Abstract

Isoleringslegeme. Vanlige isoleringslegemer av skummede plaster, som finnes i handelen, har vanligvis en varmeledningsevne på 0,03 W(m.K) og mer. Selv for plaster som er drevet med gasser som leder varme dårlig, oppnås det sjelden bedre verdier fordi det oftest raskt inntreffer en utveksling av gass med luft. Isoleringslegemet ifølge oppfinnelsen som er fremstilt av plast som er skummet med tung gass, har derimot en forseglet overflate og får således en varmeledningsevne på mindre enn 0,02 W/(m . K) ved 20°C . Varmeisolering av apparater, beholdere, rør og bygninger.Isolation Body. Ordinary foamed plastics insulating bodies typically have a thermal conductivity of 0.03 W (m.K.) and more. Even for plastics that are fueled with gases that conduct heat poorly, better values are rarely obtained because the exchange of gas with air usually occurs quickly. In contrast, the insulating body according to the invention, made of heavy gas foamed plastic, has a sealed surface and thus has a thermal conductivity of less than 0.02 W / (m. K) at 20 ° C. Thermal insulation of appliances, containers, pipes and buildings.
