| 摘 要： | 通过XRD分析可知：窑尾上升烟道2号结皮JPS2含有相当数量的CaSO4,CaSO4颗粒是导致这个区域结皮的主要物质;上升烟道6号结皮JPS6中的硫酸盐存在形式由熔点较高的CaSO4向熔点较低的R2SO4过渡;引起窑列C5结皮JPA5的活跃组分由硫变成了氯,碱的主要存在形式也由硫酸盐形式转为氯盐形式;形成炉列C2结皮JPB2的黏结力主要体现为表面力,即范德华力、静电力及高的比表面能等。

| Abstract: | The XRD analysis results showed that the coating of JPS2 contained a considerable amount of CaSO4,and this CaSO4 particles caused the formation of crust in this region.The state of CaSO4 with higher melting point transited to R2SO4 with lower melting point in JPS6.The active components that caused coating in 5th stage in kiln-series was chlorine instead of sulfur,and the main existing forms of alkali in JPA5 changed from sulfate to chloride.The bond force of JPB2 coating was mainly surface-force(Van der Waa... |
