1. , a kind of manufacturing process of catalytic nano material for far infrared radiation and element is characterized in that:

  • use F E2O 3, NiO, TiO 2In superfine ground rice (3-100nm), mix in the mixture of zirconium silicate ultra micro nano powder, through the ball milling mixing, granularity is not more than 2 μ

    m, the ball milling time was not less than 72 hours, through moulding process, firing process, make far-infrared radiation material again, wherein;

    the design of mixture of zirconium silicate ultra micro nano powder is;

    Zirconium silicate (Z rSiO 4) 51% Clay (AL 2O 3.2SiO 4) 22.6% Talcum (3M gO.4SiO 2.H 2O) 2.5% Nickel oxide (NiO) 3.0%Cobalt oxide (C oO) (contain 1%C O3O 4) 2.5% Iron protoxide (r-F E2O 3) 5.4% Titanium oxide (TiO 2) 3.5% Zinc oxide (ZnO) (containing 1%ZnS) 6.5%Manganse Dioxide (MnO 2) 3.0% moulding process;

    A, dry-pressing;

    powder is crossed 100 mesh sieves, adds 7% polyvinyl alcohol solution, mixes 800kg/cm thoroughly 2Compression moulding, drying is 6 hours under 60-80 ℃

    of temperature. B, hot-cast;

    under 150 ℃

    of temperature, preceding material oven dry 2 hours, add quiet (80 orders sieve) 5% of burnt wood, other adds 0.3% oleic acid, and ball milling is 4 hours again, discharging oven dry (150C) 1 hour, pouring in the paraffin wax of fusing (adding the cured or oleic acid of a small amount of honeybee) into stirs into pasty state, with cured machine in till do not have bubble.Firing process;

    A, dry-pressing formed, its firing temperature to 1350 ℃

    is incubated 2 hours, firing time about 17 hours altogether, 80 order quartz sand powder stopping composition.B is when heat is annotated casting process, at AL 2O 3Row'"'"'s cured (under 200 ℃

    of low temperature) is 8 hours in the-clay half and half, burns till then 10 hours to 1330 ℃

    , is incubated 2 hours.Then to take heat to form cellular for making powder, and high temperature only reaches 1300 ℃ and

    get final product, chilling but after, low temperature-30--40 ℃

    of processing is after 4 hours, fragmentation again, abrasive dust, standby below comminution by gas stream to the 2 μ

    m are just made far-infrared radiation material.
