A method includes transporting water containing chlorine dioxide, chlorine, chloramines, or hypochlorites through a pipe. The method includes forming a polyethylene resin using a catalyst, mixing the polyethylene resin with an antioxidant, wherein the antioxidant is a thioester, a hindered amine light stabilizer or 1,3,5-trimethyl-2,4,6-tris (3,5-di-tert-butyl-4-hydroxybenzyl) benzene to form a resin/antioxidant mixture, extruding pipe from the resin/antioxidant mixture, and flowing water containing chlorine dioxide, chlorine, chloramines, or hypochlorites through the pipe. An extruded article is adapted for use in containment and/or transport of water that contains chlorine dioxide, chlorine, chloramines, or hypochlorites. The extruded article includes a polyethylene resin and an antioxidant. The antioxidant is a thioester, a hindered amine light stabilizer or 1,3,5-trimethyl-2,4,6-tris (3,5-di-tert-butyl-4-hydroxybenzyl) benzene.
一种方法包括通过管道输送含有二氧化氯、氯、氯胺或次氯酸盐的水。该方法包括使用催化剂形成聚乙烯树脂,将聚乙烯树脂与抗氧化剂混合,其中抗氧化剂为硫酯、受阻胺光稳定剂或 1,3,5-三甲基-2,4,6-三(3、5-二叔丁基-4-羟基苄基)苯形成树脂/抗氧化剂混合物,用树脂/抗氧化剂混合物挤出管材,并使含有二氧化氯、氯、氯胺或次氯酸盐的水流过管材。挤压制品适用于封闭和/或运输含有二氧化氯、氯、氯胺或次氯酸盐的水。挤压制品包括聚乙烯树脂和抗氧化剂。抗氧化剂是硫酯、受阻胺光稳定剂或 1,3,5-三甲基-2,4,6-三(3,5-二叔丁基-4-羟基苄基)苯。
