Können PE-Rohre der Sonne ausgesetzt werden?

2025-08-19

Im täglichen Leben und in allen Arten des Ingenieurbaus werden PE-Rohre wegen ihrer hervorragenden Leistung häufig verwendet. Viele Benutzer werden jedoch über eine praktische Frage besorgt sein: Können PE-Rohre der Sonne ausgesetzt werden?

Wir wissen, dass PE-Rohre hauptsächlich aus Polyethylen hergestellt werden. Polyethylen selbst hat eine gewisse chemische Stabilität, aber eine langfristige Exposition gegenüber direktem Sonnenlicht, insbesondere ultravioletten Strahlen, hat einen gewissen Einfluss auf die Leistung von PE-Rohren. Ultraviolette Strahlen sind einer der wichtigsten Faktoren, die zur Alterung von Kunststoffen führen. Es wird allmählich die molekulare Struktur von PE-Rohren verändern. Es kann zu Oberflächenrissen, hellerer Farbe und verminderter mechanischer Festigkeit kommen, was die Lebensdauer und Sicherheit des Rohrs beeinträchtigt.

Bedeutet dies also, dass PE-Rohre überhaupt nicht in der Sonne verwendet werden können? Tatsächlich ist es das nicht. Bei der Herstellung von PE-Rohren hat AD Pipe die Bedürfnisse der verschiedenen Einsatzumgebungen vollständig berücksichtigt. Um die UV-Beständigkeit von PE-Rohren zu verbessern, fügt AD Pipe den Rohstoffen eine angemessene Menge an Zusatzstoffen wie UV-Stabilisatoren hinzu. Diese Zusatzstoffe können ultraviolette Strahlen wirksam absorbieren oder abschirmen und die Schädigung der Molekularstruktur von PE-Rohren durch ultraviolette Strahlen verlangsamen, wodurch die Witterungsbeständigkeit von PE-Rohren im Freien verbessert wird.

Dennoch empfehlen wir, bei der Installation und Verwendung von PE-Rohren zu versuchen, eine langfristige und kontinuierliche Exposition von PE-Rohren gegenüber starker Sonneneinstrahlung zu vermeiden. Wenn die Rohre im Freien verlegt werden müssen, sollten geeignete Schutzmaßnahmen getroffen werden. Beispielsweise können die PE-Rohre mit Erde abgedeckt und vergraben werden, oder es kann ein physischer Schutz durch Sonnenschirme, Sonnenschutzbeschichtungen usw. durchgeführt werden, um die direkte Exposition gegenüber ultravioletten Strahlen zu reduzieren. Dadurch wird nicht nur die Lebensdauer des PE-Rohrs effektiv verlängert, sondern auch sichergestellt, dass seine verschiedenen Leistungsindikatoren bei langfristiger Nutzung stabil bleiben.

Kurz gesagt, das PE-Rohr ist nicht völlig unfähig, der Sonne standzuhalten, aber langfristige ungeschützte Sonneneinstrahlung hat tatsächlich negative Auswirkungen auf seine Leistung und Lebensdauer. Wählen Sie eine Marke wie AD Pipe, die auf Produktqualität und -leistung achtet, und das von ihr hergestellte PE-Rohr ist in Bezug auf UV-Beständigkeit und andere Wetterbeständigkeit sicherer. Gleichzeitig kann das PE-Rohr in Verbindung mit angemessenen Installations- und Schutzmaßnahmen eine gute Rolle in verschiedenen Umgebungen spielen und bietet eine zuverlässige Unterstützung für unsere Produktion und unser Leben.
