Description
Procédé pour la préparation d'une huile pour l'imprégnation des bois. La présente invention est relative à un procédé pour la préparation d'une huile per mettant l'imprégnation des bois par simple immersion à la pression atmosphérique.
Selon ce procédé, on obtient cette huile d'imprégnation en mélangeant une huile de créosote avec une faible quantité de phénol, en agitant continuellement et en filtrant ce mélange après l'avoir laissé reposer.
L'expérience a montré que lorsqu'an sou met les huiles de créosote à une agitation plus ou moins longue en présence de faibles quantités de phénol, auxquelles peuvent être mélangés d'autres corps tels que le goudron, l'huile légère de houille et le benzol, et que l'on filtre ensuite ce mélange, on obtient dés huiles de créosote qui pénètrent parfaitement les pores des bois à la pression atmosphé rique ordinaire.
En pratique, on peut obtenir de bons résultats dans les conditions suivantes On fait par exemple le mélange suivant
EMI0001.0004
Créosote <SEP> 70,0 <SEP> parties
<tb> Phénol <SEP> (du <SEP> commerce) <SEP> à <SEP> 32 <SEP> % <SEP> 6,0 <SEP> "
<tb> Goudron <SEP> de <SEP> houille <SEP> 9,5
<tb> Huile <SEP> légère <SEP> de <SEP> houille <SEP> 8,0 <SEP> "
<tb> Benzol <SEP> <U>6,5 <SEP> "</U>
<tb> <U>100,0 <SEP> parties</U> Ce mélange est traité pendant environ deux heures. dans une auge pourvue de dis positifs agitateurs.
L'adjonction du phénol a, entre autres, pour effet d'éliminer certains composés péné trant difficilement dans le bois, ou empêchant la pénétration des principes huileux fungicides nécessaires à sa conservation, et d'éliminer de plus, les traces d'ammoniaque, contenues comme impureté dans le goudron de houille. Ces composés sont principalement des paraf fines, ou hydrocarbures saturés de la forme générale C" H2".2 qui sont des constituants des huiles de créosote.
On laisse reposer et on décante ensuite sur un filtre qui est constitué de préférence par une colonne comportant une ou plusieurs couches de coke concassé ou pulvérisé, ou autre charbon. d'absorption. L'huile de créosote ainsi obtenue possède une densité comprise entre 1060 et 1100.
Pour l'imprégnation des bois, il suffit de les y tremper pendant un temps plus ou moins long et le liquide peut être contenu dans une auge ou réservoir ouvert, à la pres sion atmosphérique.
Dans certains cas, on peut chauffer l'huile d'imprégnation jusque vers<B>100'</B> C, mais on peut également opérer à la température ordinaire.
Process for the preparation of an oil for the impregnation of wood. The present invention relates to a process for the preparation of an oil permitting the impregnation of woods by simple immersion at atmospheric pressure.
According to this process, this impregnating oil is obtained by mixing a creosote oil with a small amount of phenol, stirring continuously and filtering this mixture after having allowed it to stand.
Experience has shown that when creosote oils are stirred more or less long in the presence of small amounts of phenol, with which other substances such as tar, light coal oil and other substances can be mixed. benzol, and when this mixture is then filtered, creosote oils are obtained which perfectly penetrate the pores of the woods at ordinary atmospheric pressure.
In practice, good results can be obtained under the following conditions. For example, the following mixture is made
EMI0001.0004
Creosote <SEP> 70.0 <SEP> parts
<tb> Phenol <SEP> (from <SEP> commerce) <SEP> to <SEP> 32 <SEP>% <SEP> 6.0 <SEP> "
<tb> Tar <SEP> from <SEP> coal <SEP> 9.5
<tb> Oil <SEP> light <SEP> of <SEP> coal <SEP> 8.0 <SEP> "
<tb> Benzol <SEP> <U> 6.5 <SEP> "</U>
<tb> <U> 100.0 <SEP> parts </U> This mixture is cured for approximately two hours. in a trough provided with positive agitators.
The addition of phenol has, among other things, the effect of eliminating certain compounds which hardly penetrate into the wood, or preventing the penetration of the oily fungicidal principles necessary for its conservation, and also to eliminate traces of ammonia, contained as an impurity in coal tar. These compounds are mainly paraffins, or saturated hydrocarbons of the general form C "H2" .2 which are constituents of creosote oils.
Allowed to stand and then decanted on a filter which preferably consists of a column comprising one or more layers of crushed or pulverized coke, or other coal. absorption. The creosote oil thus obtained has a density of between 1060 and 1100.
For the impregnation of the wood, it suffices to soak them therein for a more or less long time and the liquid can be contained in an open trough or tank, at atmospheric pressure.
In some cases, the impregnating oil can be heated up to <B> 100 '</B> C, but it is also possible to operate at ordinary temperature.
