| 摘要： | Geosynthetics testing company ExcelPlas in Highett, Australia, has identified two alternative stress-cracking surfactants for high-density polyethylene (HDPE) geomembranes. Igepal CO-630 (octyl-phenoxypolyethoxyethanol), the non-ionic surfactant used in HDPE stress-cracking bath, is becoming harder to purchase with restricted supply in many countries because it can cause long-lasting harmful effects to aquatic life. The ASTM D5397 single-point, notched constant tensile load (SP-NCTL) test for assessing the stress cracking resistance (SCR) of HDPE geomembranes specifies that the detergent (surfactant) to be used in the stress-cracking baths is Igepal CO-630. However, the European Union (EU) and Canada classify Igepal CO-630 as a priority pollutant. ExcelPlas researched alternative stress cracking surfactants for the SP-NCTL SCR test. It has found the following two detergents to be potential replacement options: 1. Arkopal N-100 from Clariant Produkte (Deutschland) GmbH 2. Dehyton PL from BASF based on lauramine oxide. |
