La présente invention concerne un produit anti-mousse destiné à être répandu sur les pelouses pour éliminer la mousse. The present invention relates to an anti-foam product intended to be spread on lawns to eliminate foam.
On sait qu'il est recommandé d'éliminer la mousse des pelouses afin d'éviter que le gazon soit détruit par la mousse en rendant la pelouse disgracieuse. We know that it is recommended to remove moss from lawns in order to prevent the lawn from being destroyed by moss by making the lawn unsightly.
Pour éliminer cette mousse, on utilise habituellement du sulfate de fer que l'on répand sur la pelouse généralement au printemps. To eliminate this foam, iron sulphate is usually used, which is spread on the lawn generally in the spring.
Le sulfate de fer est commercialisé sous forme de poudre cristallisée de formule chimique : S04 H2,7 H20. Iron sulphate is sold in the form of crystallized powder with the chemical formula: SO4 H2.7 H2O.
Ce produit présente l'avantage d'être efficace en tant qu'anti-mousse, de préserver le gazon et d'être relativement économique. This product has the advantage of being effective as an anti-foam, preserving the lawn and being relatively economical.
Il présente cependant l'inconvénient de salir les terrasses ou les allées dallées de pierres. However, it has the disadvantage of dirtying terraces or stone paved walkways.
En effet, le sulfate de fer au contact de la pierre sous l'effet de l'humidité se transforme en roupie en-laissant sur la pierre une tache rougeâtre disgracieuse surtout sur les pierres de couleur claire. In fact, the iron sulphate in contact with the stone under the effect of humidity transforms into a rupee by leaving on the stone an unsightly reddish spot, especially on light colored stones.
De plus, ces taches de rouille sont très difficiles à nettoyer. L'élimination deuces taches ne peut être réalisée qu'au moyen de produits spéciaux à base d'acide fluorhydrique très délicats à manipuler. In addition, these rust stains are very difficult to clean. These stains can only be removed using special products based on hydrofluoric acid which are very difficult to handle.
Ainsi, lorsque les utilisateurs répandent du sulfate de fer sur leur pelouse, ils doivent prendre des précautions pour éviter que celui-ci tombe sur les terrasses ou les allées. When users spread iron sulphate on their lawns, they must take precautions to prevent it from falling on terraces or driveways.
Cependant, même lorsque ces précautions ont été prises, du sulfate de fer répandu sur la pelouse peut être entraîné par ruissellement des eaux de pluie vers une terrasse ou une allée en provoquant les taches de rouilles évoquées ci-dessus
Le but de la présente invention est de remédier aux inconvénients cidessus en proposant un anti-mousse à base de sulfate de fer n'engendrant aucune tache lors de son contact avec les dalles de pierre. However, even when these precautions have been taken, iron sulphate spilled on the lawn can be caused by rainwater runoff to a terrace or driveway causing the rust spots mentioned above.
The object of the present invention is to remedy the above drawbacks by proposing an anti-foaming agent based on iron sulphate which does not cause any stain when it comes into contact with the stone slabs.
Suivant l'invention, cet anti-mousse a pour formule chimique :
S04 Fe, S04 H2 According to the invention, this defoamer has the chemical formula:
S04 Fe, S04 H2
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
Dans ce composé une molécule de sulfate de fer est liée chimiquement à une molécule d'acide sulfurique, alors que dans le sulfate de fer classique chaque molécule de sulfate de fer est liée à sept molécules d'eau
L'anti-mousse selon l'invention peut être obtenu par la réaction chimique suivante :
S04 Fe, n H20 + S04 H2 = > S04 Fe, S04 H2 + n H20 dans laquelle n est égal dz ou 1. In this compound one molecule of iron sulfate is chemically linked to one molecule of sulfuric acid, while in classic iron sulfate each molecule of iron sulfate is linked to seven molecules of water
The antifoam according to the invention can be obtained by the following chemical reaction:
S04 Fe, n H20 + S04 H2 => S04 Fe, S04 H2 + n H20 in which n is equal to dz or 1.
Le produit de cette réaction est chauffé pour éliminer l'eau. The product of this reaction is heated to remove water.
