Abstract
Przedmiotem wynalazku jest sposób wytwarzania, metodą wtrysku, odpornych na działanie substancji chemicznych elementów z polisulfonu fenylenu. W sposobie tym, materiał wyjściowy podany z leja zasypowego wtryskarki do ogrzewanego cylindra, uplastycznia się i następnie jest wtryskiwany przez dyszę i tuleję wtryskową do gniazd formujących formy wtryskowej, a po zestaleniu jest usuwany z formy w postaci gotowej wypraski charakteryzuje się tym, że przed wtryskiwaniem przez dyszę i tuleję wtryskową materiału wyjściowego do formy wtryskowej, na powierzchnię gniazda formującego formy wtryskowej, aplikuje się rozpylaczem drobnokropelkowy aerozol polimeru o działaniu barierowym, przy czym adhezja substancji polimeru o działaniu barierowym do powierzchni polisulfonu fenylenu w temperaturze 180 - 200°C wtrysku jest silniejsza niż do powierzchni gniazda formującego formy wtryskowej Po zamknięciu formy wtryskowej dokonuje się pod ciśnieniem min 800 bar, wtrysk uplastycznionego polisulfonu fenylenu o temperaturze 360 - 420°C, a następnie po stabilizacji tworzywa chłodzi się wyrób do temperatury 180 - 200°C i po ochłodzeniu do temperatury niższej od temperatury zestalenia, formę wtryskową otwiera się, a wypraskę (wyrób) uwalnia z gniazd formujących.The subject of the invention is a method of manufacturing, by injection method, chemical-resistant elements of polyphenylene sulfone. In this method, the starting material fed from the hopper of the injection molding machine to the heated cylinder is plasticized and then injected through the nozzle and injection sleeve into the mold cavities of the injection mold, and after solidification it is removed from the mold in the form of a finished part, characterized in that it is characterized before through the nozzle and the injection sleeve of the starting material to the injection mold, on the surface of the mold cavity of the injection mold, a fine-drop polymer aerosol with a barrier effect is applied with the spray, while the adhesion of the polymer substance with a barrier effect to the surface of polyphenylene sulfone at the injection temperature of 180 - 200 ° C is stronger than to the surface of the mold cavity of the injection mold After the injection mold is closed, the injection molding is carried out at a pressure of min. 800 bar, injection of plasticized polyphenylene polysulfone at a temperature of 360 - 420 ° C, and then, after stabilization of the material, the product is cooled to a temperature of 180 - 200 ° C and after cooling to temperature ni lower than the setting temperature, the injection mold is opened and the compact (product) is released from the molding cavities.
