Description
Technical field
The invention belongs to building block field, is related to a kind of manufacture method of the aerated bricks that drift-sand is major ingredient.
Background technology
Air-entrained concrete building block is a kind of light porous, insulation, fire protecting performance is good, can follow closely, can saw, can dig and have
There is the construction material of certain shock resistance.
Aerated-block has two classes, sand aerated concrete block and powder ash air-entrained concrete building block.Fly ash aerated coagulation
Earth building blocks typical case's formula for raw stock and consumption：Flyash：Content ratio 70%；Every cubic metre of consumption：350kg；Cement：Content
Ratio 13.8%；Every cubic metre of consumption：25-30kg；Calx：Content ratio 13.8%；Every cubic metre of consumption：140-150kg；
Ardealite：Content ratio 2.96%；Every cubic metre of consumption：15kg；Aluminium powder：Content is micro；Every cubic metre of consumption：0.4kg.
Sand aerated concrete block typical case's formula for raw stock and consumption：Sand：Content ratio 69.2%；Every cubic metre of consumption：350kg；
Cement：Content ratio 13.8%；Every cubic metre of consumption：70kg；Calx：Content ratio 13.8%；Every cubic metre of consumption：
70kg；Anhydrite（Gypsum Fibrosum）：Content ratio 2.96%；Every cubic metre of consumption：15kg；Aluminium powder：Content is micro；Per cubic metre disappears
Consumption：0.4kg.
Flyash that two class aerated-blocks are used, sand are both needed to grinding, reach and can be used after certain particle size.
Drift-sand is constantly blown by wind in desert, then the sand bed for falling.Drift-sand is mainly by landwaste, Anhydrite and quartz
Three kinds of granule compositions, dioxide-containing silica highest, next to that aluminium sesquioxide.China has the vast desert area of area, prevents
Control desert and be always the important and problem of difficulty, will be benefit the nation and the people big good if can be turned waste into wealth using Desert Resources
Thing.
The content of the invention
The present invention seeks to propose that one kind manufactures aerated bricks method using desert drift-sand, turn waste into wealth.
The technical scheme is that：A kind of drift-sand is the manufacture method of the aerated bricks of major ingredient, and drift-sand is sieved, and takes
The mesh of 120 mesh -180 as raw material, drift-sand, desulfurated plaster, water are added slurrying pond stirring pulping, ratio be water per ton correspondingly
300 kilograms -350 kilograms of drift-sand, 10 kilograms -20 kilograms of desulfurated plaster, the slurry feeding oleo stock tank in slurrying pond is stand-by；Weigh water
Mud, calcium lime powder, aluminium powder, the ratio of weighing be every cubic metre of oleo stock 50 kilograms -90 kilograms of cement of correspondence, calcium lime powder double centner -
110 kilograms, 0.5 kilogram -0.6 kilogram of aluminium powder；The material of weighing adds in order casting machine, first adds oleo stock, adds water mud, calculogenesis
Ashes, stirring mixing, is passed through steam in whipping process, cast built-in temperature rises to 45-50 DEG C during stirring 200-230 second, so
Backward casting machine adds aluminium powder, then Jing to stir for -55 seconds 45 seconds, and mixing is completed, and pour mass goes out casting machine and enters resting room, and resting room is logical to steam
Vapour, pour mass is rested 2.5h-3h, and pour mass goes out resting room, and to cutting machine, pour mass is cut into customer demand to transhipment pour mass
Size, after cutting block send into steam-cured kettle, 1.3MPa in steam-cured kettle, steam press maintenance 7-8h, then steam-cured kettle blood pressure lowering, open,
Block goes out, and last block is transported to finished product stock ground and waits natural drying.
Further, high alveolitoid detergent is additionally added when adding aluminium powder, addition is every cubic metre of oleo stock correspondence 0.05 thousand
Gram -0.06 kilogram.
Preferably, block is entered after steam-cured kettle after cutting, first steam-cured kettle is evacuated to into -0.04MP, then fills into steam,
Respectively when 0.35MP, 0.7MP is reached, draining once, reaches pressure in steam-cured kettle and continue after 1.3MP 7-8 hours, and this continues
The temperature in the kettle of time period reaches 200 DEG C.
Further, when there are multiple steam-cured kettles, the method for point gas is taken during steam-cured kettle blood pressure lowering, the interior of blood pressure lowering kettle will be needed
Portion's steam is imported in the kettle of other firm evacuation, after each kettle balance to be achieved, the inside residual steam for needing blood pressure lowering kettle is discharged, etc.
Kettle is driven after kettle inside and outside air pressure balance.
The invention has the beneficial effects as follows：Using drift-sand be raw material, aboundresources, not only produce direct economic benefit,
" desert change gold ", also slows down erosion of the desert edge to oasis.Sand, stone need not be ground as former technology, be simplified
It is step, cost-effective.
