Abstract

"PRODUTO TUBULAR ALONGADO". Esse produto tubular alongado, apresenta a mesma seção de acordo com toda sua direção longitudinal, compreende um tubo sólido (1), constituído por pelo menos um material plástico, ao mesmo tempo suficientemente flexível para ser ele próprio enrolado e desenrolado, e suficientemente rígido para resistir ele próprio a um esforço radial centrípeto ou centrífugo, o dito tubo sólido possuindo, no lado interior e/ou no lado exterior, uma camada superficial (3) cuja superfície livre constitui uma superfície de atrito e que possui uma matriz plástica na qualf é distribuído um lubrificante. De acordo com a invenção, de maneira sinérgica, por um lado partículas (4) de um lubrificante de natureza sólida são distribuídas na matriz plástica, aflorando pelo menos em parte ao nível da superfície livre da camada superficial, e por outro lado um lubrificante de natureza líquida, compatível com a matriz plástica, é dispersado na camada superficial, praticamente sem molhar a superfície livre dessa última."STRETCHED TUBULAR PRODUCT". This elongated tubular product, presents the same section according to all its longitudinal direction, comprises a solid tube (1), constituted by at least one plastic material, at the same time sufficiently flexible to be rolled and unrolled, and sufficiently rigid to resist itself to a centripetal or centrifugal radial effort, said solid tube having, on the inside and / or on the outside, a superficial layer (3) whose free surface constitutes a friction surface and which has a plastic matrix in which it is lubricant is distributed. According to the invention, synergistically, on the one hand, particles (4) of a lubricant of a solid nature are distributed in the plastic matrix, at least partly emerging at the level of the free surface of the surface layer, and on the other hand a lubricant of liquid nature, compatible with the plastic matrix, is dispersed in the superficial layer, practically without wetting the free surface of the latter.
