Compatibility Testing of High Density Polyethylene (HDPE) for Use as a SecondaryContainment Liner for a Mixed Nitrating Acid Storage Tank Farm

摘要

The use of high density polyethylene (HDPE) as a secondary containment liner fora mixed nitrating acid storage tank facility was investigated. The chemical resistance and compatibility of HDPE with mixed nitrating acids (mixtures of nitric acid and sulfuric acid) was of primary concern. Weight, volume, specific gravity, and tensile properties of the polymer were used to evaluate the chemical resistance. Samples were immersed directly in various concentrations of mixed acid while cycling the temperature between hot and cold extremes. jg p.2.
