Donfoam 824PIR HFC-245fa te whakakotahi i nga polyols mo te paraka paraka PIR tonu
WHAKATOKANGA
Ko te DonFoam 824 / PIR he momo polyols whakakotahi ma te whakamahi i te kaihoko pahuka hfc-245fa, me te polyol hei rauemi mata matua, i konatunatua ki te kaihoko awhina motuhake, e tika ana mo te whakamaarama o te hanga, te kawe waka, te anga me etahi atu hua.Ko tenei rauemi he mea tino whakawhanakehia mo te raina tonu .Ko te hua polyurethane kua rite ma te tauhohe ki te isocyanate e whai ake nei nga painga:
-- He pai te taiao, me te kore e whakangaro i te paparanga ozone
-- Te kaha compressive teitei me te riterite pai o te kaha isotropic
-- He pai te mahi whakawera waiariki me te pumau o te taha
