TEALON TF 1590 ist eine Dichtungsplatte aus strukturiertem PTFE. Aufgrund eines besonderen Herstellungsprozesses kommt es zu einer sehr starken multidirektionalen Orientierung der PTFE Moleküle. Dadurch wird das für PTFE Dichtungsplatten typische Kriechverhalten deutlich vermindert. TEALON TF1590 besteht aus virginalem PTFE und Silikat als Füllstoff.
Vorteile:
• Aufgrund der hohen mechanischen Beständigkeit ist TEALON TF 1590 bei hohen Drücken und Temperaturen einsetzbar, insbesondere in der chemischen und petrochemischen Industrie, in Verbindung mit starken Säuren, Lösungsmitteln, Wasser, Dampf, Chlor, usw.
• TEALON TF 1590 ist schnell und einfach zu installieren. Die gebrauchte Dichtung kann rückstandsfrei entfernt werden.
Hot Compression Test
Dieser Leistungstest zeigt das Verhalten von strukturiertem PTFE- und konventionellen PTFE-Dichtungen in der Anwendung. Die folgende Darstellung zeigt einen Vergleich zwischen konventionell geschältem PTFE und TEALON. Die von uns getesteten Dichtungen simulierten eine reale Anwendung, einschließlich Thermocycling. Die geschälte PTFE-Dichtung zeigte eine sehr hohe Leckrate und verlor bis zum Ende des Tests 60 % ihres Anfangsdrucks.
Die TEALON®-Dichtung verlor am Ende des Tests nur 6% ihres Anfangsdrucks und zeigte eine zehnmal höhere Dichtheit als die geschälte PTFE-Dichtung. Die Abbildungen unten zeigen die Dichtungen nach dem Test und die Dimensionsstabilität von TEALON im Vergleich zum signifikantem Kriechen der geschälten PTFE-Dichtung.
Filter leakage, due to surface irregularities between a lid and a fixed flange, caused contamination in a plant. This increased the risk for chemical burn injuries and corrosion of nearby equipment. The fragility of PVC flanges limited the ability to solve the problem by simply increasing the bo ...
