Abstract:
The invention relates to a process for coating the surface of a moving wire (50) with a thin solid polymer layer. The process includes the step of providing a deposition device (100) having a compartment (108d') of a chamber (108) that contains two rotatable rings (110) and two wheels including an upper wheel (114) and a lower wheel (114') having circumferential grooves (114b, 114b') in which the two rings (110) are lodged. The wheels (114, 114') are placed vertically on either side of the wire (50) by means of the grooves (114c, 114c') such that a predetermined contact force between the wheels (114, 114') and the wire (50) makes it possible, by friction, when the wire (50) moves at constant speed, to rotate the wheels (114, 114') and the rings (110) too. The device also includes a tank (106) containing a liquid polymer solution (75). The wire (50) is conveyed at a predetermined constant speed, and the rotatable rings (110) are rotated, these conveying an amount of the liquid polymer solution (75). The process also includes the step of evaporating the solvent from the liquid polymer solution (75) deposited at the surface of the wire (50).
Abstract:
L'invention concerne un procédé de fonctionnalisation de nanofils métalliques et l'utilisation de ces derniers. Le procédé de fonctionnalisation de l'invention comprend une étape de formation d'une couche monomoléculaire auto-assemblée, sur au moins, une partie de la surface externe de nanofils métalliques, à partir d'un composé de formule R 1 -Z n -R 2 dans laquelle Z est S ou Se, et n est égale à 1 ou 2, et R 1 est un atome d'hydrogène ou un groupe acyle ou un groupe hydrocarboné comprenant de 1 à 100 atomes de carbone et R est un groupement électroattracteur ou électrodonneur. Le procédé de l'invention trouve application dans le domaine de la fabrication d'électrode, en particulier.
Abstract:
An elongated steel element (12) with a martensite, tempered martensite, bainite or sorbite structure has a polymer coating (16) with a thickness lower than 20 μm immediately upon the elongated steel element (14). The friction coefficient and corrosion resistance are both improved by the polymer coating at a lower cost.
Abstract:
The present invention provides a distinctive method and apparatus (20) for forming an article which includes one or more selectively configured strands of material. In particular aspects, the invention can provide a method and apparatus for wrapping a strand of material with selected filaments, and desirably, the filaments can be adhesive filaments. The technique of the invention can include a moving of a strand of material (22) at a selected speed along an appointed machine-direction (34). At least a first, substantially continuous filament (24) can be directed onto the strand of material (22) along a corresponding, oscillating filament path (26) to form a first plurality of filament threads (28) which extend from opposed lateral side regions (30) of the strand of material (22). In particular aspects, at least a second, substantially continuous filament (24a) can be directed onto the strand of material (22) along a corresponding, oscillating filament path (26a) to form a second plurality of filament threads (28a) which extend from opposed lateral side regions (30) of the strand of material (22). Additionally, at least one air stream (32), and desirably a plurality of air streams are directed to operatively wrap the filament threads (28, 28a) around their corresponding strand of material (22).
Abstract:
The present invention relates to a wire coating composition comprising an infrared radiation sensitive compound resulting in the conversion of absorbed light energy into heat and a matrix with a varnish that responses either chemically or physically upon treatment with heat, to a method of producing an enameled wire and to the use thereof.
Abstract:
Eine Vorrichtung zur Beschichtung zumindest einer Faser, mit beispielsweise zumindest zwei Plasmaspritzeinrichtungen zum Einbringen von mit einem Plasma aktivierten Pulverteilchen in einen Beschichtungsbereich. Des Weiteren kann die Vorrichtung eine Pulverfördereinrichtung zum Bereitstellen von Pulverteilchen zu den zumindest zwei Plasmaspritzeinrichtungen und eine Fasertransporteinrichtung aufweisen, die ausgebildet sein kann, die zumindest eine zu beschichtende Faser durch den Beschichtungsbereich zu führen, um eine Beschichtung der zumindest einen Faser mit den aktivierten Pulverteilchen in dem Beschichtungsbereich zu bewirken. Die zumindest zwei Plasmaspritzeinrichtungen können in einem Winkel und/oder in einer Längsrichtung, der zumindest einen Faser, zueinander versetzt angeordnet sein und auf den Beschichtungsbereich gerichtet sein.
