Abstract
Sposób wytwarzania recyklatu w formie płatków kompozytowych w typowym urządzeniu w którym formowana jest wstęga z odciętych skrajnych fragmentów membrany gdzie można przerabiać jednocześnie kilka wstęg charakteryzuje się tym, że następuje chwilowe rozgrzanie wstęgi w komorze o temperaturze o 30°C do 40°C wyższej od temperatury topnienia głównego składnika polimerowego, a następnie specjalne rolki (grawerowane) zgniatają kilka otrzymanych wstęg odpadu do taśmy, której grubość można regulować poprzez ustawienie wielkości kanału wlotowego, po czym taśma ta jest cięta nożem krążkowym typu frez na elementy w formie płatków z możliwością regulacji ich wielkości przy czym całość procesu odbywa się w atmosferze powietrza a krótkotrwałe ogrzanie materiału w celu sklejenia wstęg nie wymaga chłodzenia wodnego przed ich cięciem do formy płatków. Korzystnie jest, stosowanie odpadów ze skrajnych fragmentów membran wytworzonych z włóknin termoplastycznych. Korzystnie jest, wytwarzanie wstęgi w urządzeniu umożliwiającym tylko chwilowe (części sekund) jej ogrzanie gorącym powietrzem w temperaturze o 30°C do 40°C wyższej od temperatury topnienia głównego polimerowego składnika z następczym pogrubieniem takiego odpadu poprzez zgniecenie kilku wstęg w celu ich sklejenia do grubszej taśmy. Korzystne jest, pocięcie nożem krążkowym typu frez otrzymanej taśmy odpadu na elementy w formie płatków o pożądanej wielkości determinowanej warunkami dalszego przerobu.The method of producing recyclate in the form of composite flakes in a typical device in which a ribbon is formed from cut-off extreme fragments of the membrane, where several ribbons can be processed simultaneously, is characterized by the fact that the ribbon is temporarily heated in a chamber with a temperature of 30 ° C to 40 ° C higher than the temperature the melting of the main polymer component, and then special (engraved) rolls crush a few of the obtained waste ribbons into a tape, the thickness of which can be adjusted by setting the size of the inlet channel, after which the tape is cut with a circular cutter-type cutter into flake-shaped elements with the possibility of adjusting their size the whole process takes place in the air atmosphere and the short-term heating of the material in order to glue the webs does not require water cooling before cutting them into flakes. Preferably, waste is used from end sections of the membranes made of thermoplastic nonwovens. Preferably, the production of the web is made in a device that allows it to be heated only temporarily (parts of seconds) with hot air at a temperature of 30 ° C to 40 ° C higher than the melting point of the main polymer component, followed by thickening of such waste by crushing several webs in order to glue them to a thicker layer. tapes. It is advantageous to cut the obtained waste tape with a disc cutter into flake-shaped elements of the desired size determined by the conditions for further processing.
