Abstract

Der Tintenausstoßkanäle (3) aufweisende Kopfteil (1) des Tintenschreibkopfes ist mit einer kautschukelastischen Vergußmasse (7) in eine äußere Halterung (6) eingegossen. Auf der Seite der Austrittsöffnungen (4) der Tintenausstoßkanäle (3) befindet sich eine Silanisierungsschicht (5), deren hydro­ phobierende Wirkung durch vor dem Vergießen der Vergußmasse (7) zugesetztes Silikonöl verstärkt wird, da das später aus der Vergußmasse (7) langsam ausdiffundierende Silikonöl sich durch Kriechen ausbreitet und auf der Silanisierungsschicht (5) eine Silikonölschicht bildet. Die Silikonölschicht (8), die ständig aus dem Innern der Vergußmasse (7) ergänzt wird, schützt auch gleichzeitig die Silanisierungsschicht (5) vor Hydrolyse. Die vorgeschlagenen Maßnahmen sind für sämtliche Tintenschreibköpfe die mit wäßriger Tinte arbeiten geeignet. The head (1) of the ink ejection channels (3) Ink head is made with a rubber elastic Potting compound (7) poured into an outer holder (6). On the side of the outlet openings (4) of the ink ejection channels (3) there is a silanization layer (5), the hydro phobic effect by before the casting compound is poured (7) added silicone oil is reinforced, as this later from the Potting compound (7) slowly diffusing silicone oil through Creep spreads and on the silanization layer (5) Silicone oil layer forms. The silicone oil layer (8), the is constantly added from inside the casting compound (7), also protects the silanization layer (5) at the same time Hydrolysis. The proposed measures are for everyone Ink heads that work with aqueous ink are suitable.
