Abstract:
A treatment method for treating the surface of a fluid dispenser device, said method comprising the step of using chemical grafting to form a thin film on at least one support surface of at least one component part that is in contact with said fluid, said thin film preventing interactions between said fluid and said component part.
Abstract:
This gauge for mounting a screw in a cage nut or in a nut (23), with the aim of assembling at least two parts (13, 15), comprises a shank (37) with a smooth section (39) having graduations (47) and with a threaded end (41), which are similar to those of said screw. A sleeve (49) is slidably mounted on said smooth section (39). The axial length of said sleeve (49) and the distribution of said graduations (47) are such that, when the shank (37) of said gauge is screwed as far as it will go into said cage nut or into said nut (23) and when said sleeve (49) is pressed against one (13) of said two parts (13, 15), the graduation indicated by said sleeve (49) on said smooth section (39) is representative of the distance separating the thread (43) of said cage nut or said nut (23) from the outer surface of the part (13) situated facing away from this cage nut or said nut (23).
Abstract:
A treatment method for treating the surface of a fluid dispenser device, said method comprising the step of using chemical grafting to form a thin film on at least one support surface of at least one movable portion of said device that is movable while said device is being actuated, said thin film having anti-friction properties.
Abstract:
A treatment method for treating an elastomer surface of a fluid dispenser device, the method including the step of using chemical grafting to form a thin film on at least one support surface of at least one elastomer surface of the dispenser device, the thin film avoiding the elastomer surfaces sticking during the manufacturing and assembly stages.
Abstract:
The present invention concerns a method for the lubrication of the surface of a solid by grafting a polymer gel, and for impregnation with a lubricating composition, and a kit to prepare a solid comprising a surface lubricated with a polymer gel.
Abstract:
A treatment method for treating the surface of a fluid dispenser device, said method being characterized in that it comprises a step of using chemical grafting to form a thin film on at least one support surface of at least one portion of said device that is in contact with the fluid while said device is being actuated, said thin film having non-stick properties relative to said fluid.
Abstract:
The present invention relates to a coating method by electrocatalyzed chemical grafting of a surface of a substrate with a polymeric layer characterized in that it comprises the following steps: a. a substrate is provided, b. a bath containing at least one polymerizable monomer via a radical route, at least one cleavable aryl salt, at least one reducing agent and at least one solvent is provided, in which a potential difference is applied, c. said substrate is immersed in said bath, d. a grafted polymer is obtained on the surface of said substrate. The invention also relates to a substrate obtained according to the coating method by electrocatalyzed chemical grafting, the surface of which is coated with a polymeric layer.
