摘要
对管道堵塞疏通剂（简称疏通剂）进行了模拟应用及下水道常用配件的腐蚀和稳定性试验．结果显示：（１）在模拟应用试验中疏通剂与堵塞物加水反应３０ｍｉｎ后，管道内无堵塞残留物存在；（２）稳定性试验的测定数据经Ｖａｎ’ｔＨｏｆ经验规则计算公式推算出疏通剂在２５℃条件下储藏保质期至少在１年以上；（３）腐蚀试验（重量法）测定的ＰＶＣ塑料管和铸铁管腐蚀前和经疏通剂腐蚀６ｈ后所得数据经ｔ－检验统计无显著性意义〔Ｐ（概率）＞０．０５〕．
The simulated appling, corrodentia of drain fittings and stability test of drain pipes block opener agent (opener agent) were studied. Data from determination showed: (1) No blocken-matter remained after putting opener agent and water in pipes for 30 min from simulated appling test; (2) The opener agent was in storege guarautee quality more than 1 year in the 25℃, date from determination of stability test with Van't Hoff experience requlations formula; (3) Date from PVC plastic and cast iron pipes both before and after corrodetia with adding the opener agent (lasted 6 hours) was not significant difference to weight method determination ( P >0.05).
