procédé de fabrication d'une colle imperméabilisante pour papeteries.
@ Cette invention a pour objet un procédé de fabrication d'une colle susceptible d'être utilisée,dans la fabrication des papiers et cartons,en vue dé les rendre imperméables et d'assurer la rétention,dans les papiers en fabrication, defines matières premières t des charges minérales.
Jusqu* ici, comme cela est bien connu, l'imperméabiliotédespa- piers et cartons a généralement été obtenue par l' addition, aux pâtes à papier en trituration,d'un pourcentage de 'résine dissoute et émulsionnée au moyen de carbonate de soude. On obtient insi un résinate de soude auquel on ajoute ensuite du sulfate d'alumine l'alumine et la résine sont fixées à la fibre tandis que la soude et l'acide sulfurique du sulfate sont éliminés avec les eaux de fabrication.
On sait également qu'on peut faire usage,dans le même but, d'un empois à base de fécule traitée par la soude. On a déjà dans ce but préparé à froid par mélange et travail à la main,!'emplois destiné a etre ajouté aux pâtes à papier pour augmenter la cohé- sion des fibres.
L'invention actuelle est basée également sur l'emploi d'une collé à base de fécule,traitée par la soude caustique,mais se dis- tingue essentiellement des procédés connus jusqu'ici par lin. troduction dans le produit de colles animales,de 'gélatine pat exemple,ces produits étant trmturés et malaxés mécaniquement à chaud jusqu'à obtention d'une gelée visqueuse.
<Desc/Clms Page number 2>
L'expérience montre que,danS ces conditions,c'est à dire sous l'action du malaxage énergique et de l'intervention de la chaleur on obtient avec un minimum de soude,une colle possédant un pou- voir colloïdal et agglutinant particulièrement élevé susceptible de retenir dans de fortes proportions les fibrilles,charges mi- néra.les et couleurs et de donner aux papiers et cartons, par sa plasticité et lors du atinage,une douceur.un poli et un lustra- ge' particulièrement réussis et en marne temps plus de solidité de carteux et de sonnant.
Dans la réalisation pratique de l'invention,on se sert,pour la 'fabrication de produit,d,un malaxeur du genre de celui montré par le dessin ci-joint dans lequel la figure 1 donne une vue en coupe verticale et la figure 2 une vue en plan.
L'appareil représenté est constitué par une cuve 1,de forme cylindrique par exemple, à la partie supérieure de laquell'e est disposé un tamis 2,servant à tamiser l'eau et la soude caustique. introduites dans lacuve. Dans celle-ci est disposé un arbre ver tical 3 mis en rotation par une commande 4 par engrenages rece- vant son mouvement d'un arbre 5 commandé par les poulies motri- ces (folle et fixe) 6.
L'rabre 3 qui repose à sa partie inférieu , re 7 'dans un coussinet 8, porte des bras de malaxage 9 qui coopè- rent avec des cornières 10 disposées suivant des génératrices de la, cuve 1,de façon à contrarier les mouvements de la masse entrai! née par les-bras 9. L'appareil est complétépar un tuyau d'ame- née de vapeur 11 pourvu d'un robinet de réglage 12 et par un thermomètre 13 servent à vérifier la temérature réganant dans l'appareil .A la partie inférieure de la cuve 1 est disposé un robinet de vidange 14 pour l'évacuation de la colle produite. L'a bre 3 est,de préférence,supporté pans le coussinet 8 par une vis 15 servant à le relever en cas d'u sure.
Lors du fonctionnement l'eau et la soude caustique sont intro-, duites dans la cuve 1 par lè tamis 2 pour agir sur les matières amylacées et sur les colles animales de la gélatine par exemple, contenues dans la cuve.
<Desc/Clms Page number 3>
Le mélange est trituré énergiquement par les bras 9 coopérant avec les cornières 10' Sous l'action de la chaleur et du malaxage, qui favorise l'action de la soude, les produits se convertissent en gelée visqueuse et épaisse-les éléments s'hydratent,la gélifica tion des fécules est complète et la colle devient miscible et soluble. Grâce à sa miscibilité lorsqu'elle est utilisée pour l'imperméabilisation des papiers et cartons,elle se disperse dans toutela masse du papier liquide assurant ainsi des résultats particulièrement remarquables.
