Urea utomoni sungagwiritsidwe ntchito pazakudya zilizonse.
Ndizosaloledwa kugwiritsa ntchito urea-formaldehyde resin kupanga pulasitiki, chifukwa imaphwanya muyezo wa China QB1999-1994 "melamine plastic tableware".N’chifukwa chiyani limanena choncho?
Chifukwa urea-formaldehyde utomoni sunatchulidwe mu 959 zowonjezera mu GB 9685-2009 muyezo, sungagwiritsidwe ntchito m'zakudya.
- Urea-formaldehyde resin tableware ndi yovulaza kwambiri mthupi la munthu chifukwa ndiyosavuta kuwola ngati ili ndi asidi amphamvu ndi alkali wamphamvu, ndipo imakhala ndi vuto la nyengo.
- Kugwiritsa ntchito nthawi yayitali kutentha kwa 80 ℃, urea-formaldehyde resin imakhudzidwanso kuti ipange urea ndi formaldehyde, formaldehyde yochulukira imakhala ndi zoopsa zomwe zingachitike mthupi la munthu.
The tableware opangidwa urea yokutidwa ndi melamine utomoni ufa singagwiritsidwe ntchito ngati chakudya kukhudzana tableware.
Chifukwa akadali urea-formaldehyde utomoni womwe ndi wosaloledwa kugwiritsidwa ntchito pa tableware kupanga.Pambuyo pa melamine ufa amatha, kotero ndi zovulaza ngati mankhwala urea.
Izi zitha kugwiritsidwa ntchito popanga mbale zopukutira, maswiti, mbale za zipatso, ndi zina zomwe sizimalumikizana mwachindunji ndi chakudya.
Choncho, zopangira kupanga chakudya kukhudzana melamine tableware n'kofunika kwambiri.
Ngati muli ndi zofunika msika mkulu-mapeto, monga zofunika okhwima melamine tableware m'misika European ndi America, mukhoza bwinobwino kusankhaHFM melamine ufa.
ChifukwaHuafu Melamine Molding Compoundyadutsa mayeso ovomerezeka a SGS ndi EUROLAB, ndipo Huafu Factory imangopangaufa woyera wa melaminekwa chakudya kukhudzana melamine tableware.Takulandilani opanga ma tableware kuti muyitanire zokambirana!
