Unverified颗粒型比液体型碱浓度高、更适合有积水的下水道（颗粒能沉降到堵塞处放热），液体型适合无积水的管壁油污87% similarUnverified固体颗粒/粉剂疏通剂需配足量水激活反应，适合完全堵死的管道（能沉底到堵塞处）；液体型适合半堵水流缓慢的情况，遇积水会被稀释失效86% similarUnverified已完全堵死、管内积满水的情况下慎倒固体强碱颗粒，颗粒沉底后与水放热但难以下渗到堵点，效果差且积水强碱溅出风险高；完全堵死优先物理疏通（皮搋子/管道弹簧）再化学养护84% similarUnverified采用牛津布材质，具备基本防泼水性能，但不等同于防水，液体泡浸或大量渗水场景下仍会渗透。84% similarUnverified完全堵死无法排水（积水静止）时优先选固体颗粒/粉剂，因颗粒可沉降穿透积水到达堵塞点；液体剂在深积水中会被稀释失效84% similar
