Abstract
Description
La présente invention concerne un produit de nettoyage consistant en un mélange de composés chimiques organiques. The present invention relates to a cleaning product consisting of a mixture of organic chemical compounds.
Le produit a pour un but de nettoyer les ustensiles de travail de la mousse polyuréthane durcie utilisée comme isolant. The purpose of the product is to clean the working utensils of the cured polyurethane foam used as insulation.
Dans l'isolation des bâtiments, le polyuréthane est utilisé sous forme de mousse moelleuse expansive à base de 4,4'- diisocyanatediphenylméthane, qui devient solide, à l'air libre, au bout d'une vingtaine de minutes. In the insulation of buildings, polyurethane is used as an expansive soft foam based on 4,4'-diisocyanatediphenylmethane, which becomes solid, in the open air, after about twenty minutes.
Cette mousse de polyuréthane est conditionnée dans des bombes aérosols ou dans des grandes bouteilles sous forte pression sous forme d'une pâte très moelleuse. Elle est mise en oeuvre par injection au moyen de pistolets métalliques. Ces injecteurs, après utilisation ne sont pas réutilisables. Par suite de la solidification rapide de la mousse dans les petites canalisations, il est en effet impossible d'éliminer dans l'outil les quantités résiduelles du matériau. This polyurethane foam is packaged in aerosol cans or in large bottles under high pressure in the form of a very soft paste. It is implemented by injection by means of metal guns. These injectors, after use, are not reusable. Due to the rapid solidification of the foam in the small pipes, it is indeed impossible to eliminate the residual amounts of the material in the tool.
Vu le prix relativement élevé de ces injecteurs-pistolets et l'absence sur le marché d'un produit adéquat de nettoyage, un mélange organique permettant d'atteindre cette objectif a été mis au point. Ce mélange agit en refluidisant et fragilisant la mousse durcie. Given the relatively high price of these gun injectors and the absence of an adequate cleaning product on the market, an organic mixture to achieve this objective has been developed. This mixture acts by refluidizing and weakening the hardened foam.
Ce mélange peut être utilisé selon les discriptions suivantes:
1- La méthode de nettoyage consiste à tremper l'outil dans un récipient, avec environ 500 ml du nettoyant pendant une période donnée. Le récipient utilisé est de préférence fermé pour éviter l'évaporation rapide du mélange. Après la durée indiquée (voir plus loin), la mousse polyuréthane solide redevient souple et fragile; elle peut être nettoyée facilement par frottage avec une brosse dure ou une spatule, etc...This mixture can be used according to the following discriptions:
1- The cleaning method consists in soaking the tool in a container, with about 500 ml of the cleaner for a given period. The container used is preferably closed to prevent rapid evaporation of the mixture. After the indicated time (see below), the solid polyurethane foam becomes flexible and fragile; it can be easily cleaned by rubbing with a hard brush or spatula, etc.
2- Aussi, le nettoyant peut être conditionné dans des bombes aérosols pour le nettoyage rapide des outils avant le durcissement complet de la mousse polyuréthane
3- Si le nettoyage est conditionné dans des bombes aérosols à pas de vis adaptable à des pistolets d'injection, on peut effectuer un nettoyage rapide des canalisations dans les pistolets par injection directe du nettoyant.2- Also, the cleaner can be packaged in aerosol cans for quick cleaning of the tools before complete hardening of the polyurethane foam
3- If the cleaning is packaged in aerosol spray nozzles adapted to injection guns, you can perform a quick cleaning of the pipes in the guns by direct injection of the cleaner.
L'opération de nettoyage doit être effectuer dans un endroit aéré pour éviter le confinement de vapeur organique. The cleaning operation should be carried out in a ventilated area to avoid the confinement of organic vapor.
Des expériences ont été effectuées sur la mousse polyuréthane à base de 4,4'diisocyanatediphenylméthane , nous montrent la posibilité de formuler plusieurs mélanges qui peuvent répondre à nos exigences. Experiments have been carried out on the polyurethane foam based on 4,4'diisocyanatediphenylmethane, we show the posibility of formulating several mixtures that can meet our requirements.
Ces mélanges ont été formés à partir des composés purs suivants:
N, N- diméthylformamide (D.M.F.) I C3H7NO)
Acétone (C3H60)
Tétrahydrofuranne (T.H.F.) { C4H8O i
Méthyléthylcétone (M.E.C.) ( C4HsO)
On a essayé de prendre en considération le facteur de temps qui est, en fait, un facteur important pour déterminer l'efficacité du mélange.These mixtures were formed from the following pure compounds:
N, N-dimethylformamide (DMF) I C3H7NO)
Acetone (C3H60)
Tetrahydrofuran (THF) (C4H8O)
Methyl Ethyl Ketone (MEC) (C4H5O)
An attempt has been made to consider the time factor which is, in fact, an important factor in determining the effectiveness of the mixture.
L'efficacité est présentée içi par le temps nécessaire pour que la mousse polyuréthane solidifiée et traitée par notre nettoyant, soit moelleuse et fragile, ce qui permet un décapage facile. The efficiency is presented here by the time required for the polyurethane foam solidified and treated by our cleaner, is soft and fragile, allowing easy stripping.
Les résultats de notre étude sont présentés de la facon suivante:
I- On a utilisé le M.E.C. dans un mélange (D.M.F + M.E.C.), qui donne, pour une composition de 50% de M.E.C., une bonne efficacité après 6 minutes du traitement.The results of our study are presented as follows:
I-The MEK was used in a mixture (DMF + MEC), which gives, for a composition of 50% of MEK, a good effectiveness after 6 minutes of the treatment.
II- La présence du T.H.F. avec l'acétone pour les compositions entre 25% et 75% en volume de T.H.F., donne toujours une bonne efficacité au bout d'une durée entre 35 et 50 minutes. II- The presence of T.H.F. with acetone for the compositions between 25% and 75% by volume of T.H.F., always gives a good efficiency after a period between 35 and 50 minutes.
III- La présence du D.M.F. avec l'acétone pour les compositions entre 20% et 99% en volume de D.M.F., donne une efficacité supérieure à celle trouvée dans I et II.On présente dans le tableau suivant la composition de D.M.F dans le mélange et l'efficacité traduite par le temps:
III- The presence of DMF with acetone for the compositions between 20% and 99% by volume of DMF, gives an efficiency higher than that found in I and II.Now presented in the following table the composition of DMF in the mixture and efficiency translated by time:
