Description
Elêment calorifuge La présente invention se rapporte à un élément ca lorifuge pouvant être utilisé pour diverses isolations thermiques.
Cet élément est caractérisé en ce qu'il comprend un corps en matériau calorifuge constitué par de la matière plastique expansée et dont au moins une partie de la surface est recouverte d'une couche d'un matériau offrant une grande résistance à la chaleur.
Ce matériau réfractaire peut être de la vermiculite, laine de verre, laine de roche, fibre d'amiante, etc., de telle sorte que la surface, ainsi traitée, puisse sup porter une température nettement supérieure à celle de ramollissement ou de fusion de la matière calori fuge utilisée.
Selon un mode de réalisation préféré, le revête ment dudit corps, qui peut être une plaque ou une coquille en polystyrène expansé, peut être constitué par une couche de vermiculite rapportée sur la face à protéger par collage, flocage, au pistolet, ou tous autres procédés, l'épaisseur de cette couche de vermi- culite pouvant varier en fonction de la température que l'élément calorifuge doit supporter.
Selon une variante, des granules de polystyrène expansé peuvent être entièrement enrobés de vermi- culite ou autre matériau réfractaire.
Sur le dessin annexé donné à titre d'exemple in dicatif mais non limitatif Les fig. 1 et 2 représentent en perspective respec tivement une plaque et une coquille en polystyrène expansé revêtues d'un matériau réfractaire.
En se reportant au dessin et selon un mode de réa lisation, 1 représente une plaque rectangulaire de polystyrène expansé et 2 une coquille semi-tubulaire de même matière.
Ces deux éléments calorifuges comportent, respéc- tivement, sur leur face destinée à être placée au con tact de l'organe chauffant, une couche 3, de vermi- culite par exemple, appliquée par collage, flocage, au pistolet ou autrement.
Selon une variante permettant un bourrage entre deux parois à calorifuger, on utilise des granules de polystyrène expansé enrobés de vermiculite ou autre matériau réfractaire.
Cette couche de vermiculite a pour but d'isoler le polystyrène expansé de la source de chaleur ce qui permet à la plaque, coquille ou aux granules, ainsi traitées de résister à des températures dépassant 1000 C alors que le polystyrène, utilisé tel quel, subit une altération, voire même une destruction, aux en virons de 800 C.
The present invention relates to a heat insulating element which can be used for various thermal insulations.
This element is characterized in that it comprises a body of heat-insulating material constituted by foamed plastic material and of which at least part of the surface is covered with a layer of a material offering great resistance to heat.
This refractory material can be vermiculite, glass wool, rock wool, asbestos fiber, etc., so that the surface, thus treated, can withstand a temperature significantly higher than that of softening or melting of the fuge calorie material used.
According to a preferred embodiment, the coating of said body, which may be a plate or a shell of expanded polystyrene, may consist of a layer of vermiculite attached to the face to be protected by gluing, flocking, spraying, or any other. processes, the thickness of this layer of vermiculite being able to vary according to the temperature which the heat insulating element must withstand.
Alternatively, expanded polystyrene granules can be completely coated with vermiculite or other refractory material.
In the appended drawing given by way of indicative but non-limiting example, FIGS. 1 and 2 represent in perspective respectively a plate and a shell of expanded polystyrene coated with a refractory material.
Referring to the drawing and according to one embodiment, 1 represents a rectangular plate of expanded polystyrene and 2 a semi-tubular shell of the same material.
These two heat-insulating elements comprise, respectively, on their face intended to be placed in contact with the heating member, a layer 3, of vermiculite for example, applied by gluing, flocking, by spraying or otherwise.
According to a variant allowing a stuffing between two walls to be insulated, expanded polystyrene granules coated with vermiculite or other refractory material are used.
The purpose of this vermiculite layer is to insulate the expanded polystyrene from the heat source, which allows the plate, shell or granules, thus treated to withstand temperatures exceeding 1000 C while the polystyrene, used as is, undergoes an alteration, or even destruction, at around 800 C.
