Melamine formaldehyde cob (MF)yog ib qho resin tsim los ntawm polycondensation ntawm melamine thiab formaldehyde ua raw cov ntaub ntawv tom qab hydroxylation cov tshuaj tiv thaiv.
MF tau dav siv hauv chav ua noj, khoom ua si, khoom siv niaj hnub, khoom siv hluav taws xob thiab lwm yam haujlwmvim nws qhov zoo ntawm kev ua tau yooj yim thiab molding, siab qhov tseeb, zoo txhua yam muaj zog, kub tsis kam, nplaim hluav taws kub, rwb thaiv tsev, thiab corrosion kuj.
Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis thiab kev paub txog kev tiv thaiv ib puag ncig, cov teb chaws thoob ntiaj teb tau siv cov kev ntsuas xws li kev txwv tsis pub nkag mus rau hauv hav zoov thiab txwv tsis pub cov tais diav pov tseg, uas tau txhawb kev thov rau cov khoom lag luam melamine hauv kev lag luam hauv tsev thiab txawv teb chaws kom nce. xyoo dhau xyoo.Txawm li cas los xij, tus nqi tsim khoom ntawm cov khoom siv ntshiab melamine formaldehyde resin yog me ntsis siab dua, uas txwv nws qhov kev nce qib thiab daim ntawv thov rau qee yam.Yog li ntawd, melamine tableware nrog xyoob hmoov tshiab tsim nyob rau hauv kev lag luam melamine raws li ib tug muab tub lim yog ua nrov.Ntawm qhov tod tes, kev siv cov hmoov xyoob tuaj yeem txo cov nqi ntawm cov khoom yas melamine, thiab ntawm qhov tod tes, nws tuaj yeem ua rau kom muaj zog ntawm cov resin.
Raws li ib txwm muaj, cov khoom siv raw ntawm melamine xyoob tableware yog li 20% xyoob hmoov, 60% -70%melamine molding compound, thiab tus so yog xim thiab muab tub lim.Qee cov neeg muag khoom hauv khw yuav txhawb nqa tias xyoob melamine tableware yog ib puag ncig tus phooj ywg thiab biodegradable, tab sis qhov tseeb tsuas yog xyoob hmoov yog degradable.Yog li ntawd, nws yog ib qho tsim nyog rau cov tuam txhab tsim khoom lag luam kom kawm paub txog kev paub txog melamine xyoob tableware kom cov pej xeem muaj kev nkag siab zoo ntawm nws.
Huafu Chemicalyuav txuas ntxiv qhia txog kev tshaj lij thiab kev paub txog kev lag luam melamine yav tom ntej.
