摘要
近年来,石墨防腐设备已逐渐应用于氯碱工业、磷酸盐、磷肥工业、氟化工等领域的氢氟酸生产。目前的主要应用石墨设备包括:石墨热交换器、石墨冷凝器、钢衬石墨反应釜、钢衬石墨反应槽、集中器、反应塔、填料塔和磷酸萃取槽,造粒塔和其他高温反应设备、换热设备、冷却设备、防腐衬里防腐设备。通过一个过滤器的热还原与转移办法实现了新型的石墨薄膜,实验结果表明,采用的转移方法可以实现一致性良好、可控制厚度的薄膜。
In recent years, the graphite anticorrosion equipment has been applied to the production of hydrofluoric acid in chlor-alkali, phosphate, phosphate fertilizer and fluorine chemical industries. At present, main graphite equipments include： graphite heat exchanger, graphite condenser, steel lining graphite reaction kettle, steel lining graphite reaction tank, concentrator, reaction tower, packed tower and phosphoric acid extraction tank, prilling tower and other high temperature reaction equipments, heat exchange equipments, cooling equipments, anti-corrosion lining anticorrosive equipments. In this paper, a new type of graphene film was prepared by thermal reduction and transfer method in a filter. The experimental results showed that the transfer method could be used to prepare graphene film with good consistency and controllable thickness.
