摘要:
L'invention concerne une zéolite de type faujasite X à basse teneur en silice, plus précisément une zéolite LSX de rapport atomique Si/Al inférieur ou égal à 1,15, présentant un taux de cristallinité élevée et dont les cristaux présentent une distribution granulométrique contrôlée. La présente invention a également trait au procédé de préparation de ladite zéolite LSX.
摘要:
The invention relates to a faujasite X zeolite with a low silica content, more precisely an LSX zeolite with an Si/Al atomic ratio of 1.15 or less, having a high degree of crystallinity, the crystals of the zeolite having a controlled particle size distribution. The present invention also relates to a method of preparing said LSX zeolite.
摘要:
The invention relates to zeolithic compositions containing at least one type of A, X and Y zeolite and/or chabazite and at least one type of clinoptilolite zeolite. The inventive zeolithic compositions are usable in adsorbing methods for removing H 2 O and/or CO 2 and/or H 2 S contained in gas or liquid mixtures, in particular for purifying natural and acid gases, alcohols and mercaptans.

Appareil d'application d'une bandelette (S) de mélange caoutchouteux de faible épaisseur et de faible largeur, sur une surface de réception (2) en mouvement relatif par rapport audit appareil, qui comprend un corps (10) comportant au moins une vis d'extrusion principale (11) montée à rotation dans une chambre (13) destinée à refouler un mélange caoutchouteux dans un patin de reprise (20) qui coopère avec la surface de réception (2) de sorte à former avec cette dernière un orifice d'extrusion (16) définissant le profil de la bandelette (S), caractérisé en ce que la pression d'application du mélange à l'entrée de l'orifice d'extrusion (16) est générée par la vitesse d'entraînement du mélange caoutchouteux par la surface de réception (2) en mouvement, associée à un effet de l'angle que forme la voûte (205) du patin de reprise et la surface de réception (2).
摘要:
The invention concerns a superabsorbent composition containing a superabsorbent polymer powder, for instance polyacrylic and a zeolite powder exchanged with metal cations with bactericidal properties, in particular with silver ions. The hygiene articles incorporating them do not give off nor develop unpleasant smells though soaked with corporeal liquids.
摘要:
The present invention relates to an agglomerated zeolite adsorbent containing at least one polymer matrix that is greatly laden with at least one zeolite adsorbent. The invention also relates to the method for preparing such an adsorbent and to the uses thereof, particularly as an adsorbent of moisture, odors, volatile organic components, and the like.
摘要:
The invention relates to a motor vehicle wheel set-up via a wheel holder, said wheel holder being associated with said vehicle via at least one pivot in such a way that the plane of the wheel can exhibit first and second angular running positions, said set-up further comprising a binary actuator that has a fixed component (1) and a moving component (2) capable of translational movement with respect to said fixed component, said moving component being secured to the wheel holder and said actuator comprising a device for the binary control of the moving member (2) placing it in one of two stable states each allowing the wheel holder to be moved into an angular position corresponding to one angular position of the wheel plane.
摘要:
La présente invention concerne des compositions zéolitiques au moins une zéolite A, X, Y et/ou chabazite et au moins une zéolite de type clinoptilolite. Ces compositions zéolitiques sont utilisables dans des procédés d'adsorption pour l'élimination de H 2 O et/ou CO 2 et /ou H 2 S contenus dans des mélanges gazeux ou liquides, notamment pour l'épuration du gaz naturel, des gaz acides, des alcools et des mercaptans.
摘要:
.The invention concerns an extruding device (1) for making a rubber mixture based product, comprising a rotary roller (5), an inlet (15) for said rubber mixture and a roof (6) circumferentially covering partly the surface (51) of the roller (5), the rubber mixture being delivered from the inlet orifice (15) into the air gap located between the roof (6) and the roller (5) towards an extruding orifice (21) defining the profile of the product, delimited by a wall (20) which co-operates with the outer surface (51) of the roller (5), the roof (6) bears on its inner surface oriented towards the roller projecting threads so as to delimit with the surface of the roller (51) a chamber for plasticizing the mixture, two at least of the threads extending substantially axially.
摘要:
The present invention relates to a masterbatch in agglomerated solid form comprising: a) carbon nanofibres and/or nanotubes and/or carbon black, the content of which is between 15 wt% and 40 wt%, preferably between 20 wt% and 35 wt%, relative to the total weight of the masterbatch; b) at least one solvent; c) at least one polymer binder, which represents from 1 wt% to 40 wt%, preferably from 2 wt% to 30 wt% relative to the total weight of the masterbatch. The present invention also relates to a concentrated masterbatch, characterized in that it is obtained by eliminating all or part of the solvent from the masterbatch described previously. It also relates to a process for preparing said masterbatches and to the uses of the latter, especially in the manufacture of an electrode or of a composite material for an electrode.
