Abstract
The present invention relates to a special-purpose additive for fly-ash sintered bricks, which is made from papermaking waste water, a mineralizing agent and an organic surfactant. The method for producing the special-purpose additive comprises: the papermaking waste water is heated to 90 to 100 DEG C and added to the mineralizing agent in the proportion of 10 to 1 to react with the mineralizing agent for 10 to 20 minutes, the papermaking waste water and the mineralizing agent are cooled to the ordinary temperature, and 0.1 to 1% of the organic surfactant is stirred with the papermaking waste water and the mineralizing agent to be dissolved so as to obtain the finished product. The present invention has the advantage of low manufacture cost. When used for making bricks, the special-purpose additive can enhance the plasticity of raw materials, enhance the strength of green bricks and eliminate the harmful substances in fly ash.
Description
Technical field:
The present invention relates to a kind of brickmaking additive, particularly a kind of special-purpose additive for fly-ash sintered brick.
Background technology:
There are clay brick field more than 120,000 families in the whole nation, fires 7,000 hundred million of clay bricks every year, and 14 billion cubic meters that fetch earth are equivalent to ruin 1,200,000 mu in field, 6,000 ten thousand tons in consumption coal.The relevant expert points out, this brickmaking mode has the 7% arable land raising country of 22% population in the world for such one of China, and this waste can not be ignored.The flyash of the annual discharging in the fuel-burning power plant in the whole nation takes up an area of more than 5.4 ten thousand mu in addition.Be the protection soil, protection environment, the saving energy, national departments concerned was once given notice, and forbade in limited time baking bricks with clay, advocated and baked bricks with the flyash substitute for clay.Existing for this reason clay brick field generally adopts the method that fly ash is baked bricks in clay, and the flyash of being mixed is about 30%, this ratio does not reach requirement far away, and because the specialist additive that do not have fly ash to bake bricks, to making the green brick forming difficulty, and insufficient strength.
Summary of the invention:
The objective of the invention is to provide a kind of special-purpose additive for fly-ash sintered brick of using for raw material brickmaking with flyash in order to overcome the deficiencies in the prior art.Do not see by retrieval the pertinent literature report is arranged.
The object of the present invention is achieved like this: it is made up of paper waste, mineralizer, tensio-active agent, by following step production, paper waste is heated to 90-100 ℃, add mineralizer reaction 10-20 minute in 10: 1 ratio then, after making it reduce to normal temperature, add tensio-active agent 0.1-1%, after the stirring and dissolving, be finished product.
Described tensio-active agent is a sodium humate.
Described tensio-active agent is a wooden calcium sulfonate.
Use brickmaking of the present invention, flyash is the main raw material of brickmaking, accounts for more than 70%, and the usage quantity of clay is minimum, can greatly save the soil and then reach national requirements; And the low cost of manufacture of additive, usage quantity is few, only is 1%.Use brickmaking of the present invention, not only use easy to operately, can also improve the plasticity of raw material effectively, help blank forming, strengthen the intensity of adobe, improve the resistance to cleavage of brick.High-dosage flyash sintered brick, in light weight, good heat preservation performance can be eliminated the objectionable impurities in the Benzpyrene effectively; Help existing clay brick field and change the line of production, be easy to big area and promote; High-dosage flyash sintered brick, the volume of flyash brings up to 70% by 30%, and cement comsumption is big, and to the protection soil, the protection environment reduces and pollutes, and saving the energy has remarkable economic efficiency.
Embodiment:
Below in conjunction with embodiment in detail the present invention is described in detail.
The present invention is a kind of specialist additive with brick making from fly-ash, is made up of paper waste, mineralizer, organic active agent.It is heated paper waste to 90-100 ℃ by following step production, adds mineralizer then in boiling water, and the part by weight of papermaking (boiling) waste water and mineralizer is 10: 1.The mineralizer that the present invention uses is a Sodium salts humic acids, and its ratio embodiment represents with following table:
Table (weight ton)
| Make system (boiling) waste water | 4 | ?5 | ?6 | ?7 | ?8 | ?9 | ?10 |
| Sodium humate | 0.4 | ?0.5 | ?0.6 | ?0.7 | ?0.8 | ?0.9 | ?1 |
After the present invention adds sodium humate (mineralizer) according to the above ratio, reacted 10-20 minute, make it reduce to normal temperature; In waste water and mineralizer mixture are boiled in papermaking, add tensio-active agent 0.1-1% (weight) then, after the stirring and dissolving, be finished product.
Tensio-active agent of the present invention is a wooden calcium sulfonate, and its add-on is fitted the amount of mixture and decided.General per hundred jin of mixtures add 1% wooden calcium sulfonate.
The present invention can be made into liquid or powder, and liquid is on-the-spot to be used, and powdery is packed to be transported outward.
During use, the present invention's (liquid) is directly mixed in the flyash material, mix material and make adobe.
Add-on of the present invention, according to the difference in season and difference, it is fixed to come according to the water content of flyash, clay, as: summer high humidity, the add-on of additive is little, otherwise also anti-.
Claims (1)
1, a kind of coal ash sintering brick additive is made up of paper waste, mineralizer, tensio-active agent, it is characterized in that: it presses following step production,
A, paper waste is heated to 90-100 ℃, add the mineralizer sodium humate in 10: 1 ratio then, 1 ton of paper waste adds 0.1 ton of mineralizer sodium humate, reacts 10-20 minute, makes it reduce to normal temperature;
B, add the tensio-active agent 0.1-1% of wooden calcium sulfonate in the mixture of paper waste and sodium humate, per hundred jin of mixtures add 0.1-1 jin wooden calcium sulfonate, after the stirring and dissolving, are finished product.
