Метод определения долговечности изоляции из жесткого пенополиуретана для предварительно термоизолированных труб

Метод определения долговечности изоляции из жесткого пенополиуретана для предварительно термоизолированных труб

Abstract

Разработана экспресс-методика, позволяющая с высокой точностью оценивать долговечность пенополиуретановой теплоизоляции, которая будет равна долговечности этого же образца, полученной при длительных стендовых испытаниях по методикам, используемым в PAN-ISOVIT и НИИМОССТРОЙ. Определен контрольный показатель качества ППУ, который установлен на уровне значения Е равного 112 кДж/моль и обеспечивающего долговечность теплоизоляции в 20 лет при переменном температурном графике работы тепловых сетей для среднеевропейской зоны.
