PVC 线管怎么切才平整?工具与操作技巧​

2025-10-15

在装修或电气安装中,PVC线管的切割是一项基础却关键的工作。切割是否平整,直接影响后续施工质量。那PVC线管怎么切才平整呢?



首先是切割工具的选择。常见的有钢锯,它价格实惠,适合少量切割。使用时,要确保锯条安装牢固,避免晃动。还有专用的PVC线管切割刀,这种工具切割更省力、精准,切口也相对平整。另外,美工刀在一些小口径线管的简单切割中也能派上用场,但要注意安全。

操作技巧方面。用钢锯切割时,要固定好线管,防止滑动。锯割过程中保持匀速,避免用力过猛或过轻。对于切割刀,将线管放入合适的卡槽,旋转切割刀,力度均匀。若用美工刀,可先在线管上划出线,然后多次切割加深,最后折断。

切割前,还可在线管上用铅笔做好标记,确保切割长度准确。切割后,检查切口,若有毛刺,可用砂纸打磨光滑。掌握这些工具与操作技巧,就能让PVC线管切割得更平整,为后续施工打下良好基础。
