Description

Procédé de fabrication de panneaux isolants, thermiques et acoustiques, et absorbants phoniques et panneaux réalisés suivant le procédé. Method for manufacturing insulating, thermal and acoustic panels, and sound absorbing panels and panels produced according to the method.
La présente invention est relative à des panneaux iso¬ lants fabriqués à partir de matières premières recy¬ clées ou â l'état noble constituées de fibre de cellu¬ lose et de déchets végétaux agglomérés et plus particu¬ l èrement de pa lle et de papier en vrac ou en balles provenant de récoltes sélectives.The present invention relates to insulating panels made from recycled raw materials or in a noble state made up of cellulose fiber and agglomerated plant waste and more particularly of paper and paper. in bulk or in bales from selective crops.
La fabrication de ce type de panneaux, suivant le bre¬ vet EP-A-0 084 917, se fait par une seule opération de mise en forme à très basse pression, de l'ordre de 1 Kg/cmZ, d'une pâte provenant de la préparation des fibres de cellulose et des déchets végétaux mêlés à une quanti tué d'eau appropriée dans une machine ap¬ pelée préformeuse. Cette mise en forme est suivie d'un séchage dans un four continu laissant une quantité de cavités d'air destinées à donner au panneau les qualités requises.The manufacture of this type of panels, according to the patent EP-A-0 084 917, is done by a single shaping operation at very low pressure, of the order of 1 Kg / cmZ, of a paste from the preparation of cellulose fibers and plant waste mixed with a suitable amount of water in a machine called a preforming machine. This shaping is followed by drying in a continuous oven leaving a quantity of air cavities intended to give the panel the required qualities.
L'objet de l'invention est d'apporter au procédé tel que décrit ci-dessus des caractéristiques nouvelles améliorant les diverses phases du procédé et permet- tant d'obtenir un matériau autoportant, sec, non cas¬ sant, feutré, non déformé et résistant à un effort de compression de 160 N/m2 avec, une déformation maxi¬ male de 10 %.The object of the invention is to provide the process as described above with new characteristics improving the various stages of the process and allowing as long as a self-supporting, dry, non-cas¬ ing, felted, non-deformed material resisting a compressive force of 160 N / m2 with, a maximum deformation of 10%.
Pour atteindre ce but le procédé de fabrication de panneaux isolants suivant L'invention est caractérisé en ce que :To achieve this aim, the process for manufacturing insulating panels according to the invention is characterized in that:
1° La pâte homogénéisée provenant d'un doseur est ame¬ née dans la préformeuse (1) sur une toile sans fin de formation (3), du type foile de formation de pape¬ terie, servant success vement au support et à l'égou- tage de la pâte lors du pressage et du préformage et de moyen de manutention du panneau préformé pour son évacuation hors de la préformeuse (1) ;1 ° The homogenized dough coming from a dispenser is fed into the preforming machine (1) on an endless forming cloth (3), of the foamed papermaking type, serving successively for the support and the draining the dough during pressing and preforming and handling means of the preformed panel for its evacuation from the preforming machine (1);
2° Le panneau préformé est introduit dans un four tun¬ nel (5) à percussion double face. L'air chaud étant soufflé sur les deux faces du panneau à sécher d'une manière forcée et très uniforme à une température com¬ prise entre 185° C et 200° C.2 ° The preformed panel is introduced into a tunnel oven (5) with double-sided percussion. The hot air being blown on both sides of the panel to be dried in a forced and very uniform manner at a temperature between 185 ° C and 200 ° C.
Suivant l'invention encore Le panneau, séché et calibré automatiquement, recouvert sur chaque face de colle et d'une couche de carton, est introduit dans une presse chauffante qui, s ultanément, fait durcir La colle et réalise un défoncement sur le périmètre du panneau.According to the invention also The panel, dried and automatically calibrated, covered on each face with adhesive and a layer of cardboard, is introduced into a heating press which, subsequently, hardens the adhesive and produces a knockout on the perimeter of the sign.
D'autres caractéristiques ressortiront de La descrip- tion qui suit, sur la base des dessins annexés montrant en :Other characteristics will emerge from the following description, based on the appended drawings showing in:
Figures 1A et 1B, en élévation, les phases principales du schéma de fonctionnement, et Figure 2 une vue partielle à plus grande échelle de la presse chauffante.Figures 1A and 1B, in elevation, the main phases of the operating diagram, and Figure 2 a partial view on a larger scale of the heating press.
