Description
PROCEDE D'EXTRACTION DE
CHEWING-GUM SUR TOUS SUPPORTS
ET PLUS PARTICULIEREMENT SUR LES
SUPPORTS POREUX
La Présente invention concerne un procédé pour extraire des chewing-gums sur tous les supports et plus particulièrement sur les supports pierreux et poreux tel que le ciment granit, pavés auto-blocants mais aussi les moquettes, textiles et tous thermoplastiques...........
On connaît déjà des compositions nettoyantes permettant d'enlever des chewing-gums, ces compositions sont généralement des bombes cryogénies dites bombes de froid, mais elles durcissent les chewing-gums et ensuite il faut les casser et il en résulte des inconvénients majeurs : En cassant les chewing-gums durcit, on détériore le supports poreux et on laisse des résidus de gomme ainsi que des spectres dans les supports poreux et pierreux.
Ces spectres sont dus à la migration de la gomme dans la porosité de la pierre. Une autre technique actuellement utilisée pour enlever les chewinggums consiste à les racler avec un engin motorisé (Krama) une fine lame racle le chewing-gum sur le support mais là encore nous étalons ou laissons un spectre de pigmentation sur le support, de plus ce procédé est incompatible avec des supports tels que : moquette, thermoplastique, textile. Une autre technique consiste actuellement à utiliser des nettoyeurs à haute pression et à eau chaude, mais là encore nous ramollissons la gomme et laissons un spectre sur le support de plus ce procédé est encore incompatible avec des supports tels que moquette, thermoplastique et textile car nous délaierions le support avec l'eau et se pression de celle-ci.
<EMI ID=1.1>
pouvant avoir un diamètre de 1,6mm, 3,2mm et 6,4mm. Ces cristaux sont amenés au travers d'un Venturi et projeté sur le chewing-gum entre 5 et 6 bars de pression à l'aide d'un pistolet . Le choc thermique devrait normalement faire disparaître le chewing-gum, mais là encore plusieurs inconvénients majeurs subsistent tels que spectres encore une fois sur le support, sur les revêtements moquette, textile et thermoplastique, le choc thermique détruit les fibres des textiles et moquettes ou casse les plastiques. De plus, le Venturi dégage 135 décibels et des gaz carboniques ce qui n 'est pas sans danger.
L'invention vise donc à pailler à tous ces inconvénients. Un but de l'invention est de fournir un procédé pour enlever les gommes à mâcher sans modifier l'aspect superficiel des supports. Un autre but de l'intervention est de fournir un procédé pour enlever les gommes à mâcher sur des surfaces pierreuses et poreuses sans laisser de pigmentation résiduelle sur le support. Un troisième but de l'invention est de fournir un procédé d'enlèvement de gomme à mâcher qui soit aussi efficace sur des surfaces pierreuses, moquettes. thermoplastiques et tous textiles.
Un quatrième but de l'invention est de fournir un procédé d'enlèvement des gomme à mâcher ne nécessitant qu'une main d'oeuvre réduite et un faible coût de matière nettoyante. Un cinquième but de l'intervention est de fournir un procédé d'enlèvement des gommes à mâcher non bruyant et sans changer aussi bien pour l'utilisateur que pour l'environnement. A cet effet l'intervention concerne un procédé pour enlever les chewing-gums déposés sur des supports poreux et pierreux consistant en une première étape à pulvériser sur le chewing-gum un gel contenant un mélange de solvants carbonés, au moins un solvant polaire et au moins un gélifiant. En une seconde étapes à laisser sécher le gel et en une troisième étape à projeter un composé sur le chewing-gum.
Selon le mode de réalisation de l'intervention, on projette sur le chewinggum extrait du support par le séchage du gel des particules de solide. De préférence, on projette sur le chewing-gum des cristaux de glucose monohydratés qui peuvent avoir un diamètre de 0,500mm ou 0,250mm ou, 0,100mm, les particules ont eu en outre une très légère action de sablage ce qui entraîne en même temps un nettoyage du support ou se trouve la gomme à mâcher. On peut tout aussi bien projeter des cristaux de dextrose (sorbitol) de 0,800mm à 0,20mm de diamètre, ces cristaux ont pour avantage d'être des produits alimentaires qui peuvent être évacués au tout à l'égout sans aucune nuisance pour l'environnement.
Exemple : On dépose sur un chewing-gum collé sur un support pierreux un gel qui est composé de :
- Essence C comportant des composés paraffiniques en C6 C7 et des <EMI ID=2.1>
étant inférieurs à 5 % en volume.
<EMI ID=3.1> composéscycloparaffiniques en C7 C8 et C10 la teneur aromatique étant inférieure à 5 % en volume. - Essence A comportant des composés paraffiniques en C4 C7 C8 et des composés cycloporaffiniques en C4 C7 et C8 et des composés isoparaffiniques en C4 et C 10.
- Dioxyde de silicium : finement divisé 15 % en volume.
- Ethanol : 10 % en volume.
- Dipropylène monomélhyglycol éther 10 % en volume.
