  • Publication number: 20130095275
    Abstract: A lining and a related method for extending the period during which a line leg, such as a pipeline in a fireproofing installation, remains below a critical temperature are described. The lining includes, for example, a binding agent, endothermically degradable fillers and/or other fillers, if applicable. The method includes a wrapped line leg with the lining on both sides for wall feedthroughs and/or above the feedthrough opening for ceiling feedthroughs directly after the bulkheading of a feedthrough opening in a fireproofing installation. The heat removal from or the cooling of a line leg can be supported easily and applied on-site in such a way that even line legs with good thermal conductivity can achieve a high T-rating value in the fire test.

  • Publication number: 20110108758
    Abstract: The present invention provides a method of producing manufactured aggregates from a mPCM slurry, by combining a cementitious binder with the slurry in an agglomeration process. Also, other materials may be introduced (e.g., CaO). The agglomerated feed mix then goes through a curing and classification process to meet the size criteria of the end product. The invention also provides a method of manufacturing PCM aggregates that are substantially fire retardant by mixing the PCM particles with magnesium hydroxide or aluminum hydroxide. Water may be added to assure uniform distribution of particles with the hydroxide particles. Alternatively, the hydroxides may be obtained in situ by mixing magnesium oxide or aluminum oxide with water prior to mixing with the PCM particles.

  • Patent number: 7736696
    Abstract: A closed-loop system and process is used for applying fire retardant chemicals to substrates including fibers, yarns, fabrics or mixtures thereof. Substrates are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. The re-use of fire retardant chemicals can take place in the same vessel which is used to treat successive batches of substrates. Alternatively, recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.

  • Patent number: 6881470
    Abstract: Biaxially oriented, co-extruded polyester films comprising a base layer consisting of at least 90 wt. % thermoplastic polyester, preferably polyethylene terephthalate (PET), at least one sealable outer layer and a second non-sealable outer layer and, optionally, other intermediate layers, in addition to at least one flame-retardant agent, preferably organic phosphorous compounds. The inventive films are characterized by low inflammability, no embrittlement when subjected to thermal stress and a surface which is devoid of troublesome opacity, and are suitable for a multiplicity of uses both indoors and outside. The outer layers contain anti-blocking agents such as silicic acid having a particle diameter of preferably less than 50 nm and/or more than 2 ?m. Preferably, the sealable outer layer consists of a copolyester which is made of ethylene terephthalate and ethylene isophthalate units.

  • Patent number: 6821631
    Abstract: A method of treating substrates, such as wood, including the steps of applying an alkali silicate solution to one or more substrates and applying an alkali borate solution with boric oxide (B2O3) content to the substrates. Substrates that have been treated using the present method include a borate-silicate polymer within the substrate. When the present substrates are wood, wood products, or green lumber, they may be used to build structures.