Afin d'obtenir une réaction complète il est préférable de traiter le sulfate de fer heptahydraté par un léger excès stoechiométrique d'acide sulfurique
On donne ci-après, à titre d'exemple, le mode opératoire de la préparation du produit anti-mousse selon l'invention. In order to obtain a complete reaction it is preferable to treat the iron sulfate heptahydrate with a slight stoichiometric excess of sulfuric acid
The procedure for preparing the anti-foam product according to the invention is given below, by way of example.
On mélangé 27,8 Kg de sulfate de fer heptahydraté sec du commerce, avec 10 Kg d'acide sulfurique concentré. On laisse le mélange réagir En fin de réaction, on obtient tH1 produit solide crystallisé et de l'eau. 27.8 kg of dry commercial iron sulphate heptahydrate are mixed with 10 kg of concentrated sulfuric acid. The mixture is left to react. At the end of the reaction, tH1 crystallized solid product and water are obtained.
On chauffe le mélange ci-dessus pour éliminer l'eau par évaporation
Le produit résiduel sec de formule chimique S04 Fe, S04 H2 pèse environ 25 Kg. The above mixture is heated to remove water by evaporation
The dry residual product of chemical formula S04 Fe, S04 H2 weighs approximately 25 Kg.
Ce produit est utilisable à l'état pulvérulent, tel quel ou mélangé à un engrais, pour éliminer la mousse des pelouses. This product can be used in powder form, as it is or mixed with a fertilizer, to remove moss from lawns.
Les essais ont montré qu'il était tout aussi efficace que le sulfate de fer classique, sans présenter l'inconvénient de tacher les dalles en pierre. Tests have shown that it is just as effective as conventional iron sulphate, without the disadvantage of staining stone slabs.
Selon un autre mode de réalisation de l'invention, on ajoute au produit obtenu un carbonate pour réaliser la réaction suivante
S04 Fe, S04 H2 + C03 M S04 Fe, S04. M + H20 + C02 dans laquelle M désigne deux atomes de potassium (K), un atome de calcium (Ca) ou deux groupements ammonium (NH4) l'eau résiduelle étant éliminée par chauffage. According to another embodiment of the invention, a carbonate is added to the product obtained to carry out the following reaction
S04 Fe, S04 H2 + C03 M S04 Fe, S04. M + H20 + C02 in which M denotes two potassium atoms (K), one calcium atom (Ca) or two ammonium groups (NH4), the residual water being eliminated by heating.
L'ajout de carbonate permet de rendre le produit anti-mousse neutre et aussi de ne pas acidifier le sol. The addition of carbonate makes it possible to make the anti-foam product neutral and also not to acidify the soil.

Pour éviter de chauffer le sulfate de fer heptahydraté en vue d'obtenir un monohydrate, on peut-utiliser-la chaleur produite par la réaction de l'acide sulfurique concentré sur une solution de sulfate de fer heptahydraté suivant le procédé décrit ci-dessous :
On utilise la propriété de l'acide sulfurique concentré de précipiter te sulfate de fer monohydraté à partir d'une solution concentrée de sel heptahydraté, la chaleur de la réaction permettant de sécher le produit obtenu, selon l'équation :
S04Fe, 7H20 + S04H2 = S04Fe, H20 + (S04H2 + 6H20) + calories (Solution) (concentré) (diluée)
L'anti-moûsse peut être répandu manuellement, à condition de protéger les mains avec des gants ou au moyen d'un appareil d'épandage à l'état pulvérulent ou en solution dans l'eau. To avoid heating the iron sulphate heptahydrate in order to obtain a monohydrate, the heat produced by the reaction of concentrated sulfuric acid with a solution of iron sulphate heptahydrate can be used according to the process described below:
The property of concentrated sulfuric acid is used to precipitate iron sulphate monohydrate from a concentrated solution of heptahydrate salt, the heat of the reaction making it possible to dry the product obtained, according to the equation:
S04Fe, 7H20 + S04H2 = S04Fe, H20 + (S04H2 + 6H20) + calories (Solution) (concentrated) (diluted)
The anti-foam can be spread manually, provided that the hands are protected with gloves or by means of a spreading device in powder form or in solution in water.
En raison de ses avantages, l'anti-mousse selon l'invention peut être utilisé sans précautions particulières pour éliminer la mousse sur les joints engazonnés compris entre les dalles de pierre. Because of its advantages, the anti-foam according to the invention can be used without special precautions to remove the foam on the grassed joints between the stone slabs.