On laisse sécher le gel entre 10 et 15 minutes. Celui-ci en séchant va tirer le chewing-gum du support pour éviter tous résidus ou spectre de pigmentation. On projette ensuite des cristaux solides de sorbitol ou de glucose. Ces cristaux sont amenés au travers d'un Venturi et projetés sur le chewing-gum celui-ci est complètement dissous.
A l'aide de ce procédé, suivant l'invention, on obtient comme déchet qu'une fine poussière en quantité négligeable et le procédé, suivant l'invention, est non polluant.
Il est à noter quand ce qui concerne les supports textiles, moquette et thermoplastique il suffit de frotter avec un chiffon sec après que le gel soit sec et il n'est donc pas besoin de projeter des cristaux solides.
EXTRACTION PROCESS
CHEWING GUM ON ALL MEDIA
AND MORE PARTICULARLY ON
POROUS SUBSTRATES
The present invention relates to a process for extracting chewing gum on all supports and more particularly on stony and porous supports such as granite cement, self-blocking pavers but also carpets, textiles and all thermoplastics ... .....
Cleaning compositions are already known which make it possible to remove chewing gum, these compositions are generally cryogenic bombs known as cold bombs, but they harden the chewing gum and then they have to be broken and this results in major drawbacks: By breaking the chewing gums hardens, the porous supports are deteriorated and gum residues are left as well as spectra in the porous and stony supports.
These spectra are due to the migration of gum in the porosity of the stone. Another technique currently used to remove chewing gum consists in scraping them with a motorized machine (Krama) a fine blade scrapes the chewing gum on the support but here again we calibrate or leave a spectrum of pigmentation on the support, more this process is incompatible with substrates such as: carpet, thermoplastic, textile. Another technique is currently to use high pressure cleaners and hot water, but again we soften the gum and leave a spectrum on the support more this process is still incompatible with supports such as carpet, thermoplastic and textile because we would loosen the support with the water and get pressure from it.
<EMI ID = 1.1>
can have a diameter of 1.6mm, 3.2mm and 6.4mm. These crystals are brought through a Venturi and sprayed onto the chewing gum between 5 and 6 bars of pressure using a gun. The thermal shock should normally make the chewing gum disappear, but here again several major drawbacks remain such as spectra once again on the support, on carpet, textile and thermoplastic coatings, thermal shock destroys the fibers of textiles and carpets or breaks plastics. In addition, the Venturi gives off 135 decibels and carbon dioxide, which is not without danger.
The invention therefore aims to mulch with all these drawbacks. An object of the invention is to provide a method for removing chewing gum without modifying the surface appearance of the supports. Another object of the intervention is to provide a process for removing chewing gum from stony and porous surfaces without leaving residual pigmentation on the support. A third object of the invention is to provide a method of removing chewing gum which is also effective on stony surfaces, carpets. thermoplastics and all textiles.
A fourth object of the invention is to provide a method of removing chewing gum requiring only reduced labor and a low cost of cleaning material. A fifth goal of the intervention is to provide a process for removing chewing gum that is not noisy and does not change for the user or the environment. To this end, the intervention relates to a process for removing chewing gum deposited on porous and stony supports, consisting of a first step of spraying on the chewing gum a gel containing a mixture of carbonaceous solvents, at least one polar solvent and minus a gelling agent. In a second step to let the gel dry and in a third step to spray a compound on the chewing gum.
According to the embodiment of the intervention, solid particles are sprayed onto the chewing gum extracted from the support by drying the gel. Preferably, monohydrate glucose crystals are projected onto the chewing gum, which may have a diameter of 0.500 mm or 0.250 mm or, 0.100 mm, the particles have also had a very slight sanding action, which at the same time results in a cleaning of the support where the chewing gum is located. We can just as well project dextrose crystals (sorbitol) from 0.800mm to 0.20mm in diameter, these crystals have the advantage of being food products which can be evacuated to the main sewer without any harm to the environment.
Example: A gel which is composed of: A chewing gum stuck on a stony support is deposited
- Essence C comprising paraffinic compounds in C6 C7 and <EMI ID = 2.1>
being less than 5% by volume.
<EMI ID = 3.1> encycloparaffinic compounds in C7 C8 and C10 the aromatic content being less than 5% by volume. - Essence A comprising C4 C7 C8 paraffinic compounds and C4 C7 and C8 cycloporaffinic compounds and C4 and C 10 isoparaffinic compounds.
- Silicon dioxide: finely divided 15% by volume.
- Ethanol: 10% by volume.
- Dipropylene monomelhyglycol ether 10% by volume.
The gel is left to dry for 10 to 15 minutes. This one when drying will pull the chewing gum from the support to avoid any residue or spectrum of pigmentation. Then solid crystals of sorbitol or glucose are projected. These crystals are brought through a Venturi and sprayed onto the chewing gum, which is completely dissolved.
With the aid of this process according to the invention, a fine dust in negligible quantity is obtained as waste and the process according to the invention is non-polluting.
It should be noted that when it comes to textile, carpet and thermoplastic supports it is enough to rub with a dry cloth after the gel is dry and there is therefore no need to project solid crystals.
