煤系煅烧高岭土吸油值的影响因素 总被引：1，自引：0，他引：1
涂布造纸填料用煅烧高岭土要求有较高的吸油值.本文针对市场上高吸油值煅烧高岭土资源短缺的现状,研究煅烧高岭土吸油值的影响因素,寻求提高煅烧高岭土吸油值的方法.实验以唐山煤系高岭土为原料,在600～1000℃范围内间隔50℃取点,分别煅烧3h.采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)观察煅烧高岭土的形貌并鉴定其物相.计算煅烧高岭土的烧失量,并检测其pH值、比表面积、Zeta电位等参数,分析它们对煅烧高岭土的吸油值的影响.结果表明:750℃煅烧的高岭土吸油值最高,可达76.3 g/100 g;煅烧高岭土的Zeta电位、pH值、比表面积等对其吸油值的影响均较为显著,其中比表面积对吸油值的影响最大. 相似文献

Starting from general considerations of the rocks existing in the Ruhr Carboniferous and the mineral layers in coal seams, an informative review is given about the definition of clay stones and kaolin coal tonsteins as well as about the stratigraphic distribution of key horizons with special regard to the kaolin coal tonsteins. Information follows about the first evidence of individual kaolin coal tonsteins, their existence in the normal geologic columns and more recent stratigraphic sections as well as about the concentration of repositories. Besides, the kaolin coal tonsteins are characterized according to their macroscopic and microscopic external form. The paper reports about their material constituents (mineral components, trace elements, anorganic chemical constituents and organic substances in form of coal hydrates and amino acids). The paper closes with some statements about the importance and utilization of kaolin coal tonsteins to solve local and regional duties in mining geology. 相似文献

高岭土的深加工与新材料 总被引：6，自引：1，他引：6
煅烧高岭土由于晶体结构的改变而引起理化性能的变化，所表现出的性能更加优异。利用高岭土的特殊层状结构，将一些强极性有机小分子插入到结构层间，生成有机插层材料，这种新的复合物将黏土矿物和有机化合物的各自特性有机结合，极大地开阔了高岭土的应用领域和“档次”。以高岭土为原料而开发成功的Sialon材料，由于所具备的优越的力学性能、高温性能及化学稳定性等，在冶金、航空、化工机械和药学等方面显现出了极好的应用前景。地聚物材料是以偏高岭土、碱激发剂为主要原料，具有与陶瓷性能相似的一种新材料。 相似文献

The South Ushkoty eluvial kaolin deposit discovered and explored by the authors is situated 20 km away from the railway in the Dombarov district of the Orenburg region. The deposit is localized in the axial zone of the East Ural Uplift. Leucogranites of the Upper Ushkoty Pluton serve as bedrocks. The deposit comprises five lodes, among which the largest deposit has a reserve of 40 Mt. The lodes are erosion remnants of the well-developed linear-areal weathering zone related to the fragments of Mesozoic peneplain at the hypsometric level not lower than 360 m. Variation of the kaolin zone thickness, the entire weathering zone, and the deposit morphology is largely governed by the nearly meridional and northeastern faults. Two productive zones—the normal kaolin (kaolinite + quartz) zone and the alkaline kaolin (kaolinite + quartz + potassium feldspar and/or muscovite) zones—are recognized in the weathering profile of leucogranites of the Upper Ushkoty Pluton. The alkaline kaolin is of commercial significance as a complex raw material if the potassium oxide content is above 3.5%. The composition and properties of the concentrated kaolin meet the requirements of its traditional consumers (fine ceramic works, paper mills, and others). The discovery of the South Ushkoty deposit confirmed the previous forecast on considerable prospects of the Orsk Transural region for kaolin. We hope that this discovery will stimulate the further investigation and assessment of resources in the Mugodzhary kaolin-bearing subprovince. 相似文献

The Zhuravlinyi Log deposit is located 12 km southeast of Plast City. The deposit was initially prospected in 1951 and 1952
under the supervision of V.G. Lyulicheva. The prospecting revealed the presence of kaolin of quality surpassing the raw material
in the Eleninsk and Kyshtym deposits. Although a positive assessment was given, new prospecting and appraisal works were carried
out under the supervision of V.I. Kakorin in the vicinity of the previously discovered deposit in 1985 taking into consideration
recommendations given by the VNIIgeolnerud (renamed TsNIIgeolnerud) Federal State Unitary Enterprise. The results revealed
several separate white and pale kaolin deposits. Exploitation of the deposit was started even before its exploration. Construction
of the Plast-Rifey dressing plant was completed during the exploitation of the central ore body. Follow-up exploration of
the deposit completed in 2006 confirmed that the dry kaolin equivalent reserves of categories B + C1 according to the Russian classification (approximately corresponding to the measured + indicated reserve in the western classification)
and category C2 (approximately corresponding to the inferred reserve) are estimated at 11.05 and 5.55 Mt, respectively. The Zhuravlinyi Log
deposit is a major supplier of kaolin products fitting the standards of paper, fine ceramics, fiberglass, chemical reagents,
and others. The present paper based on the exploration data attempts to show specific features of the geological setting of
this deposit, as well as the mineral composition and properties of kaolin therein. 相似文献
