    摘要: A process for preparing a fiberglass insulation product, including the steps of: (a) providing a layer of kraft paper, (b) coating the 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-kraft laminate or a polypropylene-kraft laminate, (c) coating the HDPE-kraft or polypropylene-kraft laminate with from 3 to 10 pounds of LDPE per 3000 square feet of the HDPE-kraft laminate or polypropylene-kraft laminate to form an LDPE-HDPE-kraft laminate or an LDPE-polypropylene-kraft laminate, (d) adjusting the temperature of the LDPE-HDPE-kraft laminate or the LDPE-polypropylene-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-kraft laminate or of the LDPE-polypropylene-kraft laminate with the fiberglass wool layer with pressure and cooling to bond the LDPE-HDPE-kraft laminate or LDPE-polypropylene-kraft laminate to the fiberglass wool layer to form a fiberglass insulation product.

    摘要: By rapidly heating a precursor wire having a multifilamentary structure in which multiple composite cores in which a composite compound of an NbnullGa compound and Nb is embedded in Nb are embedded in Nb, Ta, Nb-base alloy or Tabase alloy as a matrix material to a temperature range of 1400 to 2100null C. in 2 seconds, quenching the precursor wire at a rate of 5000null C./second or larger, and subjecting the precursor wire to additional heat treatment at a temperature range of 600 to 850null C. for 1 to 400 hours, a superconducting wire having a multifilamentary structure in which multiple composite cores in which a composite compound containing Nb3Ga of a stoichiometric composition embedded in Nb are embedded in Nb, Ta, Nb-base alloy or Tabase alloy as a matrix material is obtained.
