Abstract

The procedure is used for the manufacture of insulating material from waste wood. It comprises crushing waste wood from recycled pallets, sawdust or all types of waste wood. The waste woods are mixed with cement and plaster and water added to the mixture. The mixture is then moulded and then extracted after a short time lapse.

Description

La présente invention a pour objet un procédé de fabrication de matériaux isolants et de plots pour palettes de manutention à partir de déchets de bois.The subject of the present invention is a method of manufacture of insulating materials and pads for pallets handling from wood waste.

Le procédé selon l'invention permet d'utiliser tous les déchets de bois et dérivés du bois, à savoir les déchets de bois proprement dits, les déchets de papeterie et les déchets de déchetterie.The method according to the invention makes it possible to use all wood and wood-based waste, namely waste wood proper, stationery waste and waste from recycling center.

Les déchets de bois proprement dits sont les déchets qui proviennent de scieries ou du recyclage de palettes de bois. Il peuvent prendre la forme de copeaux, de sciure, ou de morceaux de bois de très petites dimensions.Wood waste proper is the waste from sawmills or the recycling of wooden pallets. They can take the form of chips, sawdust, or very small pieces of wood.

Les déchets de papeterie consistent en les déchets de pulpe de bois qui proviennent de cette industrie.Stationery waste consists of waste of wood pulp from this industry.

Les déchets de déchetterie comprennent tous les déchets de bois agglomérés et de bois mélaminés, qui ne peuvent être brûlés en raison des colles qu'ils contiennent.Waste from recycling centers includes all chipboard and melamine-based wood waste, which does not can be burned due to the glues they contain.

Le procédé selon l'invention permet de mettre en oeuvre tous ces déchets de bois dans leur état, sans aucun traitement chimique préalable.The method according to the invention makes it possible to set up work all this wood waste in their state, without any preliminary chemical treatment.

Les déchets de bois peuvent ainsi être utilisés secs ou humides, après un broyage destiné à réduire leurs dimensions de manière qu'elles ne dépassent pas environ 1cm.Wood waste can thus be used dry or wet, after grinding to reduce their dimensions so that they do not exceed approximately 1cm.

Le procédé selon l'invention consiste à mélanger les déchets de bois avec un liant constitué d'un mélange de ciment, de plâtre et d'eau, à transférer le mélange obtenu dans des moules et à le démouler après un temps très court.The method according to the invention consists in mixing wood waste with a binder consisting of a mixture of cement, plaster and water, to transfer the mixture obtained in molds and unmolding after a very short time.

Le liant mis en oeuvre dans le procédé selon l'invention comprend du ciment et du plâtre en proportions sensiblement égales, et de l'eau à raison de 30 à 50 % en volume.The binder used in the process according to the invention comprises cement and plaster in proportions substantially equal, and water at a rate of 30 to 50% in volume.

Selon la dureté du produit que l'on veut obtenir, les proportions des différents constituants peuvent varier dans d'assez larges limites, les déchets de bois étant mis en oeuvre dans des proportions qui varient en sens inverse de la dureté du produit fini.Depending on the hardness of the product that we want to obtain, the proportions of the various constituents may vary within fairly wide limits, wood waste being disposed of work in proportions that vary in opposite direction to the hardness of the finished product.

Ainsi dans le cas où l'on veut obtenir un matériau isolant les déchets de bois sont mis en oeuvre à raison d'environ 60 à 80 % en volume, le reste étant constitué du liant.So in the case where we want to obtain a material insulating wood waste is used rightly about 60 to 80% by volume, the rest being made up of binder.

Dans ce cas, les déchets de bois mis en oeuvre peuvent comprendre des déchets de déchetterie, mais ils peuvent aussi consister en un mélange de déchets de bois proprement dits et de déchets de papeterie.In this case, the wood waste used may include waste from a recycling center, but they may also consist of a mixture of wood waste proper and stationery waste.

