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
-- Ko te kaha o te kopiri me te riterite pai o te kaha isotropic
-- He pai te mahi whakamaarama waiariki me te pumau o te taha
