Abstract

Przedmiotem zgłoszenia jest izolator termiczny oraz sposób izolacji termicznej form do prasowania tworzyw i kompozytów polimerowych, szczególnie pod dużym ciśnieniem oraz wysokiej temperaturze przetwórstwa. Izolator termiczny form do prasowania pod dużym ciśnieniem zbudowany z komory z wypełnieniem, znamienny tym, że komora zasypowa (1) o podstawie kwadratu i wymiarach w zakresie od 100 mm do 300 mmm oraz wysokości od 30 do 100 mm, z wypełnieniem (6), przy czym dolna część komory zasypowej (1) stanowi podstawa (2) w kształcie kwadratu o wymiarach od 160 mm do 360 mm, natomiast użebrowanie (4) jest zamontowane pomiędzy podstawą (2) a ścianą (3) komory zasypowej (1) w ilości od dwóch do dziesięciu sztuk na bok, przy czym grubość ścian, pokrywy i żeber wynosi od 6 do 20 mm, a całość jest połączona trwale technologią spawania, natomiast pokrywa (5) jest swobodnie umieszczona w komorze zasypowej (1) zachowując szczeliny technologiczne (7) w wielkości 1 — 2 mm, z każdej strony, przy czym komora zasypowa (1), podstawa (2), ściany (3), użebrowania (4) oraz pokrywa (5) wykonane są ze stali STRENX®1100MC do konstrukcji wymagających pracy w podwyższonych temperaturach lub obróbki cieplnej powyżej 200°C, wytrzymałość stali na rozciąganie Rm w granicach od 1250 do 1450 MPa. Sposób izolacji termicznej form do prasowania pod dużym ciśnieniem, za pomocą izolatora termicznego jak opisano znamienny tym, że stosuje się do prasowania tworzyw i kompozytów polimerowych do wartości temperatury formy 450°C i temperatury stołu prasy nie wyższej niż 50°C oraz przy nacisku do 70 ton.The subject of the application is a thermal insulator and a method of thermally insulating molds for pressing plastics and polymer composites, especially under high pressure and high processing temperature. Thermal insulator of moulds for pressing under high pressure, composed of a chamber with filling, characterized in that the charging chamber (1) has a square base and dimensions ranging from 100 mm to 300 mm and a height from 30 to 100 mm, with filling (6), wherein the lower part of the charging chamber (1) is a base (2) in the shape of a square with dimensions ranging from 160 mm to 360 mm, while the ribbing (4) is mounted between the base (2) and the wall (3) of the charging chamber (1) in the number of two to ten pieces per side, wherein the thickness of the walls, cover and ribs is from 6 to 20 mm, and the whole is permanently connected by welding, while the cover (5) is freely placed in the charging chamber (1) maintaining technological gaps (7) of 1 - 2 mm on each side, wherein the charging chamber (1), base (2), walls (3), ribbing (4) and cover (5) are made of STRENX®1100MC steel for structures requiring operation at elevated temperatures or heat treatment above 200°C, steel tensile strength Rm in the range of 1250 to 1450 MPa. The method of thermal insulation of molds for high-pressure pressing, using a thermal insulator as described, characterized in that it is used for pressing plastics and polymer composites up to a mold temperature of 450°C and a press table temperature of no more than 50°C and at a pressure of up to 70 tons.