Un panneau suivant l'invention est fabriqué au départ, par exemple, des matières suivantes : paille, papier en vrac ou en balles, eau du réseau et eau d'égouttage, copeaux recyclés provenant du calibrage et de l'usinage.A panel according to the invention is produced from, for example, the following materials: straw, loose or bale paper, mains water and draining water, recycled chips from calibration and machining.
A partir de ces matières la pâte est préparée dans un pulpeur, homogénéisée et envoyée ensuite à un doseur alimentant une préformeuse 1, dont le plateau mobile 2 surmonte une toile sans fin de formation 3, du type toile de formation de papeterie. Le plateau mobi le 3, actionné par des vérins, coulisse vers le bas j us- qu'à ce que la pression requise, de l'ordre de 1,1Kg/cm2 à 4 Kg/cm2, soit atteinte. La toile 3 sert au sup¬ port de La pâte et à son égouttage Lors du pressage et du préformage et encore de moyen de manutention du panneau préformé pour l'évacuer hors de La préfor- meuse et le transférer rapidement sur un transporteur 4 à deux vitesses par l'intermédia re d'un ascenseur- descenseur 4'.From these materials, the pulp is prepared in a pulper, homogenized and then sent to a doser feeding a preformer 1, the movable plate 2 of which overcomes an endless forming fabric 3, of the stationery forming fabric type. The mobi le 3 plate, actuated by jacks, slides downwards until the required pressure, of the order of 1.1 kg / cm2 to 4 kg / cm2, is reached. The canvas 3 is used for supporting the dough and for draining it during pressing and preforming and also as a means of handling the preformed panel to evacuate it from the preforming machine and quickly transfer it to a conveyor 4 to two speeds via a 4 'elevator-descender.
La toile 3 est entraînée par des cylindres 1 ' per et- tant par un moyen approprié de régler son défilement et son centrage. Ces cylindres 1 ' sont pourvus d'un système de nettoyage par raclage et aspersion d'eau. Afin de répartir les tensions de compression sur la toile de formation 3 une tôle perforée intermédiaire 3' est fixée sur la gr lle rapportée de la préformeuse 1 et ladite toile 3 glisse dessus.The fabric 3 is driven by cylinders 1 'per- tant by an appropriate means to adjust its running and centering. These cylinders 1 'are provided with a cleaning system by scraping and spraying water. In order to distribute the compression stresses on the forming fabric 3, an intermediate perforated sheet 3 ′ is fixed to the added mesh of the preformer 1 and said fabric 3 slides over it.
Le transporteur à deux tesses 4 ntroduit lentement le panneau préformé dans le four tunnel 5, équipé de plusieurs convoyeurs à étages permettant une production sur plusieurs niveaux parallèles 6. Le séchage dans le four est réalisé dans des conditions répétitives très précises visant à éliminer un pourcentage d'eau bien défini dans le panneau préformé de L'ordre de 65 % à 75 % par rapport au poids total du gâteau. Cette eau, après séchage, laisse une quantité de cavités d'air donnant au panneau ses qualités thermiques et acoustiques ainsi que sa rigidité feutrée. Le four continu fonctionne à une température comprise entre 185° C et 200° C et L'air chaud est distribué sur Les deux .faces du panneau d'une manière forcée et très uniforme à une vitesse se situant entre 13 m/sec et 18 m/sec. Le temps de séchage dépendra de l'épaisseur du panneau. Les conditions requises pour le séchage permettent d'obtenir un traitement optimal du matériau et de conserver ses qualités tout le long de la fabrica¬ tion.The two-braided conveyor 4 slowly introduces the preformed panel into the tunnel oven 5, equipped with several stage conveyors allowing production on several parallel levels 6. The drying in the oven is carried out under very precise repetitive conditions aimed at eliminating a well-defined percentage of water in the preformed panel of the order of 65% to 75% relative to the total weight of the cake . This water, after drying, leaves a quantity of air cavities giving the panel its thermal and acoustic qualities as well as its felted rigidity. The continuous oven operates at a temperature between 185 ° C and 200 ° C and the hot air is distributed on both sides of the panel in a forced and very uniform manner at a speed between 13 m / sec and 18 m / sec. The drying time will depend on the thickness of the panel. The conditions required for drying make it possible to obtain optimal treatment of the material and to preserve its qualities throughout the manufacture.
