E ai ki te ahua,ko nga momo taputapu tepu e toru he koretake o te heke o te monomer formaldehyde i raro i te waahi rokiroki makariri.
* I te 40 ℃, ko te heke o te formaldehyde mai i nga momo taputapu tepu e toru he iti iho i te 5 mg / kg, a ko te rohe kua whakaritea i roto i te EU he 15 mg / kg.
* I te 80 ℃ me runga ake, ka nui ake te heke o te formaldehyde i te rohe kua whakaritea.Ka piki ake te pāmahana rumaki, ka tino piki te hekenga.
* I te 80 ℃, ko te nui o te heke o te formaldehyde e whakaatu ana i te piki ohorere, ka eke ki te teitei ki te 100 ℃.
Ko nga hua whakamatautau e whakaatu ana ka piki ake te pāmahana rumaki, ka piki te tohu wehewehe, ka heke te kiato o te mata, ka heke te kanapa.NaKo nga taputapu tepu melamine ka whakakorehia te ngaruiti.Ka taea e taatau te whakamahi i te rūnanga whakakino ozone, i te wai whakakino ranei.
Inaianei, me titiro ki nga raraunga whakamatautau o Huafu melamine disc.Pūhui hanga melaminei mahia e Huafu Chemicals kua pahemoSGShe whakamatautau, he pai rawa te kounga.Mena he wheketere taputapu koe, tena koa whakapiri mai ki a maatau mo te utu pai me nga korero kore utu.
