Problems solved by technology

However, after the waste residue fly ash enters the landfill, it is exposed to the sun, rain, and wind, and the harmful components in it can directly or indirectly cause water resources to be polluted through soil, surface or underground water bodies, etc.
Garbage ash also contains a large amount of fine powder and particles, which...

Embodiment 1

[0046] Garbage ash, which is the daily domestic garbage of residents and all kinds of garbage cleaned by the office space, large shopping malls, farmers' markets, landscaping, and sanitation systems on roads, streets, squares, parks, and other public places, is discharged after incineration and power generation After sorting, crushing, and magnetic separation to remove waste metal, and then crushing, drying, grinding, and sieving, the waste residue is made into powder with a particle size of less than 0.045mm for use;

[0047] The discarded polystyrene foam is used by the manufacturer to ensure the safety of high-end industrial products, household appliances and other valuable and fragile commodities during transportation. The padded packaging materials and disposable tableware produced by polystyrene, these commodities arrive The packaging is discarded in the hands of consumers, resulting in a large amount of discarded foamed plastics, referred to as white garbage, which is ma...

Embodiment 2

[0051] Take 0.8kg of sodium dodecylbenzenesulfonate foaming agent, 0.4kg of polyacrylamide foam stabilizer and 24kg of water and mix evenly to make a diluted foaming liquid. After filtering, store it in the storage tank and seal it for later use. It is automatically pumped into the foaming machine, and foamed by a high-pressure air foaming machine to make foam;

[0052] Get the rubbish ash powder material 48kg that embodiment 1 prepares, waste polystyrene foam powder material 24kg, Portland cement 35kg, calcium oxide powder material 20kg, calcium sulfate powder material 6kg, bentonite 4kg, polycarboxylate high-efficiency water-reducing 0.8kg of sodium carboxymethylcellulose, 0.5kg of sodium carboxymethyl cellulose, 0.06kg of sodium lauryl sulfate, 0.5kg of aluminum sulfate, 0.6kg of sodium chloride, 0.06kg of borax and 42kg of water, and the above raw materials were stirred evenly The mixture is made, and it is fully controlled by a microcomputer. The spiral tube conveyor is u...

Embodiment 3

[0054] Take 0.5kg of sodium dodecylbenzenesulfonate foaming agent, 0.3kg of polyacrylamide foam stabilizer and 15kg of water and mix evenly to make a diluted foaming liquid. After filtering, store it in the storage tank and seal it for later use. It is automatically pumped into the foaming machine, and foamed by a high-pressure air foaming machine to make foam;

[0055] Get the rubbish ash powder material 38kg that embodiment 1 prepares, waste polystyrene foam powder material 18kg, Portland cement 30kg, calcium oxide powder material 15kg, calcium sulfate powder material 4kg, bentonite 2kg, polycarboxylate efficient water-reducing 0.5kg of sodium carboxymethyl cellulose, 0.04kg of sodium lauryl sulfate, 0.3kg of aluminum sulfate, 0.4kg of sodium chloride, 0.04kg of borax and 36kg of water, and the above raw materials were stirred evenly with a biaxial mixer The mixture is made, and it is fully controlled by a microcomputer. The spiral tube conveyor is used to send the mixture t...

Abstract

The invention relates to a foam concrete block produced with waste ash and a manufacturing method thereof. The manufacturing method is characterized in that waste ash, waste polystyrene foam, portland cement, calcium oxide, calcium sulfate, bentonite, polycarboxylate superplasticizer, sodium carboxymethyl cellulose, sodium lauryl sulfate, aluminum sulfate, sodium chloride, borax and water are used as raw materials, the raw materials are uniformly mixed by a double-shaft mixer into mixture, foam is prepared through mixing the mixture with sodium dodecyl benzene sulfonate and polyacrylamide, a computer is used for fully automatic control, the mixture is fed by a spiral tube conveyor into a high-speed mixing and soaking slurry-producing mixer and is mixed well into paste type foam slurry, the slurry is poured into a die, shaped and then delivered into a curing room for curing, the cured product is fed into a stripping machine for stripping, stacking, packaging and storage on a yard are performed after stripping, and thus the foam concrete block product made of the waste ash is prepared. The product has the advantages and effects of light weight, heat preservation, thermal insulation, sound insulation, capabilities of being nailed, sawn and processed into different specifications, high strength, no pollution, low cost and good profits, and complies with national requirements for energy conservation, emission reduction, development of the low-carbon economy and environmental protection.

Description

technical field [0001] The invention relates to a foamed concrete block produced from garbage ash. Specifically, it is sorted, crushed, pulverized and screened from domestic garbage incinerated slag and waste polystyrene foam. The foamed concrete block produced with the powder as the main raw material belongs to the field of waste treatment. [0002] The invention also relates to a method for manufacturing the garbage ash foamed concrete block. Background technique [0003] Foamed concrete is also known as foam concrete. It is a new type of lightweight wall material formed by dispersing foam in cement slurry, using garbage ash and waste polystyrene foam as fillers to solidify the foam through gelation. Its outstanding feature is the use of mechanical foaming to form foam pores in the concrete, which is a kind of porous concrete, which makes the concrete lightweight and thermally insulated. The foaming agent is made into foam by mechanical means, and then mixed with silico...
