Description
Procédé de fabrication d'objets moulés en fibres végétale. Le présent brevet a pour objet un pro cédé de fabricaton d'objets moulés, en fibres végétales, résistant à l'action de l'humidité et complètement imperméables.
Ce procédé permet notamment l'utilisa tion de bois de qualité inférieure ainsi que <B>(le</B> tous déchets de bois pour la fabrication de panneaux, de planches et de tous objets de formes diverses.
Le présent procédé est caractérisé par ce fait que les fibres végétales sont agglutinées au moyen d'une colle de caséine et sont son- mises, pendant leur moulage, à la fois à une forte compression et à l'action de la chaleur.
A titre d'exemple, il va être décrit ci- dessous un mode de réalisation du présent procédé.
Les fibres végétales, obtenues par exem ple par défibrage de branches, de billots etc. sont immergées dans un bain composé de colle de caséine diluée dans l'eau, par exem ple dans la proportion de 1 lu, de colle de caséine pour 15 litres d'eau.
Cette colle de caséine est constituée par une dissolution de caséine dans de l'ammo- nuque comprenant environ 88 % de caséine et 12 % d'ammoniaque. Après immersion dans ce bain, les fibres sont égouttées et pla cées à l'état humide dans des moules de forme appropriée aux objets à fabriquer.
fendant leur moulage, les fibres ainsi enduites d'agglutinant sont fortement coin- primées et en même temps chauffées à une température d'environ 130 C. Sous l'action (le la chaleur, l'ammoniaque et l'eau, dont les fibres sont imprégnées, s'évaporent, et il ne reste plus finalement comme agglutinant que la caséine pure.
En raison de sa nature spéciale, cette der nière assure une liaison parfaite des fibres et a, en outre, l'avantage de résister à l'action (le l'humidité, de telle sorte due les produits moulés ainsi obtenus conservent toujours une cohésion parfaite et restent indéformables même lorsqu'ils sont mouillés.
Dans le but de rendre imputrescibles les produits fabriqués, on peut ajouier dans le bain agglutinant nue matière antisepticille telle qiac. par exemple, l'acide foriniqite. Il est bien entendu que la composition le colle de caséine indiquée ci-dessus n'esl donnée qu'à titre d'indication, e1 qu'on leus employer également toute dissolution de ca séine contenant, par exemple, soit du car bonate de magnésie, soit le la chaux éteinte, sois du borate de soude.
Ainsi qu'il a été dit ci-dessus, le présent procédé permet de fabriquer des objets le formes diverses; par ce procédé, on peut ob tenir notamment soit des panneaux, le foutes dimensions et de toutes formes, avec ou non des parties en relief offrant l'aspect (le sculp tures, soit les planches susceptibles d'être utilisées dans l'ébénisterie, ci d'être iravail- lées comme les bois ordinaires.
Dans le but (le donner aux panneaux, planches ou objets divers fabriqués par le présent procédé, L'as pect des différentes essences de bois, on pourra saupoudrer la face externe du produit moulé, au cours de sa cuisson dans son moule, de sciure de l'essence de bois voulue, lar exemple de poudre le noyer, d'acajou, de palissandre etc.: les fibres pourront également tfre colorées avant leur encollage.
Process for manufacturing objects molded from vegetable fibers. The present patent relates to a process for manufacturing molded objects made of plant fibers, resistant to the action of humidity and completely impermeable.
This process allows in particular the use of inferior quality wood as well as <B> (the </B> all wood waste for the manufacture of panels, planks and all objects of various shapes.
The present process is characterized by this fact that the vegetable fibers are agglutinated by means of a casein glue and are subjected, during their molding, to both strong compression and the action of heat.
By way of example, an embodiment of the present method will be described below.
Vegetable fibers, obtained for example by defibrating branches, logs, etc. are immersed in a bath composed of casein glue diluted in water, for example in the proportion of 1 µl, of casein glue to 15 liters of water.
This casein glue consists of a solution of casein in ammonia comprising approximately 88% casein and 12% ammonia. After immersion in this bath, the fibers are drained and placed in the wet state in molds of suitable shape for the objects to be manufactured.
splitting their molding, the fibers thus coated with binder are strongly cornered and at the same time heated to a temperature of about 130 C. Under the action (heat, ammonia and water, the fibers of which are impregnated, evaporate, and ultimately all that remains as a binding agent is pure casein.
Due to its special nature, the latter ensures a perfect bond of the fibers and has, in addition, the advantage of resisting the action (humidity, so due to the molded products thus obtained always retain a cohesion perfect and remain undeformable even when wet.
In order to make the produced products rot-proof, one can add in the agglutinating bath bare antisepticil material such as qiac. for example, foriniqite acid. It is understood that the composition the casein glue indicated above is only given as an indication, and that they also use any solution of ca seine containing, for example, either car bonate of magnesia , either slaked lime, be sodium borate.
As has been said above, the present process makes it possible to manufacture objects of various shapes; by this process, one can obtain in particular either panels, all dimensions and of all shapes, with or not parts in relief offering the aspect (the sculp tures, or the boards likely to be used in cabinet making, ci to be worked like ordinary antlers.
For the purpose (to give it to the panels, boards or various objects manufactured by the present process, The appearance of the different wood species, we can sprinkle the external face of the molded product, during its baking in its mold, with sawdust the desired wood species, for example walnut powder, mahogany, rosewood etc .: the fibers can also be colored before gluing.
