植物纤维增强水泥管耐强酸强碱腐蚀研究

市政排水管道常用水泥管或钢筋混凝土管作为主要管材,市政污水可能会对管道造成腐蚀。研究了植物纤维增强水泥管在pH值为1、2、3、14的溶液中浸泡一个月的腐蚀情况,通过表观观测、质量和抗压强度测定,以耐蚀系数和质量损失率两个指标判定植物纤维增强水泥管在试验条件下的腐蚀情况。结果表明,植物纤维增强水泥管在强酸强碱溶液中浸泡一个月,质量和抗压强度均无明显损失,其耐久性有一定的保障,可以用作市政排水管道建设。

Study on Resistance of Plant Fiber Reinforced Cement Pipe to Strong Acid and Alkali Corrosion

The municipal drainage pipe is commonly used as the cement pipe or reinforced concrete pipe as the main pipe material.The municipal sewage may corrode the pipes.The corrosion situation of the plant fiber reinforced cement pipe soaked in a solution with the pH value of 1,2,3,and 14 for one month is studied.By the apparent observation,quality and compressive strength measurement,two indexes of anti-corrosion coefficient and mass loss rate are used to determine the corrosion situation of plant fiber reinforced cement pipe under the test condition.The results show that the quality and compressive strength of plant fiber reinforced cement pipe soaked in a solution with strong acid and alkali for one month have no significant loss,and its durability has a certain guarantee.This kind of pipe can be used in the construction of municipal drainage pipeline.
