Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania termoplastycznej kompozycji polietylenowej, który charakteryzuje się tym, że umieszcza się w pojemniku mikrokulki szklane o granulacji od 250 µm do 630 µm w ilości od 10% do 15% wagowo składu kompozycji, po czym zalewa się mikrokulki szklane acetonem technicznym w proporcji 1:1,6. Następnie potrząsa się pojemnikiem w czasie od 90 s do 180 s z częstotliwością od 2 Hz do 3 Hz, po czym suspensję umieszcza się na sicie o oczkach o wielkości od 220 µm do 250 µm pod wyciągiem mechanicznym na czas 24 h do pełnego odparowania acetonu technicznego. Następnie do mieszalnika planetarnego z dozownikiem grawimetrycznym wprowadza się uprzednio przygotowane mikrokulki szklane oraz polietylen typu LLDPE w ilości od 85% do 90% wagowo składu kompozycji, po czym całość miesza się mieszadłem planetarnym z prędkością 25 obr./min. Następnie mieszaninę podaje się do leja zasypowego układu uplastyczniającego wytłaczarki dwuślimakowej, po czym nagrzewa się mieszaninę w strefie pierwszej do temperatury 150°C, w strefie drugiej do temperatury 160°C, w strefie trzeciej do temperatury 165°C, w strefie czwartej do temperatury 170°C, w strefie piątej do temperatury 173°C, a w strefie szóstej do temperatury 175°C i wytłacza się mieszaninę przez głowicę granulacyjną wytłaczarki z jedną strefą grzejną o temperaturze 175°C przy obrotach ślimaka 1,75 s-1. Następnie chłodzi się wytłoczynę w płaszczu wodnym o temperaturze 55°C, po czym wprowadza się do głowicy tnącej i rozdrabnia się do postaci granulatu.The subject of the application is a method for producing a thermoplastic polyethylene composition, which is characterized in that glass microspheres with a granulation of 250 µm to 630 µm are placed in a container in an amount of 10% to 15% by weight of the composition, and then technical acetone is poured over the glass microspheres in a ratio of 1:1.6. The container is then shaken for 90 s to 180 s at a frequency of 2 Hz to 3 Hz, after which the suspension is placed on a sieve with mesh sizes of 220 µm to 250 µm under a mechanical fume hood for 24 hours until the technical acetone is completely evaporated. Next, previously prepared glass microspheres and LLDPE polyethylene are introduced into a planetary mixer with a gravimetric feeder in an amount of 85% to 90% by weight of the composition, and the entire mixture is mixed with a planetary mixer at a speed of 25 rpm. The mixture is then fed to the hopper of the plasticizing system of the twin-screw extruder, after which the mixture is heated in the first zone to a temperature of 150°C, in the second zone to a temperature of 160°C, in the third zone to a temperature of 165°C, in the fourth zone to a temperature of 170°C, in the fifth zone to a temperature of 173°C, and in the sixth zone to a temperature of 175°C. The mixture is extruded through the granulation head of the extruder with one heating zone at a temperature of 175°C at a screw speed of 1.75 s-1. The extrudate is then cooled in a water jacket at 55°C, then fed to the cutting head and crushed into granules.
