Evaluation of Aggressive Chemicals Effect on CIPP Liners

Popis výsledku v původním jazyce

CIPP renovation methods are often used for renovation of sewers and water mains. They can also be used for renovation of gas and product pipelines. However, the presence of chemicals in these pipelines cannot be excluded. For this reason, the ability of CIPP liners to resist chemicals should be examined. This paper deals with problematics of influence of chemicals (acids and bases) on CIPP liners. Visual changes can be observed using an optical microscope. Structural changes are evident from the results of short-term bending tests. During the visual observation, no visible changes in the structure of the samples were found. Exposure of the samples to the 20% hydrochloric acid caused damage of the polyurethane membrane. The polypropylene membrane remained unchanged. The decrease in flexural modulus was most noticeable with samples stored in 10% ammonium hydroxide.
