Abstract

Procedeul pentru prepararea unei mase de înglobare pentru pozarea subterana a conductelor de teava în special a conductelor de termoficare consta dintr-o faza de amestecare a bitumului topit cu faina de pluta dupa care se adauga pluta naturala în urmatoarea faza a carei agitare este realizata cu niste palete ce ajung la o turatie de 175-200 rot/min. Se obtine o masa de înglobare a conductelor cu o foarte buna omogenizare a plutei ce ofera stratului de pe conducte din teava metalica o foarte buna termoizolatoare.
