摘要:
The invention relates to a coating material (1) which is laminated and which is intended for insulation systems (7) for installation members, such as pipes, tanks and ventilation ducts. According to the invention, a surface of the insulation system (7) must be covered by the coating material (1). The coating material (1) comprises a first layer in the form of an outer foil (3), e.g. aluminium foil, having a thickness of between 20 and 100 µm, preferably between 30 and 60 µm, and a plastic layer (4) which is disposed between the first foil layer (3) and the surface of the insulation system.

A process for preparing a fiberglass insulation product, including the steps of: (a) providing a layer of fire-retardant kraft paper, (b) coating the fire-retardant kraft paper layer with from 2 to 10 pounds of HDPE or of polypropylene per 3000 square feet of the paper to form an HDPE-fire-retardant kraft laminate or a polypropylene-fire-retardant kraft laminate, (c) coating the HDPE-fire-retardant kraft or polypropylene-fire-retardant kraft laminate with from 3 to 10 pounds of LDPE per 3000 square feet of the HDPE-fire-retardant kraft laminate or polypropylene-fire-retardant kraft laminate to form an LDPE-HDPE-fire-retardant kraft laminate or an LDPE-polypropylene-fire-retardant kraft laminate, (d) adjusting the temperature of the LDPE-HDPE-fire-retardant kraft laminate or the LDPE-polypropylene-fire-retardant kraft laminate so that the LDPE becomes tacky while the HDPE or polypropylene remains solid, (e) providing a layer of fiberglass wool, and (f) contacting the LDPE layer of the LDPE-HDPE-fire-retardant kraft laminate or of the LDPE-polypropylene-fire-retardant kraft laminate with the fiberglass wool layer with pressure and cooling to bond the LDPE-HDPE-fire-retardant kraft laminate or LDPE-polypropylene-fire-retardant kraft laminate to the fiberglass wool layer to form a fiberglass insulation product.

The invention relates to a protection and/or insulation element (1, 8) comprising a plastic film (2). One face of said film (2b) is fixed to a layer of cellular plastic material (4) while the other face (2a) thereof comprises a removable-type adhesive coating (3). For the purpose of improved tearability, the aforementioned plastic film (2) is fixed to the layer of cellular plastic material (4) by means of a screen (9). The cellular plastic material is preferably a non cross-linked polyethylene foam with closed cells.
摘要:
A single membrane insulation material (10) including a nonwoven insulation mat (12), a fluoropolymer dispersion (13) surface coated to one side of the mat and a fluoropolymer film component (14) laminated to the thus coated side of the mat under conditions of elevated temperature and pressure. The coating has a depth of penetration which is less than the total thickness of said mat.

The composite duct system (10) includes a first, duct portion (12); a second, duct foam portion (14); and, a third duct portion (16). The first duct portion has a first surface for permitting a flowable medium to be conveyed adjacent thereto, and a second surface. The first duct portion is formed with a first fiber reinforced resin system. The second duct foam portion has a first surface bonded to the second surface of the first duct portion. The foam portion is formed of fire retarding material derived from a resin system. The third duct portion has a first surface bonded to a second surface of the foam portion. The third duct portion is formed of a second fiber reinforced resin system. Thus, a system is created having an internally sandwiched foam insulation.
摘要:
Elément de renforcement permettant de réaliser une structure tubulaire utilisable notamment pour la réfection de conduites, constitué par un support textile (1) pouvant être imprégné d'une résine non polymérisée, et qui est recouvert sur au moins une de ses faces d'une couche superficielle étanche (2), ledit support textile ayant une structure telle que lorsqu'il est mis sous une forme tubulaire, il possède la caractéristique de pouvoir se déformer radialement tout en étant bloqué sous un effort de traction dans le sens longitudinal. Il se caractérise en ce qu'il est constitué d'au moins deux bandes (4,5) de tissu chaine et trame (ou non tissé constitué de nappes superposées de fils longitudinaux et transversaux), se recouvrant sur la moitié de leur largeur et étant liées entre elles dans cette zone de manière à pouvoir glisser l'une par rapport à l'autre sous l'action d'une contrainte interne lorsque ledit élément est mis sous forme tubulaire.
摘要:
A heat shield (10;40) comprises one or more metal members (14,24;44,46) defining a rigid enclosure (12;42) having a substantially continuous heat-reflecting surface (26 or 32; 50 or 52). The shield also comprises a plurality of sheets (30;48) of smooth flexible metal foil within said enclosure. The sheets are arranged one above the other, extend generally parallel to the heat-reflecting surface, and are free to touch one another.