Dans la composition finale les colles animales ont principale- ment pour résultat de procurer l'imperméabilisation,tandis que les colles de fécules,tout en augmentant cette qualité,contribuent à donner aux papiers de la rigidité et du glaçage. Il s'ensuit que, lorsque c'est principalement l'imperméabilité des papiers que l'on a en vue, 'on fait usage des deux éléments,gélatine et fécule, tan- dis que si c'est la dureté et la résistance des papiers ainsi que le satinage qui sont envisagés,on peut se contenter de la matière amylacée seule, à condition quelle traitement ait été effectué, comme cela a été indiqué ci¯dessus,à chaud et par malaxage mécain@@ que jusquâ production d'une gelée visqueuse et épaisse.

manufacturing process of a waterproofing glue for paper mills.
@ This invention relates to a process for manufacturing an adhesive that can be used in the manufacture of paper and cardboard, with a view to making them impermeable and ensuring retention, in the papers in manufacture, defines raw materials t mineral charges.
Heretofore, as is well known, the waterproofing of planks and boards has generally been obtained by adding to the pulps under trituration a percentage of resin dissolved and emulsified by means of sodium carbonate. A sodium resinate is obtained, to which aluminum sulphate is then added, the alumina and the resin are fixed to the fiber while the soda and sulfuric acid from the sulphate are removed with the manufacturing water.
It is also known that use can be made, for the same purpose, of a starch-based poison treated with soda. For this purpose, it has already been prepared cold by mixing and working by hand, the use intended to be added to paper pulps to increase the cohesion of the fibers.
The present invention is also based on the use of a glue based on starch, treated with caustic soda, but essentially differs from the processes known hitherto by flax. Troduction in the product of animal glues, of 'gelatin for example, these products being trmturé and kneaded mechanically hot until a viscous jelly is obtained.
<Desc / Clms Page number 2>
Experience shows that, under these conditions, that is to say under the action of vigorous mixing and the intervention of heat, one obtains with a minimum of soda, a glue having a particularly high colloidal and agglutinating power. capable of retaining in high proportions the fibrils, mineral fillers and colors and of giving paper and cardboard, by its plasticity and during the processing, a smoothness. a polish and a luster 'particularly successful and marl time more solidity of cardboard and sounding.
In the practical embodiment of the invention, use is made, for the manufacture of the product, of a mixer of the type shown by the accompanying drawing in which Figure 1 gives a view in vertical section and Figure 2 a plan view.
The apparatus shown is constituted by a tank 1, of cylindrical shape for example, in the upper part of which there is a sieve 2, used to sift the water and the caustic soda. introduced into the tank. In this is disposed a vertical shaft 3 rotated by a gear drive 4 receiving its movement from a shaft 5 controlled by the drive pulleys (idle and fixed) 6.
The shaft 3 which rests at its lower part, re 7 'in a pad 8, carries mixing arms 9 which cooperate with angles 10 arranged along generatrices of the tank 1, so as to thwart the movements of the mass entered! born by the arms 9. The apparatus is completed by a steam supply pipe 11 provided with an adjustment valve 12 and by a thermometer 13 are used to check the reganant temperature in the apparatus. of the tank 1 is disposed a drain valve 14 for the discharge of the glue produced. A bre 3 is preferably supported around the pad 8 by a screw 15 serving to raise it in the event of u sure.
During operation, the water and caustic soda are introduced into the tank 1 through the sieve 2 to act on the starchy materials and on the animal glues, for example gelatin, contained in the tank.
<Desc / Clms Page number 3>
The mixture is vigorously triturated by the arms 9 cooperating with the angles 10 'Under the action of heat and mixing, which promotes the action of soda, the products are converted into viscous jelly and thick - the elements hydrate , the starch gelling is complete and the glue becomes miscible and soluble. Thanks to its miscibility when used for waterproofing paper and cardboard, it disperses throughout the mass of the liquid paper, thus ensuring particularly remarkable results.
In the final composition the animal glues mainly result in providing waterproofing, while the starch glues, while increasing this quality, help to give the papers rigidity and glaze. It follows that, when it is mainly the impermeability of the papers that is in view, use is made of the two elements, gelatin and starch, while if it is the hardness and the resistance of the papers. papers as well as the satin finishing which are envisaged, one can be satisfied with the starchy material alone, provided what treatment has been carried out, as indicated above, by hot and by mechanical kneading until production of a thick viscous jelly.
