Abstract:
La présente invention concerne un procédé de traitement fongicide et/ou insecticide d'au moins un élément contenu dans au moins une enceinte (1) dans lequel on isole hermétiquement ladite enceinte (1) et on la soumet à un traitement thermique, au moyen d'un flux d'air, chauffé par des moyens de chauffage de manière telle que le cœur dudit élément est porté à une température comprise entre au moins 50°C et 55°C pendant au moins 1h à 16h, caractérisé en ce qu'on fait circuler le flux d'air le long d'un circuit fermé comportant un tronçon d'insufflation s 'étendant entre lesdits moyens de chauffage et ladite enceinte (1) et un tronçon d'extraction s'étendant entre ladite enceinte (1) et lesdits moyens de chauffage. L'invention concerne également un dispositif pour la mise en œuvre d'un tel procédé.
Abstract:
The present disclosure describes a treated cellulosic material comprising: a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising: a polymer comprising an olefin-carboxylic acid copolymer; and a modifying agent comprising a quat.
Abstract:
We disclose novel metallic nanoparticles coated with a thin protective carbon shell, and three-dimensional nano-metallic sponges; methods of preparation of the nanoparticles; and uses for these novel materials, including wood preservation, strengthening of polymer and fiber/polymer building materials, and catalysis.
Abstract:
Disclosed is a biocide concentrate composition to be incorporated into oil-based formulations useful for the treatment and preservation of wood. Also disclosed are oil-based biocide compositions and creosote based biocide compositions.
Abstract:
Die Erfindung betrifft biozide Mischungen enthaltend penflufenhaltige Polymerpartikel, Kupferverbindungen und spezielle Alkanolamine und deren Verwendung zum Schutz von Holz- und Holzprodukten, sowie Holzschutzmittel enthaltend biozide Mischungen und gegebenenfalls weitere Wirkstoffe.
Abstract:
According to the present invention there is provided a method of treating timber with a creosote-containing preservative formulation adapted for use at substantially ambient temperature. The formulation comprises: creosote; one or more surfactants such that when diluted with a predetermined quantity of water, the creosote is present as an oil-in-water macroemulsion or microemulsion; and optionally, an anti-foaming agent and/or a fire retardant. It is found empirically that the inventive concentrate allows for the use of creosote, a known-effective biocide, without many of the drawbacks inherent in such use.
Abstract:
Die Erfindung betrifft Penflufen enthaltende Mischungen, die Verwendung dieser Mischungen zum Schutz technischer Materialien und ein Verfahren zur Behandlung technischer Materialien mit den Penflufen Mischungen.
Abstract:
There is described a method of eliminating mould genera from cork and/or timber. The embodiments chosen involve the treatment of cork that is intended for use as a closure for a wine product while there is suggestion that the timber chosen, oak chips, would be suitable for use in the making of wine. Two examples of a cork treatment method are described. The first method treats cork surrounded by liquid under great pressure. Timber could be substituted for the cork in either method. The second method incorporates the use of a secondary container for the cork and or timber, which is also surrounded by liquid under great pressure. The liquid, in contact with the cork or timber, can contain an anti-oxidising and/or antibacterial liquid. The method can be used on raw or processed forms of cork and/or timber.
Abstract:
The present invention is directed to amine soluble, or solid copper triazole based wood preservative formulations containing certain types of quaternary ammonium compounds, or nonionic surfactants, and the use of these quaternary ammonium compound-, or nonionic surfactant-containing formulations to pressure treat and preserve wood. The addition of the quaternary ammonium compounds, or nonionic surfactants to the wood preservation treatment solutions allows improved penetration of the copper from the solution into wood and reduces the duration of time required to effectively pressure treat the wood with the preservation composition.
Abstract:
Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper ammine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.
