Description
Procédé<B>de</B> fabrication dobjets monlés avec<B>de</B> la caséine formolée. Les -caséines formoMes telles que la gala.- lithe sont -difficilement moulables du fait de leur élasticité qui entre en jeu pour déformer les objets<B>à</B> leur sortie -du moule.<B>Il</B> en ré sulte que jusqu'alors la galalithe ne peut être obtenu,-, que sous forme ;de plaques, blocs ou bâtons, desquels on<B>"</B> tire par un travail mé#ea,- nique approprié, taillage ou découpage, les articles ouobjets désirés.
Les déchets ainsi obtenus sont importants et jusqu'alors inutilisables, puisqu'on consi- ,dère #que toute caséine forrnolée ne peut être régénérée.
La présente invention est relative<B>à</B> un procédé de fabrication d'objets moulés avec de la caséine formolée, qui se -caractérise en ce ique -de la -caséine formolée, rendue légère ment acide par contact avec de l'ap-ide phé- nique, est, après mise en poudre, mélangée <B>à</B> une aldéhyde, par exemple, l'ald6hyde for- inique, le mélange étant ensuite soumis dans des moules,<B>à</B> uni-, haute pression et simul- tanknent <B>à,
</B> une température d'au moins <B>100 Il</B> C. Pour la réalisation -du procédé, il est<B>né-</B> cessaire que les facteurs température et pres sion entrent en jeu simultanément et les va riations que l'on fait subir<B>à</B> l'un ou l'autre donnentdes -produits dont les caractéristiques sont lécèrement -différentes. C'est le jeu com- binéde ces variations température et pression qui permet -dobtenir une grande variété de -produits, pouvant être utilisés -dans les appli cations les plus dif férentes.
En traitant les matières<B>à</B> l'état rigou reusement sec on arrive<B>à</B> la, suppression to tale du retrait.
Le procédé objet !de l'invention, permet, au momentdu moulage et du fait --de la tem pérature -utilisée, de produire un: phénomène analogue à,celui connu soius le nom de baké- lisation.
La matière compacte obtenue est d'une dureté remarquable; elle est complètement ininflammable et est susceptible<B>de</B> résister RUX hautes tem-péra.tur,-s, même sous de faibles épaisseurs; ell,-- peut être considérée comme incassable;<U>tomme</U> diélectrique, elle peut s'appliquer même sous de faibles épais- seurs aux isolements<B>à</B> haute tension. E Ile résiste a ux corps gras et même<B>à</B> l'action de l'huile bouillante et ne subit aucun ramollis sement sous l'action -de la ehaleur contraire ment aux autres agglomérés -connus utilisant des gommes laques ou résines.
On peut obtenir ainsi tout objet moulé, de même qu'il est possible de constituer des plaques ou bâtons de toutes formes ou dia mètres analogues<B>à</B> ceux que l'on vend sous la dénomination de galalithe. On peut aussi mélancer <B>à</B> ces matières des charges de toute nature et faire toutes les -combinaisons de eo- loration qui pourraient convenir.
On obtient même résultat lorsqu'on son- met la matière en poudre<B>à</B> l'action d'une al- déhycle autre que l'aldéhyde formique et notamment l'acétaldéhyde, la berzaldéhyde, la crotonaldéhyde, etc.
Process <B> of </B> manufacture of objects monlated with <B> of </B> formalin casein. Formal caseins such as gala.- lithe are -difficult to mold due to their elasticity which comes into play to deform objects <B> on </B> when they leave the mold. <B> It </B> as a result that until now galalith can only be obtained, -, in the form of plates, blocks or sticks, from which one <B> "</B> is pulled by a suitable mechanical work, - appropriate, cutting or cutting, the desired articles or objects.
The waste thus obtained is significant and hitherto unusable, since it is considered that not all formulated casein can be regenerated.
The present invention relates <B> to </B> a method of manufacturing objects molded with formalin casein, which is -characterized in ique -formalin-casein, made slightly acidic by contact with 'Phenic ap-ide is, after powdering, mixed <B> with </B> an aldehyde, for example, formaldehyde, the mixture then being subjected in molds, <B> to </B> uni-, high pressure and simul- tanknent <B> to,
</B> a temperature of at least <B> 100 Il </B> C. To carry out the process, it is <B>- </B> necessary that the temperature and pressure factors come into play simultaneously and the variations which are subjected <B> to </B> one or the other give -products whose characteristics are slightly -different. It is the combined play of these temperature and pressure variations which enables a wide variety of -products to be obtained, which can be used in the most dif ferent applications.
By treating the materials <B> in </B> a strictly dry state, the total removal of shrinkage is achieved <B> </B>.
The process which is the subject of the invention allows, at the time of molding and because of the temperature used, to produce a phenomenon similar to that known as the name of baking.
The compact material obtained is remarkably hard; it is completely non-flammable and is likely <B> </B> to resist RUX high tem-pera.tur, -s, even in low thicknesses; ell, - can be considered as unbreakable; <U> tomme </U> dielectric, it can be applied even under low thicknesses to high voltage <B> </B> insulation. E Ile is resistant to fatty substances and even <B> to </B> the action of boiling oil and does not undergo any softening under the action of heat unlike other agglomerates known using shellacs or resins.
Any molded object can thus be obtained, just as it is possible to constitute plates or sticks of all shapes or diameters similar to <B> to </B> those sold under the name galalith. You can also mix <B> with </B> these materials with fillers of any kind and make all the color combinations that might be suitable.
The same result is obtained when the powdered material <B> </B> has the action of an aldehyde other than formaldehyde and in particular acetaldehyde, berzaldehyde, crotonaldehyde, etc. .
