Abstract

Предлагается способ изоляции труб путем нанесения реакционной смеси ароматического полиизоцианата, органического соединения с мол.м. 92 - 1000, имеющего в среднем по меньшей мере три реакционноспособных относительно изоцианатов атома водорода, алифатического, циклоалифатического или проматического полиамина и/или полиимина с мол.м. 32 - 1000 в качестве сшивающего агента и вспенивающего агента, служащей для выполнения по меньшей мере одного изоляционного слоя жесткого пенопласта и в случае необходимости дополнительной реакционной смеси для выполнения покровного слоя на вращающуюся трубу, который заключается в том, что на вращающуюся трубу наносят реакционную смесь для выполнения изоляционного слоя жесткого пенопласта, содержащую имеющее мол. м. 32 - 1000 соединение общей формулы I или II, приведенных в описании.
