聚乙烯经辐照交联处理后,耐腐蚀性、耐热性、强度等都有显著的提高,并具有记忆效应。因此,辐照交联聚乙烯包覆或内衬用于碳钢管防腐目的是很吸引人的。我们对经γ辐照交联后的聚乙烯材料的机械强度、凝胶量和熔融指数的变化进行了检测研究。求得了合适的交联工艺和辐照剂量。我们根据防腐工艺要求研制了专用的聚乙烯包覆管 Polyethylene by radiation crosslinking treatment, corrosion resistance, heat resistance, strength, etc. have significantly improved, and has a memory effect. Therefore, the irradiation of cross-linked polyethylene coated or lining for carbon steel pipe corrosion purposes is very attractive. We examined the changes in the mechanical strength, gel content, and melt index of the polyethylene material crosslinked by gamma irradiation. Obtained a suitable cross-linking process and irradiation dose. We developed a special polyethylene coated pipe according to the requirements of anti-corrosion process
