Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania elementów termoizolacyjnych ze spienionego polistyrenu, w którym surowiec w postaci granulek polistyrenu poddaje się procesowi wstępnego podgrzewania w temperaturze od 35 do 55°C w czasie od 30 do 90 sekund, przy czym proces wstępnego podgrzewania odbywa się w dozowniku ślimakowym z wykorzystaniem energii cieplnej odzyskanej w procesie spieniania, następnie wstępnie podgrzany surowiec poddaje się procesowi spieniania, następnie spieniony surowiec poddaje się procesowi sezonowania w stałej temperaturze od 30 do 50°C w czasie od 4 do 8 godzin, przy czym proces sezonowania odbywa się z wykorzystaniem energii cieplnej odzyskanej w procesie formowania w blok, następnie wysezonowany surowiec poddaje się procesowi formowania w blok, przy czym do surowca dodaje się od 1 do 3% wagowych ekspandowanego granulatu szklanego o wielkości ziarna od 0,04 do 0,125 mm, a w końcowym etapie formowania w blok surowiec poddaje się działaniu podciśnienia powietrza, a następnie nadciśnienia powietrza lub gazu obojętnego w zakresie od 0,3 do 0,6 bar w czasie od 30 do 90 sekund, a następnie uformowany blok surowca poddaje się procesowi sezonowania w temperaturze od 10 do 40°C w czasie od 36 do 60 godzin, korzystnie 48. Element termoizolacyjny ze spienionego polistyrenu, w którym poziom odchyleń gęstości w jednostce masy wynosi +0,1/-0,1 kg/m3, zawierający od 1 do 3% wagowych ekspandowanego granulatu szklanego o wielkości ziarna od 0,04 do 0,125 mm.The subject of the application is a method of producing thermal insulation elements from expanded polystyrene, in which the raw material in the form of polystyrene granules is subjected to a pre-heating process at a temperature from 35 to 55 ° C for 30 to 90 seconds, with the pre-heating process taking place in a screw dispenser using heat energy recovered in the foaming process, then the preheated raw material is subjected to the foaming process, then the foamed raw material is subjected to the seasoning process at a constant temperature of 30 to 50 ° C for 4 to 8 hours, with the seasoning process being carried out using energy heat recovered in the block forming process, then the seasoned raw material is subjected to the block forming process, with 1 to 3% by weight of expanded glass granulate with a grain size from 0.04 to 0.125 mm added to the raw material, and in the final stage of forming into a block the raw material is put to work air underpressure followed by overpressure of air or inert gas in the range of 0.3 to 0.6 bar for 30 to 90 seconds, and then the formed block of raw material is subjected to the seasoning process at a temperature of 10 to 40 ° C for 36 to 60 hours, preferably 48. A thermal insulating element made of expanded polystyrene, in which the level of density deviations in the mass unit is + 0.1 / -0.1 kg / m3, containing from 1 to 3% by weight of expanded glass granulate with a grain size of 0.04 to 0.125 mm.
