Description
Cartouches de scellement de boulons d'ancrage comportant un raidisseur interne, et ce raidisseur.Anchor bolt sealing cartridges comprising an internal stiffener, and this stiffener.
L'invention concerne une cartouche améliorée comportant une charge de scellement de boulons d'ancrage dans les galeries de mines, et ouvrages analogues, présentant un raidisseur interne amélioré. The invention relates to an improved cartridge comprising a load for sealing anchor bolts in mine galleries, and the like, having an improved internal stiffener.
On sait, à l'heure actuelle, utiliser un raidisseur interne fait en verre dans les charges de scellement. Celui-ci se présente, généralement, sous une forme tubulaire. Ce tube contient le durcisseur mélange d'un peroxyde organique et de charges inertes minérales ou organiques. It is known, at present, to use an internal stiffener made of glass in the sealing charges. This is generally presented in a tubular form. This tube contains the hardener mixture of an organic peroxide and mineral or organic inert fillers.
Le tube de verre présente les inconvénients suivants - industriellement, il n'est disponible que sous la forme de barres de 1,50 m ; ce qui entraîne souvent des pertes relativement importantes compte tenu de la longueur des charges de scellement. The glass tube has the following disadvantages - industrially, it is only available in the form of 1.50 m bars; which often results in relatively large losses given the length of the sealing charges.
- du point de vue manipulation il est souvent considéré comme dangereux dans le cas d'une rupture au sein de la cartouche.- from a handling point of view, it is often considered dangerous in the event of a rupture within the cartridge.
La Demanderesse a cherché å remplacer le verre par un autre matériau ne présentant pas les inconvénients ci-dessus, et présentant d'autres caractéristiques spécifiques de l'application envisagée - résistance aux solvants aromatiques; le monomère usuel des résines polyester utilisées dans le secteur technique considéré est le styrène ; - fragilité voisine du verre - comportement satisfaisant lors de l'introduction de la tige provoquant la destruction de la cartouche au fond du trou, et le mélange des composants , - possibilités de fabrication industrielle satisfai
sante.The Applicant has sought to replace glass with another material which does not have the above drawbacks, and which has other characteristics specific to the envisaged application - resistance to aromatic solvents; the usual monomer of polyester resins used in the technical sector considered is styrene; - brittleness similar to glass - satisfactory behavior during the introduction of the rod causing the destruction of the cartridge at the bottom of the hole, and the mixing of the components, - possibilities of industrial manufacture satisfied
health.
Les essais ont conduit å s'orienter vers les matières plastiques extrudables. Il a cependant été constaté que, de manière surprenante, toutes les matières plastiques ne convenaient pas, en raison notamment de caractéristiques très insuffisantes de déchiquetage lors de la destruction de la cartouche par la tige à sceller, ce qui conduisait à un mélange très imparfait des constituants de la charge contenus dans la cartouche, et donc à un scellement non satisfaisant
(en particulier, répartition non uniforme du catalyseur dans le mastic).The tests led to a move towards extrudable plastics. However, it has been found that, surprisingly, not all plastics are suitable, in particular because of very insufficient shredding characteristics during the destruction of the cartridge by the rod to be sealed, which led to a very imperfect mixture of the constituents of the charge contained in the cartridge, and therefore to an unsatisfactory seal
(in particular, non-uniform distribution of the catalyst in the sealant).
Ces mauvais résultats ont été enregistrés avec les matériaux suivants :
- polyéthylène chargé de craie,
- polypropylène chargé de talc,
- acétate de cellulose,
- polychlorure de vinyle sans plastifiant,
- poly(méthacrylate de méthyle).These poor results were recorded with the following materials:
- polyethylene loaded with chalk,
- talc-loaded polypropylene,
- cellulose acetate,
- polyvinyl chloride without plasticizer,
- poly (methyl methacrylate).
La Demanderesse a finalement mis au point un raidisseur qui est la combinaison d'un tube de polystyrène "Cristal" et d'une gaine mince db polyamBe "film "). The Applicant has finally developed a stiffener which is the combination of a "crystal" polystyrene tube and a thin sheath db polyamBe "film").
On a utilisé un polystyrène "Cristal" avec 1 à 5 % de polystyràne "choc". "Crystal" polystyrene was used with 1 to 5% "shock" polystyrene.
Les polyamides courants conviennent, et de trams bons résultats ont été obtenus avec le polyamide 6. Common polyamides are suitable, and good results have been obtained with polyamide 6.
