Abstract
The invention discloses a burn-free spherical attapulgite fly ash ceramsite. The key point of the technical scheme is as follows: the burn-free spherical attapulgite fly ash ceramsite comprises attapulgite clay tailing powder, fly ash, bentonite tailing powder, stone ash and cement. The ingredients of the burn-free spherical attapulgite fly ash ceramsite are mixed, granulated, cured, screened and packaged to obtain the burn-free spherical attapulgite fly ash ceramsite. The burn-free spherical attapulgite fly ash ceramsite is of spherical shape, has rough and hard surface and has a lot of fine pores in the interior; and the burn-free spherical attapulgite fly ash ceramsite is a construction ceramsite with high strength, low thermal conductivity, stable chemical property, durability and good heat insulation and sound insulation effect. The comprehensive utilization of fly ashes and tailings in producing the burn-free spherical attapulgite fly ash ceramsite is beneficial for increasing the resource utilization rate, turning waste into wealth, reducing land usage, protecting the environment and purifying the environment; and the burn-free spherical attapulgite fly ash ceramsite disclosed by the invention is suitable for producing ceramsite concrete as well as heat insulation and sound insulation materials.
Description
Technical field
The present invention relates to haydite, be specifically related to a kind of unburned spheroidal attapulgite flyash haydite.
Background technology
Mineral Resources in China 80% is for being total to associated minerals, and a large amount of valuable resources retain among the mine tailing, and tailings impoundment need take a large amount of soils.Exceed the time limit in a lot of mine tailing storehouses or sh is used, even violation operation, makes the mine tailing stock in great potential safety hazard, and the people's property and the life security of surrounding area caused serious threat.
Flyash is to receive the thin ash of catching the flue gas behind coal combustion; Flyash also is the main solid waste that the coal-burning power plant discharges; Be one of bigger industrial residue of the current discharge capacity of China, along with development of electric power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; If entering water system can cause the river to silt up, and toxic chemical substance wherein also can work the mischief to human body and biology.
Chinese patent publication number CN 1257847A; In open day on June 28th, 2000, name is called " process method of haydites without steaming, firing and grinding quick production of fly ash ", disclose " a kind ofly need not vapor cure, need not sintering, need not; it is a basic raw material with flyash, lime powder, terra alba with the process method of ball mill with material finely disintegrated haydites without steaming, firing and grinding quick production of fly ash such as flyash; with composite additive for attaching the raw material of helping, pass through process steps such as metering, stirring, balling-up, hot air circulate reaction finished product, saved main equipment or facilities such as ball mill, steam boiler, small-sized rotary kiln; practiced thrift facility investment; reduced energy consumption, shortened the reaction times, reduced the place to take, helped the mass industrialized production of lytag ".
The weak point of above-mentioned patent is: simple " flyash, lime powder, terra alba and the composite additive " yield rate when carrying out balling-up that adopts is lower; Because the mutual adhesive property of the raw and auxiliary material that is adopted is relatively poor; Meeting rapid solidification behind the terra alba chance water; With can not play real cohesive action after flyash and lime powder mix, but present false bonding, the haydite intensity of producing through granulating disc is low high with percentage of damage.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of unburned spheroidal attapulgite flyash haydite is provided.
Unburned spheroidal attapulgite flyash haydite is made up of attapulgite clay mine tailing, flyash, wilkinite mine tailing, stone ash and cement.
The working method of unburned spheroidal attapulgite flyash haydite: the batching of unburned spheroidal attapulgite flyash haydite is packaged as unburned spheroidal attapulgite flyash haydite after mix, granulation, maintenance and screening.
Attapulgite clay be a kind of layer of chain-like structure contain Shuifu County's zeopan clay mineral; The attapulgite clay soil property is fine and smooth; Water-absorbent is strong; Tool stickiness and plasticity-help the bonding between the raw material when wet, can improve granule strength, sticking power and the porosity of unburned spheroidal attapulgite flyash haydite.
Flyash be coal dust behind high-temp combustion, form a kind of like pozzolana mixed material, be loose porous form, can improve the granule strength and the porosity of unburned spheroidal attapulgite flyash haydite, the particle fineness of flyash≤0.15 millimeter.
Wilkinite has plasticity-and agglutinating value(of coal), is used for the granule strength that the present invention can improve unburned spheroidal attapulgite flyash haydite.
Attapulgite clay and wilkinite can mix in recovery process has a certain amount of rubble and earth; Can't sieve; Abandon as a kind of mine tailing; Cause a large amount of wastings of resources, the present invention is a mine tailing with attapulgite clay mine tailing and wilkinite mine tailing pulverize separately, particle fineness≤0.15 millimeter.
Porous basalt has sound-absorbing sound insulation, heat absorption heat accumulation, suction is anti-skidding and the characteristics of acid and alkali-resistance; The stone ash is that porous basalt is through the powder behind the crushing and screening; Being used as a kind of mine tailing mostly abandons; Can improve the intensity of unburned spheroidal attapulgite flyash haydite after stone ash and the cement mixing, grey particle fineness≤0.25 of stone millimeter.
Cement is selected the ordinary Portland cement of label >=42.5 for use.
The present invention is achieved through following technical proposals:
1, the batching of unburned spheroidal attapulgite flyash haydite is made up of following component by weight percentage: attapulgite clay mine tailing 5～25%, flyash 35～65%, wilkinite mine tailing 1～20%, stone ash 1～20% and cement 5～25%.
2, import the granulating disc granulation after the batching adding stirrer for mixing of the working method of unburned spheroidal attapulgite flyash haydite: ⑴ with unburned spheroidal attapulgite flyash haydite, particle diameter is controlled at 3～30 millimeters; ⑵ the particle after with granulation is transported to the indoor conventional maintenance of carrying out cement products of concrete pouring 28 days, through being packaged as unburned spheroidal attapulgite flyash haydite after the screening.
Screening is in order to remove the chip that unburned spheroidal attapulgite flyash haydite produces in maintenance processes.
Use the working method of unburned spheroidal attapulgite flyash haydite to produce haydite, have that balling-up speed is fast, yield rate is high, output is big, maintenance process is simple, low production cost and the characteristics that are easy to apply.
Unburned spheroidal attapulgite flyash haydite is spheroidal, and epidermis is coarse and hard, and there is trickle pore inside, is that a kind of intensity is high, thermal conductivity is low, chemicalstability good, weather resistance and the good building porcelain granule of heat preservation and soundproof performance.
The present invention fully utilizes flyash and mine tailing is produced unburned spheroidal attapulgite flyash haydite, helps improving resource utilization, turns waste into wealth, and can also reduce land occupation, and protection environment and environment purification are to achieve many things at one stroke.
Unburned spheroidal attapulgite flyash haydite is applicable to produces haydite concrete and heat-insulating and noise-insulating material.
