I whakairihia ki runga 2018-03-21Ko te whakamahinga o te paninga dacromet, ko te nuinga o nga kamupene whakawera o te oumu whitiki mata e whakahaere ana i te pāmahana rohe preheat 80 ~ 120 ℃. na roto i te tukanga matū o te whakaheke i te chromium hexavalent na te waipiro.
Ko te tikanga mo tenei whakatau he ranunga o te Dacromet B parakore (aqueous chromic anhydride) me te polyethylene glycol reductant i te rahinga.I tunua te paninga ki runga i te kiriata karaihe ka whakamahana ki te 120°C mo te 15 meneti.Ka whakaeto te wai, ko te toenga he kiriata maku kakariki pouri.
Mena ka werahia te waahanga whakamatautau ki te 120 meneti, ka matomato te tae o te paninga, ka pakeke te paninga, engari ka taea te horoi ki te wai.Ma te mohio, kaore e taea te whakamahi i te whakamahana mo te wa roa i te 120°C hei whakahaere i te paninga o Dacromet.
