Cov Kev Xav Tau Dab Tsi Yuav Tsum Tau Melamine Tableware Cov Khoom Siv Tau Txais?

Hauv lub neej niaj hnub no, tib neeg tau them nyiaj ntau dua rau kev noj qab haus huv.Lawv tsis tsuas yog saib xyuas cov zaub mov huv thiab huv, thiab seb nws puas tsim kev puas tsuaj rau kev noj qab haus huv, tab sis kuj tseem txhawj xeeb txog qhov cuam tshuam ntawm cov tais diav uas muaj cov khoom noj rau lub cev.Yog li cov qauv dab tsi uas nrov melamine tableware muaj nyob rau hauv cov nqe lus ntawm ntau lawm technology?

1.Cov khoom yuav tsum tau ua

(1) Cov khoom yuav tsum tau ua los ntawm 100% ntshiab melamine compound.Kev siv urea-formaldehyde resin lossis lwm yam khoom siv raw uas tsis ua raws li cov kev cai hauv tebchaws tau txwv nruj heev.

(2) Cov kev cai tsim nyog: Cov khoom siv raw rau kev tsim cov melamine tableware yuav tsum ua tau raws li cov qauv kev nyiam huv hauv lub tebchaws thiab cov qauv kev ua haujlwm, tsis muaj tshuaj lom thiab tsis qab, muaj kev cuam tshuam zoo, acid thiab alkali tsis kam.Tsis tas li ntawd, nws qhov kub thiab txias yuav tsum ncav cuag -30 ℃ to + 120 ℃;

2. Cov chaw tsim khoom melamine tableware yuav tsum tau txais daim ntawv pov thawj QS.

3. National standard base:GB9690-2009 "Sanitary Standards for Melamine-Formaldehyde Products for Food Containers and Packaging Materials" (Lub teb chaws tus qauv yog lub teb chaws tshiab tus qauv rau melamine tableware, saws rau lub ob hlis ntuj 24, 2009, thiab officially lub Cuaj Hli Ntuj 1, 2009 nqa tawm).

4. Cov kev txwv tshwj xeeb:

(1) Lub sensory Performance index molded cov khoom yuav tsum zoo li qub thiab du hauv cov xim, tsis muaj ntxhiab tsw txawv txav lossis lwm yam khoom.

(2) Lub cev thiab tshuaj ntsuas ntsuas
