3PE防腐管道涂敷工艺参数研究与计算

2019-05-15 17:17:59

3PE防腐是现阶段应用较普遍的防腐型式之一,3PE防腐涂敷工艺参数直接影响到防腐层质量、原材料的消耗和生产速度,3PE防腐涂敷工艺参数的确定是涂敷生产的核心工作。目前管道3PE防腐涂敷工艺参数的确定基本停留在凭经验调试、修正、再调试、再修正的状况,既影响到调试的准确性,也耗费了大量时间、人工和材料。3PE防腐涂敷生产作业线,就钢管螺距、传动轮偏转角度、生产线速度、FBE喷涂参数、胶粘剂挤出机参数和聚乙烯挤出机参数的调试以及计算方法进行了研究和实践验证,推算总结出了计算公式,以期对管道3PE防腐涂敷起到指导作用。
