Abstract

Przedmiotem zgłoszenia jest sposób wielokrotnego przetwarzania wyrobów z biodegradowalnego kompozytu termoplastycznego. Sposób według wynalazku charakteryzuje się tym, że wyrób z biodegradowalnego kompozytu zawierającego od 55 do 85 cz. wag. poli(kwasu 3-hydroksymasłowego-co-3-hydroksywalerianowego) oraz od 15 do 45 cz. wag. napełniacza w postaci włókien konopnych mieli się, po czym uzyskany regranulat suszy się, a następnie uplastycznia się w temperaturze od 175°C do 190°C oraz wytwarza się nowy wyrób.The subject of the application is a method for repeated processing of products made of a biodegradable thermoplastic composite. The method according to the invention is characterized by the fact that the product is made of a biodegradable composite containing from 55 to 85 parts. weight poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) and from 15 to 45 parts. weight filler in the form of hemp fibers is ground, then the obtained regranulate is dried and then plasticized at a temperature of 175°C to 190°C and a new product is produced.
