Definitions

  • the present description refers to an application for Privilege of Invention for a new and revolutionary "COMPOSITION AND PROCESS TO OBTAIN MASS FOR PROFILE EXTRUSION AND COVERING", which purpose is to obtain, by means of a new compound, a specific mass which, when applied to a production process, provides for the covering of profiles made of wood or a similar material, so to perfectly fill in pores or imperfections, also increasing resistance and improving results at the end of the covering process, being a specifically developed product which is applied by means of an also specific process to immediately obtain general profiles and frames of wood or similar material with precise and perfect finishing, and this whole set has been developed, despite the numerous tests and studies, in a practical and very simplified way, being thus able to meet the current requirements and demands.
  • Water-based gypsum is currently known from the state of the art and has been used in the covering process for wood frames for pictures.
  • extruder This product is applied by means of a special application machine called extruder.
  • frames are continually moved through a chamber full of gypsum which passes through a hole with similar shape to the frame profile, so to receive covering from that gypsum.
  • the object of this operation is to apply enough product to fill in wood pores and prepare the frame for the following covering steps.
  • Another object of the present invention is to improve the resistance to substances and, in general, technical properties of the covering film, so to improve the final result of the covering process.
  • Tonifying paste 0 - 5 % As for the vinyl resin, in principle all kinds of saturated vinyl resins are appropriate. Modified vinyl resins may also be used, such as: types modified with polyvinyl alcohol, with styrene or VeoVa and all their combinations.
  • An appropriate tonifying paste for use may be any commercial type, as long as fully water-dispersible and compatible. Those types with low quantity of added glycols should be used.
  • Mixing procedures should be conducted under relatively low shaking speed (maximum 500 rpm), taking care for the temperature not to exceed 50 0 C during the mixing process.
  • Mixing should be conducted for no longer than 45 minutes. In principle, any kind of commercial mixer allowing to obtain and maintain the above values may be used.
  • the real critical point to obtain a good result is the mixing procedure, which should be conducted so to homogenize and not disperse the product.
  • the mixing machine may be shaped so to enable mixing to occur under low rpm, with no remarkable temperature increase.
  • a possible formulation may be prepared by using acrylic resin or a mixture of acrylic and vinyl resin.
  • This whole compound as now prepared should be used in an extruding machine, so to distribute it throughout the profile surface, aiming to cover each and any porosities or imperfections of the wood or similar material.
  • This extruding machine as recommended is a machine to make extrusion over compression, so to enable the used mass to penetrate all possible pores and imperfections in the profiles, so to not only cover but also fully fill them in, so that they can no longer be seen and identified, thus providing perfect finishing to the work.
  • spatula When we manually soothe a wood part so to cover its failures, we usually employ a spatula not only to spread out the mass, but also to promote some compression for it to penetrate and fill in failures.
  • the extruding machine will make so by compression, i. e. the profile will pass through a chamber containing the mass, a compound as claimed herewith, under pressure, which will exit through compatible holes, which will define which shape the profile will be, i. e. even and with no failures.

Abstract

L'invention porte sur une composition et un procédé pour obtenir une masse pour l'extrusion et le revêtement de profilés, mis au point pour obtenir un mélange qui, ajouté à une extrusion par compression, assure d'une manière pratique et rapide l'obtention d'un revêtement parfait de profilé de bois ou matériau analogue, en dehors du fait de réduire le temps de travail manuel et le coût. Ce mélange est caractérisé par le fait qu'il est constitué par une résine vinylique en dispersion dans l'eau (entre 20 et 30%), du carbonate de calcium (entre 65 et 75%) et une pâte tonifiante (entre 0 et 5%). Un tel mélange desdites matières ou de matières de remplacement devrait être effectué sous une faible vitesse d'agitation (maximum 500 tpm) de telle sorte que la température peut ne pas dépasser 50°C et l'homogénéisation de produit prend au maximum 45 minutes, ledit mélange tel que préparé étant utilisé avec une machine d'extrusion par compression, provoquant ainsi la pénétration de la masse obtenue à travers tous les pores et imperfections des profilés de bois ou matériau analogue, visant à recouvrir lesdites imperfections par un nombre réduit de passes et à le distribuer à travers toute la surface, lui conférant une perfection et un fini parfait plus résistant.