Dans le cas où l'on veut obtenir des plots pour palettes de manutention, les déchets de bois sont mis en oeuvre à raison d'environ 30 à 60 % en volume, le produit obtenu présentant une dureté plus grande du fait de sa plus grande teneur en ciment et en plâtre.In the case where one wants to obtain plots for handling pallets, wood waste is put in works at a rate of about 30 to 60% by volume, the product obtained having a greater hardness due to its greater high content of cement and plaster.

Dans ce cas, les déchets de bois mis en oeuvre comprennent une proportion non négligeable de déchets de déchetterie, et au moins 15 % de tels déchets.In this case, the wood waste used include a significant proportion of waste from recycling center, and at least 15% of such waste.

Dans l'un et l'autre cas, les proportions relatives des différents déchets peuvent varier dans de larges limites.In either case, the relative proportions different wastes can vary within wide limits.

La première étape du procédé selon l'invention est réalisée par mélange des déchets de bois avec le ciment et le plâtre, puis addition d'eau au mélange ainsi constitué.The first step of the process according to the invention is made by mixing wood waste with cement and plaster, then addition of water to the mixture thus formed.

L'eau est de préférence ajoutée au mélange après avoir été légèrement préchauffée jusqu'à environ 30°C, de manière à accélérer la prise du ciment et à permettre un gain de temps au démoulage du produit fini.Water is preferably added to the mixture after have been slightly preheated to around 30 ° C, so as to accelerate the setting of the cement and to allow a gain of time taken to unmold the finished product.

Ainsi avec 30 % d'eau à 30°C le démoulage peut être réalisé au bout de 3 minutes.So with 30% water at 30 ° C, the mold release can be done after 3 minutes.

Le mélange obtenu est introduit dans des moules de formes et de dimensions adaptées au produit que l'on désire obtenir.The mixture obtained is introduced into molds of shapes and dimensions adapted to the product you want get.

Dans le cas de plots de palettes le mélange de déchets de bois et de liant est moulé de préférence dans des moules cylindriques, mais il peut l'être aussi dans des moules cubiques ou parallélépipédiques.In the case of pallet blocks the mixture of wood and binder waste is preferably molded in cylindrical molds, but it can also be in cubic or parallelepiped molds.

Dans le cas de matériaux isolants, le mélange de déchets de bois et de liant est moulé dans des moules parallélépipédiques de dimensions choisies, de manière à fournir des plaques, des briques, des moellons, ou autres. In the case of insulating materials, the mixture of wood waste and binder is molded into molds parallelepiped of selected dimensions, so that provide plates, bricks, rubble, or other.

Dans l'un et l'autre cas on mélange les constituants dans un mélangeur classique pendant 5 à 10 minutes, puis on l'introduit dans les moules.In both cases we mix the constituents in a conventional mixer for 5 to 10 minutes, then introduce it into the molds.

Le démoulage des produits finis, ainsi qu'il a déjà été dit, peut être effectué après un laps de temps très court, de l'ordre de 3 à 10 minutes, ce qui constitue un avantage appréciable en gain de temps.The demolding of finished products, as it has already been said, can be done after a very short period of time short, in the order of 3 to 10 minutes, which constitutes a appreciable advantage in saving time.

D'autres avantages et caractéristiques de la composition selon l'invention ressortiront plus clairement à la lecture des exemples ci-après qui en décrivent deux modes de réalisation appliqués, l'un à la fabrication de plots de palettes et l'autre à la fabrication d'un matériau isolant.Other advantages and features of the composition according to the invention will emerge more clearly at reading the examples below which describe two modes of applied designs, one for the manufacture of studs pallets and the other to the manufacture of an insulating material.

Au bout de 3 minutes on peut démouler les plots, qui présentent une dureté et un taux d'humidité autorisant leur stockage. Après séchage dans un espace clos sec pendant environ une semaine les plots peuvent être utilisés.After 3 minutes you can unmold the studs, which have a hardness and a humidity level allowing their storage. After drying in a dry closed space for about one week the studs can be used.
