Unverified液体强碱型（如管道疏通液）比重大于水，能下沉穿过积水直达堵塞点，是有少量积水但未完全堵死场景的首选剂型81% similarUnverified颗粒型用量大、需配合热水（非沸水）激活，适合彻底堵死；凝胶/液体型能穿透积水直达堵点，适合有存水的地漏81% 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79% 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79% 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79% similar
