Description
Technical field
The present invention relates to a kind of is the crystallite foam glass and the manufacture method of main raw material preparation with the kerosene shale ash.
Background technology
Crystallite foam glass is a kind of novel multifunctional material.Be mainly used in the bearing wall of (1) buildings; (2) cryogenic piping, equipment, container and storage tank; (3) deep fat and heated bitumen storage tank; (4) petrochemical complex, sulfuration production process; (5) fluid heat-exchange system; (6) extensive fields such as the sound insulation of compressor, Ventilator Room and sound-absorbing wall.
Crystallite foam glass be a kind of be main raw material with cullet, flyash, nonmetalliferous ore etc., add whipping agent, nucleator and admixture etc., mix the formation admixtion after crushed, then admixtion is put in the mould and in electric furnace, heats, through preheating, sintering, foaming, surely steep and novel porous microcrystal glass material that technology such as annealing is made.
Since the general multicellular glass height of strength ratio of crystallite foam glass, the advantage that the volume to weight ratio devitrified glass is little.In recent years, selection, performance, application and the blowing temperature of the preparation technology of crystallite foam glass, raw material are determined etc. that all there is research the aspect.Chen Kerong etc. have prepared foamed glass ceramic material for wall with glass powder, flyash and nonmetalliferous ore; Wang Lijius etc. are basic material with cullet and light ceramic, have prepared novel crystallite foam glass material; Guo Hongwei etc. are main raw material with the cullet, as whipping agent, as nucleator, have prepared crystallite foam glass with Vanadium Pentoxide in FLAKES with carbon dust.Above technological line all is to be main raw material with the cullet, and is less relatively to the utilization ratio of non-metallic minerals.
Resinous shale is the organic mineral products of a kind of high-ash solid combustible.China's resinous shale finds out that stock number is 329.89 hundred million t, occupies the 4th in the world, mainly is distributed in northeast and ALFISOL IN CENTRAL.Refine a large amount of lime-ash of meeting generation in shale oil and the oil shale combustion process at resinous shale, need take a large amount of soils and cause problems such as serious environmental pollution, therefore how improving the comprehensive utilization ratio of resinous shale lime-ash, improve the added value of oil shale resources, is the technical problem that needs to be resolved hurrily.
