Abstract

The invention discloses a method for preparing an aerated brick from waste paper, which comprises the following step: (1) taking the following raw materials on dry basis in parts by mass: 20-30 parts of quicklime, 15-18 parts of coal gangue, 12-14 parts of cement, 20-30 parts of active waste slag, 5-7 parts of aluminum oxide, 4-6 parts of modified loess and 2-5 parts of defoaming agent. The method has the advantages of high construction waste consumption, energy saving and environment friendliness, relieves the problem of environmental pollution caused by stacking of the construction waste, and provides a new raw material for hollow bricks.

Description

A kind of waste and old paper product prepares aerated bricks method
Technical field
The present invention relates to building material field, specifically belong to a kind of waste and old paper product and prepare aerated bricks method.
Background technology
Containing a large amount of suspended solid, organic pollutant and toxic substance in black liquid, be directly discharged in water body and can cause serious pollution.Its main harm has: the paper waste containing a large amount of fiber, pigment and inorganic salt can make water body blackening, and has special foul smell; Biochemical oxygen demand (BOD) containing the black liquid of high concentration organic contaminant up to 5000 ~ 40000g/L, can consume the dissolved oxygen in water, affect water quality in a large number; In black liquor, a large amount of alkaline matter existed can make the pH value of water body sharply raise, and destroys the balance of water body environment.
The process of black liquid combines with industrial production, is a kind of new research direction.
Summary of the invention
The object of the present invention is to provide a kind of waste and old paper product to prepare aerated bricks method, black liquid consumption be large, energy-conserving and environment-protective, alleviate the problem of environmental pollution that black liquid process brings, simultaneously for aerated bricks provides new raw material sources.
Technical scheme of the present invention is as follows:
A kind of waste and old paper product prepares aerated bricks method, it is characterized in that carrying out in accordance with the following steps:
(1) the butt raw material of row mass parts, is taken off:
Unslaked lime 20-30 part
Coal gangue 15-18 part
Cement 12-14 part
Active waste residue 20-30 part
Aluminum oxide 5-7 part
Modified Loess 4-6 part
Defoamer 2-5 part;
(2), first by unslaked lime and the fragmentation of active waste residue, rolling is carried out again with modified Loess, aluminum oxide, coal gangue and appropriate black liquid shaping after levigate, rolling is shaping adds defoamer simultaneously, and green compact building block is maintenance 20-22h in 0.8-0.9Mpa sweating room, then sends carbonizing chamber to;
(3), by stack gas by blower fan and Cemented filling to carbonizing chamber, carbonizing chamber C0 2the concentration of gas is 7 soil 12%, and the temperature of carbonizing chamber controls, at 40 ~ 60 DEG C, to make relative air humidity remain on 90-95%, and carbonization time is 28 ~ 32h;
(4) building block, after carbonization cuts into corresponding size, obtains aerating hollow brick finished product.
Take off the butt raw material of row mass parts:
Unslaked lime 25 parts
Coal gangue 16 parts
Cement 13 parts
Active 25 parts, waste residue
6 parts, aluminum oxide
Modified Loess 5 parts
Defoamer 4 parts.
The present invention compared with prior art tool has the following advantages:
Compared with other material of construction, the black liquid consumption that the present invention adopts is large, simultaneously a large amount of uses coal gangue and modified Loess, energy-conserving and environment-protective, alleviates the problem of environmental pollution that black liquid process brings, simultaneously for aerated bricks provides new raw material sources.
Embodiment

Active 25 parts, waste residue
6 parts, aluminum oxide
Modified Loess 5 parts
Defoamer 4 parts;
(2), first by unslaked lime and the fragmentation of active waste residue, rolling is carried out again with modified Loess, aluminum oxide, coal gangue and appropriate black liquid shaping after levigate, rolling is shaping adds defoamer simultaneously, and green compact building block is maintenance 20-22h in 0.8-0.9Mpa sweating room, then sends carbonizing chamber to;
(3), by stack gas by blower fan and Cemented filling to carbonizing chamber, carbonizing chamber C0 2the concentration of gas is 7 soil 12%, and the temperature of carbonizing chamber controls, at 40 ~ 60 DEG C, to make relative air humidity remain on 90-95%, and carbonization time is 28 ~ 32h;
(4) building block, after carbonization cuts into corresponding size, obtains aerating hollow brick finished product.
