Abstract

Trójwarstwowa izolacja rur preizolowanych, składa się z zewnętrznej warstwy osłonowej z polietylenu wysokiej gęstości i dwóch warstw wewnętrznych. Zewnętrzna warstwa osłonowa jest wykonana z polietylenu wysokiej gęstości z dodatkiem napełniacza wybranego spośród: grafitu ekspandowanego powyżej temperatury 220°C, nanorurek węglowych, montmorylonitu, saponitu, hektorytu, krzemionki lub ich mieszanin, w ilości od 1 do 10% wag. w stosunku do masy polietylenu. Jedna z warstw wewnętrznych jest wykonana z pianki poliuretanowej z dodatkiem mikrosfer w ilości od 1 do 40% wag. w stosunku do sumy wag składników poliuretanu. Druga warstwa wewnętrzna jest wykonana z żywicy akrylowej z mikrosferami w ilości od 60 do 80% wag. Wewnętrzna warstwa z pianki poliuretanowej znajduje się pomiędzy warstwą zewnętrzną, a warstwą wewnętrzną z żywicy akrylowej.The three-layer insulation of pre-insulated pipes consists of an outer casing layer of high-density polyethylene and two inner layers. The outer casing layer is made of high-density polyethylene with the addition of a filler selected from: expanded graphite above 220 ° C, carbon nanotubes, montmorillonite, saponite, hectorite, silica or their mixtures in an amount from 1 to 10% by weight. based on the weight of polyethylene. One of the inner layers is made of polyurethane foam with the addition of microspheres in the amount of 1 to 40% by weight. based on the sum of the weights of the polyurethane components. The second inner layer is made of acrylic resin with 60 to 80 wt% microspheres. The inner layer of polyurethane foam is located between the outer layer and the inner layer of acrylic resin.
