I-resin ye-Urea ayinakusetyenziselwa i-tableware yoqhagamshelwano lokutya konke konke.
Akukho mthethweni ukusebenzisa i-urea-formaldehyde resin ukwenza i-tableware yeplastiki, kuba ixhaphaza umgangatho we-China QB1999-1994 "i-melamine plastiki tableware".Kutheni isitsho nje?
Ngenxa yokuba i-resin ye-urea-formaldehyde ayidweliswanga kwii-additives ze-959 kumgangatho we-GB 9685-2009, ayikwazi ukusetyenziswa kwizitya zokutya.
- I-Urea-formaldehyde resin tableware iyingozi kakhulu kumzimba womntu kuba kulula ukubola xa kukho iasidi eyomeleleyo kunye nealkali eyomeleleyo, kwaye inokumelana nemozulu embi.
- Ukusetyenziswa kwexesha elide kubushushu obuyi-80℃, i-urea-formaldehyde resin isabela ngokubuyisela umva ukuvelisa i-urea kunye ne-formaldehyde, i-formaldehyde egqithisileyo iya kuba nobungozi obunokubakho kumzimba womntu.
Itafile eyenziwe nge-urea egqunywe nge-melamine resin powder nayo ayinakusetyenziswa njengetafile yokudibana nokutya.
Kuba iseyi-urea-formaldehyde resin engekho mthethweni ukuba isetyenziselwe ukwenza itafile.Emva kokuba i-melamine powder igugile, ngoko inobungozi njengemveliso ye-urea.
Le mveliso ingasetyenziselwa kuphela ukwenza iipleyiti zetawuli, iipleyiti zeelekese, iipleyiti zeziqhamo, njl njl ezingadibanisi ngokuthe ngqo nokutya.
Ke ngoko, izinto ezikrwada zokwenza unxibelelwano lokutya i-melamine tableware ibaluleke kakhulu.
Ukuba uneemfuno zemarike eziphezulu, ezifana neemfuno ezingqongqo ze-melamine tableware kwiimarike zaseYurophu naseMelika, unokukhetha ngokukhuselekileyo.HFM melamine powder.
NgokubaHuafu Melamine Molding Compounduphumelele iimvavanyo eziqinisekisiweyo ze-SGS kunye ne-Intertek, kwaye i-Huafu Factory ivelisa kuphelai-melamine powder ecocekileyongokuba ukutya zoqhagamshelwano melamine tableware.Wamkelekile abavelisi betafile ukuba babize ukubonisana!