Les panneaux secs sont déchargés à partir d'un trans- porteur 7 à deux vitesses (ascenseui—descenseur 7') automatiquement sur palettes, ou bien ils sont introduits directement par un convoyeur à bande 8 dans une cali- breuse double face 9, où le panneau est calibré et poncé automatiquement.The dry panels are unloaded from a two-speed conveyor 7 (elevator-descender 7 ') automatically on pallets, or they are introduced directly by a belt conveyor 8 into a double-sided caliper 9, where the panel is calibrated and sanded automatically.
Le panneau calibré est alors envoyé sur une paletti- seuse, ou bien à L'encollage 10 et au recouvrement 11 par une couche de carton sur chaque face avant d'être introduit dans une presse chauffante 12, qui fait dur- cir la colle. Simultanément, un défoncement sur le périmètre du panneau est réalisé dans cette presse chauffante 12. Les bords sont amincis par compression sous forme d'un chanfrein d'une largeur de 4 cm à 6cm et d'une profondeur de 2 mm à 4 mm sur Les quatre côtés du panneau. Ceci permet à l'utilisateur de solidariser les joints des panneaux d'une manière toujours étanche et solide à l'aide d'une bande de fibre de verre collée dans Le creux créé par Les chanfreins de deux panneaux juxtaposés. La finition se fait alors parfaitement à l'aide d'enduit de rebouchage et de finition.The calibrated panel is then sent to a pallet, or else to the gluing 10 and to the covering 11 by a layer of cardboard on each face before being introduced into a heating press 12, which hardens the glue. Simultaneously, a knockout on the perimeter of the panel is carried out in this heating press 12. The edges are thinned by compression in the form of a chamfer with a width of 4 cm to 6cm and a depth of 2 mm to 4 mm on The four sides of the panel. This allows the user to join the joints of the panels always in a tight and solid way using a strip of fiberglass glued in the hollow created by the chamfers of two juxtaposed panels. The finishing is then done perfectly using filling and finishing plaster.
La réalisation du chanfrein dans la presse chauffante 12 destinée à coller le revêtement final du panneau est représentée en figure 2 montrant le plateau chauf- fant fixe 13 avec cale d'épaisseur 14, le plateau chauf¬ fant mobile 15 monté sur vérins hydrauliques 16 et pourvu d'une contre-forme 17 pour le chanfrein, le panneau 18 avec la colle 19 et Le revêtement 20. L'amincissement des bords du panneau et La polymérisation de la colle pour le collage du revêtement se font en une seule opération de pressage à chaud.The embodiment of the chamfer in the heating press 12 intended to bond the final coating of the panel is shown in FIG. 2 showing the fixed heating plate 13 with a shim 14, the mobile heating plate 15 mounted on hydraulic cylinders 16 and provided with a counterform 17 for the chamfer, the panel 18 with the adhesive 19 and the coating 20. The thinning of the edges of the panel and the polymerization of the adhesive for bonding the coating are carried out in a single pressing operation hot.
A sa sortie de la presse chauffante le panneau est scié d'équerre sur les quatre côtés, mis sur palette et stocké.On leaving the heating press, the panel is sawn square on all four sides, put on a pallet and stored.
Comme matières premières destinées à la fabrication des panneaux on a cité dans le préambule la cellulose et les déchets végétaux. Par cellulose on entend dé- signer soit la cellulose provenant de vieux papiers mêlés à partir de récoltes sélectives, défibrés à l'eau dans un pulpeur conventionnel pour former une pâte, soit la cellulose produite à partir de vé-gétaux tels que papyrus, bagasses de cannes à sucre, bois, feui lles de bananiers et tous végétaux fibreux du même type, défibrés pour former une pâte.As raw materials for the manufacture of panels, cellulose and plant waste have been mentioned in the preamble. By cellulose is meant either cellulose from old paper mixed from selective crops, defibrated with water in a conventional pulper to form a pulp, or cellulose produced from vegetable crops such as papyrus, bagasse sugar cane, wood, banana leaves and all fibrous plants of the same type, defibrated to form a paste.
Par déchets végétaux on entend désigner des matières végétales considérées comme résidus de fabrication, telles que parche de café, son, balle de riz et toutes autres écorces de grains, paillettes de céréales et de riz, sciures et copeaux de bois. By vegetable waste is meant plant materials considered as manufacturing residues, such as coffee parch, bran, rice husk and all other grain husks, grain and rice flakes, sawdust and wood shavings.
