Abstract
A technology for quickly making powdered coal ash brick without steam curing features that the industrial waste such as powdered coal ash, cinder, calcium carbide dregs, slags, iron dregs, phosphorus dregs and ardealite are used as basic raw materials and the high molecular compounds are used as additive. It includes such technological steps as metering, milling, digestion, milling again, shaping and hot-air cyclic reaction. Its advantages include no need of steam boiler, less investment on equipment, low energy consumption and short productive period.
Description
The invention provides a kind of non-evaporating processing method of producing flyash brick fast of supporting.
At present, flyash brick has obtained using widely in industry and covil construction.Flyash brick is a kind of novel wall material of construction that utilizes industrial wastes such as flyash, cinder, carbide slag to produce.Flyash can mix use with cinder, also can use separately separately.The processing method of traditional mode of production is, with industrial waste and additive restir, digestion, rolling, shapings after metering such as flyash, cinder, carbide slags, again through vapor cure finished product; Adopt this processing method, often need autoclave or steam boiler, facility investment is big, energy consumption is more.The processing method of existing production changes above-mentioned vapor cure into natural curing, i.e. natural curing at normal temperatures and pressures; Adopt this processing method no doubt to save this processing sequence of vapor cure, still, natural curing often needs tens of days time, even can't produce in the winter of cold, thereby causes taking in a large number of place.
The objective of the invention is to: on the basis of the processing method of traditional and existing production flyash brick, improve, work out a kind of processing method that can produce flyash brick at normal temperatures and pressures fast.
The present invention is achieved in that basic raw material adopts flyash, cinder, carbide slag, industrial residues such as slag, scum, phosphorus slag, phosphogypsum.Wherein flyash can mix use with cinder, also can use separately separately; Carbide slag also can replace with calcium lime powder.Add the sharp composite high-molecular section material that adopts.Basic raw material and water are ground at the enterprising road wheel of intermittent type wheel roller after metering, make various batchings obtain preliminary fragmentation, stirring, activation in the process of rolling; Compound after the rolling is sent to the digestion chamber and digests, and the process of digestion makes various weighing rooms that preliminary chemical reaction take place and relevant physical change takes place; Carry out the rolling second time after the digestion, in the process of the rolling second time, spray in the compound the composite high-molecular additive is vaporific, rolling makes that full and uniform hybrid concurrency is given birth to corresponding chemical reaction and relevant physical change between various batchings, the additive for the second time; After the rolling compound is sent into brick pressing machine compression moulding for the second time; After the moulding reaction chamber is sent in adobe and carried out the hot air circulate reaction, warm air is supplied with by straight-through circulating hot-blast stove, in this course, warm air has been created the condition of various weighing room aquations and hydrothermal synthesis reaction, contain multiple strong electrolyte in the additive, have diminishing and early strength function, can promote the carrying out of aquation and hydrothermal synthesis reaction, thereby shorten the reaction times; After the hot air circulate reaction finished product.
The invention has the advantages that, compare, saved main equipments such as autoclave, steam boiler, saved facility investment, reduced energy consumption with traditional vapor cure formula producing and manufacturing technique and existing natural curing formula producing and manufacturing technique; The reaction of employing hot air circulate has promoted carrying out smoothly of aquation and hydrothermal synthesis reaction, has shortened the production cycle, has reduced the place and has taken.
The present invention is provided by following embodiment's:
This processing method includes metering, the moulding process program of prior art, and it is made of following each steps in sequence: a, flyash, cinder, carbide slag, slag, scum, phosphorus slag, each industrial waste of phosphogypsum and water are measured; Wherein, flyash can mix use with cinder, also can use separately separately, and carbide slag can replace with calcium lime powder; Various batchings must and meet respective standard through detection before metering.After b, the metering compound is sent into the intermittent type wheel roller and carry out the rolling first time; Make that in this process various batchings obtain preliminary fragmentation, stirring, activation.C, the first time are sent compound into the digestion chamber after the rolling and digest; In this process, preliminary chemical reaction takes place and corresponding physical change takes place in various weighing rooms.After d, the digestion compound and composite high-molecular additive are sent into the intermittent type wheel roller and carry out the rolling second time; In this process, the composite high-molecular additive is vaporific spraying in the compound and carries out the rolling second time with compound; The composite high-molecular additive contains multiple strong electrolyte, can increase carbide slag or lime solubleness, can activate the silicon-dioxide in flyash or the cinder and the activity of aluminium sesquioxide; The process of rolling makes that full and uniform hybrid concurrency is given birth to corresponding chemical reaction and relevant physical change between various batchings, the additive for the second time.E, the second time are sent compound into the compression moulding of disc type brick pressing machine after the rolling; Adopt large tonnage disc type brick press in this step, it can guarantee the physical dimension and the compaction rate of adobe.After f, the moulding reaction chamber is sent in adobe and carried out the hot air circulate reaction; Warm air in the reaction chamber is supplied with by straight-through circulating hot-blast stove; The warm air that straight-through circulating hot-blast stove produces is by induced draft fan and carry airduct to send into reaction chamber, and with the heating that circulates in the straight-through circulating hot-blast stove of the freezing air suction in the reaction chamber; Cross in the kind at this, warm air has been created the condition of various weighing room aquations and hydrothermal synthesis reaction, increased the concentration of hydroxide ion after the strong electrolyte hydrolysis in the additive, replenished under hydrothermal condition because calcium hydroxide is separated out the deficiency that causes hydroxide ion concentration, hydroxide ion combines with sodium ion and the sodium hydroxide that forms makes flyash, silicon in the cinder, the silicon-dioxide of aluminum vitreous acts on the water glass that generates solubility with it, water glass is hydrolyzed into the silicic acid of sodium hydroxide and solubility again, reaction again and again so again and again, silicon-dioxide in the compound is transformed into lime is had very big active mensuration dissolubility silicic, generate the hydrated calcium silicate gum material, with lime-ash seed lac knot together, thereby make calcium hydroxide and silicon, the surface reaction of aluminum vitreous speeds up, then make adobe finish aquation and hydrothermal synthesis reaction in the short period of time, produce hydrated calcium silicate, drated calcium aluminate and aquation calcium sulphoaluminate.After the reaction of g, hot air circulate finished product.
Produce flyash brick according to this processing method, its cost has reduction by a relatively large margin, and its physical strength and other physical and mechanical property indexs also increase.
