Abstract

L'invention a pour objet un dispositif de fabrication d'une mousse autodurcissante,trouvant son application dans le bâtiment,l'exploitation des mines et l'industrie des emballages,comportant un groupe motopropulseur-deux pompes équipées de conduites d'aspiration et de refoule­ ment raccordées à un mélangeur terminé par un éjecteur de mousse.Dans le dispositif selon l'invention les condui­ tes /1,2,6/ de débit des deux composants et de l'air,sont introduites parallèlement entre elles dans un fond /3/ du mélangeur,dont la partie rigide /4/ spumogénique présente la forme d'un tube /5/ et la partie /8/ de durcissement est constituée par une conduite souple /9/,et en ce que les conduites /1,2/ débouchent à même le fond /3/ du mé­ langeur tandis que la conduite /6/ de débit de l'agent de durcissement s'achève enfin dans la conduite souple /9/. The subject of the invention is a manufacturing device of a self-hardening foam, finding its application in construction, mining and industry packages, comprising a powertrain-two pumps fitted with suction and discharge lines connected to a mixer terminated by an ejector In the device according to the invention the conduits tes / 1,2,6 / of flow of the two components and of the air, are introduced parallel to each other in a bottom / 3 / of mixer, of which the rigid / 4 / spumogenic part has the shape of a tube / 5 / and the hardening part / 8 / consists of a flexible pipe / 9 /, and in that the pipes / 1,2 / lead to the bottom / 3 / of the mé languor while the agent flow / 6 / hardening finally ends in the flexible pipe / 9 /.

La solution selon l'invention trouve son application à la fabrication et à enduire une isolation calorifique et contre les bruits,ainsi qu'à revêtir d'une couche de protection la surface de divers matériaux et à protéger les objets emballés. The solution according to the invention finds its application to manufacturing and coating heat insulation and against noise, as well as to coat with a layer of protect the surface of various materials and protect packaged items.
