externe généralement tendre et un duramen peu imprégnable, les monocotylédones, en particulier les poacées qui ont un chaume ligneux dur et résistant et les palmades dont le stipe est constitué d'un grand nombre de faisceaux libéroligneux. ont une partie interne, souvent méristématique, o des éléments fibro vasculaires ligneux sont entourées d'un tissus de external generally tender and a little impregnable heartwood, the monocots, in particular the poaceae which have a hard and resistant woody stubble and the palmades whose stipe is made up of a large number of liberous bundles. have an internal part, often meristematic, where woody fibro-vascular elements are surrounded by
cellules peu différenciées dont la consistance est comparable au liège. poorly differentiated cells whose consistency is comparable to cork.
Il est difficile de trouver sur le marché un matériau naturel qui allie une très grande légèreté et une bonne résistance mécanique, qui soit isolant phonique et thermique, qui soit It is difficult to find on the market a natural material which combines a very great lightness and a good mechanical resistance, which is sound and thermal insulator, which is
autoextinguible sans émission de fumées toxiques. self-extinguishing without emission of toxic fumes.
Prenons pour exemple le borassus flabelliformnis. Le délignage du stipe penrmet d'obtenir des planches de couleur très foncée, en bois parfait dans la partie périphérique des planches brun clair de dureté moyenne propres à faire du lambris dans une partie médiane, enfin des planches de teinte beige clair plus tendres et très légères dans le coeur Take for example the borassus flabelliformnis. The trimming of the stipe makes it possible to obtain very dark planks, of perfect wood in the peripheral part of the light brown planks of medium hardness suitable for making paneling in a middle part, finally planks of light beige color more tender and very light in the heart

extinguibles sans dégagement de funmées toxiques. Leur très grande légèreté, et leur anrmature naturelle permnnet une utilisation nouvelle dans tous les domaines o ces propriétés sont requises, notamment pour constituer des panneaux d'isolation, pour lieux publics ou extinguishable without release of toxic funmées. Their great lightness, and their natural structure allows new use in all areas where these properties are required, in particular to constitute insulation panels, for public places or
privés, navires, aéronefs, mais aussi, structures en sandwich, par exemple, des skis. private, ships, aircraft, but also, sandwich structures, for example, skis.
A l'état brut ces planches sont difficilement utilisables car le xylème est imprégné d'une sève à haute teneur en saccharose qui subit en quelques heures, dans le milieu ambiant, une importante pollution microbienne par des levures. des moisissures et des In the raw state these boards are difficult to use because the xylem is impregnated with a sap with a high sucrose content which undergoes in a few hours, in the ambient environment, a significant microbial pollution by yeasts. mold and
bactéries lactiques.lactic acid bacteria.
Dans tous les cas la matière première doit ètre séchée. In all cases the raw material must be dried.
Une première solution consiste à introduire les planches dans des séchoirs aussitot après sciage pour ramener leur taux d'humidité au dessous de.%;o idéalement entre. 8 et 19%. Pour une meilleure utilisation, ce traitement peut être complété par trempage préalable dans un insecticide et lfongicide, qu'il s'agisse de pentachlorophénol, d' ammoniums quaternaires de cuivre, fluor, bore, arsenic, de cyperméthrine, de carbamates, etc. Pour éliminer le saccharose il faut pratiquer le dessevage des planches avant séchage aux normes européennes. Ce traitement sera effectué dans une cuve longitudinale Cen tôle galvanisée chaudronnée de 300xO10x100 cm. montée sur une structure de cornières mécano-soudées comprenant une vanne de vidange. On v immerge, dans de l'eau, des planches, écartées par des séparateurs plastiques pour faciliter la dilution; après un premier bain de 2 heures au cours duquel l'eau est brassée par une roue à palettes il est constaté sur des planches d'une section de 15x100 mm. une réduction supérieure à 20% du taux de saccharose; après le premier renouvellement de l'eau de rinçage le taux A first solution consists in introducing the boards into dryers immediately after sawing to bring their humidity level below.%; O ideally between. 8 and 19%. For better use, this treatment can be completed by pre-soaking in an insecticide and fungicide, whether it be pentachlorophenol, quaternary ammoniums of copper, fluorine, boron, arsenic, cypermethrin, carbamates, etc. To eliminate sucrose it is necessary to practice the drying of the boards before drying to European standards. This treatment will be carried out in a longitudinal Cen galvanized sheet metal tank of 300xO10x100 cm. mounted on a structure of mechanically welded angles including a drain valve. Planks are immersed in water, separated by plastic separators to facilitate dilution; after a first bath of 2 hours during which the water is stirred by a paddle wheel it is found on boards with a section of 15x100 mm. a reduction of more than 20% in the sucrose level; after the first renewal of the rinse water the rate
d'élimination va décroissant; un troisième lavage est suffisant pour éviter le bleuissement. elimination is decreasing; a third wash is sufficient to prevent blue stain.

tous les cas, I'élimination de 20% au moins, du saccharose contenu dans les planches. in all cases, the elimination of at least 20% of the sucrose contained in the boards.
Nous avons déja vu que ce dessevage peut être complété, après séchage, par un We have already seen that this drying can be completed, after drying, by a

Selon l'utilisation, le traitement peut être complété, après séchage, par un sel tetrakis, par des citrates de métaux alcalins, par un phosphate de guanylurée, par un Depending on the use, the treatment can be supplemented, after drying, with a tetrakis salt, with alkali metal citrates, with a guanylurea phosphate, with a
pentaborate d'ammonium, par des composés halogénés, etc.. conférant au matériau une meilleure norme d'ignifugation. ammonium pentaborate, by halogenated compounds, etc. giving the material a better fireproofing standard.
Selon l'utilisation, après séchage, le traitement peut rendre le matériau hydrofuge Depending on the use, after drying, the treatment can make the material water-repellent
par imprégnation d'un hydrofuge du type oligomère rnméthylsiloxane ou autre. by impregnating a water repellent of the rnmethylsiloxane or other oligomer type.
Selon l'utilisation, après séchage, le matériau peut recevoir un traitement de surface imperméabilisant et élastique du genre résine de copolymères PVC et alcool polyvinylique. Selon l'utilisation, après séchage, le matériau peut être durci par une imprégnation d'urée formol ou phénol formol ou diallyle phtalate ou métacrylate de méthyle, etc. According to the use, after drying, the material can receive a waterproofing and elastic surface treatment of the resin type of PVC and polyvinyl alcohol copolymers. Depending on the use, after drying, the material can be hardened by impregnating urea formaldehyde or phenol formaldehyde or diallyl phthalate or methyl methacrylate, etc.
Selon l'utilisation, après séchage, le matériau peut être utilisé en sandwich entre deux ou plusieures autres matières. Depending on the use, after drying, the material can be used sandwiched between two or more other materials.
0 Le matériau obtenu, d'une densité de 140 Kgim3 environ, convient pour tous les usages o il est requis des caractéristiques d'isolation thermique et phonique, de bonne 0 The material obtained, with a density of approximately 140 Kgim3, is suitable for all uses where thermal and sound insulation characteristics are required, of good
