Huafu Chemicalsiri kugovera imwe nyanzvi yekuyedza data pane formaldehyde kutama mune yakakwirira-tembiricha nezve melamine tableware.
Testing Method: soak 3% acetic acid mhinduro pane tembiricha dzakasiyana kwe 0.5 awa, 2 maawa.Tarisa mugumisiro uri pasi apa.
Mhedzisiro yekunyura tembiricha pane formaldehyde migration mg/kg

Maererano nenhamba,iwo matatu marudzi epatableware akanyanya mahara e formaldehyde monomer kutama pasi pekutonhora kwekuchengetedza mamiriro.
* Pa40 ℃, kutama kwe formaldehyde kubva kumhando nhatu dzetableware isingasviki 5 mg/kg, uye muganhu wakadzorwa muEU i15 mg/kg.
* Pa80 ℃ uye pamusoro, kutama kwe formaldehyde kunopfuura zvakanyanya muganho wakatarwa.Sezvo tembiricha yekunyudza ichiwedzera, huwandu hwekutama hunowedzera zvakanyanya.
* Pa80 ℃, huwandu hwekutama hwe formaldehyde hunoratidza kuwedzera kamwe kamwe, kusvika pakakwirira pa100 ℃.
Mhedzisiro yekuedza inoratidza kuti tembiricha yekunyudza inowedzera, iyo disociation degree inowedzera, density yepasi inodzikira, uye kupenya kunoderera.Sakamelamine tableware ndiyo microwave inorambidzwa.Tinogona kushandisa ozone disinfection cabinet kana disinfection liquid panzvimbo.
Zvino, ngatitarisei data rekuyedza reHuafu melamine disc.Melamine molding compoundyakagadzirwa neHuafu Chemicals yapfuuraSGSkuyedza, kunyangwe yakanakisa mumhando.Kana iwe uri mafekitori etafura, ndapota inzwa wakasununguka kutibata nesu nemutengo wakanakisa uye ruzivo rwemahara.
