摘　　要：针对沟槽式管接件行业传统的水性丙烯酸浸漆工艺只采用高黏度漆液浸渍一遍成膜后在高温烘烤时出现的流坠、爆泡等问题,开发了一种新的施工工艺并付诸实践。该工艺采用低黏度漆液浸渍一遍,闪蒸过程中在合适位置刷去流坠,然后进入低温区强制水分挥发,再喷补、流平之后进入高温烘烤区。既确保了整个工件的漆膜厚度,又很好地解决了传统工艺的通病,在发挥了水性浸漆设备投资少、操作简单的优势的同时,还保证了漆膜外观效果,提升了防腐性能。A new process for water-based acrylic immersion painting of grooved pipe fittings was developed and applied to solve the problems(e.g.sagging and bubbling)of the traditional process in which the coating is formed by dipping in high-viscosity paint only once and baked at high temperature.There are several steps in the new process:(1)dip in low-viscosity paint;(2)brush the sags away during flash evaporation;(3)volatilize water in low-temperature baking section;(4)spray for repairing;and(5)bake at high temperature after leveling.The process not only ensures the coating thickness of the entire workpiece,but also solve the problems occurred in traditional technology.Some other advantages of the process are achieved:less equipment cost,simple operation,good coating appearance,and improved anticorrosion performance.