On a observé que la combinaison du tube poly styr3ne et du fiLm polyamide conduisait notamment à de bons résultats en ce qui concerne le mélange des composants lors de la destruction de la cartouche. On aurait pu penser au contraire que le film de polyamide perturberait ou retarderait la destruction du tube poly styrone (effet tout à fait connu dans le domaine des verres de sécurité comportant un film plastique) et empêcherait donc l'obtention d'un mélange homogène. It has been observed that the combination of the poly styrene tube and the polyamide film leads in particular to good results as regards the mixing of the components during the destruction of the cartridge. One would have thought, on the contrary, that the polyamide film would disturb or delay the destruction of the poly styrone tube (effect quite known in the field of safety glasses comprising a plastic film) and therefore prevent the production of a homogeneous mixture.
I1 semble au contraire que le film polyamide, en épaisseur de 5 à 60 p, de préférence de 20 à 40 p environ, ait une influence bénéfique sur le déchiquetage, si l'on en juge par l'examen qualitatif des coupes de scellements. On the contrary, it seems that the polyamide film, in thickness from 5 to 60 p, preferably from 20 to 40 p approximately, has a beneficial influence on the shredding, if one judges it by the qualitative examination of the sealing cuts.
Le tube polystyrène pourra présenter une épaisseur de paroi de 0,1 à 0,9, de préférence de 0,4 à 0,6 mm. The polystyrene tube may have a wall thickness of 0.1 to 0.9, preferably 0.4 to 0.6 mm.
Le raidisseur selon l'invention est fabriqué de mandore connue par extrusion simultanée. The stiffener according to the invention is made of known mandora by simultaneous extrusion.
D'autres procédés pourront être envisagés par 1'homme du métier. Other methods can be envisaged by a person skilled in the art.
L'exemple suivant illustre l'invention sans toutefois en limiter la portée. The following example illustrates the invention without however limiting its scope.
EXEMPLE
Dans un trou de diamètre 28 mm, on introduit 3 charges de scellement de 225 cc constituées d'une gaine en polyamide de diamètre 23 mm et d'un tube en polystyr3ne revêtu de polyamide (40 ) de diamètre extérieur 10 mm.EXAMPLE
In a hole with a diameter of 28 mm, three 225 cc sealing charges are introduced, consisting of a polyamide sheath with a diameter of 23 mm and a polystyrene tube coated with polyamide (40) with an outside diameter of 10 mm.
- entre les deux films de polyamide se trouve le mastic
(résine polyester non saturé + charges minérales), - dans le tube en polystyrène se trouve le durcisseur.- between the two polyamide films is putty
(unsaturated polyester resin + mineral fillers), - in the polystyrene tube is the hardener.
Celui-ci peut se présenter sous plusieurs formes
un pulvérulent : péroxyde de benzoyle
et sable,
un bâtonnet solide : péroxyde de benzoyle,
sable, argile et eau,
un produit pâteux : péroxyde de benzoyle,
craie et solvant non aromatique.This can take many forms
a powder: benzoyl peroxide
and sand,
a solid stick: benzoyl peroxide,
sand, clay and water,
a pasty product: benzoyl peroxide,
chalk and non-aromatic solvent.
Ces composants sont tout à fait classiques dans le domaine considéré et donc connus, ainsi que les proportions à utiliser, de l'homme du métier. De tels composants sont par exemple décrits dans les demandes de brevet français nO 73.05477 déposée le 16 février 1973 et nO 76.08306 déposée le 23 mars 1976 au nom de la Société S.A.E.I. CELTITE. These components are entirely conventional in the field considered and therefore known, as well as the proportions to be used, to those skilled in the art. Such components are for example described in the French patent applications No. 73.05477 filed on February 16, 1973 and No. 76.08306 filed on March 23, 1976 in the name of the Company S.A.E.I. CELTITE.
- les extrémités du tube en polystyrène seront bouchées par un mélange, tel que
craie : 80 % paraffine chlorée : 20 %. - the ends of the polystyrene tube will be plugged with a mixture, such as
chalk: 80% chlorinated paraffin: 20%.
On introduit une tige "Wema" (crénelée) de 0 20 mm et de longueur 2,20 mètres avec une vitesse de rotation de 800 à 1000 T/minute et une poussée de 50 kg. A "Wema" (crenellated) rod of 0 20 mm and a length of 2.20 meters is introduced with a rotation speed of 800 to 1000 rpm and a thrust of 50 kg.
Temps de rotation : 40 secondes. Rotation time: 40 seconds.
Temps de prise manuelle : 35 secondes. Manual setting time: 35 seconds.
