Abstract

Although conventional methods such as mechanical fastening, adhesive bonding and hot air welding have proven effective in dry conditions, they exhibit diminished efficacy in submerged environments. Hence, a thermoplastic welding technique with minimal dependence on surrounding media is essential. Ultrasonic spot welding (USW) represents a promising approach to thermoplastic joining, offering high efficiency and low operating costs. In this study, we investigate the efficacy of water-submerged ultrasonic spot welding (S-USW) for joining amorphous polyvinyl chloride (PVC) to PVC and semi-crystalline polypropylene (PP) to PP under submerged conditions. Our experimental results show that S-USW leads to a remarkable 39% and 21% increase in lap-shear strength for PVC/PVC and PP/PP welds, respectively, as compared to traditional USW techniques. We corroborate these findings with additional metrics such as Shore-D hardness tests, optical microscopy and scanning electron microscopy imagery, which collectively confirm the improved efficacy of S-USW over USW for joining PVC and PP.

热塑性塑料浸没式超声波点焊可行性实验研究

尽管机械紧固、粘合剂粘接和热气焊接等传统方法在干燥条件下被证明是有效的，但在浸水环境中，这些方法的效果却大打折扣。因此，必须采用一种对周围介质依赖性最小的热塑性塑料焊接技术。超声波点焊（USW）是一种很有前途的热塑性塑料焊接方法，具有效率高、运行成本低的特点。在本研究中，我们研究了水下超声点焊（S-USW）在水下条件下连接无定形聚氯乙烯（PVC）与聚氯乙烯（PVC）以及半结晶聚丙烯（PP）与聚丙烯（PP）的功效。我们的实验结果表明，与传统的 USW 技术相比，S-USW 可使 PVC/PVC 和 PP/PP 焊缝的搭接剪切强度分别显著提高 39% 和 21%。我们还通过邵氏 D 硬度测试、光学显微镜和扫描电子显微镜图像等其他指标证实了这些发现，这些指标共同证实了 S-USW 在连接 PVC 和 PP 方面比 USW 更有效。
