Description

With haydite of resinous shale preparation and preparation method thereof
Technical field
The present invention relates to light skeletal used in the building trade---haydite, particularly haydite and preparation method thereof.
Background technology
Resinous shale is by the organic formation of deposits simultaneously of fine mineral chip and lower animal and plant residue decomposition, be that a kind of ash-rich is (greater than 33%, the ash of coal is less than 33%) can the organic rock of incendiary, elementary composition by carbon, hydrogen, oxygen, nitrogen, sulphur etc.Organic matter is formed through gelification by unicellular lower eukaryote remains such as algae.That its color has is greyish white, yellowish-brown, brown, grey black and black etc. multiple, and the general color shallow oil length of healing is higher.General organic content is just having industrial value more than 5%.Oil length and thermal value are to estimate the important technical index of oil shale industry purposes.In the world oil length per ton is called resinous shale greater than the shale of 0.25 barrel (being equivalent to oil length more than 3.5%).Resinous shale can directly burn, and is used for generating.Resinous shale can obtain a series of industrial chemicals such as gasoline, diesel oil, kerosene, lubricating oil, paraffin, pitch, ammoniacal liquor, sulphurized asphalt through low-temperature pyrolysis.
The development and use of resinous shale have had the history in 200 years.From 1839, the exploitation beginning of French Autun resinous shale mineral deposit, to the thirties in 20th century, world's resinous shale annual production has reached 5 * 106t; The forties, the resinous shale annual production obviously descended owing to the influence of World War II; 1945-1980, the world energy sources crisis has especially appearred the seventies, each state is all for seeking new energy effort, the numerous and confused research of country such as the U.S., Japan, Brazil, Estonia, the former Soviet Union makes the resinous shale utilization ratio be the trend of quick growth from the combustion technology and the retorting technique of resinous shale; After 1980, because oil is found in a large number and developed, oil price declines to a great extent, and it is higher that resinous shale refines the shale oil cost in addition, causes the annual production of resinous shale to descend.In the 50-60 age in 20th century, resinous shale once was a kind of main hydrocarbon resources of China.Before finding Daqing oil field, the oil of China 3/4 is from resinous shale.Found Daqing oil field the sixties, oil is progressively realized self-sufficiency, and resinous shale lies on the table gradually.Therefore, remain to seek a new resource utilization method into resinous shale.
Summary of the invention
Technical problem to be solved by this invention is: a kind of haydite with resinous shale preparation and preparation method thereof is provided, and the present invention can make full use of mineralogical composition and the combustiblecomponents in the resinous shale, the haydite high strength of making.

The material chemical component scope (%) of suitable sintering-expanded haydite is SiO 2: Al 53%～79%, 2O 3: Fe 10%～25%, 2O 3, K 2O, Na 2Flux sums 13%～26% such as O, CaO, MgO.On chemical ingredients, resinous shale satisfies above requirement.Resinous shale mainly by kaolinite and quartzy the composition, contains a spot of alkaline earth metal oxide, belongs to clay mineral., therefore, cooperate through proper raw material, can burn out the haydite that meets the demands.
Product performance are analyzed:
Above embodiment 1-10 all can prepare the haydite that complies with the national standard requirements.
TFe in the common raw material 2O 3Content just can satisfy the requirement that haydite burn to expand 6～10%.In embodiment 1-3, TFe in the compound 2O 3Content less than 4.41%, the haydite swelling rate is lower, is unsuitable for as light ceramic.The reduction of total iron content has also caused 30-50 ℃ of firing temperature rising.In these three embodiment, the addition content of resinous shale is 20～40%, and addition content is lower, does not meet the principle of utilizing resinous shale in a large number.In embodiment 9-10, the addition content of resinous shale reaches more than 95%.Contain organic composition in the resinous shale, though organic composition is favourable to the expansion of haydite in the sintering process, too high organic content can improve the burning mistake rate of haydite, to such an extent as to make the haydite cracking in sintering process, influences the intensity of final product.Embodiment 4-8, the silica alumina ratio in the compound is suitable, contains enough flux components again, between 1100-1200 ℃, can burn out the light high-strength haydite that meets standard GB 2839-81 (leca and pottery sand) specification of quality.Embodiment 4-8 is an optimum implementation, and its technical process as shown in Figure 1.
From market value, with the clay is main raw material, set up a cover haydite production line, annual production 2.5 ten thousand stere haydites, 38 yuan of every square metre of cost costs, totally 95 ten thousand yuan of annual cost estimatings, minimum 95 yuan every cubic metre of selling prices in Beijing, annual output should be (65 yuan every cubic metre of factory price estimations) 162.5 ten thousand yuan, and the budget profit is 162.5 ten thousand yuan-950,000 yuan=67.5 ten thousand yuan.From producing originally, the production of haydite at present mostly with high-quality, high-grade clay and ore product as raw material, cause cost higher, rate of profit is difficult to improve again.It is then different to adopt resinous shale to prepare haydite, can gather materials on the spot, a large amount of conservation transportations and buying expenses.As seen utilizing the resinous shale baking ceramsite is to reduce production costs, a shortcut of increasing economic efficiency, and its market competitiveness is self-evident.
