喷瓷管道用玻璃釉料润湿行为的研究

/ WETTING BEHAVIOUR OF CLASS GLAZE MATERIAL OF SPRAYED PORCELAIN PIPE

采用扫描电镜（ＳＥＭ）和Ｘ射线能谱分析（ＥＤＳ）等手段，研究了喷瓷管道用玻璃釉料对碳钢基体的润湿行为。研究结果表明，底釉的润湿面积随着温度的升高和恒温时间的延长而增大，在一定的温度和时间下达到最大值。增加基体表面粗糙度和减小面釉在底釉中的含量，可促进润湿性的改善。基体金属进入界面过渡层以及界面过渡层富集密着剂都有利于釉料润湿基体。

The wetting behaviour of glass glaze material of sprayed porcelain pipe on the plain steel was analyzed with a scanning electron microscope (SEM) equipped with an energy dispersive spectrum (EDS) analysis system. The results indicate that the wetting area of priming glaze will enlarge with increasing temperature and insulation time, and achieve the greatest value at 900 ℃ and insulation time of 1000 seconds. The wetting performance can be improved with the increase of surface roughness of base metal or with the decrease of the content of overglaze in priming glaze. The entry of base metal and the enrichment of indiscrete dosage in the intermediate layer can also be effective to the wetting performance.
