1. Tsis txhob siv melamine tableware nyob rau hauv high-temperature ib puag ncig
Kev pab kub ntawm melamine tableware yog 0 ℃ to 120 ℃.Yog tias muab tso rau hauv cov roj kub kub ntawm 200 ℃ rau kaum feeb, nws yuav ua rau cov tais diav ua npuas thiab decompose.
Thaum foaming, ib feem ntawm melamine resin yuav decompose, cov txheej txheem no yuav tsim ntau formaldehyde thiab melamine.Lub sij hawm no yuav tsum tau hloov cov tais diav kom tsis txhob siv cov khoom.
Nws yog ib qho tsim nyog hais tias qee cov chopsticks hauv cov khw noj mov kub kuj siv melamine tableware.Vim muaj kev sib cuag nrog lub siab kub hauv qab lub lauj kaub thaum lub sij hawm ua noj ua haus, thiab lub sij hawm noj mov ntev.
Cov neeg ua haujlwm soj ntsuam zoo pom tias melamine tableware Tom qab cua sov ntawm 100 ℃ rau 3 teev, qhov kev tsiv teb tsaws ntawm melamine nyob rau hauv ib qho piv txwv mus txog qhov txwv tus nqi teev tseg los ntawm lub teb chaws tus qauv, thiab cov migration npaum li cas ntawm melamine yuav ntxiv nrog rau ncua sij hawm cua sov.
Yog li ntawd, nws yog txwv tsis pub siv melamine tableware dua nyob rau hauv qhov kub thiab txias.
2. Muab tso rau hauv dej kub kom paub tseeb tias cov khoom siv melamine tiag tiag los yog cuav
Vim tus nqi siab ntawmmelamine-formaldehyde resins,Qee cov tuam txhab tsis raug cai ncaj qha siv urea-formaldehyde resins ua raw khoom thiaj li nrhiav tau cov txiaj ntsig, thiab qee qhov siv urea-formaldehyde molding hmoov ua raw khoom.Ib txheej ntawm melamine hmoov yog siv, thiab cov khoom no tsis raug tso cai rau kev sib cuag nrog cov khoom noj hauv Suav teb.Thaum cov neeg siv khoom tiag tiag yuav, ntxiv rau kev xaiv cov khw muag khoom ib txwm muaj thiab cov khw muag khoom loj, tsis txhob xaiv "kev sib kis" pheej yig.
Vim tias qhov decomposition kub ntawm urea-formaldehyde resin yog li 80 ℃, thiab kev siv kub ntawm melamine tableware tuaj yeem ncav cuag 120 ℃, cov neeg siv khoom tuaj yeem nchuav dej kub rau hauv cov khoom tom qab kev yuav khoom melamine tableware.Yog hais tias muaj coob tus npuas tsim, nws yog fake melamine tableware.
Cov khoom siv raw rau kev tsim cov khoom noj-qib melamine tableware yog100% ntshiab melamine formaldehyde resin hmoov, thiab Huafu Chemical yog xws li melamine raw khoom chaw tsim tshuaj paus tshwj xeeb nyob rau hauv zus tau tej cov melamine molding compound rau zaub mov qib melamine tableware rau 20 xyoo.Tableware manufacturers uas xav tau melamine raw khoom nyob rau hauv tsev thiab txawv teb chaws txais tos hu rau kev sab laj.
