摘　　要：通过分析氯化钾低温转化法生产硫基NPK复合肥中转化反应槽的腐蚀状况及其原因,结合已建装置防腐衬里材料的选择,分析耐酸耐温砖、耐酸瓷砖、室温自硫化丁基橡胶等衬里性能的优劣,提出采用耐酸耐温砖+耐酸瓷砖+室温自硫化丁基橡胶的复合衬里为反应转化槽最佳防腐衬里。Through the analysis of the corrosion state and cause in the converter for production of S-NPK compound fertilizer through KCl low-temperature conversion process,and based on the selection experience of corrosion-resistant lining materials for previous projects,the pros and cons are analyzed of lining material performance including acid-and temperature-proof brick,acid-proof ceramic tile,room-temperature self-vulcanized butyl rubber,and the best corrosion-resistant lining for the converter is proposed,which is composite lining of acid-and temperature-proof brick+acid-proof ceramic tile+room-temperature self-vulcanized butyl rubber.
