, spread to rural area at increasing crystal processing family, bring great difficulty to the supervision of environmental administration, cause crystal waste slag around to throw out without care, waste water disorderly row leaves about, make verdant verdant massif mountain forest decadence originally, No kernels or seeds are gathered, as in a year of scarcity for Man Di field, crops, river sewage crossing current so clear that you can see the bottom.Meanwhile, the noise producing in the course of processing, has had a strong impact on the life of surrounding resident, causes many social contradications such as neighbourhood's dispute.Show according to monitoring data in recent years, the pollution of crystal industry has caused Pujiang surface water quality obviously to decline, and people's productive life has also been subject to serious impact.Therefore, the processing problem of the crystal three wastes has become the extremely urgent problem of Pujiang County government, is not only weight but also heavy task.
Autoclaved lime-sand brick is used in all kinds of covil construction, the inner, external wall of utilities building and industrial premises and the basis in house, it is the product that replaces sintered clay brick, autoclaved lime-sand brick is with lime, gypsum and carbide slag, crystal glass solid waste, the quartz sand of suitable proportion, sand or packsand, through levigate, add water and mix, semidrying compression moulding also forms through steam press maintenance.
Summary of the invention
In order to solve the technical problem of above-mentioned crystal solid waste processing, the object of this invention is to provide a kind of method of utilizing crystal glass solid waste to manufacture autoclaved lime-sand brick, the method has the advantages that profit is useless, energy-conservation, save soil, environmental protection, can hold sexual development, and the autoclaved lime-sand brick of preparation has that intensity is high, not water funk, the feature of weathering resistance, corrosion-resistant, freeze-thaw-.
In order to realize above-mentioned object, the present invention has adopted following technical scheme:
Utilize construction waste and crystal glass solid waste to manufacture a method for autoclaved lime-sand brick, the method comprises the following steps:
1), by construction waste and packsand, break machine, pulverizer, trommel screen sub-sieve mixture particle degree by Hubei Province and reach powder below 0.5mm and stack and obtain construction waste and packsand mixing waste;
2) lime 10 ~ 15% or carbide slag waste material 15 ~ 20% and the construction waste and the packsand mixing waste 60 ~ 65% that crush, allocate again that crystal solid waste 10 ~ 20% is synthetic to be quantitatively transported in dual horizontal stirrer into, allocate 10%-15% water into, enter and carry out using conveying belt after action of forced stirring, belt elevator is sent in slaking silos, after 4-5 hour digestion reaction, emit slaking silos
3) with vertical strong powder machine, carry out the degree of depth and be crushed to rolling wheel machine rolling wheel and improve after its material surface reaction fine grinding homogeneous reaction, send into power press distribution cabins with conveying belt, cloth is expected on mould, compression moulding, the demoulding, to working face, obtains mould brick;
4) mould brick is delivered in autoclave, close still heated up by boiler air feed behind the door, reaching after 10 ~ 20MPa vapor pressure, constant temperature 4-5 hour, the still of can exitting out, go out still after finished product maintenance after 6 ~ 10 days, can use.
As further improvement, smelting heavy industry ZY1200A swaging machine during described power press adopts.
As further improvement, effective Ca0+Mg0 content of described lime is not less than 75%, and the fineness of calcium lime powder is that 4900/cm2 tails over and is not more than 15%.
The present invention also provides the autoclaved lime-sand brick that adopts above-mentioned method to prepare.
Preparation principle of the present invention is as follows: construction waste contains effectively high silicon oxide, aluminum oxide, ferric oxide, after raw material mixing rolling, fully aquation forms silicon, calcium oxide chemical combination after this vitreum and hydrate, produces chemical reaction, namely the silico-calcium reaction result under high temperature.The sour calcium of aquation silicon (aluminium) in chemical reaction is a kind of gluey vitreum, this gluey vitreum is also unstable, but under Additive, continuity reaction in time, solidify gradually, form a kind of high-intensity network structure, in addition raw material rational allocation and maintenance, thereby form the intensity of autotrophy brick, and crystal solid waste its be mainly glass ingredient, glass is silicon-dioxide, be incorporated into steam steam-cured middle as addition material, just form calcium pasc reaction result, solve again the headache problem that crystal solid waste waste material utilizes.Also accomplished the comprehensive utilization of resource.
The raw material granularity of autoclaved lime-sand brick of the present invention, humidity, rational apparatus and process intensive treatment for degree of mixing, reach after best plastic state through high pressure compression moulding, brick body is hardened rapidly, the time, more long-acting fruit was better, the practicality of brick is good, need not soak outward appearance neat while building a wall.Because this kind of strength of materials is high, good endurance, dimensional standard, profile is complete, and color and luster homogeneous has primitive simplicity and nature ground outward appearance, can make dry wall and also can make any outer decoration.Therefore, be a kind of extremely promising update building materials novel material product innovation of clay brick that replaces.
In sum, the present invention has following feature:
1) profit useless, energy-conservation, save soil, environmental protection, can hold sexual development;
2) starting material wide material sources, comprehensive utilization of resources;
3) preserve the ecological environment;
4) high, not water funk, the weathering resistance of intensity, corrosion-resistant, freeze-thaw-.
