The process of employed mixer, batching feeding machine is to operate under negative pressure, floats dirt and returns in the batching, removes the process of mass loss and dust emission from.

Beneficial effect of the present invention:

Solved the cracking problem of building masonry:

The main cause of the cracking problem of non-clay brick is because in article construction, because the contraction that the diffusion of water causes, this point is generally admitted for domestic and international research worker.The international most advanced level shrinkage factor is about 0.2mm/m, and domestic can only reaching more than the 0.6mm/m, even to more than the 1.2mm/m, and sintered clay brick has only 0.1mm/m.The present invention selects multiple solid, liquid phase chemical products commodity for use, industrial waste, Suo Leer composite gelled material slurries, again by improving processing technology as adjustable mixing speed, batching, operational procedure, and strict non-structure of baking bricks of across-the-board regulation and the physical and chemical performance such as raw material selected, shrinkage factor is dropped to below the 0.6mm/m, progressively solve the cracking problem.

Solve the brick face that freeze injury causes and peeled off the damage problem:

Because when rain, snow, wet, civil water etc. immerse the brick body, use under the regional condition below 0 ℃ at temperature, the repeatability freeze thawing can take place, thereby cause the brick surface successively to peel off year by year, if once take place just to form hidden danger building is had harm, the user just dare not use.Some small enterprise is for pursuing the lightweight of brick, and performance requirements such as insulation then reduce brick density significantly, unilateral think compression strength qualified be exactly high-quality, and do not note doing shrinkage factor, freeze-proof, water absorption rate etc., the hidden danger that the harm that these main performance index declines can cause the brick quality to descend forms.The present invention selects the additive on the multiple market for use, stop the water migration, select modified measures such as multiple stifled poromerics minimizing voidage such as phenolic resins for use, aspect processing technology, improve the uniformity that stirs material, stability, measure such as continuity, innocuousness reached when the winter, the frozen ground district used, and (or slight generation) freeze thawing phenomenon does not take place in brick inside, thereby freeze injury does not take place.

Solved no-firing brick normal take place return halogen, scum, problems such as buckling deformation:

These problems can cause that material takes place in use that the globule emits, glows bloom outward, the general tide that seeps water, physical dimension distortion etc., the present invention is by the major ingredient burdening calculation of science, the method of service property (quality), percent by volume and selecting not according to mole proportioning value batching, solid control is solid/than, consolidate/scope of water ratio, cooperate aforesaid multiple modified additive, cooperation raw materials control and quality control method reach to be participated in the reactant approximate equilibrium and the not enough or superfluous of key reaction thing not to take place and scum that cause, return the halogen phenomenon, solve the technical problem that these often occur.

Solved the low problem of shear strength of masonry:

The present invention reaches the back, surface and disposes the raising shearing strength by strengthen the adjustment of 6-8mm particle ratio in raw material.

Solved the environmental issue of autoclave curing sintering process system:

China has the enterprise of tame brickmaking more than 90,000 now, the standard brick annual production accounts for 70% 1,000 ten thousand small enterprises below the standard brick, account for less than 9% 3,000 ten thousand tax-free enterprises that enjoy more than the standard brick with output, like this under Xian Shi the national conditions, widely popularize substitute for clay fired brick product also can be because of fund strength and technician's deficiency, bring big difficulty to development.On the other hand, China's 8,000 hundred million standard brick annual productions what raw material that don't work all adopts sintering process, steam the so annual 2000000 tons of sulfur dioxide of just having an appointment of compression technology, 300,000,000 tons of carbon dioxide, 2,000,000 tons of dust, 100,000,000 tons consumption coal heat energy is discharged in the atmosphere, 8.5% of suitable China annual all C02, S02 total release, as seen the seriousness of secondary pollution, and 90,000 enterprises must be the distributions of disperseing because of transportation freight rate problem, (it is 100 kilometers market that each producer occupies about radius), pollution is also just very extensive, and environmental issue is just particularly important.

The present invention has in mind from the brick inner structure, takes the technology path of " unburned, excellent foster, optimization physical-chemical reaction is optimized and selected additive, innovation cementing material ", solves the every key issue of above-mentioned 1.1-1.5 with this.Have the brick product of significantly improving quality and fundamentally solve energy-saving and emission-reduction and realize that nuisance is near zero-emission.Reduce investment again and save the area, reduce cost simultaneously, favourable development improves the performance of enterprises, social benefit and economic benefit.The art of this patent can be widely used in the technological transformation of 90,000 small enterprises, reaches energy-conservation, reduction of discharging, high-quality does not account for the farmland, and remarkable benefit is applied to the technology upgrading of supercharging brick after also can testing cautiously, for China's development novel wall material is contributed.
