Kan PVC-lijm aan PE-buizen blijven plakken?

2025-08-19

Tijdens de installatie en het onderhoud van pijpleidingen zullen veel mensen vragen: kan PVC-lijm aan PE-buizen blijven plakken? Het antwoord is nee, PVC-lijm is niet geschikt voor het verlijmen van PE-buizen. Dit komt voornamelijk omdat PVC (polyvinylchloride) en PE (polyethyleen) twee chemisch verschillende plastic materialen zijn en hun moleculaire structuur en fysische eigenschappen aanzienlijk verschillen.

Het belangrijkste principe van PVC-lijm is om het oppervlak van PVC-buizen op te lossen of op te zwellen om een nauwe band tussen moleculen te vormen, om een effectieve binding te bereiken. De oppervlakteactiviteit van PE-buizen is laag en de chemische eigenschappen zijn relatief stabiel. PVC-lijm is moeilijk te infiltreren op het oppervlak en kan geen vaste houdkracht vormen. Als PVC-lijm met geweld wordt gebruikt om PE-buizen te binden, kan dit niet alleen de verbindingssterkte niet garanderen, maar kan het ook leiden tot problemen zoals lekkage en vallen van de interface, wat de veiligheid en levensduur van het pijpleidingsysteem ernstig beïnvloedt.

De veilige werking van het pijpleidingsysteem is van het grootste belang en de verkeerde verbindingsmethode kan veel verborgen gevaren veroorzaken. Als professionele leverancier van pijpleidingsysteemoplossingen wil AD Pipe de meerderheid van de gebruikers eraan herinneren dat PE-buizen hun eigen speciale verbindingsmethoden hebben, zoals hot-melt docking, elektrofusieverbinding, enz. Deze methoden zorgen ervoor dat de pijpmoleculen diffunderen en met elkaar samensmelten om een geïntegreerde verbindingsstructuur te vormen door het verbindingsdeel van de PE-buis te verwarmen met de gesmolten toestand en vervolgens te dokken of in te brengen. Dit zorgt voor een hoge interfacesterkte en een goede afdichting, waardoor de stabiele werking van het pijpleidingsysteem op lange termijn effectief kan worden gegarandeerd.

Daarom moet u bij het aansluiten van PE-buizen speciale verbindingsgereedschappen en -methoden kiezen die voldoen aan de specificaties en niet proberen het gebruik van ongeschikte hechtingsmaterialen zoals PVC-lijm te vergemakkelijken. Als u meer wilt weten over de professionele kennis van PE-pijpverbinding of hoogwaardige PE-pijpfittingen wilt kopen, kunt u de relevante technici van AD Pipe raadplegen, wij zullen u professionele begeleiding en betrouwbare productondersteuning bieden om een veilig en efficiënt leidingsysteem te helpen creëren.
