高密度聚乙烯管内壁电晕处理技术要点

Technical Key Points for Corona Treatment of High Density Polyethylene Pipe Inner Wall

高密度聚乙烯管内壁电晕处理对提高聚氨酯保温材料与高密度聚乙烯管内壁的粘接能力有所帮助。从电晕处理程度(由输出电压、放电频率表征)、电极间隙等方面,对电晕处理的技术要点进行探讨。介绍电晕质量检测方法。

Corona treatment of high density poly- ethylene pipe inner wall is helpful to improve the adhe- sive force of polyurethane insulation material and high density polyethylene pipe inner wall. The technical key points of corona treatment are discussed in terms of the corona treatment degree characterized by output voltage and discharge frequency, electrode gap and so on. The corona quality testing method is introduced.
