I-Urea resin ayikwazi ukusetshenziselwa i-tableware yokudla.
Akukho emthethweni ukusebenzisa i-urea-formaldehyde resin ukwenza i-tableware yepulasitiki, ngoba ihlukumeza indinganiso yaseChina QB1999-1994 "melamine plastics tableware".Kungani lisho kanjalo?
Ngenxa yokuthi i-urea-formaldehyde resin ayifakiwe ohlwini lwezithasiselo ezingu-959 ezingeni le-GB 9685-2009, ayikwazi ukusetshenziswa ezitsheni zokudla.
- I-Urea-formaldehyde resin tableware iyingozi kakhulu emzimbeni womuntu ngoba kulula ukubola uma kune-asidi eqinile ne-alkali enamandla, futhi inokumelana nesimo sezulu esibi.
- Ukusetshenziswa isikhathi eside ezingeni lokushisa elingu-80℃, i-urea-formaldehyde resin isabela ngokuhlehlayo ukuze ikhiqize i-urea ne-formaldehyde, i-formaldehyde eyeqile izoba nezingozi ezingaba khona ze-carcinogenic emzimbeni womuntu.
I-tableware eyenziwe nge-urea embozwe nge-melamine resin powder nayo ayikwazi ukusetshenziswa njenge-tableware yokudla.
Ngoba iseyi-urea-formaldehyde resin engekho emthethweni ukuthi isetshenziselwe ukwenza i-tableware.Ngemuva kokuthi i-melamine powder igugile, ngakho futhi iyingozi njengemikhiqizo ye-urea.
Lo mkhiqizo ungasetshenziswa kuphela ukwenza amapuleti ethawula, amapuleti amaswidi, amapuleti ezithelo, njll okungathintana ngqo nokudla.
Ngakho-ke, izinto ezisetshenziswayo zokwenza ukuthintana nokudla kwe-melamine tableware kubaluleke kakhulu.
Uma unezidingo zemakethe ezisezingeni eliphezulu, njengezidingo eziqinile ze-melamine tableware ezimakethe zaseYurophu naseMelika, ungakhetha ngokuphepha.I-HFM melamine powder.
NgobaI-Huafu Melamine Molding Compounduphumelele ukuhlolwa okuqinisekisiwe kwe-SGS ne-Intertek, futhi i-Huafu Factory ikhiqiza kuphelai-melamine powder ehlanzekilefor ukudla contact melamine tableware.Siyakwamukela abakhiqizi be-tableware ukuze bacele ukubonisana!
