Description
Technical field
What the present invention relates to is the land resources protection soil conservation in field, the refuse treatment of field of Environment Protection, the building wall material, roofing tile, road brick etc. of building materials field.
Background technology
At present, the brick class of building by laying bricks or stones that construction industry uses is mostly clay brick, also a small amount of building block is had, the use of clay brick, this has just caused, and a large amount of soils is occupied, loss, simultaneously, the transformation in enormous quantities in old city, various places are bought again the region of departing from urban district and are used for toppling over, burying rubbish, and after building waste being toppled over, buries, farmland just forever can not utilize; In addition, a large amount of inorganic industrial waste residues is also occupying in large quantity, is engulfing soil; Further, some municipal effluents, trade effluent are also constantly discharging, and these just seriously do not destroy environment, cause the severe contamination of environment.All these, all unrestrictedly engulfing the soil and water resources that the mankind depend on for existence, threaten the existence of the mankind.
At present, market has had the production technology of instead of clay brick, but these mostly to make binding agent with cement unburned, its range of product and its quality are limited to; Some is fired, but its product fired, technology and the starting material utilized have certain limitation, the firing atmosphere that some needs are special, the garbage raw material that some needs are special, also contain some composition etc. in the rubbish handled by the needs had or waste residue, this brings certain limitation to the process of solid refuse.
Summary of the invention
The soil of depending on for existence to make the mankind can not be a large amount of loss, in order to allow the environment gone from bad to worse make moderate progress, to take a turn for the better, also call to respond country, be supplied to as early as possible a kind of new alternative clay brick of construction industry, watt new material of construction.
The invention provides a kind of brand-new binding agent.Utilize the technology of the manufacture brick and tile of Partial mature, building waste, industrial residue etc. are processed through certain fragmentation, be blended into a certain amount of binding agent of trade effluent or municipal effluent that uses again and make flux, handled rubbish and waste residue is made to have certain plasticity-, the inorganic materials simultaneously had under high temperature fires proterties, be made into required brick, watt shape, be fired into new material of construction.Its concrete principle is: brick and tile material enters in kiln to be fired, under certain kiln temperature, be mixed into the flux material now melting in binding agent wherein, flow in this case, therefore penetrate into brick, watt each position pore in, when brick, watt when cooling, flux material is just in solid state, by the rubbish particle around it, upper industry waste residue material bonding get up, become a kind of semi-sintered condition, there is good anti-folding, the brick of ultimate compression strength, watt material.
According to different forming methods and different moulding processs, binding agent can make dry powder, also can make muddy.Binding agent used, then process separately, it is the material of one or more tool flux performances, the Xylo-Mucine adding 1-10 ‰ makes suspension agent and cakingagent, according to different forming methods, add the water of 50-100% again, slurry made when being ground to the fineness of more than 100 orders in ball mushroom machine.Also additive method can be utilized to be processed into powder, and the material with flux performance can be a kind of industrial residue, also can be a kind of slag, also can allocate with multiple slag charge.Water used can be municipal effluent, and also can be trade effluent, domestic water etc., salt water also can be quoted in place with good conditionsi.Have in the material of flux performance, because of the compound containing a small amount of lead, zinc, boron etc., and these are plumbous, zinc, boron etc. are all strong flux, be melting at relatively low temperature, thus generation mobility, can infiltrate randomly in the gap of the material of handled building waste or waste residue, when being cooled to normal temperature, flux material solidifies, thus building waste, waste residue bonding are got up.The material with flux performance also can be a kind of mine tailings containing the strong flux material of such low temperature: lead ore residue, zinc ore slag, Boron slag etc.; They have the characteristic that low temperature melts by force equally.
The proportioning of binding agent: lead skim (or cadmia, boron slag) or its slag 100, additional Xylo-Mucine 1-10 ‰.When there being special requirement, can add a certain proportion of feldspar 10%, kaolin 5% etc. outward, what have also wants additional quartzy 10%.Part Xylo-Mucine can be replaced with unselected clay.
Feature of the present invention: 1.. the major ingredient of binding agent used is the mixture of one or more waste residues or slag, and itself is also industrial refuse, meanwhile, regulates the proterties under its normal temperature state with Xylo-Mucine; 2.. physical bond of burning till result mainly binding agent and handled storeroom of the present invention, instead of the solid state reaction between them, solid state reaction is mainly inner at binding agent; 3.. handled building waste and industrial residue, when mixing, without fixed proportion, without immobilized particles grating, as long as in certain size range; 4.. pyroreaction of the present invention, without any need for special atmosphere and temperature lift-down curve, only needs the sufficient melting of binding agent under high temperature, flows; 5.. building waste of the present invention refers to all inorganic building wastes, all inorganic industrial waste residues that industrial residue refers to.
The scheme that the present invention takes is: 1.. building waste, industrial residue fragmentation, to certain granularity, (most of industrial residue is as inherently very tiny in acid sludge, alkaline residue, copper ashes, red mud etc., do not need fragmentation process again), according to different forming methods, add binding agent; General, the binding agent ratio be blended into is 1-20%, if 2.. make Brick for building or roofing tile, then mixed and made walk shape, send in pug mill and refine, when brick is built in making by laying bricks or stones, can from the direct cutting forming of pug mill mouth (granularity of now, handled rubbish the most very much not should more than 4mm); When making roofing tile, then with press forming or manual forging method (binding agent dry powder now more suitable, now the granularity of handled rubbish is maximum is no more than 2mm); 3.. when making road, square brick, adopt the dry prilling process of spray (now the granularity of handled rubbish is maximum is no more than 1mm), be first made into slimy slurry, send in spray-drying tower, make wet-milling.Also dry method powder process can be adopted, by refuse powder or the industrial residue of butt, directly mix a certain amount of binding agent, add the water Homogeneous phase mixing of 3-5%, make the siccative containing moisture 3-5%, send into compression moulding in brick pressing machine (when the moisture content ensured in powder and binding agent ratio, binding agent now can be dry powder, also can be slimy).
The invention has the beneficial effects as follows: solve the environmental pollution gone from bad to worse and occupying farmland that building waste causes, checked the impetus in the utilized farmland of day by day reducing, purified water resource environment, meanwhile, also met the building materials demand day by day increased.Tentatively compare produced new Brick for building and clay matter porous baked brick, new building materials have obvious advantage: dimensional standard, do not shrink; Due to its technical characterstic, determine new brick and there is the high performance of intensity, far above the vitrified brick of other raw material types; More because it is flux vitreous adhesion character, be again semi-sintered condition, the building waste raw material utilized, industrial residue are also mostly through pyroprocessing, so weathering resistance performance spy is good; In addition, also there is the advantage that day treating refuse amount is large, can large suitability for industrialized production be carried out; Further, there is at existing pottery, refractory materials, emery wheel etc. the industrial enterprise of kiln, can change the line of production and produce, have that cost is low, less investment, stream money less, the feature of instant effect.
