Abstract

La présente invention concerne l’utilisation d’une composition en polyamide pour fabriquer une pompe ou une soupape et en particulier le procédé pour fabriquer une pompe ou une soupape en utilisant un composite de polycaprolactame. L’invention concerne également la pompe ou la soupape moulée à partir du composite. Cette pompe ou cette soupape est préparée en mélangeant minutieusement 60 à 80 % en poids d’un monomère de caprolactame, 2 à 30 % en poids de charges, 1,4 à 3 % en poids de métal sodium ou d’hydroxyde de sodium, 3 à 6 % en poids d’un cocatalyseur et analogue dans un récipient de réaction sous agitation, en faisant couler le mélange résultant dans un moule et en polymérisant le mélange. La pompe ou soupape résultante présente d’excellentes propriétés mécaniques telles qu’une résistance à la traction ≥ 97 Mpa, une résistance à l’abrasion qui représente deux à trois fois celle de l’acier, une résistance élevée à l’impact, une résistance élevée à l’acide ou aux alcalis, une bonne propriété d’autolubrification, un facteur élevé de résilience, un faible rapport d’absorption de l’eau qui est 2 à 2,5 fois moins important que celui des plastiques industriels classiques et une stabilité dimensionnelle.
