双孔径新型橡塑保温管及其制造工艺
技术领域
本发明涉及橡塑管材技术领域,具体为双孔径新型橡塑保温管及其制造工艺。
背景技术
橡塑发泡保温产品是一类高阻燃且保温等各项性能都非常优异的产品,因而其在市场上越来越受到青睐,但是因其已高度硫化,废料难以通过生物降解进行处理,目前也有部分厂商会对一部分的橡塑产品进行回收,回收的橡塑产品能够作为添加剂来生产新的产品,以降低生产成本,但是受到市场需求和自身产能的影响,回收再利用的量平均只能占橡塑产品生产量的10%-20%,而大部分的橡塑产品无法被回收,一般通过填埋或焚烧进行处理,造成了严重的环境污染,为此,提出一种能够能够被生物降解的且能够部分回收满足生产需要的双孔径新型橡塑保温管。
