42、自行式楔焊机（热合机）是二十世纪后期研制出的焊接高分子合成材料的新型设备。其基本原理是通过一个电热楔给搭接的两层材料从中间加热，再经过具有一定压力的滚轮压合，使两层材料熔融、结合成一体。自行式楔焊机（热合机）能一次完成一组双焊缝，并形成一个可充气捡漏的空腔，在设备参数调定后，焊机将自行完成焊接工作。它有很好的控制系统，以保证焊接质量，大大减少了人为操作技艺的影响。它使焊缝的捡漏方波由真空改进成充气法，极大的提高了工作效率。2、自动挤压焊机挤压熔焊机是在HDPE 防渗膜焊接中长期使用的专用设备。在九十年代，楔焊机得到了广泛应用以后，在大面积焊接中，它已被取代，但仍然是HDPE 防渗膜焊接中必不可

43、少的生产设备。对于非直接搭接的部分以及局部补修、加强等部位的处理，都必需应用挤压熔焊机。挤压熔焊机的基本原理是将送入的与膜同质的焊条切碎、熔融，然后挤出在两幅膜的接缝上。使三者熔合为一体。有温控器直接控制加热系统，确保熔融的温度总处于最佳的状态。本工程因采文档编码:CC1H5B2N2T5 HO8I7Q9F1L6 ZO6T5H3T9U10文档编码:CC1H5B2N2T5 HO8I7Q9F1L6 ZO6T5H3T9U10文档编码:CC1H5B2N2T5 HO8I7Q9F1L6 ZO6T5H3T9U10文档编码:CC1H5B2N2T5 HO8I7Q9F1L6 ZO6T5H3T9U10文档编码:CC1
