Abstract
Dichtung für Flanschen bei Temperaturen über 500°C, bestehend aus einem mindestens eine Durchlaßöffnung aufweisenden flächigen Glimmerwerkstoff, der mehrere übereinandergeschichtete flache, mit der Fläche ihrer größten Ausdehnung parallel zu den Dichtungs-Außenflächen (4A, 4B) gerichteten Glimmerscheibchen (16) aus Phlogopit-Glimmer enthält, die von vielen dünsten, von der natürlichen Materialbindung zusammengehaltenen Glimmerplättchen gebildet sind. Der Glimmerwerkstoff (1) enthält zwischen Überlappungsbereichen übereinanderliegender Glimmerscheibchen (16) eine Bindemittelschicht (18) aus Kunstharz. Für den Glimmerwerkstoff (1) ist ein Material gewählt, dessen Dicke (D) bei Temperaturen über 500° eine erhebliche und progressive Zunahme gegenüber der Dicke bei 20° erfährt. Durch die Dickenzunahme gleicht die Dichtung temperaturbedingte Verwerfungen der abzudichtenden Flanschflächen aus.
