Description
Technical field
The present invention relates to a kind of waste material that utilizes and prepare method of ceramic material, particularly a kind of method of utilizing rejected fly ash to prepare haydite.
Background technology
Haydite is the needs for adaptation modern architecture lightness, high performance, and by the new concrete light-weight aggregate of the general Application and Development in countries in the world.According to the difference of raw material, it can be divided into leca, lytag and haydites of book structure.Lytag has light weight, insulation, sound insulation, heat insulation, freeze proof, advantage such as intensity is big, water-intake rate is low, can be used as building masonry infill, heat insulating refractory materials, filtering material, sound absorbent material etc., instead of clay haydite and haydites of book structure, have energy-conservation, characteristics (Yu Minfeng such as profit is useless, environmental protection, Wang Shijie, king's roller etc. the popularization of the new way of total utilization of PCA-lytag production technology and application [J]. Chinese comprehensive utilization of resources, 2006,24 (11): 11-12).
In recent years, along with the in-depth of flyash Studies of Comprehensive Application and the develop rapidly of oil exploration industry, lytag is applied in the petroleum drilling operation as fracturing propping agents, make oil, gas well output improve several times to tens times, replace conventional quartz sand propping agent gradually, become the proprietary material of Shallow Oil-Gas field pressure break exploitation.But at present, the oil-gas field major part belongs to moderate depth, requires fracturing propping agents to have high strength, low percentage of damage, to bear the various corrosion in huge pressure in rock stratum and the ground environment.In the world more adopt the alundum goods as in, deep-seated oil gas field fracturing propping agents, though this goods can meet the demands on physicochemical property, but raw material sources difficulty, the complete processing complexity, and energy consumption is big, cost is high, makes its application be restricted (Gao Haili, the trip talent, Wu Hongxiang etc. the development of high-strength petroleum fracturing propping agent [J]. Flos Bombacis Malabarici science and technology and information, 2006,31 (4): 19-20).
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of method of utilizing rejected fly ash to prepare haydite is provided.Not only raw material sources are extensive, production cost is low for this method, energy consumption is little, and turn waste into wealth, and can produce high-strength compress supporting agent for coarse oil, in, the deep layer oil-gas field fracturing provides the fracturing material of better performances.
For achieving the above object, the technical solution used in the present invention is:
